Answer:
$350
Step-by-step explanation:
y · 5 = 250 · 7
5y = 1750
5y ÷ 5 = 1750 ÷ 5
y = 350
<h2>Scalene is the correct answer</h2><h2></h2><h3>(Assuming you mean side lengths when you say 3, 8, 12.)</h3><h3></h3><h3><em>Please let me know if I am wrong.</em></h3>
All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3

The diameter of the cylinder (d) is the twice of its radius (r): d = 2r
The volume (V) of the cylinder with radius r and height h is:
V = π r² h
We have:
d = 2r
r = ?
h = 7
π = 3.14
V = 175π
175π = π * r² * 7
175 = r² * 7
r² = 175/7
r² = 25
r = √25
r = 5
d = 2r
d = 2 * 5
d = 10
