Find the area of trapezoids
Answer:
Area is 10.5
Step-by-step explanation:
We can use the trapezoid formula of
[tex]A = \frac{a+b}{2}h[/tex]
A = (2 + 5) / 2 * 3 = 3.5 * 3 = 10.5
or break it into a rectangle and a triangle (natural split by y axis).
A = 2 * 3 + 3 * 3 / 2 = 6 + 9 / 2 = 6 + 4.5 = 10.5
Answer:
10.5 units²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = OS = 3 , b₁ = OC = 5 , b₂ = SK = 2 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²

Graph a line with a slope of 3/4 that contains the point (2,-3).
Answer:
Start at the y-intercept (0, -4.5) and then use rise over run (Up 3 and right 4)
Step-by-step explanation:
y - y1 = m(x - x1)
y + 3 = 3/4(x - 2)
y + 3 = 3/4x - 3/2
y = 3/4x - 9/2
On number line below, length AB =? A16 B45
Answer:29
Step-by-step explanation:
d[AB]=|45-16|=29
A number line is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
The length AB is 29.
AB = 29 is our answer.
What is a number line?It is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
We have,
A is at point 16.
B is at point 45.
Now,
The distance between A and B.
= B - A
= 45 - 16
= 29
Thus,
The length AB is 29.
AB = 29 is our answer.

ILL BRAINLIEST YOU IF YOU GET IT RIGHT
Can you help me match each figure with the appropriate angle pair relationship
Answer:
co interior angle plz take my and
Answer:
1) Alternate exterior
2) alternate interior
3) consecutive interior angles
Alright so here’s a trick
Alternate already means different sides so look for that.
Interior angles are all the angles inside the two parllel lines.
Exterior angles are all angles out side the two parralel lines.
No matter what if its alternative interior or exterior, it should make a perfect
“/“ or back slash.
Consecutive is on the same side.
Corresponing is also on the same side but it has 1 exterior and 1 interior

What’s the area of this polygon answer ASAP my teacher died
Answer:
Break it into 2 sections: 18 by 3 and 6 by 20
area = 54 + 120
= 174 (answer is A.)
Step-by-step explanation:
9514 1404 393
Answer:
A. 174
Step-by-step explanation:
Use your number sense. The area can be no larger than the rectangle that is 20 high and 9 wide. That rectangle's area is ...
A = LW = (20)(9) = 180
The only answer choice smaller than 180 is ...
A. 174 . . . . . square units
__
If you want to compute it exactly, you can make note of the size of the empty space at the upper left corner. That space is 20-18 = 2 units high and 9-6 = 3 units wide. Its area is A = LW = (3)(2) = 6 square units. When that empty space is subtracted from the overall rectangle area, the result is ...
180 square units - 6 square units = 174 square units.

What is the unit rate for the proportional relationship represented by the equation y=4/5x
Answer choices:
A:4/5
B:-2
C:4
D:5
Answer:
A: 4/5
Step-by-step explanation:

So in y = 4/5x, 4/5 is the constant of proportionality/unit rate for the proportional relationship.
The 4/5 is the constant of proportionality/unit rate for the proportional relationship.
We have given that,
the unit rate for the proportional relationship is represented by the equation y=4/5x.
We have to determine the unit rate
What is the equation of proportionality?The equation for proportionality is y = kx, where k is the constant of proportionality.

Slope- intercept equation from a graph
Find the equation of the line
We can find the slope using any two points on the line. Readily identifiable are the points (2, 0) and (0, 3), from which we can find the slope:
[tex]\text{slope} = m=\frac{y_2-y_1}{x_2-x_1} \\ m = \frac{3-0}{0-2} = -\frac{3}{2}.[/tex]
The y-intercept is the y value when x = 0, which we already know is 3. So, the slope-intercept equation of this line is:
[tex]y=-\frac{3}{2}x+3.[/tex]
