Answer:
Step-by-step explanation:
For any prism or cylinder for that matter, you can find the volume by multiplying the area of the base times the height. So this problem just becomes simple algebra.
B * h = V
25 * h = 80
h = 80/25
h = 3.2
If you don't get why it's the area of the base let me know and I can try to explain it.
Answer:
Step-by-step explanation:
z = 180 - (180 - 114.8) - 45.6 = 114.8-45.6 = 69.2°
area = x^2 -10x+25
side = sq root area
x^2-10x+25 = (x-5)(x-5) = (x-5)^2
=》 side = (x-5)
Answer:
Pentagon, convex
Step-by-step explanation:
All of the interior angles are less than 180. Hope this helps.
Answer:
Step-by-step explanation:
x + y = 27
We know that there are 5 less girls that boys, so:
x + (x-5) = 27
x + x - 5 = 27
Solve for x:
2x - 5 = 27
2x = 32
x = 16 boys
y = 11 girls
