Answer:

1440ft^3

Step-by-step explanation:

Volume of a rectangular prism = Length* width * Height

Given

width = 8ft

Length = 20ft

height = 108in

Convert 108 inches to feet

1ft = 12in

x = 108in

x = 108/12

x = 9ft

Get the volume of the prism

Volume = 8 * 20 * 9

Volume = 1440ft^3

Hence the volume of toilet paper it can deliver is 1440ft^3

What is the value of x and y if 21x+7y=42 and -5x+5y=10 are equal

nikdorinn [45]

Answer:

-5x/5 +5y/5=10/5=2

y-x=2

y=x+2

21x+7*(x+2)=42

21x+7x+14=42

28x=42-14

28x=28

x=1

y=1+2

y=3

3/4 of a cake is left and is divided equally among four people. How much of the remaining cake does each person get?

Naily [24]

Answer:

each person can get 3/12 if you split the 3.4 twice.

Step-by-step explanation:

make a circle

split one line down the middle and the other horizontal.

color is one of the corners. you will not use it. this is the part of the cake they already ate.

now you have three remaining parts.

split each one of the remaining heart down the middle.

now you have six remaining slices.

6 is not divisible by 4.

split the sixths down the middle one more time.

now you should have 12.

12 is divisable by 4.

give each person 3 out of 12 slices of cake.

it is just enough to feed all 4 people.

The question is: "Without actually graphing, describe how the graph of y = ( -2^(x+17) ) - 4.3 is related to the graph of y = 2^

Leokris [45]

Answer:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

Step-by-step explanation:

When functions are transformed there are a few simple rules:

Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
Multiplying the function by a number less than 1 compresses it towards the x-axis.
Multiplying the function by a number greater than 1 stretches it away from the x-axis.
Multiplying by a negative flips the graph.

The graph of $(-2^{x+17}) -4.3$ compares to $2^x$ in the following ways:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.
