20 percent because you could make it out of 100 so 1 x 20 = 20 and 5 x 20 = 100so I would say 20 percent

Which statements help explain this result? Check all that apply.
12345 [234]

Answer:

The bottle was 1/2 full at 11:35 a.m. and doubled again after 5 minutes.

The bottle was 1/4 full at 11:30 a.m. and doubled twice after 10 minutes.

Exponential growth involves a constant multiplicative rate of change.

Step-by-step explanation:

All that apply in the statements are as follows:

(a) The bottle was ½ full at 11:35 a.m. and doubled again after five minutes, which indicates that the bottle doubled at 11:40 am

(b) The bottle was ¼ full at 11:30 a.m. and doubled twice after 10 minutes. These means that the bottle was ½ full at 11:35 a.m. (i.e. five minutes ago the bottle was at ¼ full at 11:30 am, after five minutes, the which is was ½ full at 11:35 am but later became full at 11:40 am)

(c) Exponential growth involves a constant multiplicative rate of change (1.e. the rates of growth is twice every five minutes)

A rectangular piece of metal is 30 in longer than it is wide. Squares with sides 6 in long are cut from the four corners and the
Alexandra [31]

Answer:

length=53 in

width= 23 in

Step-by-step explanation:

First, we know that each corner has now a square of 6 in long, so the heigth of the box will be of this size (as you can see in the picture attached). Then, the length and the width of the box would be the same as the piece, but with 12 in less. Therefore the equations to solve the problem are:

h=6 in\\w=x-12\\l=x+30-12\\l=x+18\\\\V: volume of the box\\V=6*(x-12)*(x+18)\\2706=6x^{2}+36x-1296\\0=6x^{2}+36x-4002\\\\

We factorize the 6 and we get:

0=x^{2}+6x-667\\

Finally we solve for x, and we get the initial dimensions of the piece of metal:

x=23l=30+x=30+23=53 in\\w=x= 23 in
