Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that 
\sqrt{72} (<span>8.4852...)
</span>is equal to 
2* \sqrt{36} (12)

If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.

So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!

(-16,20),(-6,-15) what’s the slope
Sonbull [250]

Answer:

-3.5

Step-by-step explanation:

To find the slope we use

m = (y2-y1)/(x2-x1)

   = (-15-20)/(-6 - -16)

   =(-15-20)/(-6+16)

   -35/10

   = -3.5

P=-30h+74 The variable h represents the number of hours he has spent reading, the variable p represents the number of pages left
olchik [2.2K]

Answer: Ethan will have to spend 2 hours reading if 14 pages are left to read

Step-by-step explanation:

Given the equation

P=-30h+74

where p =number of pages left to read and

h= the number of hours he has spent reading

Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be

P=-30h+74

14= -30h + 74

30h= 74-14

30h= 60

h = 60/30

h =2 hours

Ethan will have to spend 2 hours reading if 14 pages are left to read
