AD BC are parallel because the lines are equal
If Caitlin is...
A. 3 years old, the difference between her and Caitlin would be 9 years. That times 3 is 27. Not Amanda's age.
B. 12 - 5 = 7 (difference) 7 * 3 = 21 is not Amanda's age.
C. 12 - 7 = 5 5 * 3 = 15 = Amanda's age!
Correct answer is C
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:
Step-by-step explanation:
If you are asking what 3x2-48 is, then the rules of Pemdas would be relevant in this.
First we would multiply. So, 3 times 2 is 6.
Then, 6-48 is -42
