Answer 4

HELP @iPwnBunnies can u help plz

Answer 5

A rate is the amount of something per unit time. It's a division thing. So, for Fiona, she read 45 pages in 3 hours.
\[rate = \frac{45 pages}{3 hours} = 15 \frac{pags}{hour}\]

Answer 6

Do the same for Albert. And you can compare.

Answer 7

C

Answer 8

Correct. c:

Answer 9

thanks Bunnies

Answer 10

can u help with a little more plz more medals 4 u :)

Answer 11

I'll try.

Answer 12

great ok

Answer 13

Which statement is true concerning the graph of two lines showing the given rates?

Rate 1: 16 gal in 4 min
Rate 2: 18 gal in 6 min

A.
The graph with Rate 1 passes through (2, 6).

B.
The graph with Rate 2 passes through (2, 6).

C.
The graph with Rate 1 passes through (6, 2).

D.
The graph with Rate 2 passes through (6, 2).

Answer 14

First, find the simplest form of both rates. The same as we did in the last problem. This is equivalent to the slope of the line that can be made.

Answer 15

C

Answer 16

.-. Why would it be C. Where's your work?

Answer 17

let me guess it is not C now is it :(

Answer 18

.-. Stop guessing.

Answer 19

kk sorry :(

Answer 20

can u give me a hint plz? :)

Answer 21

I told you to simplify the both Rate 1 and Rate 2.

Answer 22

ok got it

Answer 23

rate 1: 64

rate 2: 108

Answer 24

multiplied

Answer 25

No. o.o What. In the last problem, I told you rate was a division thing. Amount per unit time.

Answer 26

oops sorry i forgot

Answer 27

Rate 1 =4

rate 2 =3

Answer 28

divided this time :)

Answer 29

MHm. c: You can look at it this way. For rate 1, for every minute, the amount of gallons go up by 4. It's basically a line with slope 4.

Answer 30

Apply the same concept to the second rate, and you'll see your answer. The point is written as (x,y) of course. Remember, x is the independent variables, which is time in this case.
