Abandoned mines frequently fill with water. Before an abandoned mine can be reopened, the water must be pumped out. The size of pump required depends on the depth of the mine. If pumping out a mine that is D feet deep requires a pump that pumps a minimum of + 4D – 250 gallons per minute, pumping out a mine that is 150 feet deep would require a pump that pumps a minimum of how many gallons per minute?

Answer:

a=35

b=20

Step-by-step explanation:

a+b =55

a=b+15

b+15 +b =55

2b=55 - 15

2b=40

b=40 :2

b=20 (the smallest number)

a=20 +15 =35 (the largest number)

The number that makes the ratio equivalent to 7:5 is 70 when compared with 50. To find this, we can set up a proportion and solve for the unknown value.

Step 1: Set up the proportion
First, we can set up the proportion with the given ratio 7:5 and the unknown value (let's call it "x") compared to 50:
(7/5) = (x/50)

Step 2: Cross-multiply
Next, we can cross-multiply to find the equivalent value:
7 * 50 = 5 * x

Step 3: Solve for x
Now, we can solve for the unknown value "x":
350 = 5x
x = 70

So, the number that makes the ratio equivalent to 7:5 when compared with 50 is 70. The resulting equivalent ratio is 70:50.

The height of the tower is 969 feet.

Let CD be the tower and A be the point from a window in the building, a person determines that the angle of elevation to the top of the tower is 42 degrees.

In triangle AED

tan42° = ED/AE

tan42° = h₁/615

h₁ = tan42° × 615

= 553.74

Rounding to the nearest integer

h₁ = 554

In triangle AEC

tan34° = EC/AE

tan34° = h₂/615

h₂ = tan34° × 615

= 414.82

Rounding to the nearest integer

h₂ = 415

Height of tower = EC + ED

= h₁ + h₂

= 554 + 415

= 969

Therefore, the height of the tower is 969 feet.

This criterion can be defined based on the desired level of accuracy or when the change in the estimated parameters falls below a certain threshold.

When implementing a program for a nonlinear problem using the least square adjustment technique, it is essential to determine a termination condition. This condition dictates when the program should stop iterating and provide the final estimated parameters. A common approach is to set a convergence criterion, which measures the change in the estimated parameters between iterations.

One possible criterion is to check if the change in the estimated parameters falls below a predetermined threshold. This implies that the adjustment process has reached a point where further iterations yield minimal improvements. The threshold value can be defined based on the desired level of accuracy or the specific requirements of the problem at hand.

Alternatively, convergence can also be determined based on the objective function. If the objective function decreases below a certain tolerance or stabilizes within a defined range, it can indicate that the solution has converged.

Considering the chosen termination condition is crucial to ensure that the program terminates effectively and efficiently, providing reliable results for the nonlinear problem.

Answer:

The loudness of the sound is equal to 40 decibels.

Step-by-step explanation:

Given that,

The loudness (L) of sound in decibels is related to intensity by the equation as follows :

\(L=10\ log(\dfrac{I}{I_0})\)

Where

I is the intensity of sound

I₀ is the least audible sound

Put \(I=10^{-12}\ W/m^2 \ and\ I_0=10^{-16}\ W/m^2\)

So,

\(L=10\ log(\dfrac{10^{-12}}{10^{-16}})\\\\L=40\ dB\)

So, the loudness of the sound is equal to 40 decibels.

Answer:

Step-by-step explanation:

Point p is deflected across the y axis to obtain point q (5,-6) and across the x axis to obtain point r (-5,6).

A point on a grid has two numbers to identify its position. These numbers are known as coordinates. Coordinates are always written as the number of steps across first, then the number of steps up or down. Grids have two axes. The horizontal axis is called the x-axis and the vertical axis is called the y-axis.

We know that,

if point (x, y) deflected across y axis then the y coordinate remain same but the polarity of x gets change then

r(x, y) → (-x, y)

Similarly, if point (x, y) deflected across x axis then the x coordinate remain same but the polarity of y gets change then

r(x, y) → (x,-y)

Now, we have : p = (-5,-6)

As Point p is deflected across the y-axis to obtain point q , thus

r(-5,-6) → (5,-6)

point p is deflected across the x-axis to obtain point r, thus

r(-5,-6) → (-5,6)

Thus,  q=(5,-6) and r=(-5,6).

The phase change line, also known as the phase boundary or phase transition line, is a line on a graph that represents a change in conditions for a substance. This line shows the temperature and pressure conditions at which a substance will change from one phase to another, such as from a solid to a liquid or from a liquid to a gas.

The phase change line is represented on a graph by a diagonal line that separates two regions where the substance is in different phases. This line usually slopes upwards from left to right, indicating that higher temperatures and pressures are needed to change the substance from one phase to another.

The phase change line is an important concept in thermodynamics and is used to understand the behavior of substances under different conditions. For example, the phase change line for water shows that at normal atmospheric pressure, water will freeze at 0°C and boil at 100°C. However, at higher pressures, the freezing and boiling points will change, and water may exist in different phases, such as a supercritical fluid.

From the question, we have the following parameters that can be used in our computation:

intersecting secants

Using the theorem of intersecting secants, we have the following equation

a * b = c * d

In this case, we have

a = AE = 2

b = AB = 8

c = x

d = 10

Substitute the known values in the above equation, so, we have the following representation

2 * 8 = x * 10

Divide both sides by 10

x = 1.6

Hence, the value of x is 1.6

The value of dfbetween in the analysis of variances is 2. Thus option D is correct option.

According to the statement

we have given that the df total = 29 and df within = 27. And we have to find the value of the df between.

So, For this purpose, we know that the

Analysis of variance (ANOVA) is an analysis tool used in statistics that splits an observed aggregate variability found inside a data set into two parts.

So, Df between values are the values between the value of dftotal and dfwithin.

Here df total = 29 and df within = 27

So, df between = df total - df within

Substitute the values in it then

df between = df total - df within

df between = 29 - 27

df between = 2.

So, The value of dfbetween in the analysis of variances is 2. Thus option D is correct option.

Answer:

Step-by-step explanation:

Step 1:  Find the amount Elmer's funds decreased after purchasing the rabbits:

Let x represent Elmer's funds.

Since Elmer bought five rabbits for $10 each, he lost $10 5 times.

x - (10 * 5)

x - 50

Thus, Elmer lost (spent) $50 for the 5 rabbits.

Step 2:  Find the amount Elmer's funds decreased after purchasing the  cupboards:

Since Elmer bought four cupboards for $70 each, he lost $70 4 times:

x - (50 + (70 * 4))

x - (50 + 280)

x - 330

Thus, after purchasing the rabbits and cupboards, Elmer lost $330.

Step 3:  Find the amount Elmer's funds increased after finding the twenty-dollar bill:

Since Elmer found a twenty-dollar bill, he gained $20

x - (330 + 20)

x - 310

Step 4:  Find the amount Elmer's funds increased after returning one rabbit:

Since Elmer returned one rabbit, he gained $10:

x - (310 + 10)

x - 300

Thus, Elmer's funds changed totally by -$300.

Putting all the information together, we have:

x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10

x - 50 - 280 + 30

x - 330 + 30

x - $300

r = R/100 = 15%/100 = 0.15 per year,

putting time into years for simplicity,

3 months ÷ 12 months/year = 0.25 years,

then, solving our equation

I = 40000 × 0.15 × 0.25 = 1500
