1.Choose the best description for ∠1 and ∠2 in the following figure.

2. Determine whether the angles are adjacent angles, a linear pair, or vertical angles. ​Some pairs of angles may have more than one relationship.

THE PICTURES ARE IN ORDER THE LAST TWO ARE FOR NUMBER 2

Answer:

66°

Step-by-step explanation:

Complementary angles are those that add up to 90 degrees. Since a and b are complementary, we can write:

∠a + ∠b = 90

We already know that ∠a = 24°, so we can plug this in:

24 + ∠b = 90

∠b = 90 - 24 = 66°

Thus, the answer is 66°.

Answer:

13.6

Step-by-step explanation:

The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor as follows:

dilation factor = A'Q/AQ

AQ = A'Q/dilation factor

Replacing with data:

AQ = 2.4/0.15 = 16

Then, the distance between points A and A' is

x = 16 - 2.4 = 13.6

The  distance between points A and A' is 13.6 units

Dilation is a way of changing the position of an image on an xy-plane.

The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor. Hence'

scale factor = A'Q'/AQ

Given the following

A'Q' = 2.4

Scale factor = 0.15

Substitute

AQ = 2.4/0.15

AQ = 16

x = 16 - 2.4

x = 13.6

Hence the  distance between points A and A' is 13.6 units

Answer:

C

Step-by-step explanation:

If  The probability of spinning a “1” is 0.25, then the probability of spinning 4 ones is:

0.25*0.25*0.25*0.25 = 0.25^4 ≈ 0.004

(the four events are independent)

The pointer landed on 1 each time, which probability is very low. So, we can conclude that the spinner is not fair.

15 is not a prime factor as it is divided by 1,3,5 and 15.

Additional information:

Prime numbers are those numbers which can only be divided by itself .for instance:1,2,3,5,7 ,11,13 etc.

Composite number s are those numbers which can be also divided by other numbers,For instance: 4,6,8,10 etc

im not sure but I think the answer is -4

Answer:

4

Step-by-step explanation:

Take away the negative signs:

-80/-20

80/20

Now, divide normally.

80 ÷ 20 = 4

Since a negative number divided by another negative number is positive, the quotient is still 4.

Therefore, the simplified fraction is 4.

142.4 cubic units is the correct answer

Step-by-step explanation:

right on edge

The volume of oblique cone, to the nearest tenth is,

⇒ 142.3 units³

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Since, WE know that,

Volume of oblique cone = (1/3) x π x r² x h

Given that,

Radius (r) = 4 units

Height (h) = 8.5 units

Thus:

Volume of oblique cone = (1/3) x π x 4² x 8.5

Volume of oblique cone = 1/3 × 3.14 × 16 × 8.5

Volume of oblique cone = 142.3 units³

Answer:

C

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Gradient=

[tex] \frac{y1 - y2}{x1 - x2} [/tex]

[tex]m = \frac{ - 12 - ( - 15)}{ - 5 - ( - 1)} \\ m = \frac{15 - 12}{1 - 5} \\ m = - \frac{3}{4} [/tex]

y= -¾x +c

To find c, substitute a coordinate.

When x= -1, y= -15

[tex] - 15 = - \frac{3}{4} ( - 1) + c \\ c = - 15 - \frac{3}{4} \\ c = - 15\frac{3}{4} [/tex]

Thus the equation of the graph is

[tex]y = - \frac{3}{4} x - 15 \frac{3}{4} [/tex]

Therefore the answer is C.

Answer:

-1.5

Step-by-step explanation:

4x - 36 = 36 + 52x

We can make this into another equation.

72 + 52x = 4x

4x - 52x = -48x

-48x = 72

48x = -72

x = -72/48 = -1.5

Pls do mark me as brainliest.Thanks! ;)

Answer:

x = - [tex]\frac{3}{2}[/tex] = - 1.5

Step-by-step explanation:

Given

4(x - 9) = 4(9 + 13x) ← distribute parenthesis on both sides

4x - 36 = 36 + 52x ( subtract 52x from both sides )

- 4x - 36 = 36 ( add 36 to both sides )

- 4x = 72 ( divide both sides by - 4 )

x = [tex]\frac{72}{-4}[/tex] = - [tex]\frac{3}{2}[/tex] = - 1.5

percentage change   ≈  140%

Step-by-step explanation:

There were 144 people in attendance at the school football game last Friday. This week there were 346 people in attendance at the school football game.What is the percent of change from last week to this week?Round your answer to the nearest whole number

To calculate the percentage change, we will follow the steps below:

First, we will find the difference(that is increase) between 144 and 346

Increase = New  number - Original number

             = 346 - 144

              = 202

Next is to divide the increase which is 202 by the original  number which is 144  and then multiply by 100

That is;

percentage change = increase ÷ original number × 100

                                   =202 / 144   ×  100

                                   ≈ 140    to the nearest  whole number

percentage change   ≈  140 %
