Answer:
101 revolutions
Step-by-step explanation:
Given: The diameter of the bike wheel is 19 inches.
We need to find the circumference of the wheel.
The circumference of the wheel = πd
π = 3.14 and d = 19
Now plug in these values in the above formula, we get
The circumference of the wheel = 3.14*19
= 59.66 inches
We need to find number of revolutions of wheel to cover the distance of 500 feet.
Now we have to convert 500 feet to inches.
1 foot = 12 inches.
500 feet = 500 *12 = 6000 inches.
The number of revolution = 6000 / 59.66
= 100.56
When we round of to the nearest whole number, we get 101
To cover the distance of 500 feet, the wheel must be rotate 101 times.
I think it was √(a^2+b^2. I think.

Answer:
Step-by-step explanation:
9^(1/2) =3
this expression is : 3(r^(5/2) ×r^(-1) )(t×t^(1/2))
3r^(5/2 - 1)×t^(1+1/2)
3^(1/2)×t^(3/2)...... answer : 2
Answer : 2880.68274 miles/hour
1 foot = 0.000189394 miles
4225 feet = 0.000189394* 4225 miles
distance traveled in 1 second = 0.000189394* 4225 miles
distance traveled in 1/3600 hours = 0.000189394* 4225 miles
distance traveled in 1 hour = 0.000189394* 4225 * 3600 miles
Speed is = 2880.68274 miles/hour
