PLEASE ANSWER QUICKLY Joe is saving up to buy a computer. The components will cost $500 and he will have to pay $20 an hour for the
system to be built. If Joe's bill was $1200, how many
hours did it take to build his computer?

85 Hours

Step-by-step explanation:

1,200 - 500 = 1700

1700/20 =

85 hours

try soting them out first

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 : )
