A right rectangular prism is packed with cubes of side length 1 over 2 inches. If the prism is packed with 5 cubes along the len

Dmitry [639]

Answer:

<em>Answer: C.Fraction 11 and 1 over 4 cubic inches</em>

Step-by-step explanation:

The volume of a rectangular prism of length L, width W, and height H is given by:

V=LWH

The prism is packed with cubes of a side length of a=1/2 inch. The volume of each cube is:

$V_c=a^3=\left(\frac{1}{2}\right)^3=\frac{1}{8}\ in^3$

The prism is packed with L=5, W=3, and H=6, thus the volume (in cubes) is:

V=5*3*6=90\ cubes

Since each cube has a volume of $\frac{1}{8} in^3$ :

$V=90\cdot\frac{1}{8}=\frac{45}{4}$

Expressing as a mixed fraction:

$V=\frac{45}{4}=\frac{44+1}{4}=11\frac{1}{4}$

Answer: C.Fraction 11 and 1 over 4 cubic inches

Hi.

First, I am going to give you some definitions.This will help you do the problems.

-Complementary angles have a combined sum of 90.

- Supplementary angles have a combined sum of 180.

10. 40+50=90- so YES.

12. 159+20= 179.-so NO.

Make sure you learn the definitions properly next time!

What is the inverse function of f(x) = 25x-3?

Harrizon [31]

Answer:

The answer is

Step-by-step explanation:

$f(x) = 25x - 3$

To find the inverse of f(x) , equate f(x) to y

That's

y = f(x)

We have

$y = 25x - 3$

Next interchange the terms that's x becomes y and y becomes x

$x = 25y - 3$

<u>Next solve for y</u>

Move 3 to the other side of the equation

That's

$25y = x + 3$

<u>Divide both sides by 25</u>

$\frac{25y}{25} = \frac{x + 3}{25}$

We have the final answer as

${f}^{ - 1} (x) = \frac{x +3 }{25}$

Hope this helps you
