Part A
4 < 5 < 9 is given to us. Apply the square root to each term to end up with this inequality: sqrt(4) < sqrt(5) < sqrt(9)
So sqrt(5) is between sqrt(4) and sqrt(9)
-------------------
Part B
Simplify those two mentioned square roots
sqrt(4) = sqrt(2^2) = 2
sqrt(9) = sqrt(3^2) = 3
Therefore, sqrt(5) is also between 2 and 3
We can see this through using a calculator: sqrt(5) = 2.23607 approximately
-----------------
Part C
We can now say:
2 < sqrt(5) < 3
Multiply all three sides by 6
6*2 < 6*sqrt(5) < 6*3
So the expression 6*sqrt(5) is between 6 x 2 and 6 x 3
Sure enough, a calculator confirms this
6*sqrt(5) = 13.416408
since 6*2 = 12 and 6*3 = 18. We see that 13.416 is between 12 and 18.
Lee travels 38 miles per gallon of the gasoline.
Lee drove 420 miles and consumed 15 gallons of gasoline.
Miles per gasoline to determine travel by lee.
Average of the numbers is to sum of the number per unit total number.
Here, 420 miles = 15 gallon of gasoline
divide by 15 both sides
420/15 miles = 15/15 gallon of gasoline
38 miles = 1 gallon of gasoline
Thus, lee travels 38 miles per gallon of the gasoline.

(you have to move the decimal point to find the answer)
Answer:
R= 4
So that means
15(4)-6(4)=36
The (4) in parenthesis means multiply.
75/100=3/4
Therefore, the ratio is 3:4
