Given that a square patio of at least 80 square feet is to be built from 125 tiles of length 12 inches or 1 feet.
Part A;
Since there are 125 tiles and the patio has a shape of a square of at least 80 square feet, then the possible dimensions of the patio are
9 ft by 9 ft = 81 ft
10 ft by 10 ft = 100 ft, and
11 ft by 11 ft = 121 ft.
Part B.
For a patio of dimensions, 9ft by 9ft, the number of tiles that will not be used is given by 125 - 81 = 44
For a patio of dimensions, 10ft by 10ft, the number of tiles that will not be used is given by 125 - 100 = 25
For a patio of dimensions, 11ft by 11ft, the number of tiles that will not be used is given by 125 - 121 = 4
Answer:
x=1.528534
Explanation:
Simplify both sides of equation
4(2x-3)=0.2(x+5)/5.72
(4)(2x)+(4)(−3)=0.034965x+0.174825(Distribute)
8x+−12=0.034965x+0.174825
8x−12=0.034965x+0.174825
Step 2: Subtract 0.034965x from both sides.
8x−12−0.034965x=0.034965x+0.174825−0.034965x
7.965035x−12=0.174825
Step 3: Add 12 to both sides.
7.965035x−12+12=0.174825+12
7.965035x=12.174825
Step 4: Divide both sides by 7.965035.
7.965035x/7.965035=12.174825/7.965035
x=1.528534
X is sugar
y is butter
z is total money
$0.80x + $1.25y = z
the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.
