Hi!

<h3>Let's set up a proportion and cross multiply. </h3>

\frac{20}{25}\frac{x}{100}

<h3>solve for x</h3>

20 * 100 = 2000

<u>2000/25 = 80</u>

<h2>The answer is 80%</h2>

Hope this helps! :)

A rectangular prism measures 225 inches by 315 inches by 2 inch.
Bas_tet [7]

Answer:

No I don't agree with Priya

The reason why I don't agree with Priya is because 25 Inch side blocks are BIGGER than 15 inch side blocks. That means that it will take less amount of 25 inch side blocks to fill up the volume of the rectangular prism rather than 15 inch side blocks.

(I'm sorry, I don't know what was your previous question, so I can't answer that part. If you comment it below, I will do it!)

If f(x) = 1/2x-14,then f^-1(x)=
Alik [6]

Answer:

f ^-1 (x) = 2x+28

Step-by-step explanation:

f(x) = 1/2x-14

Replace f(x) with y

y = 1/2 x -14

Exchange x and y

x = 1/2 y -14

Solve for y

Add 14 to each side

x+14 = 1/2 y -14+14

x+14 = 1/2 y

Multiply each side by 2

2(x+14)= 1/2 y*2

2x+28 = y

The inverse function is

f ^-1 (x) = 2x+28

If: AB= 2x + 6, AC = 51, and BC=6x +5, Find BC.
Marina86 [1]

Answer:

<h3>Assuming A, B, and C are collinear and B is between A and C then BC = 35 </h3>

Step-by-step explanation:

Assuming A, B, and C are collinear and B is beetween A and C

AB + BC  = AC

2x + 6 + 6x + 5 = 51

 8x + 11 = 51

    8x = 40

     x = 5

BC = 6x+5 = 6×5 + 5 = 35
