a round swimming pool has a circumference of 66 feet. Carlos wants to buy a rope to put across the diameter of the pool. the rop

xxMikexx [17]

Answer:

$11.25
21 ft

Step-by-step explanation:

The formula for the circumference of a circle in terms of diameter is ...

C = πd

Then the diameter is ...

d = C/π

If we use π ≈ 22/7 and C = 66 ft, then we find the diameter to be ...

d = (66 ft)/(22/7) = (66 ft)(7/22) = 21 ft

The diameter of the pool is about 21 feet.

Since Carlos needs 4 more feet of rope, he will want to buy 25 feet of rope for a cost of ...

(25 ft)($0.45 /ft) = $11.25

Carlos will pay $11.25 for the rope.

It takes Ms. Campbell 5 times as long as it takes Ms. Dorsey to paint a room. If Ms. Dorsey

Aliun [14]

Answer:

Dorsey = 4.8 hours

Campbell = 24 hours

Step-by-step explanation:

It takes "x" hours for Dorsey

So, it will take 5 times more for Campbell, so

It takes "5x" hours for Campbell

Rate is inverse of time, so rates are:

Dorsey: 1/x

Campbell: 1/5x

We know Rate * Time = Work

When together, it takes 4 hours to finish a work, so we can write:

$(\frac{1}{x}+\frac{1}{5x})4=1$

Solving for x, we get the time of Dorsey:

$(\frac{1}{x}+\frac{1}{5x})4=1\\(\frac{1}{x}+\frac{1}{5x})=\frac{1}{4}\\\frac{5+1}{5x}=\frac{1}{4}\\\frac{6}{5x}=\frac{1}{4}\\5x=24\\x=4.8$

Dorsey takes 4.8 hours alone

Campbell takes 4.8 * 5 = 24 hours alone
