Answer: Correct answer is not listed, is there an option for D? Or was the question worded wrong?
The correct answer to the question you asked would be $716.50
Step-by-step explanation:
17 hours × $24.50 = $416.50
But it says she usually earns $300, and this month she worked 17 extra hours.
So to me, that sounds like you would add her usual earnings to her extra earnings to get the total for the month.
$300 + $416.50 = $716.50
However, if there is not an option for this amount, then the question was just worded a little off and the next best answer would be $416.50 which is the amount of extra income she made while working those extra 17 hours.
Answer:
y=-3x-13
Step-by-step explanation:
Plug in the -2 and -4 for the y and x. The slope is the same
1) -4 = -3 (-3)+b
2) -4=9+b
3) -4-9=b
4) -13=b
The equation is y=-3x-13
Answer:
C. The ratio of the area to the circumference is equal to half the radius.
Step-by-step explanation:
The area of a circle can be written as;
Area A = πr^2
The circumference of a circle is;
Circumference C = 2πr
Using the formula, w can derive the relationship between the two variables.
A = kC
k = A/C
Substituting the two formulas;
k = (πr^2)/(2πr) = r/2
So,
A = (r/2)C
A/C = r/2
The ratio of the area to the circumference is equal to half the radius.
Given;
Area = 200.96
Circumference = 50.24
Radius = 8
To confirm;
k = r/2 = 8/2 = 4
Also,
A/C = 200.96/50.24
A/C = 4
Answer:
≈9.64 gallons
Step-by-step explanation:
To solve, we can figure out how many quarts are in a minute and use that to figure out how many quarts are in an hour. Then, we can convert quarts to gallons.
4.5 quarts = 7 minutes
First, we can find how many quarts equal 1 minute. To do this, we can divide both sides by 7 because anything divided by itself equals 1
4.5/7 quarts = 1 minute
Next, we want to figure out how many quarts go into 60 minutes, or 1 hour. To do this, we can multiply both sides by 60 because 1 * 60 = 60
4.5 * 60 / 7 quarts = 60 minutes = 1 hour
We now know how many quarts are in an hour, so we can now convert quarts to gallons
4 quarts = 1 gallon
divide both sides by 4
1 quart = 1/4 gallons
To get from quarts to gallons, we can divide by 4, so we have
(4.5 * 60 / 7)/4 = 4.5 * 60 / 28
≈9.64 gallons
