If you find the volume of each figure separately then add them together, then you'd get your answer.

The formula for volume is V=Base Area*Height, V=BH
So the volume of the smaller cube is 210.
This is because the base area is 15*14. Multiply this by the height, 16, then you get 210.

The volume of the second cube is 25,100. This is because 15+16 is 31. 31*27*30 is 25,100.

If you add both of these volumes together, you're final answer is 25,310 units cubed.

Hope this helped :)

You are purchasing books summer reading for $4.50 each. Part A: Your total cost, C, depends on,The input is,and the output is,Pa
Crazy boy [7]

Answer:

Part A) see the explanation

Part B) C(12)=\$54

Step-by-step explanation:

Part A)

we know that

A relationship between two variables, x, and C, represent a proportional variation if it can be expressed in the form k=\frac{C}{x} or C=kx

Let

C ---> is the total cost (represent the output or dependent variable)

x ----> is the number of books (represent the input or independent variable)

In this problem

we have a proportional relationship between the variables x and C

Part B)  we know that

The linear equation is given by

C=kx

The constant of proportionality k is the same that the slope or unit rate of the linear equation

In this problem the constant k is given

k=\$4.50\ per\ book

so

C=4.50x

For x=12 books

substitute in the equation and solve for C

C=4.50(12)=\$54

In function notation

C(12)=\$54

Find the angle x (in degrees) that the wheelchair ramp makes with the ground.​
iogann1982 [59]

Answer:

x=175

Step-by-step explanation:

The sum of all the degrees in a triangle is 180. First, you have to rind what the third degree of the triangle is. We will call this y.

85+90+y=180

175+y=180

y=5

The floor is flat, so it will be 180 degrees, therefore, x+y=180. We can substitute 5 in for y, so 5+x=180.

So, x would be 175.

Jessica wants to plan where she will place furniture in her room, so she has drawn a scale model of her room in order to begin p
Setler79 [48]
To solve this problem you must apply the proccedure shown below:
 1. You have that:
<span> - The scale model is 11 inches long and 8.5 inches wide.
 - The door to her room takes up 1.75 inches.
 - The longest wall in Jessica’s actual room is 15 feet long.
 2. Therefore, the actual size of the door is:
 15 feet=180 inches
 1.75 inches(180 inches/11 inches)=28.63 inches
 3. If the door in completely open, you must apply the formula for calculate the area of a semicircle:
 A=</span>πr²/2
 r=28.63 inches
 A=π(28.63 inches)²/2
 A=1288.11 inches²
 The answer is: 1288.11 inches²
