Answer:

Length: 6

Width: 5

Step-by-step explanation:

Givens:

Let L=length and w=width

Area= 30 = Lw

Perimeter = 22 = L + L + w + w= 2L + 2w

L= w+1

Plug in the values into the equation for the perimeter

22= 2L+ 2w

22= 2(w+1)+ 2w

22=2w+2+2w

22=4w+2

20=4w

5=w

Plug w into the equation for L

L=w+1

L=6

We don't have to use the formula for area in this question.

Honestly I think the easiest way to thing of this problem is by looking at a multiplication table. This method won’t work for more complex problems, but for this one I think it will be the easiest method to understand. If you want a more in detail explanation just reply to this and Ill explain how to solve it using equations.
Basically, for any method you need to know the equation for Area and for Perimeter (I will be using • to represent multiplication):
Area(A) = L•W
Perimeter(P) = L + L + W + W
You can also think of perimeter as
P = 2L + 2W
Since we know that the length of the rectangle needs to be 1 unit longer than the width, you basically need to find 2 numbers with a difference of 1 that multiply together to get 30 and that can be multiplied by 2 and added together to get 22. If you look at a multiplication chart you will see that 6 and 5 are 1 unit apart and multiply to get 30. Also, 6•2=12 and 5•2=10. If you add 12 + 10 you get 22. Therefore, your solution would be:

L = 6
W = 5

Like I said I’m happy to assist you further if you want to know how to solve it using more complex equations, which will be necessary on more advanced problems. Just let me know if you want me to! Hope this helped good luck!

Daniel the salesman has 3,000 bottles of extra strong fertilizer to sell. Each of the bottles cost $40 each. He sells 105 to Chuck The Farmer,706 to Maria the Gardener, 300 to Nate the Tester,200 to Ivy the Girl Scout and 900 to Mario the Chef. How much money did he make? How many bottles did he sell? How many bottles does he have left over?

Answers

you add all sales numbers to get 2,211. then you multiply that by 40 because that’s the amount of each. which is 88,440, that’s how much money he made. then you subtract 2,211 and 3,000 to get 789 which is how many bottles are left over.

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.

AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!

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.

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Since the area is equal to length times width, and you know your area has to be 30, you can plug in your values like this:

(2x+7) x = 30

you can distribute to make this easier

2x^2 + 7x = 30

you can plug this into quadratic formula by setting the equation =0, so:

2x^2 +7x -30 = 0

where 2x^2 = a
7x = b
and -30 = c

you can plug this into your calculator and get an answer of

X = 2.5

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5 miles.

What is multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

Expression for the Total of Distance ran by Maria

Total distance = Distance ran each day × Number days

Given the data in the question;

Distance ran each day by Maria Dm = 3.7miles

Number days ran n = 15days

Total number of distance ran by Maria TDm = ?

Hence, Total distance = Distance ran each day × Number days

TDm = Dm × n

We substitute in our values

TDm = 3.7miles × 15

TDm = 55.5miles

Thus, the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5miles.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

Step-by-step explanation:

You want the area of the given composite shape.

Composition

The shape is already divided for you into a lower part that is a trapezoid and an upper part that is a parallelogram.

Trapezoid

The area of the trapezoid is given by ...

A = 1/2(b1 +b2)h

A = 1/2(14 +7)(6) = 63 . . . . square centimeters

Parallelogram

The area of the parallelogram is given by ...

A = bh

A = (10)(5) = 50 . . . . square centimeters

Figure area

The area of the figure is the sum of the areas of its parts:

figure area = trapezoid area + parallelogram area

figure area = 63 cm² +50 cm² = 113 cm²

The area of the figure is 113 square centimeters.
