Answer:

Twelve tickets cost $30.00.

Each additional ticket costs $2.50.

The table is a partial representation.

Answer:

A C D

Step-by-step explanation:

Answer:

1.  ∠9 = 115°

2.  ∠10 = 65°

3.  ∠8 = 70°

4.  ∠3 = 70°

5. ∠4 = 110°

6. ∠11 = 70°

7. ∠5 = 65°

8. ∠14 = 115°

Step-by-step explanation:

Given that, two parallel lines and two transversal lines.

also given that, ∠1 = 115°   &    ∠12 = 110°

We know that, straight angle  = 180°

∠1 + ∠2 = 180°

∠2 = 180 - 115

∠2 = 65°

∠2 & ∠5 are vertical angles. So, they are same

∠2 = ∠5

∠5 = 65°

Similarly, ∠1 = ∠6 (vertical angles)

∠6 = 110°

Now given that, ∠12 = 110°

∠11 + ∠12 = 180°

∠11  = 180 -110

∠11 = 70°

∠11  &  ∠16 are vertical angles.

∠11  = 16

∠16 = 70°

∠12   =   ∠15  (vertical angle)

∠15  = 110°

∠4  & 12 are Corresponding Angles

∠12  = ∠4

∠4 = 110°

∠3 = 180 - ∠4 = 180 - 110

∠3 = 70°

∠7 = ∠4   (vertical angle)

∠7 = 110°

∠3 = ∠8 (vertical angle)

∠8 = 70°

∠1 = ∠9    (Corresponding Angles )

∠9 = 115°

∠10 = ∠2  (Corresponding Angles )

∠10 = 65°

∠13 = ∠10  (vertical angle)

∠13 = 65°

∠14 = ∠9  (vertical angle)

∠14 = 115°

9.  ∠7 and ∠2  no relation between them.

10. ∠6 and ∠14  are corresponding angles.

11. ∠13 and ∠12 no relation.

12. ∠7 and ∠11 are Consecutive Interior Angles

13.  ∠1 and ∠8 no relation.

Numbers with factors of 9:

18, 27, 36, 45, 54, 63, 72, 81

18, 36, 54 and 72 may have factors of 2, but the other do not.

This means that not all numbers with 9 as a factor will also have 2 as a factor.

To do his work that he didn't want to do.

DaMontre practiced for 60 minutes after taking a total of 1,870 shots, with an initial 70 shots before practice and 30 shots per minute during practice.

The question asks how long DaMontre practiced basketball if he took a total of 1,870 shots, with a pre-practice session of 70 shots, and during practice, he takes 30 shots a minute.

Step-by-step solution:

First, subtract the extra shots DaMontre took before practice from the total number of shots to find out how many shots were taken during practice. So, 1,870 - 70 = 1,800 shots during practice.

Thus, DaMontre practiced for 60 minutes, which is the answer to the question.

Answer:

you would - 1 to -7 and get -8 then divide -8 by -2 than it would be 4

Step-by-step explanation:

I like my equations to have the variable before the constant.

2g+1=-7

Subtract 1 from the left side. Remember, whatever you do on one side, you MUST do it on the other.

2g=-8

Divide 2 from BOTH sides.

The equation to determine the weight of each of Carl's checked bags is 2w + 4 = 35. After solving, we find that each checked bag weighs 15.5 kg.

To solve the problem regarding Carl's baggage weight, we set up an equation. Carl has two checked bags of equal weight, let's call the weight of each bag w kilograms. He also has a backpack weighing 4 kg. According to the problem, the total weight of all his baggage is 35 kg. We can represent this situation with the following equation:

2w + 4 = 35

This equation adds the weight of the two checked bags (2w since there are two of them and they are equal in weight) and the 4 kg backpack to get the total weight of 35 kg. To find the weight of each checked bag, we can simply subtract the weight of the backpack from the total weight and then divide by two:

Therefore, the weight of each of Carl's checked bags is 15.5 kg.

The standard form of a linear equation in general is given by:

[tex]ax+by=c[/tex]

Now we are given the equation :

[tex]4x-\frac{2}{3}y=8[/tex]

In order to convert this into standard equation, we have to eliminate the 3 in the second term on the left side of equation.

Here 3 is in division ,so we have to perform opposite operation of division that is multiplication.

So multiplying both sides by 3 , we have

[tex]12x-2y=24[/tex]

So that means option A.Multiply both sides of the equation by 3. The standard form of the equation is 12x – 2y = 24. is the correct advice given by Sofiya.

Answer: There is 12% of last semester's college costs was spent on books.

Step-by-step explanation:

Since we have given that

Amount spent at her community college = $2300

Amount spent of that on books = $276

We need to find the percent of last semester's college costs was spent on books is given by

[tex]\dfrac{276}{2300}\times 100\\\\=\dfrac{27600}{23}\\\\=12\%[/tex]

Hence, there is 12% of last semester's college costs was spent on books.

The student spent 12% of last semester's college costs on books.

To find the percentage of last semester's college costs that was spent on books, you can use the following formula:

Percentage = (Part / Whole) * 100

In this case:

The "Part" is the amount spent on books, which is $276.

The "Whole" is the total college cost for last semester, which is $2300.

Percentage = ($276 / $2300) * 100

Percentage = (0.12) * 100

Percentage = 12%

So, the student spent 12% of last semester's college costs on books.

The answer is D the last graph.

The required graph shows a dilation in graph D. Option D is correct.

Following the given case, 4 graphs are shown we have to determine the graph showing the dilation of concentric triangles.

Dilation of a triangle refers to the transformation that changes the size of the triangle while preserving its shape. It involves scaling the triangle by a factor, either enlarging or reducing its dimensions. The dilation is centered at a fixed point called the center of dilation.

While going through the figure, graphs A, B, and C are none dilated triangles because the triangles show dissimilarities. But D shows the dilation of the triangle because the two triangles are similar.

Thus, the required graph shows a dilation in graph D. Option D is correct.

To determine the fraction of the floor covered, we multiply the fraction of the length covered (3/4) by the fraction of the width covered (3/5), resulting in a covered area of 9/20 of the floor space.

To find the fraction of the floor that has been covered by tile, we need to multiply the fraction of the length covered by the fraction of the width covered. If an area of 3/4 of the length and 3/5 of the width is covered, then we perform the multiplication: (3/4) x (3/5) = 9/20.

This means that the fraction of the floor covered with tile is 9/20. This fraction represents the percentage of the entire floor that is tiled, which in this case indicates that less than half of the room is covered because 9/20 is less than 1/2.

The inequality based on the information will be 0.8x + 8 ≤ 15.

Let x be the number of rides you can go on.

The total amount of money you will spend on rides is 0.8x dollars.

The total amount of money you will spend on admission, lunch, and a snack is $4 + $3 + $1 = $8.

The total amount of money you have to spend is $15.
