Answer 1

try finding how many words a student can type in 1 minute

Answer 2

i thought so too @ParthKohli but look at 7 minutes

Answer 3

how about adding 7 mins and 3 mins?

Answer 4

umm, 7+3 = 10

Answer 5

Oh yeah it'd be multiply that by 7.

Answer 6

like i said lol :p

Answer 7

im getting too slow at the keyboard in my old age

Answer 8

Sorry :(

Answer 9

Weird how all 99's are answering the question.

Answer 10

ok so is someone going to help me

Answer 11

its not that hard to get to a 99 ...

Answer 12

we just did?

Answer 13

does sherri define help as: just give me the answer?

Answer 14

7 + 3 = 10
This is how it's done

Answer 15

a student can type 180 words in 3 minutes

368 words in 7 minutes

7 minutes + 3 minutes = 10 minutes

therefore add how many words the student types in 3 minutes + how many words the student types in 7 minutes

Answer 16

180 + 368 = ?

Answer 17

Seems to be a non-linear function of time.

Answer 18

Exactly. The ratio isnt constant. I dont think you can just add it up.

Answer 19

this doesnt seem to be a "fit a curve" question.

it gives a 3 minute and a 7 minute value and asks for a 10 minute value

Answer 20

We have to find the rate of change here Iguess

Answer 21

I know, Amistre. I was being tongue-in-cheek.

Answer 22

:) i had considered using 0,0 and determining a sqrt or ln to fit tho

Answer 23

or parabola depending on where the points fall

Answer 24

a bajillion is my guess tho

Answer 25

Hmm.. Maybe we can solve it generally?

Answer 26

470?

Answer 27

Actually, it's 42. It's definitely 42.

Answer 28

cant we just agree on the simple imaginary solution :p lol

Answer 29

Hmm.. Maybe you're right, lgba.
