Jamal works as an electrician’s apprentice. he rewired 4 electrical outlets in 1 1/2 hours. if he works at the same pace for 7.5 hours, how many outlets will he rewir?

20 outlets.

Step-by-step explanation:

We know that Jamal rewired 4 electrical outlets in 1 1/2 hours. This time can be rewritten as a decimal:

 Then, if he works at the same pace for 7.5 hours you can calculate the number of outlets that he will rewire with:

Being "x" the number of outlets that Jamal will rewire.

Finally, you have to solve for "x":

He will rewire 20 outlets.

m∠a is 90°

m∠b is 40°

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
