Question

i will medal please help A 175-pound cyclist burns 672 calories for every hour of cycling.



Round the number of calories to the nearest hundred and then estimate.



About how many calories would the cyclist burn in 10 hours?

Answer 1

You round 672 up to the nearest hundred, which would be 700, then multiply that by 10. The easiest way to multiply by 10 is to add on one more 0!

Answer 2

672 rounded to the nearest hundred is 700.
672---> 700

Multiply 10 and 700 to find out about how many calories he has burned in 10 hours.
700*10
7000

He would burn about 7000 calories in 10 hours.

Answer 3

ok but thats confusing

Answer 4

because you would multiply 672 calories by 10 hours and you would get 6,700 calories

Answer 5

why is it confusing?

Answer 6

im bad at math

Answer 7

its not confusing

Answer 8

672 is greater than 649, so it rounds up to the nearest hundred. this is because, when you round to the nearest hundred, if the tens number, which is 70 in your example, is 50 or more, you round up. if it is below 50, you round down.

Answer 9

yes so 700 x 10

Answer 10

when you multiply anything by a number like 10, or 100, you will always add the number of zeros in the 10 number to the end of the other number. EX:
100 * 25 = 2500.
So for this equation, it would be 10 * 700 = 7000
