Jen and jacob want to put a cement deck around their pool. if the cement cost $4.75 per square foot, how much is the cost of the deck? round to the nearest hundreth.
90 minutes = 1.5 hrs
45 minutes = 0.75 hrs
8*5 - (1.5 + 0.75 + 2.5 )
40 - 4.75
35.25 = 35 1/4 hours = 35 hours and 15 minutes
Wrong answer
Width of pool is x+3
Length of pool is 3x-4
Width of deck is 3x-2
Length of deck is 2x+6
area= (2x+6)(3x-2) - (3x-4)(x+3)
= 6 x^2 + 14 x -12 -[ 3x^2 +5 x -12 ]
= 3 x^2 + 9 x
110.4375
To calculate the cost of the cement deck, we need to know the area of the deck in square feet. The area of a rectangle, such as the deck, is calculated by multiplying the length by the width.
However, since the dimensions of the deck are not provided in the question, we need more information to proceed. Once we have the dimensions (length and width) of the deck, we can use the area formula mentioned above.
For example, if the deck is 25 feet long and 15 feet wide, the area would be:
Area = Length x Width
Area = 25 ft x 15 ft
Area = 375 square feet
Next, we can calculate the cost of the deck. Given that the cement costs $4.75 per square foot, we multiply the area by the cost per square foot:
Cost of the Deck = Area x Cost per Square Foot
Cost of the Deck = 375 sq ft x $4.75/sq ft
Cost of the Deck ≈ $1781.25
Therefore, the cost of the deck would be approximately $1781.25.
