Aplumber uses 16 inches of tubing to connect each washing machine in the laundry source he wants to install 18 washing machine how many yards of tubing will he need

Step-by-step explanation:

Since each washing machine needs 16 inches of tubing we are going to multiply 16 by 18, the amount of laundry sources he wants to install. The answer to the multiplication problem is 288. Next we have to divide 288 by 36 since 36 inches are in a yard. The final answer is 8 yards. I hope this helped you out!

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
