Min Jee wants to build a small patio using either brick or paver stones.It will be 70 inches long and 49 inches wide. Each brick covers an area of 3 1/2 inches by 7 1/2 inches, and cost $0.59.
Each paver covers an areas 8.4 inches by 8.4 inches and costs $1.88. What would be less expensive to use, and by how much?

Answers

Brick = 3.5 in by 7.5 in and costs $0.59
Paver = 8.4 in by 8.4 in and costs $1.88

The small patio's area = 3430 square inches
The Area of 1 Brick = 26.25 square inches
The Area of 1 Paver = 70.56 square inches

The # of Bricks to complete the Patio will be:

Patio's Area / the Area of 1 Brick = # of Bricks to complete the patio
3430 square inches / 26.25 square inches = 130.67 = 131

Then, multiply the # of Bricks to complete the patio by the amount that 1 brick costs:

131 * $0.59 = $77.29

It will take $77.29 to complete the Patio with bricks.

The # of Pavers to complete the Patio:

Patio's Area / the Area of 1 Paver = # of Pavers to complete the Patio
3430 square inches / 70.56 square inches = 48.6 = 49

Then, multiply the # of Pavers to complete the patio by the amount that 1 Paver costs:

49 * $1.88 = $92.12

Cost of Bricks to complete Patio = $77.29
Cost of Pavers to complete Patio = $92.12

To conclude, Bricks would cost less by $14.83.

What is the sum of f and g? f(x) =10-2x g(x)=7x+5A. (F+g)(x)=5+5x
B. (F+g)(x)=5+9x
C. (F+g)(x)=15+5x
D. (F+g)(x)=15+9x

Answers

Answer:

Step-by-step explanation:

To find the sum of f and g then add the expressions f(x) and g(x).

f(x) + g(x)

10-2x + 7x+5

10+5x+5

15+5x

This means that (F+g)(x) = 15+5x.

How do you multiply 3 different numbers?3.2 x 2.8 x 6.1 =
