Which equation has a constant of proportionality equally to 2? PLS HELP I WILL MARK AS BRAINLIEST

Answers

Answer 1

Hello there!

A would be the correct answer since 10 divided by 5 equals 2 and so it would be 2x.

B is wrong since it has a constant of proportionality equal to 1.

C is wrong since it has a constant of proportionality equal to 1/2.

D is wrong since it has a constant of proportionality equal to 11.

Answer 2

Answer:

Step-by-step explanation:

The equation of proportional quantities is

y = kx ← k is the constant of proportionality

y = $\frac{10}{5}$ x = 2x ← with k = 2

y = $\frac{2}{2}$ x = x ← with k = 1

y = $\frac{2}{4}$ x = $\frac{1}{2}$ x ← with k = $\frac{1}{2}$

y = $\frac{22}{2}$ x = 11x ← with k = 11

Thus A is the required equation

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

Step-by-step explanation:

18-2.5+7 there s your helllppppppppppp

Part A: The original triangle has a base of 18 feet and a height of 7 feet. To create the 2:5 scaled version of the deck, we can simply multiply the base and height of the original triangle by the scale factor of 2/5.

New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet

Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.

Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:

Area = (1/2) x base x height

Area = (1/2) x 18 x 7 = 63 square feet

To find the area of the new deck, we can use the same formula and plug in the new dimensions:

Area = (1/2) x 7.2 x 2.8 = 11.88 square feet

Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.

Part C: The ratio of the areas is:

63/11.88 = 5.303

The scale factor is:

2/5 = 0.4

To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:

5.303/0.4 = 13.2575

Therefore, the ratio of the areas is 13.2575 times the scale factor.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

The conclusion that can be made on the ages of the participants is 1. The median age of participants in group 2 is older than the median age of participants for group 1.

What is median ?

A median is the number in the center of a data collection that is written from least to greatest. When two numbers are in the center, the median is the mean of these two values.

On the line plot, we see that the Median Age for Group 1 is 15 years while the Median Age in Group 2 is 17 years. This therefore means that the median age of Group 2 is larger than Group 1.

A pack of cinnamon-scented pencils sells for $5.00. What is the sales tax rate if the total cost of the pencils is $5.35?

Answers

Answer: $0.35

Step-by-step explanation:

Answer: 7%

Step-by-step explanation:

Ok, we'll start by listing the facts.

Facts

Pack of pencils is $5

Total cost: 5.35

This means the sales tax is 35 cents, but we need to find the percentage to get the sales tax rate.

We can do this by dividing .35 by 5

0.35÷5= 0.07

Convert 0.07 to a percentage by multiplying it by 100

0.07x100= 7

Hence the sales tax rate is 7%. We can check to make sure this is correct by finding 7% of 5, and then adding the result to the 5.

7% of 5= 0.35

5+0.35= 5.35

Hope this helps, and brainliest would be appreciated :))

how do i do this can someone explain

Answers

Answer:3.5 cm

Step-by-step explanation: (6x-1)=(4x+6) add one on both sides 6x=4x+7 then subtract 4x on both sides 2x=7 divide both sides by 2 and get x=3.5

In a square, all sides are equal to each other. So, therefore, you can set both equations given equal to each other. Doing that you will get

6x-1=4x+6

From here you can begin to solve the equation (Move the whole numbers to one side and the x’s to the other).

When you do that you get

2x=7

Solve for x and you get

X=7/2 or 3.5

Now that you have the value of x you can plug it into the equation and solve for the length of the side

6x-1
6(3.5)-1=20cm

For both equations you should get the same result

4x+6
4(3.5)+6=20 cm

So the length is equal to 20cm

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

Answers

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.

2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.

3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.

4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).

5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.

6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.

7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.

By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

$\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}$

♥️ $\large{\underline{\textcolor{red}{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}$

To create a box plot for this data set, we need to find the minimum value, maximum value, median, and quartiles.

Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38

The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.

In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.

An account is opened with an initial balance of $950 and a simple annual interest rate of 1.6%. What is the balance after 5 years

Answers

the answer is $1,026.

Solving: Use Simple interest formula, I=Prt.

Make the rate into a decimal (1.6% -> 0.016)

plug in the numbers into the formula. 950 x 0.016 x 5 = 76$.

76$ will be our interest, now to find the balance we would have to add the the starting money (950) with our interest (76$), resulting in our answer of $1,026 after 5 years.

$1,026. This is because $950 multiplied by 1.6% is equal to $15.20. This multiplied by 5 years is equal to $76. $950 multiplied by $76 is equal to $1,026.
