Answer:
477.47 revolutions
Step-by-step explanation:
From the information given:
The formula for calculating the circumference = 2π r
Given that the radius of each wheel = 25 centimeter
Then, the circumference = 2 π (25)
= 50π cm
The distance traveled in 5 minutes is as follows:
Given that:
The speed = 45 km/ hour
i.e.
1 hour = 45 km
In an hour, we have 60 minutes
So, 60 minutes = 45 km
1 minute = 45/60 = 0.75 km
To cm;
0.75 km = (0.75 × 1000) m = 750 m
750 m = 750 × 100 = 75,000 cm
∴
The number of revolution in 5 minutes sInce 1 revolution = 50π cm is:
= 75,000 cm/ 50π cm
= 477.47 revolutions in 5 minutes

Step-by-step explanation:
Problem: -3/8(x-24)+x=19
Distribution:
-3/8x + 9 + x = 19
5/8x = 19 - 9
5/8x = 10
x = 10 • 8/5
x = 16
Formula for area of triangle is Base times height divided by 2 equals Area
Or
B×H÷2=Area so it would be
15.25×18=274.5
Divided by 2 =137.25 inches
