Answer:

558 cm^3

Step-by-step explanation:

V cone = 1/3 pi r^2 h

186 =1/3 pi r^2 h

Multiply by 3

558 = pi r^2 h


V cylinder = pi r^2 h

baherus [9]

Answer:

The reason Carlos chose A as the correct answer is because by the way 4,325,000,000 is set up in standard form he would have it set back to 4.325 x 10^-9 instead of 4.325 x 10^9

Find how many quarts of 6% butterfat milk and 1% butterfat milk should be mixed to yield 75 quarts of 3% butterfat milk.
Strike441 [17]

Answer:

30 gallons of 6% milk, and 45 gallons of 1% milk.

x=quarts of 6% butterfat

First, write an equation.

0.06x+0.01(75-x)=0.03*75

Multiply both sides by 100.

0.06x*100+0.01*100(75-x)=100*0.03*75

Simplify

6x+75-x=3*75

6x+75-x=225

Solve

5x=225-75=150

5x=150

x=30

75-30=45

So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.

Kalvin tosses a paper cup once a day for a year to determine his breakfast cereal. 85% of the time the cup will land on its side
Vlad [161]

Answer:

the cup will land on its side 310 times and it'll land on the end 55 times

Step-by-step explanation:

To determine the amount of times it lands on the side, take the days in a year, 365, and multiply that by .85, which gets you 310. To get the amount of times it lands on its end, just subtract 310 from 365.
