x = 26 m is the width of the pool, length: 29+4 = 33 m.
<u>Step-by-step explanation:</u>
We have A rectangular pool is surrounded by a walk 3 meters wide. The pool is 4 meters longer than its width. If the total area of the pool walk is 372 square meters more than the area of the pool.
Let the width of the pool = x
Then the length will = (x+4) ,over all dimensions will be (x+6) by (x+6+4) or (x+10)
Total area - pool area = 372
∴ x = 26 ft is the width of the pool, length: 29+4 = 33 ft
function rule describes the amount of profit that will be made by the student council on the shirt sales is .
<u>Step-by-step explanation:</u>
Here we have , student council at Smith Valley High School is planning to sell t-shirts as part of a fundraiser using company A, the shirts cost $4.50 each. The student council has to pay the shirt company a design fee of $45. the shirts will be sold for $12 each. We need to find a function rule describes the amount of profit that will be made by the student council on the shirt sales . Let's find out:
Each shirt cost $4.50 . The student council has to pay the shirt company a design fee of $45. the shirts will be sold for $12 each , So the total amount of t shirt he sell is :
⇒ , where x is the number of t shirts !
Now , expenses is given by :
⇒ , where x is the number of t shirts !
So , Profit made is :
⇒
⇒
Therefore , function rule describes the amount of profit that will be made by the student council on the shirt sales is .
