Select the triangle that is similar to AABC.

Answers

Your correct answer is letter b

The Triangle MNP in which m∠M = 15  and m∠N = 135 is similar to triangle ABC.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Triangle ABC has the following angle measures:

m∠A = 15° and m∠B = 120°.

We know that the addition of the angles of a triangle makes 180°, therefore:

m∠A + m∠B + m∠C = 180°

Replacing with data and solving for x:

15 + 120 + x = 180

x = 180 - 135

x = 45°

The Triangle MNP in which m∠M = 15  and m∠N = 135 is similar to triangle ABC.

The list shows the number of minutes that eight students spent on math homework last week. 22, 14, 24, 20, 36, 28, 43, 35What is the mean absolute deviation of the numbers

Answers

Given:

The data values are:

22, 14, 24, 20, 36, 28, 43, 35

To find:

The mean absolute deviation of the given numbers.

Solution:

We have,

22, 14, 24, 20, 36, 28, 43, 35

The measure of the given numbers is:

[tex]\overline{x}=\dfrac{\sum_{i=1}^{n} x_i}{n}[/tex]

Where, [tex]x_i[/tex] represents the observations and n is the number of observation.

So, the mean value of the given data set is:

[tex]\overline{x}=\dfrac{22+14+24+20+36+28+43+35}{8}[/tex]

[tex]\overline{x}=\dfrac{222}{8}[/tex]

[tex]\overline{x}=27.75[/tex]

The formula for is mean absolute deviation is:

[tex]M.A.D.=\dfrac{1}{n}\sum_{i=1}^{n}|x_i-\overline{x}|[/tex]

The mean absolute deviation of the given numbers is:

[tex]M.A.D.=\dfrac{1}{8}[|22-27.75|+|14-27.75|+|24-27.75|+|20-27.75|+|36-27.75|+|28-27.75|+|43-27.75|+|35-27.75|][/tex]

[tex]M.A.D.=\dfrac{1}{8}[5.75+13.75+3.75+7.75+8.25+0.25+15.25+7.25][/tex]

[tex]M.A.D.=\dfrac{1}{8}[62][/tex]

[tex]M.A.D.=7.75[/tex]

Therefore, the mean absolute deviation of the given numbers is 7.75.

Bill buys 3 apples for
$1.47. How much would 10
apples cost Bill?

Answers

Answer:

$4.90

Step-by-step explanation:

bc math

Answer:

$4.90

Step-by-step explanation:

You could find this in the ratio method.

3 apples : $1.47

10 apples : x

( We have to find the value of x. This is the cost of 10 apples)

Cross Multiply both the ratios.

3x = 1.47 × 10

3x = 14.7

Bring 3 to the other side, making is being divided upon.

x = [tex]\frac{14.7}{3}[/tex]

x = 4.9

∴ 10 apples cost $4.90
