Min Jee wants to build a small patio using either brick or paver stones.
Anvisha [2.4K]
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 equation of this circle in standard form M(2,4) N(9,4) these are coordinates across the diameter of the circle?
igomit [66]
The standard form is

(x-xo)² + (y-yo)² = r²

Where xo,yo is the center of the circumference
and r is the radius.

We find the distance between the points to determine the <span>diameter

d=sqrt ((9-2)</span>² + (4-4)²<span>) = sqrt (49) = 7

The radius of the circumference is d/2 = 7/2 = 3.5

And we can see that those points are at the same coordinate y = 4 

The center is given then by , x = (9+2)/2 = 5.5
                                              y = (4+4)/2 = 4

The equation results

(x-5.5)</span>² + (y-4)² = (3.5)²<span>

</span>
