5 with an exponent of 9 is 45
Answer:
B. 60
Step-by-step explanation:
There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.
15% got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds
The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds
Answer:
Step-by-step explanation:
Remark
√80 = √(16 * 5) = 4√5 I will put the - sign in when I gather terms
√45 = √(9 * 5) = 3√5
Expression
4√5x - √80x+√45x
Solution
4√5x - 4√5x + 3√5x
The first two terms cancel out
3√5x is all that is left
Answer: 3√5x

notice, if the "r" and "h" is the same for both, the cone's volume is just 1/3 of the cylinder's
I believe it’s. D it seems most reasonable
