How many inches in 900 mm?
900 millimeters is equivalent to 35.433070866 inches.
Inches and millimeters are both units of measurement for length. To convert from millimeters to inches, we can use the conversion factor that 1 inch is equal to 25.4 millimeters. To convert 900 millimeters to inches, we can multiply 900 by the conversion factor.
The formula for converting millimeters to inches is:
inches = millimeters / 25.4
So in this case:
inches = 900 / 25.4
After doing the calculation, we find that 900 millimeters is equivalent to 35.433070866 inches.
It's important to note that the conversion factor is a constant value which is used multiple times during the conversion process.

Grant plans to evaporate enough water from 22 gallons of a 16% ammonia solution to make a 24% ammonia solution. Which equation can he use to find n, the number of gallons of water he should remove?
3.52 (22 minus n) = 0.24
StartFraction 22 minus n Over 3.52 EndFraction = StartFraction 24 Over 100 EndFraction
StartFraction 3.52 Over 22 minus n EndFraction = StartFraction 24 Over 100 EndFraction
3.52 + (22 minus n) = 0.24
The equation that he used to find n, the number of gallons of water he should remove is 3.52 / (22 - n) = 24 / 100. Option C is correct.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Amount of ammonia in the solution 16% x 22 gallons = 3.52 gallons
The proportion of ammonia remains the same as the water evaporates, but the total composition of the solution is decreased by the amount of water that evaporates.
Quantity of ammonia = 3.52 gallons
Quantity of water after evaporation = 22 - n
Composition of ammonia after evaporation of water, 24% = 24/100
Now the percentage of ammonia after evaporates
Quantity of ammonia / Remaining water = 24%
3.52 / (22 - n) = 24 / 100
Thus, the equation that he used to find n, the number of gallons of water he should remove is 3.52 / (22 - n) = 24 / 100.

A coin is flipped, and a number cube is rolled. what is the probability of getting tails on the coin and an even number on the number cube?
The probability of getting tails on the coin and an even number on the number cube is 1/4
What are probabilities?Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events
How to determine the probability?The sample space of a coin is:
S = {H, T}
The sample space of a die is:
S = {1, 2, 3, 4, 5, 6}
The above means that:
A coin has 2 faces, one of which is the tail.
So, we have:
P(Tail) = 1/2
A number cube has 6 numbers, 3 or which are even.
So, we have
P(Even) = 3/6
The required probability is
P = P(Tail) * P(Even)
This gives
P = 1/2 * 3/6
Evaluate
P = 1/4
Evaluate the quotient
P = 0.25
Hence, the probability of getting tails on the coin and an even number on the number cube is 1/4 or 0.25

let p and q be distinct primes. (1) prove that (z/(pq))× has order (p − 1)(q − 1);
The order of a in (z/(pq))× is exactly (p-1)(q-1), as desired.
To prove that (z/(pq))× has order (p − 1)(q − 1), we need to show that the least positive integer n such that (z/(pq))×n = 1 is (p − 1)(q − 1).
First, let's define (z/(pq))× as the set of all integers a such that gcd(a,pq) = 1 (i.e., a is relatively prime to pq) and a mod pq is also relatively prime to pq.
Now, we know that the order of an element a in a group is the smallest positive integer n such that a^n = 1. Therefore, we need to find the order of an arbitrary element a in (z/(pq))×.
Let's assume that a is an arbitrary element in (z/(pq))×. Since gcd(a,pq) = 1, we know that a has a multiplicative inverse modulo pq, denoted by a^-1. Therefore, we can write:
a * a^-1 ≡ 1 (mod pq)
Now, let's consider the order of a. Since gcd(a,pq) = 1, we know that a^(p-1) is congruent to 1 modulo p by Fermat's Little Theorem. Similarly, we can show that a^(q-1) is congruent to 1 modulo q. Therefore, we have:
a^(p-1) ≡ 1 (mod p)
a^(q-1) ≡ 1 (mod q)
Now, we can use the Chinese Remainder Theorem to combine these congruences and get:
a^(p-1)(q-1) ≡ 1 (mod pq)
Therefore, we know that the order of a must divide (p-1)(q-1).
To show that the order of a is exactly (p-1)(q-1), we need to show that a^k is not congruent to 1 modulo pq for any positive integer k such that 1 ≤ k < (p-1)(q-1).
Assume for contradiction that there exists such a k. Then, we have:
a^k ≡ 1 (mod pq)
This means that a^k is a multiple of pq, which implies that gcd(a^k, pq) ≥ pq. However, since gcd(a,pq) = 1, we know that gcd(a^k, pq) = gcd(a,pq)^k = 1. This is a contradiction, and therefore our assumption must be false.

max rides his scooter toward kim and then passes her at a constant speed. his distance in feet, d, from kim t seconds after he started riding his scooter is given by d
The distance, d, in feet from Kim t seconds after Max started riding his scooter is given by the equation d = st, where s is the constant speed at which Max is riding his scooter.
To find the distance, d, we need to multiply the speed, s, by the time, t. Since Max passes Kim at a constant speed, the distance he travels is directly proportional to the time elapsed.
Therefore, the equation d = st represents this relationship, where d is the distance, s is the speed, and t is the time.
The equation d = st allows us to calculate the distance, d, from Kim t seconds after Max started riding his scooter, provided we know the constant speed, s, at which Max is traveling. By multiplying the speed by the time, we can determine how far Max has traveled from Kim at any given moment. This equation assumes that Max maintains a constant speed throughout his journey and that the speed does not change.

Find the area of the region below y = x2 + 2x – 2 and above y = 5 for 2
To find the area of the region below the curve y = x^2 + 2x - 2 and above the line y = 5, we need to determine the intersection points of the two curves and then calculate the area between them.
Step 1: Find the intersection points. Set the two equations equal to each other: x^2 + 2x - 2 = 5. Rearrange the equation to bring it to the standard quadratic form: x^2 + 2x - 7 = 0. Solve this quadratic equation for x using factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:x = (-2 ± √(2^2 - 41(-7))) / (2*1)
x = (-2 ± √(4 + 28)) / 2
x = (-2 ± √32) / 2
x = (-2 ± 4√2) / 2
x = -1 ± 2√2. So the two intersection points are: x = -1 + 2√2 and x = -1 - 2√2. Step 2: Calculate the area. To find the area between the two curves, we integrate the difference between the two curves with respect to x over the interval where they intersect.
The area can be calculated as follows: Area = ∫[a, b] (f(x) - g(x)) dx. In this case, f(x) represents the upper curve (y = x^2 + 2x - 2) and g(x) represents the lower curve (y = 5). Area = ∫[-1 - 2√2, -1 + 2√2] [(x^2 + 2x - 2) - 5] dx. Simplify the expression: Area = ∫[-1 - 2√2, -1 + 2√2] (x^2 + 2x - 7) dx. Integrate the expression: Area = [(1/3)x^3 + x^2 - 7x] evaluated from -1 - 2√2 to -1 + 2√2. Evaluate the expression at the upper and lower limits:Area = [(1/3)(-1 + 2√2)^3 + (-1 + 2√2)^2 - 7(-1 + 2√2)] - [(1/3)(-1 - 2√2)^3 + (-1 - 2√2)^2 - 7(-1 - 2√2)]. Perform the calculations to obtain the final value of the area. Please note that the calculations involved may be quite lengthy and involve simplifying radicals.

Answer: 108ft^2
Step-by-step explanation:
First, at the top we have two triangle rectangles.
The area of a triangle rectangle is equal to the product of their cathetus divided by two.
We know that one common cathetus for both triangles is 6ft.
And both share the bottom line that is 14ft long, so half of that corresponds to each triangle.
14ft/2 = 7ft
Then each triangle has a cathetus of 6ft and one of 7ft.
Then the area of each triangle rectangle at the top is:
6ft*7ft/2 = 21ft^2
And we have two of them, so the area for now is:
A1 = 21ft^2 + 21ft^2 = 42ft^2.
Now let's look at the bottom part, we can divide this into two triangle rectangles and one rectangle.
First, bottom side is 8ft, then the difference between this side and the 14ft one is:
14ft - 8ft = 6ft
(We calculate this because we are making a rectangle, then the bottom side length must be equal than the top one).
Then we have a surpass of 6ft, which we will divide into both triangle rectangles (3ft for each, this is one of the cathetus).
And we can see that the cathetus shown of this triangle rectangle is 6ft (this is also the other side of our rectangle)
Then we have two triangles with cathetus 6ft and 3 ft, the area is:
A = 6ft*3ft/2 = 9ft^2
And we have two of them, then A2 = 18ft^2.
And the rectangle is 8ft by 6ft, the area is:
A3 = 8ft*6ft = 48ft^2
Then if we add all the areas that we found, we have:
A1 + A2 + A3 = 42ft^2 + 18ft^2 + 48ft^2 = 108ft^2

if p = 2-5 and q = 8x3 find 3p-q
Answer:
3p - q = 3(2-5) - (8x3) = -9 - 24 = -33. Therefore, 3p-q=-33.
The population of a 24-storey building is 600 persons. The contract speed of each lift is 4 m/s. The client intends to achieve an up peak interval of not more than 32 s with the expected up peak demand not less than 20%. The inter-floor height is 8 m. The door opening time is 2 s. The door closing time is 2 s The passenger loading time is 0.8 s. The passenger unloading time is 0.8 s. The single floor flight time is 5 s. Determine: (a) the minimum up-peak handling capacity (UPPHC); (b) the minimum contract capacity (CC); ): (C) the average highest call reversal floor (H) and the average number of stops (S); (d) the round trip time (RTT); (e) the number of lift required (L); and (f) the real up peak interval (UPPINT). Hence, comment whether the quality of the lift system is excellent acceptable or others.
The given data are:N = 600; G = 24; S = 4 m/s; Up-peak interval = 32 s; Expected up-peak demand = 20%; h = 8 m; Door opening time = 2 s; Door closing time = 2 s; Passenger loading time = 0.8 s;
Passenger unloading time = 0.8 s; Single floor flight time = 5 s; Hence, the minimum up-peak handling capacity (UPPHC) is 20% of 600 persons as per the question. Thus, UPPHC = (20/100) × 600=120 persons.
(a) Minimum up-peak handling capacity (UPPHC): UPPHC = 120 persons.
(b) Minimum contract capacity (CC): The formula for CC is given byCC = [(UPPHC × 3600)/Up-peak hours] = [(120 × 3600)/4] = 10800 persons/hr.
Hence, the minimum contract capacity is 10800 persons/hr.
(c) Average highest call reversal floor (H) and the average number of stops (S):
The formula for the average highest call reversal floor isH = [n/(n – 1)] × [∑f/(n × P)].
Where, n = number of lifts; ∑f = sum of the products of the number of floors served and the corresponding number of calls; and P = ∑f/number of floors served. Thus, H = [n/(n – 1)] × [∑f/(n × P)]For S, the formula is given by
S = ∑f/(n × P).
Thus, for calculating H and S, the traffic calculation is done, and the calculations are provided below:
For traffic design, let n = 3. Then, Np = UPPHC/up-peak hour= (120 × 3600)/3600=120 persons/hr.
Let the average number of stops be S. Then the number of floors served on the average during the up-peak hour is given by 24/S.
From the traffic flow diagram, the average highest call reversal floor is (3/2) H
= [3/(3 – 1)] × [((1 × 2) + (2 × 4) + (3 × 7) + (4 × 8) + (5 × 9) + (6 × 10) + (7 × 10) + (8 × 9) + (9 × 8) + (10 × 7) + (11 × 6) + (12 × 5) + (13 × 4) + (14 × 2))/(3 × 12)] = (3/2) × 7.63 = 11.45 ≈ 11 th floor.
∴ Average highest call reversal floor, H = 11th floor.∴ The average number of stops,
S = ∑f/(n × P)= [(1 × 2) + (2 × 4) + (3 × 7) + (4 × 8) + (5 × 9) + (6 × 10) + (7 × 10) + (8 × 9) + (9 × 8) + (10 × 7) + (11 × 6) + (12 × 5) + (13 × 4) + (14 × 2)]/3 × 12 × 1= 526/36= 14.61 ≈ 15.
(d) Round trip time (RTT):The formula for RTT is given by RTT = 2 × [L × (h/S) × Single floor flight time + Door open and closing time + Passenger loading and unloading time].
Where, L = number of lifts required to provide the UPPHC during the up-peak hour.
Thus, the calculation for L is done first as:
L = UPPHC/[(h/S) × Single floor flight time × 3600/up-peak hour]Now, substituting the given values in the above formula, we get,L = 120/[(8/4) × 5 × 3600/240] = 5 lifts(approx.)
Now, substituting the above value of L in the formula for RTT, we get
RTT = 2 × [5 × (8/4) × 5 + 2 + 0.8 + 0.8] = 94 s(approx.).Thus, the round trip time (RTT) is 94 s.
(e) Number of lifts required (L): We have already calculated the value of L, which is equal to 5 lifts.
(f) Real up peak interval (UPPINT):The formula for the real up-peak interval is given by:
Real up peak interval = (RTT × Number of cycles per hour)/(60 × Number of lifts required)Where the number of cycles per hour is given by 3600/RTT.
Hence, the value of the number of cycles per hour is equal to 3600/94, which is approximately equal to 38.298.
Now, substituting all the above values in the formula, we get
Real up peak interval = (94 × 38.298)/(60 × 5) = 30.06 s(approx.).Hence, the real up-peak interval (UPPINT) is 30.06 s.
The quality of the lift system is excellent since the real up-peak interval is less than the up-peak interval of 32 s, which was the expected value.

Find the average rate of change of f(x) = -11√x + 14 over the interval [-10, -9].
Write your answer as an integer, fraction, or decimal rounded to the nearest tenth. Simplify
any fractions.
The average rate of change of f(x) = -11√x + 14 over the interval [-10, -9]. is 0.7
What is the average rate of change?The average Rate of Change of the function f(x) can be calculated as;
\(f(x) = \dfrac{f(b) - f(a)}{b-a}\)
We have been given the function as; f(x) = -11√x + 14 over the interval [-10, -9].
i.e. a = -10 and b = -9
Therefore, f(x) = -11√x + 14
f(-9) = -11√(-9) + 14
f(-9) = -33 + 14
f(-9) = -19
Also, f(-10) = -11√(-10) + 14
f(-10) = - 34.7 + 14
f(-10) = 20.7
Now, substitute the values;
\(f(x) = \dfrac{f(b) - f(a)}{b-a}\\f(x) = \dfrac{f(-9) - f(-10)}{-9+ 10}\\f(x) = \dfrac{-19-20.7}{1}\\f(x) = 0.7\)
Hence, the average rate of change of f(x) = -11√x + 14 over the interval [-10, -9]. is 0.7

what is the slope for a line that is parallel to the line y=2/5x-4
Answer:
2/5
Step-by-step explanation:
The slope of the line
y=2/5x-4
is 2/5 since it is in the form y = mx+b where m is the slope
Parallel lines have the same slope so a line that is parallel to y=2/5x-4 has a slope of 2/5

In Exercises 43 through 46, solve the given separable initial value problem. 43. dx/dy =−2y;y=3 when x=0 44. dx/dy =xy;y=1 when x=0 45. dx/dy = e^x+y
;y=0 when x=0 46. dx/dy = √(y/x);y=1 when x=1
The solution to the initial value problem is √x = (1/3) \(y^{\frac{3}{2} }\) + 2/3.
Given: dx/dy = -2y, y = 3 when x = 0
To solve this, we'll separate the variables and integrate:
dx = -2y dy
Integrating both sides:
∫ dx = ∫ -2y dy
x = - \(y^{2}\) + C
Now we can apply the initial condition y = 3 when x = 0:
0 = - \(3^{2}\) + C
C = -9
Therefore, the solution to the initial value problem is x = - \(y^{2}\) - 9.
Given: dx/dy = xy, y = 1 when x = 0
We'll again separate the variables and integrate:
dx = xy dy
Integrating both sides:
∫ dx = ∫ xy dy
x = (1/2)\(y^{2}\) + C
Applying the initial condition y = 1 when x = 0:
0 = (1/2) \(1^{2}\) + C
C = -1/2
Thus, the solution to the initial value problem is x = (1/2)\(y^{2}\) - 1/2.
Given: dx/dy = \(e^{x+y}\), y = 0 when x = 0
Separating the variables and integrating:
dx = \(e^{x+y}\) dy
∫ dx = ∫ \(e^{x+y}\) dy
x = \(e^{x+y}\) + C
Using the initial condition y = 0 when x = 0:
0 = \(e^{0+0}\) + C
C = -1
Hence, the solution to the initial value problem is x = \(e^{x+y}\) - 1.
Given: dx/dy = √(y/x), y = 1 when x = 1
Again, separating the variables and integrating:
dx/√x = √y dy
Integrating both sides:
2√x = (2/3)\(y^{\frac{3}{2} }\) + C
Simplifying:
√x = (1/3)\(y^{\frac{3}{2} }\) + C
Applying the initial condition y = 1 when x = 1:
1 = (1/3)\(1^{\frac{3}{2} }\) + C
C = 2/3
Therefore, the solution to the initial value problem is √x = (1/3) \(y^{\frac{3}{2} }\) + 2/3.

Express the formula d=rt in terms of the time,t. Use your formula to find the time when the distance is 40 and the rate is 8.
The expression for d=rt in terms of the time is t = d/r; t = 5.
What is time? Time can be defined as a continuous and ongoing sequence of events that occur consecutively from the past to the present to the future. Time is used to measure, measure or compare the duration of events or the intervals between them, and even the sequence of events. Time is a useful concept that we use in our daily life. We have to watch when we cook, play, study, go to school, meet someone, etc. So knowing the right time is very important. Time is usually the answer to when an event happens or happened. The concept of time determines when a certain event occurs, has occurred or will occur. Time is a measurable quantity and is also infinite. The time is calculated in seconds, minutes, hours, days, months and years.Therefore,
In the equation d=rt
t = d/r
when distance is 40 and the rate is 8
t = d/r
Replace d with 40 and rate with 8
t = 40/8

Two people are trying to raise an object from a hole using two ropes, as shown in the diagram below. Person 1 exerts a force of
355 N and Person 2 exerts a force of 425 N.
What is the magnitude of the combined force applied by both people?
Answer:
554 N
Step-by-step explanation:
We're looking for the magnitude of the force - angles don't matter.
We need to resolve the two forces.
As you can see in the attached drawing, this basically just becomes Pythagoras.
\( {f}^{2} = {355}^{2} + {425}^{2}\)
\(f = \sqrt{ {355}^{2} + {425}^{2} } \)
\(f = 553.76\)
