Answer:
6 hours
Step-by-step explanation:
A: y=125+7x
B: y=110+10x
for A to be a better deal than B, 125+7x<110+10x has to be true
- subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3x
- divide by 3: 5<x
- so x has to be greater than 5, im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you
.no lo sé, pero como necesito puntos, ¿sí?
Assuming the cylinder is closed at both ends
Surface area = 2 pi r^2 + 2 pi r h = 108
now h = r/2 so we have:-
2pi r^2 + pi r^2= 108
3 pi r^2 = 108
r^2 = 11.459
r = 3.385
so the height h = 1.693 m to nearest thousandth
