<u>Answer:</u>

$80

<u>Step-by-step explanation:</u>

We are given that Sam tutors math and for each hour that he tutors, he earns 20 hours and we are to find the amount of money he earns if he tutors for 4 hours.

Sam's earning is given by:

E(h)=20h

where h is the number of hours that he tutors for.

Substituting the number of hours in the above equation to get:

E(h)=20(4)

E(h)=80

Therefore, Sam earns 80 dollars.

Airida [17]
If the required rate is gallons per minute, then its obvious from the question, that the rate of filling the pool is 10 gallons per minute, and its obviously a constant number. 
But for the rate to be in gallons per hour, then 
1 minute corresponds to 10 gallons
so 
1 hour corresponds to 10x60 = 600 gallons
hence
rate (gallons per hour) = 120,000/600 =  200 gallons per hour. 
which is again a constant number.

Rewrite this radicand as two factors, one of which is a perfect square.
seropon [69]

Answer:

2 \sqrt{15}

Step-by-step explanation:

1) rewrite 60 as it's prime factors.

\sqrt{2 \times 2 \times 3 \times } 5

2) group the smae prime factors into pairs.

\sqrt{(2 \times 2)}  \times 3 \times 5

3) Rewrite each pair in exponent form.

\sqrt{ {2}^{2} \times 3 \times 5 }

4) use this role:

\sqrt{ {x}^{2} }  = x

2 \sqrt{3 \times 5}

5) Simplify.

4 \sqrt{15}

So, therefor, the answer is option 1.

The sum of two consecutive odd integers is 28. What are the integers?
Fantom [35]
The correct option is B): "<span>Let x = 1st integer. Let x + 2 = 2nd integer.</span><span>"
Given that "The sum of two consecutive odd integers is 28."
 
Now the difference between two odd numbers is 2. So this means that one odd number has to be greater than the other by 2.

Let the smaller number be 'X' therefore the bigger number will be 'x+2' thus x + (x+2) = 28
 
therefore, x + x + 2 = 28 now we subtract "2" from both the sides
therefore, 2x = 26 now dividing throughout by 2 we get:

x = 13 therefore, x + 2 = 13+2
                                    = 15
 
therefore, the numbers are 13 AND 15</span>
