80*4=320
89*4=356
This is the range of the addition of all 4 scores.
99+80+70=249
320-249= 71
356-249= 107
[71, 100] would be the answer, unless you can get extra credit on the final.
<span>No because a negative times a negative will be positive and it will not equal a negative number. the square root cannot be one negative and one positive because that is against the definition of a square root.

Given the sequence {-3, 6, -12, 24, ... }, we can see that the first term (a) is -3 and the ratio (r) is .
Input those values into the Sum formula:
Answer:
A.
Step-by-step explanation:
The formula for circumference is:
We know that the circumference is 8π inches. So, substitute 8π for C:
Solve for r. Divide both sides by 2π. So:
Therefore, the radius is 4 inches.
Hence, our answer is A.
