What is the length of Line segment A J if Line segment A B is parallel to lines segment J K?

8 in.

8.75 in.

10.25 in.

14 in.

Answers

Answer 1

Answer:

8.75 in.

Step-by-step explanation:

See attachment for the figure.

As you can see, ∆ HBA & ∆HKJ are similar,

HB/HA = HK/HJ

3/5.25 = 8/HJ

3HJ/5.25 = 8

3HJ = 42

HJ = 14 in.

AJ = 14 - 5.25

AJ = 8.75 in.

Therefore, the length of Line segment AJ is 8.75 in.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

The solution to the product of the fractions is 7/4

How to evaluate the product of the fractions

From the question, we have the following parameters that can be used in our computation:

7/12 * 3

Express 3 as 3/1

So, we have

7/12 * 3 = 7/12 * 3/1

Evaluate the products of 7 and 3

So, we have

7/12 * 3 = 21/12

Divide 21 and 12 by 3

7/12 * 3 = 7/4

Hence, the solution is 7/4

Line B

The upward sloping solid line crosses the y-axis at y=0 and has a rise of 1 for each run of 1 unit to the right. Its slope is 1/1 = 1, and its y-intercept is 0.

The equation for the boundary line can be written ...

help me pls: Select the fraction that is equivalent to two thirds.

a. 2/12
b. 4/12
c. 3/6
d. 8/12

Answers

Answer: D. 8/12

Step-by-step explanation:

8/12 is the equivalent fraction to 2/3 which we can see when the fraction is put into it's simplest form.

See here: In the fraction 8/12, there is an 8 as the numerator (top number) and a 12 as the denominator (bottom number). When we look at these, it is crucial to find the GCF (greatest common factor) so it can be put into simplest form. In this case, 8's factors are (1x8) and (2x4). 12's factors are (1x12), (2x6), and (3x4). Looking at these factors for both numbers, we can see that they both have a 2 and a 4. However, because the 4 is the greater number, it is our GCF. Now divide the numerator and the denominator by 4 to get 2/3

8/12 bc 2/3 if u multiply by 4 u get 2x4=8 and 3x4=12 so 8/12

Find the vertical distance between points X(−2,3) and Y(−2,114) .

Answers

Answer:

111

Step-by-step explanation:

114-3

Answer:

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.

In other words you get the basic idea, you can also just count, but whatever.

A theater company has raised $810.75 by selling 15 floor seat tickets. Each ticket costs the same.

Part A: Write an equation with a variable that can be solved to correctly find the price of each ticket. Explain how you created this equation. (5 points)

Part B: Solve your equation in Part A to find the price of each floor seat ticket. How do you know your solution is correct? (5 points)

Answers

Part A:
Let's assume the price of each floor seat ticket is represented by the variable 'x'.

Since the theater company has raised $810.75 by selling 15 floor seat tickets, we can create an equation using the concept of total revenue. The total revenue is calculated by multiplying the price of each ticket by the number of tickets sold.

Therefore, the equation can be written as:

15x = 810.75

In this equation, '15x' represents the total revenue from selling 15 tickets at the price of 'x' per ticket, and '810.75' represents the total amount of money raised.

Part B:
To solve the equation 15x = 810.75, we need to isolate the variable 'x' on one side of the equation.

Dividing both sides of the equation by 15, we have:

x = 810.75 / 15

Evaluating the division, we find:

x ≈ 54.05

Therefore, the price of each floor seat ticket is approximately $54.05.

To confirm the solution, we can substitute the value of 'x' back into the original equation:

15 * 54.05 ≈ 810.75

This equation holds true, as the left side is approximately equal to the right side. Hence, we can conclude that the solution is correct.

I hope this helps! :)

Part A: 15x= $810.75. Part B: x= $54.05

The total money earned from 15 tickets is $810.75.

Assume, the money earned from selling 1 ticket is $x.

Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75

Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.

Using the equation above,

15x= $810.75.

Dividing both sides by 15,

We get,

x= $54.05

Hence, $54.05 is the price of each ticket.
