Just use this equation:

1500/75=20

Which means its 12!

If you need anymore help feel free to ask me!

Hope this helps!

Answer:
20 inches

Explanation:
We are given that:
1 inch represents 75 miles
Therefore,
To solve this question, we will simply use cross multiplication as follows:
1 inch ..................> 75 miles
?? inches ............> 1500 miles

Number of inches = (1500*1) / (75) = 20 inches

3. A prop for the theater club’s play is constructed as a cone topped with a half-sphere. What is the volume of the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi.
14ich long 9inch wide half of shape with dotted line

Answers

1. To solve this problem you must sum the volume of the cone and the volume of the hemisphere. This means that the volumen of the prop is:

Vt=Vc+Vh

Vt is the volumen of the prop.
Vc is the volumen of the cone.
Vh is the volume of the hemisphere.

2. The volume of the cone (Vc) is:

Vc=1/3(πr²h)

r=9 in
h=14 in
π=3.14

4. Then, you have:

Vc=(3.14)(9 in)²(14 in)/3
Vc=3560.76 in³/3
Vc=1186.92

5. The volume of the hemisphere (Vh) is:

Vh=2/3(πr³)

π=3.14
r=9 in

6. Then, you have:

Vh=(2)(3.14)(9 in)³/3
Vh=4578.12 in³/3
Vh=1526.04 in³

7. Finally, the volumen of the prop (Vt) is:

Vt=Vc+Vh
Vt=1186.92 in³+1526.04 in³
Vt=2713.0 in³

What is the volume of the prop?

The volume of the prop is 2713.0 in³

A 3 lb bag of one brand of cat food costs $3.52. A 6 lb bag of another brand costs $6.80. Which brand is cheaper per pound?

Answers

A 6 lb bag of another brand

For this case what we should do is find the price per pound of each of the brands of cat food.
We have then:
Mark 1:
3 lb costs $ 3.52
P = (3.52) / (3) = 1.17 $ / lb
Mark 2:
6 lb costs $ 6.80
P = (6.80) / (6) = 1.13 $ / lb
Answer:
Mark 2 is cheaper per pound:
1.13 $ / lb

Find the area

Answers

In this problem, you are asked to find the area of the trapezoid. The formula in finding the area of the trapezoid is:

A = [(a + b)/2] x h

Where a = base 1

b = base 2

h = height

Substituting the given measurements to the formula:

A = [(1.7 m + 6.7 m) / 2] x 5 m

A = (8.4 m / 2) x 5 m

A = 4.2 m x 5 m

A = 21 m^2

Therefore, the area of the trapezoid is 21 square meters.

Your sock drawer has 3 pairs of black socks, 4 pairs of brown socks, 1 pair of yellow socks and 5 pairs of blue socks. you reach into the drawer in the dark and randomly pick out 2 pairs for your business trip. what is the probability your pick out in this order. 2 black pairs?

Answers

All socks together: 13
Black socks: 3

Probability to pick out black socks: 3/13

After one pick out (You picked out a pair of black socks):

Probability to pick out black socks: 2/12

Multiply them:

2/12 * 3/13 = 1/26 ≈ 0,038

The probability your pick out in this order 2 black pairs 1/26.

What is the probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Mathematics to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory.

According to the question,

The sock drawer has 3 pairs of black socks, 4 pairs of brown socks, 1 pair of yellow socks and 5 pairs of blue socks.

All socks together = 3+4+5 = 13

Black socks = 3

Probability to pick out black socks: 3/13

After one pick out (You picked out a pair of black socks),

Probability to pick out black socks: 2/12

Then, the probability = 2/12 × 3/13 = 1/26.

Hence the required probability = 2/12 × 3/13 = 1/26.

Final answer:

This detailed answer covers evaluating functions at specified values, identifying the y-intercept of a function's graph, determining asymptotes, identifying points of maximum growth rate in logistic functions, and intervals where the function's growth rate is decreasing, all critical concepts in understanding mathematical functions in high school.

Explanation:

The questions provided are focused on evaluating specific values of functions, understanding the y-intercept of a graph, determining asymptotes, identifying points of maximum growth rate, and assessing intervals of decreasing growth rate for various exponential and logistic functions. Each of these concepts plays a crucial role in understanding the behaviors and characteristics of different types of mathematical functions, which are fundamental in high school mathematics.

To find f(-3) for the function f(x)=8/(1+3e^{-0.7x}), substitute x=-3 and evaluate.The y-intercept of a graph is found by evaluating the function at x=0.Asymptotes can be determined by evaluating the limits of the function as x approaches infinity or negative infinity.The point of maximum growth rate for a logistic function occurs at the point where the function's second derivative changes sign.The growth rate is decreasing over intervals where the second derivative of the function is negative.

What is the inverse of f(x) = 8x - 7

Answers

y=(x+7)/8

Work:
Y=8x-7 —> x=8y-7
Solve for y
x+7=8y
y=(x+7)/8

Final answer:

The inverse of the function f(x) = 8x - 7 can be found by switching the x and y, then solving for y. This gives the inverse function as f^-1(x) = (x + 7) / 8.

Explanation:

The inverse of a function is calculated by switching the input and output variables. Given your question, we are to find the inverse of the function f(x) = 8x - 7. To do this, we first rename f(x) as y, giving us y = 8x - 7.

Next, we switch the positions of x and y, leading to x = 8y - 7. Then, to isolate y which represents the inverse function, we should solve the equation for y: x + 7 = 8y and y = (x + 7) / 8. So, the inverse of the function f(x) = 8x - 7 is f^-1(x) = (x + 7) / 8.

What is the graph of the function f(x) = the quantity of x plus 4, all over x plus 6?

Answers

I've downloaded a graph for you. It is one of the first things you should always think about with a question like this one. You should notice the following about it:
1. The denominator gives a discontinuity point at (x = - 6). You can tell that is happening just by looking at the graph at x = - 6. The range at that point is - infinity to plus infinity. Other critical points are much better behaved. The y intercept is when x = 0 or 4/6 = 2/3. So the point is (0,2/3)

There is one x intercept at y = 0. When that happens
x + 4 = 0
x = - 4
Point (-4,0)

Notice the whole denominator gets multiplied out. 0 * (x + 6) = 0

An explosion causes debris to rise vertically with an initial velocity of 160 feet per second. What is the speed of debris when the height is 300 feet?

I am using the formula: -16t^2 + vot + h0 because the question is referring to feet.

Answers

The question is asking what v_final is, given that v_initial is at 300 feet. and v_initial is at 0 feet.
We know there will be a constant downward acceleration of 32.15 ft/s^2.
Use the following equation:
v_final^2 = v_initial^2 + 2ah
v_final^2 = (160 ft/s)^2 + 2(-32.15 ft/s^2)(300 ft) = 6310 ft^2/s^2
v_final = (6310 ft^2/s^2)^1/2 = 79.4 ft/s.

The speed of the debris is 79.4 ft/s

Calculation of the speed:

Since there is an initial velocity of 160 feet per second, height is 300feet

So, we applied the below formula

[tex]v_({final})^2 = v_({initial})^2 + 2ah\\\\ v_({fina})l^2 = (160 ft/s)^2 + 2(-32.15 ft/s^2)(300 ft)\\\\ = 6310 ft^2/s^2\\\\ = (6310 ft^2/s^2)^{1/2}\\\\ = 79.4 ft/s.[/tex]

Therefore, The speed of the debris is 79.4 ft/s
