A trapezoid was broken into two congruent triangles and a rectangle. A trapezoid is broken into 2 triangles and 1 rectangle. The

Naddika [18.5K]

complete question:

The picture below is the complete question.

Answer:

base of the triangles = 3 cm

Step-by-step explanation:

The trapezoid was broken into 2 congruent triangles and a rectangle. The 2 triangle have a height of 12 cm . The rectangle has a height of 12 cm and width of 14 cm .

The base length of the triangle can be computed as follows.

Note a congruent triangle have exactly the same three sides and exactly the same three angles.

area of a triangle = 1/2 × base × height

From the area of the trapezoid one can calculate the sides of the triangle.

area of the trapezoid = 1/2 × (a + b)h

where

a = top side

b = base side

h = height

area of the trapezoid = 1/2 × (a + b)h

area of the trapezoid = 1/2 × (14 + 20)12

area of the trapezoid = 1/2 × 34 × 12

area of the trapezoid = 34 × 6

area of the trapezoid = 204 cm²

204 = area of the triangles + area of the rectangle

204 =2 (1/2bh) + lw

where

b = base of triangle

h = height of triangle

l = length of rectangle

w = width of rectangle

204 = bh + (14 × 12)

204 = 12b + 168

12b = 204 - 168

12b = 36

divide both sides by 12

b = 36/12

b = 3 cm

base of the triangles = 3 cm

Dilate line f by a scale factor of 2 with the center of dilation at the origin to create line f'. Where are points A' and B' loc

miss Akunina [59]

Answer:

Option (1).

Step-by-step explanation:

Given question is incomplete: find the complete question in the attachment.

From the given figure, coordinates of the points A and B are (0, 2) and (2, 0) respectively.

Slope of line AB = $\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$

$m_{1}=\frac{2-0}{0-2}=-1$

When these points are dilated by a scale factor = 2, about the origin

Rule for the dilation → (x, y) → (kx, ky)

Where k = scale factor

Coordinates of the points A' and B' will be (0, 4) and (4, 0)

Slope of the line A'B' = $\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$

$m_{2}=\frac{4-0}{0-4}=-1$

Since $m_{1}=m_{2}$ , both the lines AB and A'B' will be parallel.

Therefore, option (1) will be the answer.

Since all sectors have the same area, the spinner is equaly likely to land on each of them. There are:

3 yellow sectors
3 red sectors
4 green sectors
1 blue sector

Obviously, this implies that there are 11 sectors in total.

So, the spinner will land on a certain color with probability

$p=\dfrac{\text{\# of sectors for that color}}{\text{11}}$

Use this formula to deduce the probability of green.

Finally, you can multiply the probability of red by 11 to get the expected number of reds in 11 spins.

Identify the coordinates of four points on the line with each given slope and y-intercept. slope = 2/3 and y-intercept = -5.....

alexdok [17]

The linear equation is y = (2/3)*x - 5, and the 4 points in the graph are:

{ (-1, -17/3), (0, -5), (1, -13/3), (2, -11/3)}

<h3>How to identify the points on the line?</h3>

A linear equation written in the slope-intercept form is:

y = a*x + b

Where a is the slope and b is the y-intercept.

In this case, we have:

a = 2/3

b = -5

So our line is:

y = (2/3)*x - 5

To find the points, we need to evaluate the line in 4 different values of x.

We will use: x = -1, 0, 1, 2.

for x = -1 we have:

y = (2/3)*-1 - 5 = -2/3 - 5 = -17/3

So this gives the point (-1, -17/3).

for x = 0 we have:

y = (2/3)*0 - 5 = -5

So this gives the point (0, -5).

for x = 1 we have:

y = (2/3)*1 - 5 = -13/3

So this gives the point (1, -13/3).

for x = 2 we have:

y = (2/3)*2 - 5 = 4/3 - 15/3 = -11/3

So this gives the point (2, -11/3).

Then the 4 points are:

{ (-1, -17/3), (0, -5), (1, -13/3), (2, -11/3)}
