Answer:
There are 6 boxes
Step-by-step explanation:
We know there are 45 frames and 3 broken ones, so there are 48 frames in total.
We know there are 8 boxes that have the frames.
let x equal the amount of picture frames in a box
8x=48
8x/8 = 48/8
x=6
Answer:
Step-by-step explanation:
Given tq equation of the height reached by the rocket as y=-16x^2+235x+133
The velocity of the object at its maximum height is zero
v = dy/dx = 0(at max height)
v =-32x +235
0 =-32x+235
x = 235/32
x = 7.34
Hence the rocket will reach its maximum height after 7.34seconds

(E) 1/5
Step-by-step explanation:
The probability that Harry will be chosen to be the secretary but not the president is ![\frac{9}{10} *\frac{1}{9} =\frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B10%7D%20%2A%5Cfrac%7B1%7D%7B9%7D%20%3D%5Cfrac%7B1%7D%7B10%7D)
The probability that Harry will be chosen to be the treasurer but not the president or secretary is ![\frac{9}{10} *\frac{8}{9}*\frac{1}{8}=\frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B10%7D%20%2A%5Cfrac%7B8%7D%7B9%7D%2A%5Cfrac%7B1%7D%7B8%7D%3D%5Cfrac%7B1%7D%7B10%7D)
Thus, the probability that Harry will be either the member chosen to be the secretary or the member chosen to be the treasurer is ![\frac{1}{10} + \frac{1}{10} = \frac{1}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D%20%2B%20%5Cfrac%7B1%7D%7B10%7D%20%3D%20%5Cfrac%7B1%7D%7B5%7D)
