A car averages 27 miles per gallon. If gas costs $4.04 per gallon, which of the following is closest to how much the gas would cost for this car to travel 2,727 typical miles?a. $44.44


b. $109.08


c. $118.80


d. $408.04


e. $444.40

Answers

(D) 408.04 is the correct answer. If you divide 2,727 miles by 27 miles per gallon you will get the number of gallons: = 101. Then, multiply the number of gallons by the cost per gallon: 101(4.04) = 408.04. This gives the cost of gas for this car to travel 2,727 typical miles. Hope this helps!
d. $ 408.04 is the answer

Round 939,515 to the nearest ten

Answers

The number  939,515 rounded to the nearest tens is 939520.

What is rounding off of numbers?

We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.

To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.

Given, A number 939515 and we have to round it to the nearest ten.

To round this number to the nearest ten we'll look at the digit at the unit's place.

The digit at the unit place is 5 so we'll add 1 to the tens digit and make the unit digit zero.

Therefore the number 939515 rounded to the nearest tens place is

939520.

David recorded his finishing time, in seconds, for each time he ran the 100 m race during one track season. What was the median of his finishing times?11. 9 11.9 12.0 12.1 12.1 12.2 12.3 12.4 12.4

Answers

The median is 12.1 because it is the center number in the sequence. This only applies if the numbers are in order from least to greatest, and also if there are a even number of numbers in the sequence you must take the average of the two center ones because there is no center one.
