Answer:
I would say 85, since 85 would be the median of the three points or 8 hours of studying. I hope this helps! :)
Answer:
16 = l
4 = w
Step-by-step explanation:
{64 = wl
{40 = 2w + 2l
{l = 8 + 2w
64 = w[8 + 2w] ↷
-64 + 8w + 2w² ↷
[2w² - 8w] + [16w - 64]
2w[w - 4] 16[w - 4]
[w - 4][2w + 16] = 0
↑
This is the expression we want because when we talk about dimensions, we want NON-NEGATIVE numbers. The other expression results in -8 = w, and we do not want that; this expression gives us a solution of 4 = w, and THIS is exactly what we want. Anyway, you plug "4" back into the system of equations and you will get a length of 16 centimetres.
I am joyous to assist you anytime.
480 people is 75 %
x people is 100 %
--------------------------
480 : x = 75 : 100
75 x = 48,000
x = 48,000 : 75
x = 640
Answer:
D ) 640 people
