Hm
10 + 4 x 2 - 3
=10 + 8 - 3
=18 - 3
=15
I think it’s 18 and I will explain how I got that
Explanation: so first I added all the marbles she took out to see the total she took out which was 50 and if she did it 90 times I need to see how much time 50 she did it more and that was so 90 divided by 50 is 1.8 and that times 10 (times because we want to see how many times the red marble would come out) and that’s 18
So, if the pizza is cut into 8 slices that would mean we just have to subtract 6 - 8 = 2 so your answer is 2/8 of the pizza is left
Hope this helped!
Find the derivative of h and then find its root
<span>h = -16t^2 + 440t
h'=-32t+440
-32t+440=0
t=13.75 s
