Answer:
$13,177.97
Step-by-step explanation:
Compound Interest Formula

A = final amount
P = initial investment
r = interest rate
n = number of times the rate is applied during a time period
t = number of times the time period has elapsed

Think of sqrt(2) as a variable.
3x - x = 2x
If x = sqrt(2), then answer is 2sqrt(2)
Let n = minutes since 12:00 pm when Malory catches up to Dori.
Dori travels
(50 steps/min)*(n minutes) = 50n steps
Malory begins walking at 12:20 pm, so she walks for (n - 20) minutes. She travels
(90 steps/min)*(n - 20 min) = 90n - 1800 steps
Equate the steps traveled by Dori and Malory.
90n - 1800 = 50n
40n = 1800
n = 45 min
The time corresponding to n = 45 min is 12:45 pm
Answer: 12:45 pm
the diagonal of a rectangle is square root of (w^2 +l^2)
so square root of (14^2 +10^2) = 17.2 inches
since 20" is longer than 17.2 it can't be a rectangle
Well since we already have our unit per mile.
We know that 1 mile = $3.50
And that the tow company towed the car 12 miles.
So we would have to multiply 12 by $3.50
soo..
12 x $3.50 = $42.00
So your answer is D. $42.00
