Simply 2 1/2 divided by 1 1/3
alexgriva [62]

Answer:

15.8 (15/8)

Step-by-step explanation:

First, we turn the mixed numbers into fractions by multiplying the whole number by the denominator and this answer into the numerator:

2 1/2=5/2

1 1/3=4/3

now to divide, we keep the first fraction, change the divide to a multiply, and then flip the second fraction:

5/2·3/4

Now, simply multiply:

5/2·3/4=15/8 (15.8 if you need a decimal)

And you have your answer! hope this helped!

After a 2 1/2 hour rainstorm, there are 5 inches of water in a bucket outside. What is the rate per inch?
xeze [42]

Answer:

2 inches per hour

Step-by-step explanation:

2 1/2 hours is equivalent to 150 minutes.

Set up a proportion; let x equal inches of rain

\frac{5}{150}=\frac{x}{60}

Cross multiply -> 150x=300

Divide both sides by 150 to get -> x=2

35 POINTS ANSWER FAST PLZ!!!!!!!!!!!!!!!
Sladkaya [172]

The formula to solve for thee area of a square pyramid is [ V = 1/3 * b² * h ]

b² = base area (b = length of one side of the base)

h = height

The only option that as a base length of 12cm. and a height of 14cm. is the first option.

Solve for the volume if needed.

V = 1/3(12²)(14)

V = 1/3(144)(14)

V = 1/3(2,016)

V = 672cm²

Best of Luck!
