Answer: Your answer is -2 5/6
Step-by-step explanation:
Just convert the -2/3 to sixths. To do this, you multiply the denominator and numerator by 2 to make it equivalent to -2 1/6's denomenator (6). 2 times -2 is -4 and 3 times -2 is -6. This means -2/3 is equal to -4/6. As a result -2 1/6 - 4/6 is -2 5/6.
There are two ways to do this:
Way 1- Since you know there are 4 people and each will pay 25%, you know that every person will pay equally / the same amount so you can just do 115/4 and get $28.75 per person
Way 2- You can convert 25% into a decimal by multiplying it by 100 and getting 0.25 and multiplying 0.25 x 115 to get 25% of 115, which is what everyone will pay and you get B $28.75
Answer:
5 seconds
Step-by-step explanation:
H= -16t2 + 400
Hit ground
H=0
0 = -16t2 + 400
0 = -16 ( t2 - 25)
-16
t2 -25 = 0
(t + 5)(t - 5) = 0
t + 5 = 0
- 5 -5
t = -5
t - 5 = 0
+ 5 +5
t = -5
t = 5
5 seconds to hit the ground
The answer should be 9 if I’m not mistaken
Since he gets paid more for tutoring, he should work as many hrs tutoring as possible. He can only work at most 20 hrs. He has to work at least 3 hrs tutoring but no more then 8 hrs.....to maximize profit, he needs to work 8 hrs tutoring...leaving 12 hrs as a teachers aide. He should work 20 hrs to maximize his earnings.
maximum profit is : 8(10) + 12(7) = 80 + 84 = 164
