Daniel is blowing up a beach ball in the shape of a sphere. The package says that the ball has a diameter of 9 inches. Which measurement is closest to the volume of the beach ball when it is completely filled with air?

A. 84.8 cubic inches

B. 381.7 cubic inches

C. 972 cubic inches

D. 3,053.6 cubic inches

Answers

Answer 1

Answer:

B. 381.7

Step-by-step explanation:

because the diameter is 9 we know the radius is 4.5 (radius is half of the diameter)

the formula for volume: V= 4/3πr^3

V=4/3•π•4.5^3

that equals approx. 381.7

Tangent this equation: [tex]63(b-1)+7=7(9b-8)[/tex]

Answers

Answer: True for all b.

Step-by-step explanation: To tangent a equation, find if the variable is true.

1. Add 56 to both sides.

63b - 56 + 56 = 63b - 56 + 56 = 7

2. Simplify.

63b = 63b

3. Simplify again for your answer.

0 = 0

Hence, both sides are equal.

taxi cab charged $3.60 for all rides and $2.20 per mile. If Tommy’s cab ride cost $43.20, how many miles did he travel?

Answers

Answer: 18 miles

Step-by-step explanation: Cabs drivers fee is 3.60 for all rides so you subtract that from 43.20 and you get 39.60 and divide that by the amount he costs per mile and you get 39.60 divided by 2.20 and get 18.

Answer:

Tommy travels 18 miles in total

Step-by-step Explanation:

43.20 - IV (IV = Initial value)

43.20 - 3.60 = 39.6

39.6/ROC (ROC = Rate of Change)

39.6/2.2 = 18

Tommy traveled 18 miles.
