If the radius is 5 ft, the circumference is 10 pi or about 31.4

1000 divided by 31.4 = 31.8

So, it should make a minimum of 32 revolutions to reach 1000 feet.

How did the tempicher change if at first it increased by 5% and then increased by 20 percent
tensa zangetsu [6.8K]

Answer:

Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.

Step-by-step explanation:

Take a number, x.

Now increase it by 5%.

1.05x

Now increase it by 20%.

1.2 * 1.05x = 1.26x

1.26x = 126% of x = 100% of x + 26% of x

100% of x is the same as x, so it is the same as the original x.

The increase is 26% of the original number.

Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.

Blake bought a total of 24
Harman [31]
5/8 = 0.625 = 62.5%

If 62.5% were glazed then you must find 62.5% of 24.

Equation…

x=0.625(24) = 15

if each costs $0.84 cents plus tax then you will multiply by 15.

15 x .84 = 12.6

The total cost was $12.60
