Answers
Answer:
A) 60 Degrees
B) 550 Feet
C) 2.5 minutes
Step-by-step explanation:
a) So the wheel has completed one revolution in 10 minutes so lets first divide 100 secs with 10 minutes to calculate the the fraction of revolution
1 min = 60 secs
10 min = 600 secs
100/600 = 1/6
One complete revolution is 360 degrees and 1/6 of 360 degrees will be 60 degrees .
360/6 = 60°
b) It takes 10 minutes to complete one revolution so if the person is on it for 7 minutes it would be 7/10 of a revolution . The ferris wheel has a diameter of 250 feet so the radius will be 125 feet because it is the half of the diameter and the circumference will be 250 π . To calculate the distance lets multiple the fraction of the revolution which is 7/10 into the circumference = 550 Feet.
C)It took 10 minutes to travel 250 π now we will use this relation to calculate 200 feet . lets suppose t is for time .
.
After solving this equation as there is only one unknown which is "t "the answer will be 2.5 minutes.

Answer:
So we know 4 inches is 120 yds
Step-by-step explanation:
We can use ratio's to solve this problem
1 inch 4 inch
------------ = --------------
30 yds x yds
Using cross products
1 * x = 30*4
x = 120
So we know 4 inches is 120 yds
Answer:
120 yards
Step-by-step explanation:
A map scale is a ratio.
1 inch : 30 yards
Multiply both sides of the ratio by 4.
4 * 1 inch : 4 * 30 yards
4 inches : 120 yards
