Regina spent $45.50 over 612 months on music downloads.
If she spent the same amount of money each month, how much money did Regina spend per month on music downloads?
Answers
Answer:
.07 cents
Step-by-step explanation:
In order to solve this question all you need to do is divide the money spent by the amount of months. 45.50/612=0.0743464052 but since you cant spend .0043464052 of a cent we have to change the answer to .07. To check our answer is right all we need to do is multiply 0.0743464052 by 612=45.499999 so we know the answer is correct.

Answer:57
Step-by-step explanation:
Answer:
B) 0.57
Step-by-step explanation:
It says "given that you are in Sacramento", so hint: only look at the Sacramento row. Ignore everything else, you don't need it.
Then it asks what is the probability of a clear day, so you look at the "Clear" column from the Sacramento row. That would be 17 days.
Lastly, you just simply divide from the total days. 17/30 = 0.57

lisa drank 1/3 quart of orange juice and lane drank 1/2 quart of orange juice. how many quarts did they drink together
Answers
Answer:
[tex]\frac{5}{6}[/tex] quarts
Step-by-step explanation:
Total amount of drinks = [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{2}[/tex]
You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.
[tex]\frac{1}{3}[/tex] + [tex]\frac{1}{2}[/tex] = [tex]\frac{2}{6}[/tex] + [tex]\frac{3}{6}[/tex]
Now we can directly add them together while keeping the denominator the same.
[tex]\frac{2}{6}[/tex] + [tex]\frac{3}{6}[/tex] = [tex]\frac{5}{6}[/tex] quarts
The variables x and y very directly. Use the values to find the constant of proportionality K then write equation that relates to x and y. Write any fraction in simplest form. Y equals 20 and X equals 12
Answers
Answer:
k=5/3
Step-by-step explanation:
The variables x and y vary directly. Given that, y = 20 and x = 12
We can write it as :
y=kx
Where k is constant of proportionality
Put the values of x and y
20=12k
k = 20/12
k = 5/3
So, the value of the constant of proportionality is 5/3.

The standard form of the given expression is 7x - y = 17
Equation of a line in standard formThe equation of line in standard form is expressed as Ax + By = C
Given the equation
y + 3 = 7(x - 2)
Expand
y + 3 = 7x - 14
y -7x = -14 - 3
-7x + y = - 17
7x - y = 17
Hence the standard form of the given expression is 7x - y = 17

URGENT ! what is the common difference of the arithmetic series 14+12+10+8
Answers
Explanation:
An arithmetic sequence has a common difference, meaning you use addition or subtraction to get from term to term, and each term in the sequence is an equal distance apart.
A geometric sequence has a common ratio, meaning that you use multiplication or division to get from term to term.
If you look at this sequence:
14-2 = 12
12-2 = 10
10-2 = 8
8 -2 = 4
etc.
Because you are subtracting 2 each time, 2 is the common difference, and the sequence is arithmetic.
