How do you Simplify 3/12?
densk [106]
You need to find a number that can go into both 3 and 12. 3 can go into 3 and 12. So, you would then find out, how many times does 3 go into this number? Well, 3 goes into 3 once of course, and 3 goes into 12 four times. (3 x 4 = 12) In a fraction, this would be 1/4. (1/4 is the simplification of 3/12)

Each month, you get your water bill in the mail. You know that each month you are charged a service
Svetach [21]

Answer:

$0.004 per gallon

Step-by-step explanation:

Given:

Service Fee= $22

Fixed rate per gallon= m

Water Consumed= 2256 gallons

Total bill charged= $31.02

Now by computing the equation we get

\textrm{Total bill charged} = \textrm{Service fee} + (\textrm{fixed charge per gallon} \times \textrm{water consumed})

Substituting data we get

22+m2256=31.02

m2256= 31.02-22

m2256=9.02

\therefore m =\frac{9.02}{2256} =0.00399

Rounding off above value we get

m=0.004 per gallon

Yuki888 [10]

Answer:

A

Step-by-step explanation:

So we want to convert 59°F to Celsius using the given formula:

C=\frac{5}{9}(F-32)

Thus, substitute F for 59:

C=\frac{5}{9}(59-32)

Subtract:

C=\frac{5}{9}(27)\\

Simplify:

C=\frac{135}{9}=15\textdegree F

The answer is A
