There are 60 children in the day care center. If 1/5 of the children are preschoolers, 2/3 of the children are toddlers, and the rest are Infants, find the number of children in each age group.

find common denominator

1/5

2/3

common denominator is 15

convert 2/3 into a fraction with a denominator of 15

1/5 —> 3/15

2/3 —> multipky numerator and denominator by 5 —> 10/15 (toddlers)

infants = total - toddlers - preschoolers

infants = 15/15 - 10/15 - 3/15 = 2/15

multipky the fractions by 60 (the total number of students) to find for the number in each age group

(10/15)*60 = 40

(3/15)*60 = 12

(2/15)*60 = 8

A linear graph is one with a line which has the same slope throughout. In this case, you can tell that the line doesn't have the same slope all the way through because it flats and also decreases in one section.

Increasing will mean the line's slope is positive, or it tends to go upwards. The slope will be constant, 0, so it's just a horizontal line. The slope of the line will decrease is negative, and it tends to go downwards. In this case, this would mean that segment k is., as it seems to go upwards, l is constant, because it's a horizontal line, and would be decreasing because it's going downwards.

I might assume that the ant began moving away from the hole for 2 seconds, then stopped for 3 seconds, and then went back to the hole for 3 seconds again.
