For her science project, sofia is investigating the relationship between age and the effect of caffeine on heart rate. she assigns the 300 study participants to group a, group b, or group c. each group is given a beverage containing a different level of caffeine, and sofia measures each participant's heart rate before and after he or she consumes the caffeinated beverage. which of the following research methods is sofia
using?

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

the answer is 8/21

hope this

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
