Each day, Steven walked 1/12 mile more than the previous day. The first day he walked 1/12, the second day he walked 2/12 mile, the third day he walked 3/12 mile. On which day did the sum of his walks total at least 1 complete mile?

12th day

Step-by-step explanation:

First day:  1/12 mile:  note the '1' in '1/12.'

Second day:  2/12 mile

Third day:  3/12 mile

One complete mile would therefore be 12/12 mile, achieved on the 12th day.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
