Answer:
C. She makes $127.50 a week
Step-by-step explanation:
Since we are looking for how much she makes every week, we need to multiply her number of hours by the pay. She makes 8.50 per hour and works 15 hours.
8.5x15=127.5
She makes $127.50 a week
Answer:
43.75 mph
Step-by-step explanation:
Divide 75 by 4 and divide 4 by 4 which gets the unit rate
Answer:2.5
Step-by-step explanation:
5 is a odd number which means it's a little harder to divide but when you do, you get 2.5

5.0 = 5
Step-by-step explanation:
V = $12
M = The number of months
So, function = v + $2m
Lets take an Example = for example the stock price now is $20
V + $2m = $20
V = $12
So, 12 + $2m = 20
$2m = 20 - 12
$2m = 8
m = 8/2
m = 4
So this used we can easily find the number of months
Now let's try with the stock price only
The total now is $24
And 6 months passed
v + $2m = $24
v + $2(6) = $24
v + $12 = $24
v = $24 - $12
v = $12
So we got the same stock price
We found with this function the stock price as well as the number of months
Hope this answers ur question!
Circumference of a white oak tree:
C = 90 in.
C = 2 r π
2 r π = 90
r · 6.28 = 90
r = 90 : 6.28
r = 14.33 in ( but it is not r in the formula )
Since the bark is 0.5 in thick: r = 14.33 - 0.5 = 13.83 in
a = r : w = 13.83 : 0.2 = 69.15 years
The widest ring is one that shows 69 years:
r = 69 · 0.2 = 13.8 in
A = r² π = 13.8² · 3.14 = 190.44 · 3.14 = 597.98 in²
Answer: The tree`s age is 69.15 years ( or 69 years and 2 months ) and the area enclosed by the outer circumference of the widest ring is 597.98 in².
