Well let’s find the actually mean
First we add up all the numbers
87+46+90+78+89 = 390
Next we divide 390 by how many numbers there are.
390/5 = 78
Therefore the mean is 78

Answer:
C. parallel lines
Explanation:
If two straight lines be at right angles to the same plane, the straight lines would be parallel.
The answer to your question is 4x^2 - 16
Hope this helped
Answer:
It takes Katie 66 2/3 seconds to run 400m. Min conversion: 1 min and 6 2/3 secs
Step-by-step explanation:
(6 1/3) / (5/6) = (19/3) / (5/6) = 19/3 * 6/5 = 114/15 = 38/5
3 - 7^2 + 3 * 4^2
3 - 49 + 3 * 16
3 - 49 + 48
- 46 + 48

(7b - 2) / (-a + 1)....a = -2, b = 3, c = -1/3
where is he c in this equation ? Because if I just use a and b, my answer is not an answer choice
(7b - 10) / (a - 1)...a = -1, b = 5, c = -2/3
same as before...where is the c in this equation
V = (pi) r^2* h
V = (pi)(5^2)(7)
V = (pi)(25)(7)
V = 175(pi)
