87.1
remember a²+b²=c²
take the root on both sides, then you get what the calculation in the screenshot means.
T=b+2c+3j, if b,c,j are 8,3,4 respectively
t=8+2(3)+3(4)
t=8+6+12
t=26
So they chop down 26 trees.
Answer:
-37.5 m
Step-by-step explanation:
If we assume that "one full day" is 24 hours, then 15 hours represents the fraction 15/24 of a day. Since the drilling rate was constant, and was presumed to start from a height of 0, the height after 15 hours is that fraction of the day's work:
... (15/24)×(-60 m) = -37.5 m
Answer:
C) Chase did not make a mistake.
Step-by-step explanation:
( step#1 )
( step#2 )
Step 1: Divided each side of the equation by 1/3 which is correct.
Step 2: simplified from g - 3 = 9 to g=12
Therefore, Chase didn't make a mistake.

40/1 = 80/2 = 120/3 = 160/4 = 200/5 = 240/6 = 280/7 = 320/8 = 360/9 = 400/10 = 440/11 = 480/12 = 520/13 = 560/14 = 600/15 = 640/16 = 680/17 = 720/18 = 760/19 = 800/20
If that helps?
