find the surface area of cuboid whose Length breadth and height are 15 CM 12 cm and 10cm respectively​

Answer:

22.8

Step-by-step explanation:

the rectangular has :

the length CD =√[(3+3)²+(0-5)²]

= √(36+25) = √61 = 7.8

the width BC =√[(5-3)²+(3-0)²]

=√(4+9 =√13 = 3.6

so, the perimeter = 2(7.8 + 3.6)

= 2× 11.4 = 22.8

Answer: 1/2 x 1/2 x 1/2 x 1/2

Step-by-step explanation:

The probability density function (pdf) of the largest of the five waiting times is given by: f(x) = 4/10^5 * x^4, where x is a real number between 0 and 10. The expected value of the largest of the five waiting times is 8.33 minutes.

The pdf of the largest of the five waiting times can be found by considering the order statistics of the waiting times. The order statistics are the values of the waiting times sorted from smallest to largest.

In this case, the order statistics are X1, X2, X3, X4, and X5. The largest of the five waiting times is X5.

The pdf of X5 can be found by considering the cumulative distribution function (cdf) of X5. The cdf of X5 is given by: F(x) = (x/10)^5

where x is a real number between 0 and 10. The pdf of X5 can be found by differentiating the cdf of X5. This gives: f(x) = 4/10^5 * x^4

The expected value of X5 can be found by integrating the pdf of X5 from 0 to 10. This gives: E[X5] = ∫_0^10 4/10^5 * x^4 dx = 8.33

Answer:

What is the question itself?

Answer:

80×t=d

Step-by-step explanation:

t means time so if the train travels 2 hours

80×2=160miles

is a growth

a) The equation with time(t) and distance(d) is 80 = d/t.

b) Domain is set of all x-coordinates and range is the set of all y-coordinates.

a) Given that, a train travels at 80 miles per hour.

We know that, speed = Distance/Time

Now, 80 = d/t

So, the equation is 80 = d/t

b) The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:

Domain = the set of all x-coordinates = {1, 2, 3, 4}

Range = the set of all y-coordinates = {2, 3}

Therefore,

a) The equation with time(t) and distance(d) is 80 = d/t.

Answer:

We first ALWAYS have to split the figure apart from each other,

lets split it into a triangle and a square!

Let's find the area of the triangle:

20(height) x 20(base) = 400!

400 x 1/2 (just dividing by 2) = 200!

*Remember* Formula of a triangle is:

B(base) x H(height) x 1/2 (basically dividing by 2)

Now time to find the area of the square!

20 x 20 = 400!

Now let's add both their areas:

400 + 200 = 600!

Step-by-step explanation:

600cm2 is your answer.

The figure has an area of 600 square centimeters.

In this question we need to determine the area of the entire figure, this area is the sum of the areas of a square and two symmetric right triangles, defined by respective formulas, that is:

\(A = A_{s} + 2\cdot A_{t}\) (1)

Where:

By applying area formulas for squares and triangles, we expand (1):

\(A = x^{2} + \frac{1}{2}\cdot x\cdot y\) (2)

Where:

If we know that \(x = 20\,cm\) and \(y = 20\,cm\), then the area of the figure is:

\(A = \frac{3}{2}\cdot (20\,cm)^{2}\)

\(A = 600\,cm^{2}\)

The figure has an area of 600 square centimeters.

A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. For any base n, q must be a factor of n in order for p/q to have a terminating base n representation.

A rational number p/q has a terminating base 60 representation if q is a factor of 60. This can be proven by noting that q is a factor of p if and only if the remainder of p divided by q is 0. This can be seen by noting that if q is a factor of p, then p can be written as a multiple of q, or p = kq, where k is an integer. Thus, p/q = k, and the remainder of p divided by q must be 0. If q is not a factor of p, then the remainder of p divided by q will not be 0. Thus, for a rational number p/q to have a terminating base 60 representation, q must be a factor of 60. To determine if q is a factor of n for any base n, we must again consider the remainder of p divided by q. If the remainder of p divided by q is 0, then q is a factor of n, and the rational number p/q will have a terminating base n representation. If, however, the remainder of p divided by q is not 0, then q is not a factor of n and the rational number p/q will not have a terminating base n representation.

Answer:

s = 150f

Step-by-step explanation:

A tropical punch recipe calls for 300 ml of sugar for every 2 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.

The amount of sugar in milliliters = s

The amount of flavor packages for these recipe = f

The relationship between 2 variables

= y ∝ x

y = kx

k = constant of proportionality

Hence:

s ∝ f

s = kf

Note ,

s = 300

f = 2

300 = 2k

k = 300/2

k = 150

Therefore, the equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe is:

s = kf

The solution of the given equation is x = 2.

Here we have the following equation that we want to solve, it is:

\(125^x = \frac{625}{5^{-x}}\)

We want to solve this for x, remember that a negative exponent means that we need to take the inverse, then we can rewrite the right side as:

\(125^x = \frac{625}{5^{-x}} = 625*5^x\)

Now we can divide both sides by 5^x to get:

\(125^x = \frac{625}{5^{-x}} = 625*5^x\\\\(125/5)^x = 625\\\\25^x = 625\\\\\)

Now we can apply the natural logarithm in both sides, we will get:

\(ln(25^x) = ln(625)\\\\x*ln(25) = ln(625)\\x = ln(625)/ln(25)\\\\x = 2\)

The number that goes in the square marked "X" is 33.

To solve this magic square, we first need to find the sum of all the numbers from 1 through 17, which is 153. Since we have nine squares in the magic square, and we know that the sum of each row, column, and diagonal is equal, we can divide 153 by 3, which gives us 51.

We can start by placing the number 1 in the middle square, and then place the odd numbers in a clockwise fashion around the center, starting from the top left corner. This gives us:

9 3 1
5 X 13
15 11 7

We can now check if the sum of each row, column, and diagonal is equal to 51.

Sum of first row: 9 + 3 + 1 = 13

Sum of second row: 5 + X + 13 = X + 18

Sum of third row: 15 + 11 + 7 = 33

Sum of first column: 9 + 5 + 15 = 29

Sum of second column: 3 + X + 11 = X + 14

Sum of third column: 1 + 13 + 7 = 21

Sum of first diagonal: 9 + X + 7 = X + 16

Sum of second diagonal: 1 + X + 15 = X + 16

We know that the sum of each row, column, and diagonal should be 51, so we can set up the following

X + 18 = 51
X + 14 = 51
X + 16 = 51
X + 16 = 51      Solving for X, we get X = 33.

We would expect approximately 438 SAT verbal scores to be greater than 525 out of a random sample of 1000 scores.

To find the percent of SAT verbal scores that are less than 550, we can use the normal distribution with the given mean and standard deviation.

First, we calculate the z-score corresponding to an SAT verbal score of 550 using the formula:

z = (x - μ) / σ

where x is the score, μ is the mean, and σ is the standard deviation.

z = (550 - 509) / 108

  ≈ 0.3796

Using a standard normal distribution table or a calculator, we find that the area to the left of z = 0.3796 is approximately 0.6480.

This means that approximately 64.80% of SAT verbal scores are less than 550.

To estimate the number of SAT verbal scores greater than 525 out of a random sample of 1000 scores, we can use the same information.

First, we find the z-score corresponding to a score of 525:

z = (525 - 509) / 108

  ≈ 0.1481

Next, we find the area to the right of z = 0.1481, which is the probability of a score being greater than 525:

1 - 0.5616 ≈ 0.4384

The probability of a score being greater than 525 is approximately 0.4384.

To estimate the number of scores greater than 525 out of a sample of 1000, we multiply the probability by the sample size:

0.4384 * 1000 ≈ 438.4

The length of third side is in between 33.33 and 132.83.

The theorem that the sum of any two sides of a triangle is greater than or equal to the third side is known as the triangle inequality in Euclidean geometry. The theorem basically states that a straight line defines the shortest distance between two points.

Other metric spaces, or spaces that contain a means of measuring distances, have counterparts to the triangle inequality.

Given two sides of triangle are 33.33 yards and 99-100 yards(say 99.5)

There is a triangle here. Since it is not a right triangle, we must employ triangle inequality to determine the third side's length.

The longer side, 99.5 yards must be shorter than the sum of the other two sides. If the second side is c, then

99.5 < 33.33 + c.

The side c must be longer than 33.33

The side c must be shorter than the sum of the other two sides:

c < 99.5 + 33.33.

c < 132.83

Combining both we will get that

33.33  <  c  <  132.83.

This interval (33.33, 132.83) gives all the lengths the third side of the triangle can have.

Hence the length of third side varies between 33.33 and 132.83.

The combined present worth of the costs associated with the proposed bridge design, including construction and annual operating costs, is $10,583,333.

To calculate the combined present worth of costs, we need to consider the construction cost and the annual operating cost over the infinite life of the bridge. We will use the concept of present worth, which is the equivalent value of future costs in today's dollars.

The present worth of the construction cost is simply the initial cost itself, which is $9,000,000. This cost is already in present value terms.

For the annual operating cost, we need to calculate the present worth of perpetuity. A perpetuity is a series of equal payments that continue indefinitely. In this case, the annual operating cost of $700,000 represents an equal payment.

To calculate the present worth of the perpetuity, we can use the formula PW = A / MARR,

where PW is the present worth, A is the annual payment, and MARR is the minimum attractive rate of return (also known as the discount rate). Here, the MARR is given as 12%.

Plugging in the values, we have PW = $700,000 / 0.12 = $5,833,333.

Adding the present worth of the construction cost and the present worth of the perpetuity, we get $9,000,000 + $5,833,333 = $14,833,333.

However, since we are looking for the combined present worth, we need to subtract the salvage value, which is zero in this case. Therefore, the combined present worth of the costs associated with the proposed bridge design is $14,833,333 - $4,250,000 = $10,583,333, rounded to the nearest dollar.
