The blades on a wind turbine trace a circular path with radius 100 feet. suppose the turbine spins at 20 revolutions per minute. what is the linear velocity, in miles per hour (1 mile equals 5,280 feet), of a point on the tip of a blade? round the answer to the nearest tenth.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

it is true
