After batman brought the joker to justice , the crime rate in arkham city decreased by 12%. Previously the crime rate was c inci
alexandr402 [8]

Previous crime rate = c incidents per 1,000 people

Reduction in crime rate after batman brought the joker to justice = 12%

Hence, new crime rate (per 1,000 people) would be = c - 12%×c

⇒ New crime rate (per 1,000 people) would be = c - 0.12×c

⇒ New crime rate (per 1,000 people) would be = 0.88×c

Jenny is knitting a blanket. She knits 1/3 foot of the blanket in 2/3 of an hour. How fast is jenny's knitting speed, in feet pe
ycow [4]

Answer:

Jenny will knit 8 inches per each hour.

Step-by-step explanation:

First I know that 1 foot is 12 inches.

1/3 of 13 is 4.

1 hour is 60 minutes.

2/3 of 60 is 40.

so she knits 4 inches in 40 minutes.

We will now add 1/3 to both to see how many inches/feet she knits per hour/60 minutes.

Adding 1/3 to 2/3 of an hour will look like:

\frac{20}{60} +\frac{40}{60}

That equals 60/60 which is 1 hour.

Adding 1/3 to 1/3 of a foot will look like:

\frac{4}{12}+ \frac{4}{12}

That equals 8/12, which is 8 inches in a foot.

This means that in one hour, Jenny will knit 8 inches of a foot.
