At the beginning of the quarter there were 40 students in our class. At the final exam, there are only 32 students left. By what percent did the class size decrease? by 96

20 % decrease

Step-by-step explanation:

First find the number of students that left

40 -32 = 8

Take the number of students that left and divide by the original number of students

8/40

1/5

.20

20%

20 % decrease

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
