Six cell phones weigh 46.2 ounces. Fourteen cell phones weigh 107.8 ounces. What is the unit rate or constant of proportionality?

Well first we must see if they are proportional.

46.2/6 = 10.7.8/14

7.7 = 7.7

They are proportional. The rate of proportion is 7.7 ounces per cellphone. Hope this helps!

step-by-step explanation:

what was your answer?

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
