whats 30 percent of 70=.30 X 70=21

Divide Tbs by sq.ft=2/4=1/2 Tbs per sq.ft

what is x when the problem is 16=-4(x-3)

 16=-4(x-3)

16=-4x +12

16-12=-4x

4=-4x

x=-1

2/3 X 12=24/3=8

If you have 12 boys and 16 girls in the class, then the ratio is 12:16 or 1:1 1/3 boys to girls.

The price of a 250$ cost increaed 7% last year.The cost is now on sale for one-half off.What is the sale price .show work

The cost of the item was increased by 7%,

So the new price was 1.07 X 250=$267.50

So with half off means=267.50/2=$133.75 The sale price.

54 - (-2)*(-2)^2 + 3*(4^3) = 54 +2*4 + 3*64 = 54 + 8 + 192 = 62 + 192 = 254

Questions themselves can't be biased. Answers, however, can be biased.

Another way to do this is to separately calculate the sales tax and add it to the original cost.

55.80 + (55.80*.027 = 1.5066) = 57.3066

And don't forget to round to the hundreds place. We are talking about money after all.

ikr

55.80 * 1.027 = 57.3066

add 2.7% (sales tax) to 100% (original cost)  to get 102.7% (final cost)

102.7% is the same as 1.027

Cool

You could have just said 202.5/6 = 33.75 or 135/4 = 33.75.

Don't average out every previous gpa. Calculate gpa normally, but include all data from the past.

hi i asked you to marry me and got rejected

In 1 minute Sophie does 1/45 of the job.

In 1 minute Simon does 1/30 of the job.

Their combined rates is 1/45 + 1/30=1/18 of the work done in 1 minute.

Therefore the whole combined work would be finished in 18 minutes.

If everything you wrote out is correct, then you are right. The answer key is wrong. Those things are not always perfect.
