I think I did the second one for you earlier.
First one:
216*(2/3) = (\sqrt[3]{216})^2 = 6^2 = 36
Answer:
the first option
Step-by-step explanation:
i know there's a rule to all of this but it's been a while since i've done this kind of math.
if you plug in the zeros to the equation, they solve
(-2, 0) --> (-2-2)(-2+1)(-2+2) = 0
(-1, 0) --> (-1-2)(-1+1)(-1+2) = 0
(2, 0) --> (2-2)(2+1)(2+2) = 0
Answer:
14
Step-by-step explanation:
Keep, change, flip!
7/8 / 1/16
7/8 x 1/16
7/8 x 16/1
Equals...
112/8
Which can be simplified to...
14!
Hope this helped!
Answer:
Jessica needs to score at least 88.2 (or 88) on her last test.
Step-by-step explanation:
So, her average so far is the sum of the five scores divided by the number of tests she has taken so far.
(87 + 81 + 85 + 90 + 78)/5 = 84.2
(87 + 81 + 85 + 90 + 78)/5 < 85 :(
She will not get into that college if she doesn't increase her average on the last test.
85 - 84.2 = 0.8
0.8(5) = 4.0
On her last test, she needs to score 4 points higher than her current average in order to get into the college.
84.2 + 4 = 88.2
Hope this helped :)
