Answer 3

so 75 * 2

Answer 4

You have to convert from watts to kw first

Answer 5

\[\frac{ 75watts }{ 1 } \times \frac{ 1 kw }{ 1000 watts } = 0.075 kw\]

Answer 6

Hours in two weeks:

\[24 \times 7 \times 2 = 336 hours\]

Answer 7

0.075*336

Answer 8

Correct

Answer 9

the first blank would be 0.075

Answer 10

No, remember 0.075 was obtained from converting 75 watts into kw, which is 0.075 kw. That is not kw-hour.

Answer 11

You converted from watts to kw earlier, then from kw to kw-hour. Just apply the same steps. I already got the value of the # of hours in a week for you.

Answer 12

1/1000=x/336

Answer 13

That :/

Answer 14

what is that

Answer 15

0.075 kw to kw-hour = 0.075 times 336

I don't know what you're solving for now.

Answer 16

25.2

Answer 17

Yes, in kw-hour

Answer 18

yay so to get the price it would be just multiplying it so 25.2 * 11.25

Answer 19

yes

Answer 20

283.5

Answer 21

okay so that would be thelast blank

Answer 22

now to figure out the blender

Answer 23

Start by converting 500 watts to kw

Answer 24

\[\frac{ 500 watts }{ 1 }*\frac{ 1Kw }{ 1000 } = 0.5\]

Answer 25

0.5*0.5=0.25

Answer 26

mhm, you know what to do next right?

Answer 27

0.25 would be the Kw-hour

and then


0.25*0.09=0.0225

Answer 28

Why did you convert to dollars? xD

Answer 29

I think they are fine with you leaving it in cents.

Answer 30

Wait what? What are you talking about lol

Answer 31

9 cents = $0.09

Answer 32

Yeah so wouldn't it be

0.25*0.09=0.0225

Answer 33

Only if you want it in dollars

If you do it in cents you do:

9 times 0.25 = 2.25 cents

A much more elegant number than 0.0225

Answer 34

Genius
