Answer:
D.
Step-by-step explanation:
The original antenna revolves at a rate of 30 per 2 minutes, or 15 per minute.
Twice as fast = 15 X 2 = 30 per minute
Only the data in Table D fits.
660 / 22 = 30
720 / 24 = 30

Step-by-step explanation:
<u>Average Value</u>
The mean or average of a sample is a number that represents the whole set by the center value of them. The formula to compute the average is

Where xi is the value of the element i and n is the number of elements in the set
We need to find an estimate of how many grapefruits Lily purchased knowing the heaviest and the lightest weight of the set. We can find the average value by using the two extreme values:

If each grapefruit weighed 1.5 pounds, then we can estimate the 22.17 pounds of them will contain

Answer:
no solution
Step-by-step explanation:
3(x+5) +2x=10x-5(x+1)
Distribute
3x+15 +2x = 10x-5x-5
Combine like terms
5x+15 = 5x -5
Subtract 5x from each side
5x-5x+15 = 5x-5x-5
15 = -5
This is never true so there is no solution
12 - 3b < 9
12 (-12) - 3b < 9 (-12)
-3b < -3
-3b/-3 < -3/-3
(note when dividing a negative number, flip the inequality sign)
b > 1 is your answer
hope this helps
