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
.6% will be a decimal because when u move u only had to move two time to the right side
Answer:
The answer is :
Step-by-step explanation:
Given that the slope-intercept form is represented by y = mx + b. So you have to rearrange the equation :
Find slope: (y2-y1)/(x2-x1)
(3-4)/(-1-2) = -1/-3 = 1/3
Y = 1/3x + b
4 = 1/3(2) + b
4 = 2/3 + b, b = 10/3
Y = 1/3x + 10/3
