Answer:a)EF congruent to QR
Step-by-step explanation:
Check the picture below.
that means
angle AFB is 27 + 2 = 29
angle BFC is 2(27) + 12 = 66
and angle CFD is 2(27) or 54
so hmmmm, you'd know which one isn't there.
The relationship is proportional because it is in standard form
Answer:
The average rate of change from 7 to 60 minutes is 0.36 miles per minute.
Step-by-step explanation:
at x₁ = 7, f(x₁) = 8
at x₂ = 60, f(x₂) = 27
Using the formula to determine the average rate of change at which the total cost increases will be:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [27 - 8] / [60-7]
= 19 / 53
= 0.36
Therefore, the average rate of change from 7 to 60 minutes is 0.36 miles per minute.
Given:
Principal value = $1200
Rate of interest = 3% per year
To find:
The interest earned by Jenny in one year.
Solution:
Formula of interest:

Where, P is principal, r is rate of interest and t is time.
We have, P = 1200, r = 3, t=1. Putting these values, we get



The interest earned by Jenny in one year is $36.
Therefore, the correct option is A.
