Answer:

Total Area = 1200 in^2

Step-by-step explanation:

There is a triangle and a rectangle.

Arca Triangle: Area = 1/2 * Base* Height

Area = 1/2 * 40 in * 30 in = 600 in^2

Area Rectangle: Area = Length* Width

Area = 30 in * 20 in = 600 in^2

Total Area = Area Rect + Area Tri

Total Area = 600 in^2 + 600 in^2 = 1200 in^2

If the surface area of the stand to be 35 ft². The number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

Given:

Base area=3ft²

Height=3.2 feet

Surface area=35ft²

a. Number of ropes

Surface area=2×Base area×Base perimeter×Height

Base perimeter(BP):

35=2×3+BP×3.2

35=6+3.2BP

Collect like term

3.2BP=35-6

3.2BP=9

Divide both side by 3.2BP

BP=29/3.2

BP=9.0625ft

Number of ropes=5×9.0625ft

Nimber of ropes=45.3125ft

b. Percent of stand area:

Percent of stand area=(9.0625ft×3.2)÷35ft²

Percent of stand area=29ft²÷35ft²×100

Percent of stand area=82.857ft×100

Percent of stand area=83% (Approximately)

Therefore the number of ropes purchase is 45.3125ft and  Percent of stand area is 83%.

Answer: $7.60

Step-by-step explanation:

$4.56/12 is 0.38 cents (Cost of each orange)

so $0.38 x 20 is $7.60

Answer:

$7.6

Step-by-step explanation:

Cost of 12 oranges=$4.56

Cost of 1 Orange= $4.56/12=$0.38

Cost of 20 oranges =20 × Cost of 1 orange=20×$0.38=$7.6

Answer: I believe it should be [tex]\frac{1}{3}[/tex] for the final answer and here is how I would solve for this answer.

Step-by-step explanation:

You get [tex]\frac{1}{3}[/tex] because you can't simplify the fraction into a whole number. And if you need the decimal then you get 0.33333333 or 0.3 repeating.

Answer:

It will take both of the brick layers twelve and half days

6 Days

Step-by-step explanation:

First you must find the combined rate of work per day between the two bricklayers.

(100/10)+(100/15) = 16 2/3

For each day the two bricklayers complete 16 2/3 percent of the work. To find out the amount of days it take them to build the wall you divide 16 2/3 from 100

100/16 2/3 = 6

The amount of days it take the two bricklayers to build the wall together is 6.

Answer: Sqaure

Step-by-step explanation:

We obtain the figure by either plotting or finding the distances between the points:

[tex]\begin{aligned}&\text { Distance } b / w \quad A B =\sqrt{(1-7)^{2}+(3-(-3))^{2}}\\&=\sqrt{6^{2}+6^{2}}\\&A B=\sqrt{72} \text { units }\end{aligned}[/tex]

[tex]\text { Distance } b / w \quad BC =\sqrt{(7-1)^{2}+(-3-(-9))^{2}} \\BC=\sqrt{72} \text { units }[/tex]

[tex]\begin{aligned}\text { Distance } b / w \ C D &=\sqrt{(1-(-5))^{2}+(-9-(-3))^{2}} \\C D=\sqrt{72} \text { units }\end{aligned}[/tex]

[tex]$$ Distance $b/w \ A D=\sqrt{(1-(-5))^{2}+(3(-3))^{2}}$A D=\sqrt{72} \text { units }[/tex]

Since all the distances of the four sides are equal, we have to check if the shape is either a rhombus or a square by the measuring the length of the diagonals

[tex]\begin{aligned}A C &=\sqrt{(1-1)^{2}+(3-(-9))^{2}} \\&=\sqrt{12^{2}} \\A C &=12 \text { units } \\B D &=\sqrt{(7-(-5))^{2}+(-3-(-3))^{2}} \\&=\sqrt{12^{2}} \\A C &=12 \text { units }\end{aligned}[/tex]

The diagonals are also equal; therefore, the figure is a square

Answer:

(2.5, 0)

Step-by-step explanation:

The point in which a line crosses the x-axis is also known as the x- intercept. x-intercepts occur at y= 0, so let's substitute y= 0 into the equation and solve for x.

2x +y= 5

When y= 0,

2x +0= 5

2x= 5

Divide both sides by 2:

x= 2.5

Thus, the coordinate is (2.5, 0).

Answer:

C. 30%

Step-by-step explanation:

If you subtract 26.25 from $37.50, you're left with a difference of 11.25.

Given that your question has six possible answers, you can eliminate three of them considering 11.25 is somewhat close to 1/3 of 37.50.

After you've eliminated the first three options, you're left with 30%, 35%, and 40%.

You would get 28.125 by multiplying 11.25 by 2.5 (equal to 40%). So we know that 40% is NOT the solution.

You would get 33.75 by multiplying 11.25 by 3 (equivalent to 33.3 percent). So we know that 35% percent is NOT the solution because a figure less than 35 percent doesn't equal 37.5 percent.

Now that two of the three possible responses have been ruled out, you're left with only one correct answer, 30 percent.

Multiply 37.5 by 0.3 to double-check your work. You'd be left with 11.25, which is the same amount as when you subtracted the dress's price after the discount from the original dress's price.
