Camille rolls two number cubes together and records the sum. If she does this 180 times, how many times should she expect the sum to be 7?

i would say c is the best answer, hope it's right!

good luck! =)

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

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 : )
