Answer:

The number of pools clean per hour is 1.5

Step-by-step explanation:

Given as :

The number of pools clean in 8 hours = 12

The number of pools clean in 7.5 hours = 9

Let The number of pools they clean per hours = x

I.e x = \frac{8}{12} +  \frac{7.5}{9}

Or, x =  \frac{24+30}{36}

Or, x =  \frac{54}{36}

∴   x =  \frac{3}{2}

I.e x = 1.5

Hence The number of pools clean per hour is 1.5 Answer

Andy drove 840 miles in 12 hours. How far could he drive in 3 hours?​
liraira [26]
To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.

John wrote the numbers 678,901 and 67,890. How many times greater is the value of 7 in 678,901?​
worty [1.4K]

Answer:

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890

Step-by-step explanation:

step 1

we have

678,901

Write in expanded form

678,901=600,000+70,000+8,000+900+1

The value of 7 is 70,000

step 2

we have

67,890

Write in expanded form

67,890=60,000+7,000+800+90

The value of 7 is 7,000

step 3

Divide 70,000 by 7,000

\frac{70,000}{7,000}=10

therefore

The value of 7 in 678,901 is 10 times greater than the value of 7 in 67,890

What’s the numerator for the following rational expression s/t+7/t=?/t
avanturin [10]

Answer:

s+7 is numerator of the given expression.

Step-by-step explanation:

We have bee given a rational expression:

\frac{p}{q} is the general representation of the Rational expression where, p is numerator and q is denominator.

So, our given expression is:\frac{s}{t}+\frac{7}{t}

We will take the LCM so, given expression can be rewritten as:

\frac{s+7}{t}     (1)

Comparing (1) with general rational expression written above

p=s+7 which is numerator of the given expression.

What is the radius of
Nana76 [90]

Answer:

Radius of cylinder = 2 inch (Approx.)

Step-by-step explanation:

Given:

Volume of cylinder = 75.4 in³

Height of cylinder = 6 inches

Find;

Radius of cylinder

Computation:

Volume of cylinder = πr²h

Volume of cylinder = (3.14)r²(6)

75.4 = (18.84)r²

(Radius of cylinder )² = 75.4 / 18.84

(Radius of cylinder )² = 4.002123

(Radius of cylinder) = 2

Radius of cylinder = 2 inch (Approx.)
