A rectangular swimming pool measures 14 feet by 30 feet. The pool is surrounded on all four sides by a path that is 3 feet wide.
If the cost to resurface the path is $2 per square foot, what is the total cost of resurfacing the path?
2 answers:
Answer:
$600
Step-by-step explanation:
The total width of the pool and path is 14 + 3 + 3 = 20 feet.
The total length of the pool and path is 30 + 3 + 3 = 36 feet.
The area of the path is the total area minus the area of the pool.
A = WL − wl
A = (20)(36) − (14)(30)
A = 720 − 420
A = 300
The area of the path is 300 ft². If the cost to resurface the path is $2/ft², then the total cost is:
C = 300 ft² × $2/ft²
C = $600

For this case we have the following quadratic equation:
To factorize, we must find two numbers that when multiplied result in -6 and when added together result in +5. These numbers are: -1 and +6
Then we factor:
Thus, the roots are:

Answer:
1.172 dollars per pound
Step-by-step explanation:
Given : A pet supply store sells a 20-pound bag of dog food $23.44.
To Find :Find the unit price.
Solution :
Cost of 20-pound bag of food = $23.44
So, Cost of 1-pound bag of food =
=
For unit price we should divide the cost by no. of pounds
So, the error is you have divided the no. of pounds by cost
Hence the unit price is 1.172 dollars per pound
