Answer:
10+4h
Step-by-step explanation:
variation
the constant $10+the variable( 4×hpw many hours used).will give me that answer.
Using the mean concept, the expression that gives the average of the low and high temperatures is:
(-3 + 8)/2.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the two observations are -3 and 8, hence their average is given by:
(-3 + 8)/2.

Answer:
b
Step-by-step explanation:
The area of a square = s² ← s is the length of the side, hence
s² = 800 ( take the square root of both sides )
s = 
≈ 28.28
28.28 is between 28 and 29 → b
511/8-243/4
511/8-486/8=25/8
Answer:
12 pounds
Explanation:
If you were to divide 12.24 from 12 you would get 1.02, which would be the cost of each pound.
Meanwhile, if you were to divide 8.24 from 8 you would get 1.03, which would be the cost of each pound.
So although its only a 1 cent difference and you are technically spending more by buying the 12 pounds, if it were to buy 8 pounds from the cost of each pound for the 12 pounds, you'd only be spending $8.16 vs $8.24.
Because you would multiply 1.02, which is the cost of each pound for 12, by 8 and you would get 8.16.
