Answer: Your average monthly interest rate is0.18/12 = 0.015. So your average monthly interest is0.015×$850 = $12.75. Then the annual interest payments would be 12×$12.75 = $153
Answer:
A. 24 lap/hour.
B. r = 24h
Step-by-step explanation:
Let r be the number laps.
Let h be the time.
From the question given above, the number of laps (r) Jessica runs around the track is proportional to the time (h) she spend running. This can be written as:
r & h
r = Kh
Where:
r is the number of laps.
K is the constant of proportionality.
h is the time.
A. Determination of the constant of proportionality.
With the above formula, we can calculate the value of the constant of proportionality, K as follow:
Number of laps (r) = 12 laps
Time (h) = ½ hour
Constant of proportionality (K) =.?
r = Kh
12 = K × ½
12 = K/2
Cross multiply
K = 12 × 2
K = 24 lap/hour
Therefore, constant of proportionality is
24 lap/hour.
B. Equation for relationship between the number of lap and time. This is illustrated below:
r = Kh
K = 24
r = 24h
Therefore, the equation for relationship between the number of lap and time is r = 24h

F(x)= x² + 8
When x = 10
f(x) = 10² + 8 = 108
Answer: 108
Answer:
3
Step-by-step explanation:
When both sides in the pre-image are multiplied by 3, you get the image. and since it is getting bigger and not smaller, it would be a whole number aka 3.
