Pool and deck = 60 ft by 50 ft
First question: Area of the deck including the deck
A = 60*50 = 3000 ft^2
Average cost = $4,560
Discount offered = 20%
Second question: Cost after discount
This is a question of proportionality. That is;
$4,560 ------------ 100%
Actual cost ------ (100-20)% -----80%
Then,
Actual cost after discount = (4,560*80)/100 = $3,648
Area of the pool is 750 ft^2 and one side is 30 ft.
Third question: Length of the other side
Area = L*W, if Length, L = 30 ft, Width, W = ??
750 = 30*W
W = 750/30 = 25 ft.
Then, the other side is 25 ft long.
Cost per 10 ft length of fence costs $25.50
Fourth question: Total cost of fencing
Circumference = 2(L+W) = 2(60+50) = 220 ft
Number of 10 ft sections = Circumference/10 = 220/10 = 22 sections
Total cost = number of sections*Cost per section = 22*25.50 = $561
Answer:
2, I think. Lines 1 & 2 and lines 7 & 4 are perpendicular
edit: 3 pairs, 3 & 5 is the last one
Step-by-step explanation:
Answer:
$7.5
Step-by-step explanation:
Let
Quantity of stickers=x
Price of stickers=y
5 stickers cost $3
12 stickers cost $y
x/y = x/y
5/3 = 12/y
Cross product
5y=12*3
5y=36
Divide both sides by 5
5y/5 = 36/5
y=7.5
12 stickers= $7.5
Therefore, the price of 12 stickers= $7.5
First you find the area of the circle using the radius then multiplying that to the height. That gets the full volume. Using that measurement multiply it by 5/6 to figure out what 5/6 of the volume is. Good luck!
The complex conjugate of a + bi is a – bi, and similarly the complex conjugate of <em><u>a – bi is a + bi. </u></em>
