Ratios can be written as fractions
24:28 = 24/28...this can reduce to 6/7....as a ratio 6:7
if that is not an answer choice, then any fraction that is equivalent to 24/28, written as a ratio will be ur answer
Hey hey!
56 would be the answer.
WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.
Here’s how I got the answer:
7:4 walls = 10:8 people =M:40 minutes
M = (7/4) / (10/8) x 40
M = 56 minutes.
If that helped let me know by hitting the thanks button or reply with any help you need.
Have a FABULOUS DAYYY!
R=-1/800(x^2-2400x)
use R'=0
R'=1/400x-300, 1/400x=300 => x=1200 critical point
take R(1200), we know its max bcuz of the orientation of R
