Answer:
-4
Step-by-step explanation:
Parallel lines have the same slope so we know that m = -4.
The volume of a hemisphere is 2/3 pi R^3.
1) 2/3 x 3.14 x 10^3
2)2/3 x 3.14 x 1000
3)2/3 x 3140
4) 2093.3
Let x be the score of the 3rd quiz,, then the average score will be:
(83+91+x)/3, which = (174+x)/3. but this average should be greater or equal to 85 and smaller or equal to 90:
85 ≤ (174+x)/3 ≤ 90
1st multiply all terms with 3 → 255 ≤(174+x) ≤ 270
2nd subtract 173 from all terms → 255-174 ≤174-174+x ≤270-174
81 ≤ x ≤ 96
