what is two numbers that add to 20 and the difference is 6

Answer:

6squared+6squared+12squared=216 then double 216 hope this is it!

Step-by-step explanation:

Answer:

b)  180 cm²

Step-by-step explanation:

find area of square = 6 x 6 = 36

find area of one triangle = 1/2(6)(12) = 3(12) = 36

There are 4 congruent triangles, so 36 x 4 = 144

36 + 144 = 180

Answer:

option b a circle with a radius of 21.0 CM

Answer:

Step-by-step explanation:

move the shape 1 square to the left and then move it one square up

The triangle after a translation 1 unit to the left and 1 unit up will have vertices at (2, 2), (-4, 4), and (-2, 0).

Translation is a rigid transformation that moves each point of a figure a certain distance in a specified direction. For this triangle, we will translate all its vertices 1 unit to the left and 1 unit up.

Impact on the Coordinates:

Let's consider each vertex of the triangle and apply the translation:

a) Vertex (3, 1):

After the translation, this point will move 1 unit to the left and 1 unit up. Therefore, the new coordinates will be (3 - 1, 1 + 1) = (2, 2).

b) Vertex (-3, 3):

This point will also move 1 unit to the left and 1 unit up. The updated coordinates will be (-3 - 1, 3 + 1) = (-4, 4).

c) Vertex (-1, -1):

Similarly, this point will undergo the translation, resulting in (-1 - 1, -1 + 1) = (-2, 0).

New Triangle:

Now, we have the new coordinates for the vertices after the translation:

Vertex 1: (2, 2)

Vertex 2: (-4, 4)

Vertex 3: (-2, 0)

The transformed triangle will have vertices at (2, 2), (-4, 4), and (-2, 0).

Step-by-step explanation:

Answer:

k = 24, y = 24x

Step-by-step explanation:

Given x and y are proportional then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition when y = 72, x = 3 , then

72 = 3k ( divide both sides by 3 )

k = 24

y = 24x ← equation of proportion

Answer:

x=1, y=4

Step-by-step explanation:

x+y=5 - (1)

y=3x + 1 (2)

Sub (2) into (1)

x + (3x +1)=5

4x=5-1

x=4 ÷4

=1

Sub x=1 into (2)

y=3(1)+1

= 4

Answer:

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30

Step-by-step explanation:

These are independent events.

The probability of rolling a 5 is 1/6.

The probability of spinning a 5 is 1/5.

The probability of rolling a 5 or spinning a 5 is 1/5+1/6=11/30 but you have to subtract 1/30 because you can roll a 5 and spin a 5 at the same time. Therefore 11/30-1/30=10/30=1/3.

There are 30 outcomes. Roll first then spin to get the following outcomes:

11,12,13,14,15,21,22,23,24,25,31,32,33,34,35,41,42,43,44,45,51,52,53,54,55,61,62,63,64,65

You want to roll a 5 OR spin a 5. How many combinations have a 5 ? 10 combinations have a 5.

(you don't count 55 twice) There are 10 combinations with a 5 out of a possible 30 combinations.

Another way of looking at the problem is the following:What is the probability of NOT rolling a 5 AND NOT spinning a 5 ?

The probability of not rolling a 5 AND not spinning a 5 is (5/6)*(4/5)=20/30. Therefore the probability of rolling a 5 or spinning a 5 is 1-20/30=10/30.

Answer:D

Step-by-step explanation:

Neither data set has suspected outliers response best describes outliers in the data sets.

Option A is correct.

The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), ​first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

According to question

Reading:

Median = [tex]\frac{7+12}{2}[/tex] = 9.5

[tex]Q_{1}[/tex] = 5 × 25% + 7 × 75% = 6.5

[tex]Q_{3}[/tex] = 14 × 25% + 12 × 75% = 12.5

IQR is the difference between Q3 and Q1

IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 12.5 - 6.5 = 6

[tex]Q_{1}[/tex] - 1.5 IQR = 6.5 - 1.5 × 6 = -2.5 < Min = 5

[tex]Q_{3}[/tex] + 1.5 IQR = 6.5 + 1.5 × 6 = 15.5 > Max = 15

So no outlier in reading

Video :

[tex]Q_{1}[/tex] = 7 × 75% + 4 × 25% = 6.25

[tex]Q_{3}[/tex] = 21 × 25% + 18 × 75% = 18.75

IQR is the difference between Q3 and Q1.

IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 18.75 - 6.25 = 12.5

[tex]Q_{1}[/tex] - 1.5 IQR = 6.25 - 1.5 × 12.5 = -12.5 < Min = 1

[tex]Q_{3}[/tex] + 1.5 IQR  = 18.75 + 1.5 × 12.5 = 37.5 > Max = 26

So no outlier in video

So neither data set has suspected outliers.

Option A is correct.

Answer:

up 2, right 3

Step-by-step explanation:

up 2, to the right 3.

The translation was 2 units right and 3 units up.

As per the given data:

We are given AB with the coordinates as, A(-3, -1) and B(2, 1).

After translation, AB becomes A'B' with A'(-1, 2) and B'(4, 4).

We can find out the translation by finding out the change in the corresponding coordinates.

For A to A':

Change in x coordinate = -1 - (-3) = -1 + 3 = 2

Change in y coordinate = 2 - (-1) = 2 + 1 = 3

Increase in x coordinate of 2 units = 2 units right.

Increase in y coordinate of 3 units = 3 units up

Hence, the translation was 2 units right and 3 units up.

Answer:

Options (B) and (E)

Step-by-step explanation:

Area of ΔABC = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                        = 42 in²

Area of trapezoid ADEC = [tex]\frac{1}{2}(b_1+b_2)h[/tex]

[Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides and 'h' is the height of the isosceles trapezoid given]

= [tex]\frac{1}{2}(10+14)(8)[/tex]

Area of the pentagon = Area of triangle ABC + Area of trapezoid ADEC

                                    = 42 + 96

Answer: a=101 b=79 c=83 d=97

Step-by-step explanation:

A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.

B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.

C: opposite angles are always the same so it would still be 83°.

D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.

Step-by-step explanation

I'm sorry but I have no time, can someone comment me and explain? Thank you :)

Answer: y = -1.4(2.1 - 4.2x)

Step-by-step explanation:

4.2x - 1.4y = 2.1

Firstly you should move 4.2x over (by subtraction) so the new equation is:

-1.4y = 2.1 - 4.2x

Then you want to multiply everything by -1.4 to take it away from the y side. This will bring you to:

y = -1.4(2.1 - 4.2x)

This can be simplified down to

y = -2.94 + 5.88x

or

5.88x -2.94 = y
