It would be take upto 999 revolutions.
<em>Let try to solve it,</em>
Let n represent number of revolutions.
We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.
1 mile = 63360 inches.
We will use circumference of circle formula to solve our given problem.
Circumference = pi*d , where, D represents diameter of circle.
Now, we will set the product of n and circumference of circle equal to 63360 inches as:
pi*22*n= 63360
n= 63360*7/ 22*22
n= 443520/444
n= 998.91
Therefore It would be take upto 999 revolutions.

Answer:
- $50 + $200 - $800
Step-by-step explanation:
You have to pay $50
This is a negative to your account: -$50
You win $200
This is a positive to your account: + $200
After you have to pay $800
This is a negative to your account: - $800
Total transaction
- $50 + $200 - $800
The expression that represent the situation is:
- $50 + $200 - $800
= - $650
Answer:
0
y = 2
Step-by-step explanation:
Since it's a flat line, the slope is 0.
Since all of the points have a y-value of 2, the equation is y = 2.
First step: (simplify) y+9+7y+63, Second step: (combine) 8y+72
