Which is the best estimate for the sum of 5/1 + 2/5?
(a) 0 + 0 = 0
(b) 1/2 + 0 =1/2
(c) 1 + 1 = 2
(d) 1/2 + 1/2 =1

idk

step-by-step explanation:

1st part is 64,000,000

2nd part 500,000

step-by-step explanation:

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 : )
