Find area of rectangle
find are a of triangle
rectanglearea-trialgnearea=areaofshadedreigon

rectanglearea=legnth times wdith
trianglearea=1/2 times base tiems height

rectangle is 13 by 8
area=13*8=104

trialgle area=
we need to find base
13-4-4=5
base=5
height=6
area=1/2 times 5 times 6=15

rectangle-traingle=104-15=89 m^2

julia-pushkina [17]

Hey there! I'm happy to help!

Here's how to find the distance between any two points.

Find the difference of the x values.

-5-7=-12

Square it.

-12²=144

Find the difference of the y values.

6-3=3

Square that.

3²=9

Add the two numbers we got.

144+9=153

√153≈ 12.37.

Have a wonderful day! :D

Danielle estimates that she well spend $250 on new summwe colthes. She acually spent $350. What is the percent error? Round to t

EleoNora [17]

Answer:

The percent error is 40%

Step-by-step explanation:

To calculate the error percentage we have to divide the final amount over the initial amount

350 / 250 = 1.4

then we subtract 1 since this represents the estimated value

1.4 - 1 = 0.4

this is the error factor we have, to express it as a percentage we simply multiply by 100

0.4 * 100 = 40%

The percent error is 40%

The number of lines and triangles illustrates combination

36 lines can be drawn to join the nine points
84 triangles can be drawn using the nine points

<h3>The number of lines that can be drawn</h3>

The given parameters are:

Total points, n = 9

Total points on each line, r = 2

The number of lines that can be drawn is then calculated using the following combination formula

Lines = nCr

This gives

Lines = 9C2

Evaluate the combination expression

Lines = 36

Hence, 36 lines can be drawn to join the nine points

<h3>The number of triangles that can be drawn</h3>

The given parameters are:

Total points, n = 9

Total points on each triangle, r = 3

The number of triangles that can be drawn is then calculated using the following combination formula

Triangles = nCr

This gives

Triangles = 9C3

Evaluate the combination expression

Triangles = 84

Hence, 84 triangles can be drawn using the nine points
