Answer:
He needs 5x+56 ft
Step-by-step explanation:
To find how much of fencing he needs , we find the perimeter of the given figure
All sides are equal in a square
To find perimeter of the square we add all the sides
4 sides we have for the square
one side is x, so perimeter of square = x+x+x+x= 4x
Now we find perimeter of rectangle
Opposite sides of rectangle are equal
Here for rectangle we consider only three sides
because fourth side is common for rectangle and square
So perimeter of the rectangle (with 3 sides) = 28 +x+ 28 = 56+x
Total fencing = perimeter of square + perimeter of rectangle
4x + 56 + x= 5x+56
Volume of Cylinder = πr²h
Radius r = 14.5 feet
Volume, V = 4950 cubic feet
4950 = π*14.5²*h
π*14.5²*h = 4950
h = 4950 / (π*14.5²) Use your calculator with π function
h = 7.494
Therefore height ≈ 7.50 feet to the nearest tenth of a foot.
Answer:
y=8
Step-by-step explanation:
substitute (plug in) 5 for x because it says that the value of x is 5
Answer:
Break-even point is at quantity 220.
Step-by-step explanation:
Given the rent amount that is fixed cost for the store = $550
The average cost of the goods = $3
The average price of the goods = $5.50
Let the total number of break-even items = Q
Thus, total revenue = 5.50 x Q = 5.50Q
At break-even, TR = TC
5.50Q = FC + VC
5.50Q = 550 + 3Q
5.50Q - 3Q = 550
2.50Q = 550
Q = 550 / 2.50
Q = 220
Thus break-even point is at quantity 220.
Answer:
A. f(-1) = -3, f(7) = 13
Step-by-step explanation:
✔️When input (n) = -1:
f(n) = 2n - 1
f(-1) = 2(-1) - 1
f(-1) = -2 - 1 = -3
✔️When input (n) = 7:
f(n) = 2n - 1
f(7) = 2(7) - 1
f(-1) = 14 - 1 = 13
