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.

Which of the following is an equation of the line through (3, -1) and (−2, 14)?
A) y = 1/3x - 2
B) y = -1/3x
C) y = 3x - 10
D) y = -3x + 8
the required equation of the line is y = -3x + 8. option D is correct.
Given that,
To determine an equation of the line through (3, -1) and (−2, 14).
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx, where x is in degrees.
What is simplification?The process in computation to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Slopes of the line can be given as,
m = [y₂ - y₁ ] / [x₂ - x₁]
for points, (3, -1) and (−2, 14)
m = 14 + 1 / -2 - 3
m = -15 / 5
m = -3
So, equation D contains the slope -3.
Thus, the required equation of the line is y = -3x + 8. option D is correct.

The measures of three line segments are given in each set.
Which set of line segments cannot form a triangle?
20.2 m, 20.4 m, 20.6 m
32.8 m, 48.2 m, 81.1 m
12.8 m, 25.7 m, 35.9 m
35.6 m, 49.9 m, 83.2 m
Answer:
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

70% of the 80 students in the sixth grade are taking Spanish. How many students are taking Spanish? Pick the model that represents the problem.
Can you combine 4x and 2x2. Explain why or why not.
A total of 76 students responded to a survey about transportation to school. Of the girls surveyed, 22 walk to school and 29 get a ride. Of the 25 boys surveyed, 9 get a ride to school. Construct a two-way frequency table to display the data. Drag the numbers into the boxes. Each number may be used once, more than once, or not at all.
Answers:
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!!! :)

What is the y-intercept?
What is the x-intercept?
What is the slope of the line?
Find an equation for this line.
Answer:
Step-by-step explanation:
The "y intercept" is the point at which the graph intercepts the y-axis. In this case that point is (0, 20).
The "x intercept" is the point at which the graph intercepts the x-axis. In this case that point is (5, 0).
The slope of the line is m = rise / run. Here the "rise" is actually a drop from y = 20 to y = 0, so "rise" = -20. The "run" is the increase from x = 0 to x = 5, which is 5. Thus, m = the slope = -20/5 = -4. The slope is m = -4.
Given that we know the slope, m, of this line (m = -4) and two points on the line (use (0, 20) ), we can write the equation of the line immediately in point-slope form y - k = m(x - h), which in this particular case is
y - 20 = m(x - 0), or
y - 20 = -4x
Alternatively, we could put this into standard form: 4x + y = 20, or into
slope-intercept form: y = -4x + 20

What are the steps to finding areas?
Trapezoid:
Rectangle:
Circle:
Triangle:
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.

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.
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.

Step-by-step explanation:
The ruler is split into 8 parts, and this point is 6/8 of the ruler, if you simplify that fraction you get 3/4.
Answer:
3/4 and 12/16
Step-by-step explanation:
If you see there are 8 ticks. So it will go 1/8 to 8/8 or 1. Then you see the arrow is at 6/8. So you divide both by 2 to get 3/4 and multiply by 2 to get 12/16.
