Answer:

C) 12.2 cm

Step-by-step explanation:

To find the area of a square, you multiply length and width, which for a square, are the same. So to find the length of one of its sides, you have to take the square root of the area.

$L^{2} = 150\\\\L=\sqrt{150} \\L= 12.2\\$

Step-by-step explanation:

8a+a−3+6a−2a−3

=8a+a+−3+6a+−2a+−3

Combine the like terms:

=8a+a+−3+6a+−2a+−3

=(8a+a+6a+−2a)+(−3+−3)

=13a+−6

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.

John has decided to prepare an old field for his son's new horse. the length of the field is 10 meters less than 4 times its wid

tatuchka [14]

Answer: The total money invested in the field will be $1,623.80

Step-by-step explanation:

step 1

Find the dimensions of the field

Let

x -----> the length of the field

y -----> the width of the field

p=2(x+y)

p(4.80)=1,584

p=330m

we know that

The perimeter of the field is equal to

330=2(x+y)----> equation A

x=4y-10 ------> equation B

substitute equation B in equation A and solve for y

330=2(4y-10+y)

165=(5y-10)

5y=165+10

y+35

Find the value of x

x=4(35)-10+130

therefore

The length of the field is 130 meters and the width of the field is 35 meters

step 2

Find the area of the field

The area of the field is

A=xy

substitute

A=(130)(35)=4,550m2

step 3

Find the number of bags of seed

Divide the area by 460

4,550/460=9.89 bags

Round up to the nearest whole number

9.89 bags=10 bags

step 4

Find the cost of the seed

(10 )(3.98)=$19.8

step 5

Find the total money invested in the field

1,584+$39.8=$1,623.80
