Explanation:
Extend the side that's 9.5 meters long out to the left so that you form a trapezoid on top and a rectangle underneath. The side we extended is now 5+9.5 = 14.5 meters long.
Let
A = area of the trapezoid up topB = area of the rectangle underneathThe goal is to find A+B
The trapezoid has the parallel sides of 14.5 and 10 meters. The height of the trapezoid is 28-20 = 8 meters. So we can say
Area of trapezoid = height*(base1+base2)/2
A = h*(b1+b2)/2
A = 8*(14.5+10)/2
A = 98
The rectangle has area of B = length*width = 5*20 = 100 square meters
Therefore,
total area = A+B = 98+100 = 198 square meters.

From as I can see. You need to do a long division on 76 and 9 and then if you got the answer subtract the answer with the girls surveyed and you'll get the answer and multiply the answer with the boys surveyed and then add all the answers together. Hoped this help!!! :)

Answers
Answer:
this is algebra remember algebra rules and thing really hard
Step-by-step explanation:
The formula for the height of the trapezoid will be h = 2A/(c+ d).
What is surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.
Given a trapezoid with side lengths c and d and perpendicular distance as h
So, the area formula will be
A = (1/2)h(c + d)
Multiply both sides by 2
2A = h (c + d)
Divide by c + d into both sides
2A/(c + d) = h
Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

What are the steps to finding areas?
Trapezoid:
Rectangle:
Circle:
Triangle:
Answers
Answer:
Trapezoid: So basically to find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
Rectangle: To find the area of a rectangle, multiply the length by the width. The formula is: A = L * W where A is the area, L is the length, W is the width, and * means multiply.
Circle: The area of a circle is pi times the radius squared (A = π r²).
Triangle: To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles.

Sara’s boss informed her she is getting a 5% raise. She currently makes $22 per hour. What is her new hourly wage?
Use your plan of multiplying 5100 and $22. What is the amount of Sara's raise?
Answers
Answer:
Her new hourly wage will be $23.10
Step-by-step explanation:
First, let's find out how much her raise is in dollars.
0.05 x 22 = 1.10
Then, let's add that to her current wage.
1.10 + 22.00 = $23.10
Hope this helps! Have a great Monday!
Answer:
Her new hourly wage will be $23.10
Step-by-step explanation:
5/100 * 22= 1.1
1.1 + 22= 23.1
$23.10
In a garden, 2/3 of the flowers are roses. Of the roses in the garden, 5/12 are yellow and the rest are red. What fraction of the flowers are red roses?
Answers
because 5/12 are yellow, the rest would be red. so 7/12. but total roses are only 2/3 of the whole garden.
tip: when you see "of" in a fraction problem, it means you can multiply them.
so, 7/12 OF 2/3 is just (7/12) * (2/3).
multiplying straight across and simplifying will get you to 7/18!

Look at the rectangle and the square:
A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.
Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.
Answers
Answer:
False
Step-by-step explanation:
Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:
[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]
We can do the same for the square in which ON = 6 because it's a square:
[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]
Now let's compare them:
8.5 X 2 = 17 so OM X 2 is not equal to SQ
The sentence is false.

The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.
A graph shows the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.

Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.
Answers
Answer:Part A:8 Part B:$1
Step-by-step explanation:
Part A: 7 dollars
- The graph shows that 2 bushels is 14 dollars, because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.
- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.
- 7 can be known as the slope and rate of change.
Part B:2 dollars
- The years before show 2 bushes was 10 dollars
-so you would divide 10 by two you would get five To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.
-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

second option: 32.8 m, 48.2 m, 81.1 m
Step-by-step explanation:
20.2 m + 20.4 m = 40.6 m. which is bigger than 20.6 m. so yes
32.8 m + 48.2 m = 81 m. which is smaller than 81.1 m. so no
12.8 m + 25.7 m = 38.5 m. which is bigger than 35.9 m. so yes
35.6 m + 49.9 m = 85.5 m. which is bigger than 83.2 m. so yes
