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
⦁ Leo designs a stand for the new statue on display at the local library. The stand is in the shape of a right trapezoidal prism. The base of the prism has an area of 3 ft2, and the prism stands 3.2 feet high. As Leo paints the stand, he calculates the surface area of the stand to be 35 ft2.
⦁ Leo is asked to purchase roping that will be used to close off the area around the statue. He purchases a length that is five times the perimeter of the stand in roping.
⦁ How much roping does he purchase?
⦁ Leo plans to add gold leaf to the sides of the stand but not to the two bases.
⦁ What percent of the area of the stand will have gold leaf? Round your answer to the nearest whole number.
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%.
Number of ropes and Percent of stand areaGiven:
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%.

percent discount
A $37.50 dress is on sale for $26.25.
A.20%
B.25%
C.30%
D.35%
E.40%
F.45%
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.
An electrician charges a flat fee for each job plus an hourly rate . He charged one customer $90 for a job that took him 3 hours . He charged another customer $150 for a job that took him 8 hours . Which equation models the relationship?.
Answer:
let x equal the service charge.
let y equal the per hour charge.
for the job that cost 450, the equation is 450 = x + 6y
for the job that cost 330, the equation is 330 = x + 4y
these two equations needs to be solved simultaneously.
subtract the second equation from the firs to get 120 = 2y
solve for y to get y = 60.
in the first equation, replace y with 60 to get 450 = x + 6*60.
simplify to get 450 = x + 360.
subtract 360 from both sides of the equation to get 90 = x.
it appears that the service charge is equal to 90 and the per hour charge is equal to 60.
for the job that cost 450, the equation becomes 450 = 90 + 6*60 = 90 + 360 = 450.
for the job that cost 330, the equation becomes 330 = 90 + 4*60 = 90 + 240 = 330.
the numbers check out.
the service charge is 90.
the per hour charge is 60.
i believe your solution is that the electrician charges a flat fee of 90 plus an hourly fee of 60 for a service call.
