Answers

Answer 1
I got B hopefully this works
Answer 2

Answer:

B; x = 8

Step-by-step explanation:

I think I understand what the picture is saying. So,

On the left hand side, the x's and +1's represent the following expression:

\(2x +5\).

On the right hand side, the x's and -1's represent the following expression:

\(3x -3\).

Put these two together and you get the following equation:

\(2x +5\) = \(3x -3\)

First, Solve for x:

8 = x

So, when solving the equation, x is equal to 8

Use a number line to order the numbers from least to greatest.

Use a number line to order the numbers from least to greatest.

Answers

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

9/4=2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?

Answers

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

We know that the circumference of a circle is given by:

C = 2πr

where C is the circumference and r is the radius of the circle.

In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:

18 = 2πr

Solving for r, we get:

r = 9/π ≈ 2.864 feet

Now we can use the formula for the area of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(2.864 ft)^2 ≈ 25.85 ft^2

Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Answer:

Step-by-step explanation:

 Short answer: How many digits are repeated? 2, exactly (1 and 5). So 2 digits, you have 99. If you have one digit repeated (like 0.3333...) then its 9. So, because of its 99. The answer is 15/99. Try to get what I mean.  Long answer: 0.151515151515.... x = 0.151515151515... 100x = 15.1515151515.....                         (to get this equation you multiply the above by 100) Based on the red above, use elimination. 99x = 15                    (solve for x) x = 15/99

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

Amber and Jessica go out for lunch. Amber’s lunch costs $11.70, and she tips 18%. Jessica’s lunch costs $12.30, and she tips 15%. Complete a true statement.
jessica paid [ 0.29 / 0.32 / 0.55 ] , [ more/ less ] than amber at lunch

Answers

Jessica paid more than Amber at lunch.

To find out, we first need to calculate the amount of tip each person left:

Amber's tip = 11.70 x 0.18 = $2.11

Jessica's tip = 12.30 x 0.15 = $1.85

Then we add the cost of the lunch and the tip for each person:

Amber's total cost = 11.70 + 2.11 = $13.81

Jessica's total cost = 12.30 + 1.85 = $14.15

So Jessica paid $0.34 more than Amber for lunch.

Question 1
Mr Brown has several models of famous people that each weigh the same. He decides to add in some new models that are of different weights to his old ones. In Room Number One, there are five old models along with a new model that weighs 240kg.
In Room Number Two, there are 3 old models along with a new model that weighs 510kg.

THE TOTAL WEIGHT OF THE MODELS IN ROOM ONE IS EXACTLY THE SAME AS THE TOTAL WEIGHT OF THE MODELS IN ROOM TWO.
What is the weight of an old model?

Answers

Answer:

135kg

Step-by-step explanation:

In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510.

the equation will be as: 5x + 240 = 3x + 510

move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240

which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

Part C The side length of cube B is 3 inches.

Part D The volume of cube B is 3 inches x 3 inches x 3 inches = 27 cubic inches. To fill cube B with cubes identical to cube A, you need 27 cubes of 1 cubic inch each. This is because 27 cubic inches / 1 cubic inch = 27.

Step-by-step explanation:

New bag of food will last until 2 1/2 weeks.

What is Proportion?

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p : q = r : s or p/q = r/s

Given that,

Amount of food fed to Great Dane by Deon in 1 week = 62 cups

He has a new bag with 160 cups of dog food.

He needs this food to last up to 2 1/2 or 2.5 weeks.

We have,

Amount of food needed in 1 week = 62 cups

Let Amount of food needed in 2.5 weeks = x cups

Ratio of 1 week to 62 cups and 2.5 weeks to x cups will be equal.

So using proportional concept, we can write this as,

1 / 62 = 2.5 / x

We have to find the value of x.

Doing the cross multiplication,

x = 2.5 × 62 = 155 cups

So the amount of food needed in 2.5 weeks = 155 cups.

But he has a new bag with 160 cups which is more than enough for 2.5 weeks, since only 155 cups is needed for 2.5 weeks.

Hence the new bag of food will last until 2 1/2 weeks.
