Answer: x=20

Step-by-step explanation:

3x+80=140

3x=60

x=20

Answer: Chris spent 60 tickets at the carnival.

Step-by-step explanation:

At the end of the night, both Chris and Keith had the same amount of tickets, so:

80 - x = 140 - 2x

Now, solve the equation. Start by bringing the -2x to the left side.

80 - x + 2x = 140

Bring the 80 to the right side so the variables are isolated.

-x + 2x = 60

Add like terms.

x = 60

Check the work.

Chris had 80, spent 60, so had 20 left. --> 80 - 60 = 20

Keith had 140, spent 120 (60 *2), so also had 20 left. --> 140 - 120 = 20

So, Chris spent 60 tickets at the carnival.

C. no, because all corresponding sides are not proportional.

Ratios must always remain proportional;

Whenever you multiply or divide one part by a number, you must do the same to the other part/s;

When it comes to division, you can divide by all common factors

Step-by-step explanation:

Answer: B: 24 feet.

Step-by-step explanation:

Let's assume that the length of the rectangular patio is "L" feet. Then, the width of the patio would be 3/4 L.

The area of a rectangle is given by the formula A = L x W, where A is the area, L is the length, and W is the width. We know that the area of the patio is 432 square feet. Substituting the values of L and W, we get:

432 = L x (3/4 L)

Multiplying both sides by 4/3, we get:

(4/3) x 432 = L^2

Simplifying, we get:

576 = L^2

Taking the square root of both sides, we get:

L = ±24

Since the length cannot be negative, the length of the patio is 24 feet.

Therefore, the correct answer is option B: 24 feet.

Answer: B the side length of XZ is 28

Step-by-step explanation:

to find the scale factor, one of the methods is to divide the side length of one triangle by the same side length of the other triangle.

for example with this problem, the length of XY is 42 while side length AB is 12. 42/12 is 3.5. we know that the side length that corresponds with XZ is 8 so multiply it by 3.5 to get the answer of 28.

Answer:

B

Step-by-step explanation:

Since we know that triangle XYZ is a scale model of ABC then if we find the amount XYZ is bigger then ABC then we can find the answer. Line CB is the corresponding line to ZY and ZY is 3.5x greater then CB. Apply the same logic to AC and we get 8*3.5=ZX 8*3.5=28 so ZX=28.

Step-by-step explanation:

The customer pays an amount of $26.74 for one pair of binoculars and one bird guide after the mark-up and 8.5% sales tax

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

According to the given, the required solution would be as:

Mark up for binoculars = 10 x 1.45 = 14.50

14.5 x 1.085 = 15.7325 in sales tax

The total cost per binocular is $15.73 ($).

Bird Guide Commission = 7 x 1.45 = 10.15

10.15 x 1.085 = 11.01275 Sales Tax

The total cost per Bird Guide is $11.11 ($).

The addition provides one of each.

⇒ 15.73 + 11.01 = 26.74

Thus, the customer pays an amount of $26.74 for one pair of binoculars and one bird guide after the mark-up and 8.5% sales tax

Answer:

400

Step-by-step explanation:

I divided 1600 by 4 which got me 400

Answer:

The large box weighs 61/4 Kg and the small box weighs 25/4 Kg

Step-by-step explanation:

Assume the large box is x and the small box is y

6x+2y=104, 3x+5y=77 therefore, 6x+2y=104, 6x+10y=154

8y=54 y=25/4 x=61/4

Answer:

The most appropriate measure of center for the given data set about 7th graders is the median (option B).

Step-by-step explanation:

The median is the middle value in a data set when the values are arranged in ascending or descending order. It is not affected by extreme values or outliers. There is an outlier in this case (180), which could alter the mean and represent the data inaccurately. The range does not give a measure of center but instead represents the spread of the data. The IQR is a valuable measure for understanding the spread of data and identifying potential outliers but is not suitable for describing the central tendency or average of the data.

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Step-by-step explanation:

Answer: 5

Step-by-step explanation:

The median is the middle number of a group of numbers. So, to find the median, first, find out how many numbers there are. You can do this on the dot plot by counting the dots. There are 9 dots.

To find the middle number when the total is odd, you can drop the number down to an even number that will divide in half (or divide the number by two). In this case, you can drop the number to 8 and divide by two. The answer to that is 4. Because there was an odd number of dots, you should use the 4th and then the 5th numbers to determine the middle number. We also count the 5th number because the total was odd. If the total is even, use only one number as the middle number.

Since the 4th and the 5th number are lined up on the 5, that is the median number.

(If you ever have to find two numbers that are not lined up on the same number, you have to add those two numbers and divide by 2 to find the median.)
