The person is traveling 30 mph.
The car is traveling 45 mph.
Just mulitply 15 x 3 and 10 x 3.
Let’s break the numbers down.
10 + 5 = 15. So we can break 15 down like how you add 15.
10 x 3 = 30.
5 x 3 = 15.
Let’s add 30 and 15 together.
30 + 15 = 45.
Let’s now multiply 10 and 3.
10 x 3 = 30.
I hope this helped!
For this case, we have by definition, that an irrational number is a number that can not be expressed as a fraction
, where a and b are integers and b is nonzero.
Some examples are:

So, that the answer is 
Answer:
Option C
Answer:
730
Step-by-step explanation:
A(X)= 2πRH+2πR^2
A(X)=2π(7.5)(8)+2π(7.5)^2=730.42 = 730
(the answer is) = 6466602
Answer: x = 4; x = 5
Step-by-step explanation:
The directions specify to solve by factoring
x^2 - 9x + 20 = 0
To factor, find two numbers that add to -9 and multiply to 20
-5 and -4 work
-5 + (-4) = -9
-5 * -4 = 20
(x - 4)(x - 5) = 0
x = 4, x =5
