Answer:

8 ft

Step-by-step explanation:

The area (A) of a triangle = $\frac{1}{2}$ bh

where b is the base and h the perpendicular height

Using b = 20 and h = 12, then

A = 0.5 × 20 × 12 = 120 ft²

Using b = 30 and perpendicular height = h, then

0.5 × 30 × h = 120

15h = 120 ( divide both sides by 15

h = 8

1.) Gather all the sides (length, width, and height)
V=l×w×h

2.)Plug in the correct and appropriate volume:
V=8×6× $\frac{1}{3}$

3.)Multiply all of them:
V=8×6× $\frac{1}{3}$
=48× $\frac{1}{3}$
= $\frac{48}{3}$
=16 (after simplifying)

4.) State the answer in a sentence:<span>

The volume of the rectangular prism is 16 </span> $cubic^{2}$ .

Hope this helps!

4/5 of the original amount at the start of the month will remain. The amount at the start of every month will change. Thus:
an = 4/5 (an-1) ; where a1 = 500.

3) For what price is 15 percent off the same as $75 off?

Kryger [21]

$\text{In this question, you would need to find the right value that 15\% is \$75}\\\\\text{You can do this by multiplying each number by 0.15}:\\\\200*0.15=30\\\\300*0.15=45\\\\350*0.15= 52.5\\\\500*0.15=75\\\\\text{You would see that 15\% of 500 is \$75}\\\\\boxed{\$500}$
