Answer:
3/5 , 0.6, 60%
3/4 , 0.75, 75%
4/5 , 0.80, 80%
9/10 , 0.9, 90%
and the last one should be 2/2 , 1. , 100%
X=14
y=3x^2+17
y=3(14)^2+17
y=3•196+17
y=588+17
y=605
Well, you don't have any options.
But a mixed number for 12.16 would be 12 4/25. Hope it helps! :)
Answer:
80°
Step-by-step explanation:
Since they are vertical angles, they are congruent to each other.
∠r ≅ 80°
<em>V = 120 in^3</em>
<u><em>Here is why:</em></u>
The volume formula for a pyramid is:

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.
The area formula for a triangle is:

Plug in the numbers.

A = 45
Now we have found the area of B, we can plug it into the volume formula for the pyramid.

V = 120 in^3
