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 1
Answer:

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.
Answer 2
Answer: 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.

What special marks are used to show that segments are congruent? A. midpoint B. hashmarks C. angle bisector D. arcs

Answers

The correct answer is:


B) hashmarks.


Explanation:


When two line segments are congruent, we mark this using small dashes through the segments. These dashes are called "hashmarks."
"Hashmarks" is the one special mark among the choices given in the question that are used to show that segments are congruent. The correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that has come to your help.

Choose the method of pay that would result in the most earnings for one month on sales of $40,000.a.
Straight commission of 7.5% on all sales.
b.
Monthly salary of $1,600 plus 2.5% commission on all sales.
c.
Graduated commission of 5% on the first $30,000 in sales and 6% on anything over that.
d.
Graduated commission of 4% on the first $25,000 in sales and 8% on anything over that.

Answers

The option that results in the most earnings for one month on sales of $40,000 is option a. Straight commission of 7.5% on all sales.

To determine which method of pay would result in the most earnings for one month on sales of $40,000, let's calculate the earnings under each option:

a. Straight commission of 7.5% on all sales:

  Earnings = 7.5% of $40,000 = 0.075 * $40,000 = $3,000

b. Monthly salary of $1,600 plus 2.5% commission on all sales:

  Earnings = $1,600 (monthly salary) + 2.5% of $40,000 (commission) = $1,600 + 0.025 * $40,000 = $1,600 + $1,000 = $2,600

c. Graduated commission of 5% on the first $30,000 in sales and 6% on anything over that:

  Earnings = (5% of $30,000) + (6% of $40,000 - $30,000) = (0.05 * $30,000) + (0.06 * $10,000) = $1,500 + $600 = $2,100

d. Graduated commission of 4% on the first $25,000 in sales and 8% on anything over that:

  Earnings = (4% of $25,000) + (8% of $40,000 - $25,000) = (0.04 * $25,000) + (0.08 * $15,000) = $1,000 + $1,200 = $2,200

The option that results in the most earnings for one month on sales of $40,000 is option a. Straight commission of 7.5% on all sales.
