How many bricks 3.75 in. Wide × 8 in. Long are required to cover a patio 13 ft. 6 in. Wide by 18 ft 9 in. Long ?Step 1. First, find the total width & length of the patio in inches.

Step 1a. Convert the portion of width and length that is expressed in feet to inches.

Width: 13 ft = 13 × ___ = ___in

Length: 18 ft = 18 × ____ = _____ in

Answers

Answer:

1215 bricks will be required.

Step-by-step explanation:

Length of a brick L= 8 in. and width of the brick w = 3.75 in.

Area of one brick = 8×3.75 = 30 in²

Now length of a patio = 13 feet 6 in

since 1 feet = 12 inch.

So length of the patio = (13×12 + 6)= 162 in

Similarly width of the patio = 18 feet 9 inch = (18×12 + 9) = 216 + 9 = 225 inch

Area of the patio = 162×225 = 36450 in²

Now total bricks required to cover patio = Area of patio ÷ area of one brick

                                                                   = 36450 ÷ 30 = 1215 bricks

Therefore 1215 bricks will be required to cover a patio.
Ab = (3.75/12)*(8/12) = 0.20833333 ft^2. 
= Area of each brick. 

Ap = 18.75 * 13.5 = 253.125 Ft^2. = 
Area of patio. 

Bricks = Ap/Ab = 253.125/0.20833=1215. 

Round 24,732 to the
nearest thousand.

What needs to be done before you try to solve the equation 2x2 = -6+ 8a?

Answers

Answer: You need to separate the variable (A) from the rest of the equation.

Step-by-step explanation:

Simplify and move everything except the variable
2x2 = -6 + 8a >>> 4 = -6 + 8a >>> 10 = 8a
Then, divide both sides by the amount of A (8)
10 / 8 = 1.25
8 / 8 = 1
1.25 = A
