Answer:
$21
Step-by-step explanation:
-11.00 + 44.50 = 35.50
35.50 - (6.25 * 2) = 21.00
The area of the only deck is 528 ft²
<u><em>Explanation</em></u>
The length and width of the swimming pool are 20 ft and 12 ft respectively.
So, <u>the area of the swimming pool</u>
Now a deck is being built around the pool and it has a uniform width of 6 ft.
So, the length of the pool including the deck and the width of the pool including the deck
Thus, <u>the area of the pool including the deck</u>
So, the area of the deck only

Answer:
5.5+106 square inches
Step-by-step explanation:
The wooden frame has different shapes- semi circle, rectangles and we would have to calculate area of all the shapes to get the wood required.
To get area of the circle, we use the formula π(R²-r²)/2. Subtract the inner radius from the outer radius =
π(6²-5²)/2= 11π/2
=5.5π square inches
We add area of the semi circle to area of the 3 rectangles from the diagram:
2×1×48×10×1=106 square inches
The rectangle with 10 inches is because we subtracted one inch from both sides of the 12 inches rectangle to avoid repetition and overvaluing the area
Total area =5.5π +106 square inches
Options must have ommitted the "π"
Divide 2.40 by 5 so you can find the unit rate.
2.40/5=0.48
So the price per fluid ounce is $0.48

Answer:
middle term = 7x
Step-by-step explanation:
in order to find the middle term, we will expand the bracket on the left hand side and compare the expressions on both sides.
(x + 2) (3x + 1) = 3x² + ___ + 2
let the unknown expression = y
(x + 2) (3x + 1) = 3x² + y + 2
Expanding the bracket on the left hand side by multiplication:
x + 2( 3x + 1) = (x × 3x) + (x × 1) + (2 × 3x) + ( 2 × 1)
= 3x² + x + 6x + 2
= 3x² + 7x + 2
Comparing with the expression on the right hand side:
3x² + 7x + 2 = 3x² + y + 2
∴ y = 7x
middle term = 7x
