y= -4/3, or y= -1 1/3 depending on what answer type you need

Answer:

The value of y is $-1.33...$

Step-by-step explanation:

WKT, the given equation is $\frac{-1}{2} =\frac{3}{8} y$

Here, y is a variable.

Now, to solve the equation,

we need to multiply $\frac{8}{3}$ on both sides of the given equation, in order to get the values of y.

That is, $\frac{-1}{2}$ × $\frac{8}{3} =\frac{8}{3}$ × $\frac{3}{8} y$

⇒$-\frac{1}{2}$ × $\frac{8}{3}= y$

⇒$-\frac{8}{6}=y$

⇒$y=-\frac{4}{3}$

or $y=-1.333$

Therefore, the value of y is $-1.33...$.

A. 1607.7

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

$\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}$

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

$\hrulefill$

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

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.

Decide which measurement is greater. Place the correct symbol ( <, >, =) on the line between the measurements.
5 gallons _______ 18 quarts

1 pint 4 cups _____ 32 fl oz

3 pints ______ 8 cups

13 quarts _______ 4 gallons

4 quarts _______ 9 pints

Answers

The measurements that are greater using the correct symbol <, >, =) are:

5 gallons > 18 quarts1 pint 4 cups > 32 fl oz3 pints < 8 cups13 quarts < 4 gallons4 quarts < 9 pints

How to determine the greater measurement?

Gallons and quarts

1 gallon = 4 quarts.

So, we have:

5 gallons = 20 quarts i.e. 5 * 4

Hence,

5 gallons > 18 quarts

Pints and cups to fl oz

1 cup = 0.5 pints.

So, we have:

1 pint 4 cups = 1 pint + 2 pints

1 pint 4 cups = 3 pints

1 pint = 16 fl oz.

So, we have:

1 pint 4 cups = 16 * 3 fl oz

1 pint 4 cups = 48 fl oz

Hence,

1 pint 4 cups > 32 fl oz

Pints and cup

1 cup = 0.5 pints.

So, we have:

8 cups = 4 pints

Hence,

3 pints < 8 cups

Quarts and gallon

1 gallon = 4 quarts.

So, we have:

4 gallons = 16 quarts

Hence,

13 quarts < 4 gallons

Quarts and pints

1 quart = 2 pints.

So, we have:

4 quarts = 8 pints

Hence,

4 quarts < 9 pints

Step-by-step explanation:

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Answers

Answer:

∠1 and ∠2 are supplementary angles.

∠6 and ∠8 are vertical angles

∠1 and ∠5 are corresponding angles.

Step-by-step explanation:

∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.

∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.

<1 and <2 are Supplementary angles

<1 and <5 are Corresponding angles

<6 and <8 are Vertical angles

Given that d II e

when a transversal intersects two parallel lines the following conditions are true:

Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.

Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.

Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles

A cardboard storage carton has a length of 3 feet, a width of 2 feet, and a volume of 12 ft³.whatis the minimum amount of cardboard needed to make the box? [hint: you're given volume, so find the missing height. then use your 3 dimensions to find the total surface area.]

Answers

The minimum is :32: ft.

Brainlist pls

To find the missing height, we can use the formula for the volume of a rectangular box:

Volume = Length x Width x Height

Substituting the given values, we get:

12 = 3 x 2 x Height

Solving for the height, we get:

Height = 12 ÷ (3 x 2) = 2 feet

Now, we can use the dimensions to find the total surface area of the box. The surface area of a rectangular box can be found using the formula:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the box, respectively.

Substituting the given values, we get:

Surface Area = 2(3 x 2) + 2(3 x 2) + 2(2 x 2) = 12 + 12 + 8 = 32 square feet

Therefore, the minimum amount of cardboard needed to make the box is 32 square feet

Jonathan needed to get his computer fixed. He took it to the repair store. The technician at the store worked on the computer for 3 hours and charged him $141 for parts. The total was $336. Write and solve an equation which can be used to determine x, the cost of the labor per hour.

Answers

Answer: x = 65

================================================

Work Shown:

x = cost of labor per hour

3x = cost of the 3 hours of labor

3x+141 = cost of labor plus parts = total cost

3x+141 = 336

3x = 336-141

3x = 195

x = 195/3

x = 65

The hourly wage is $65 per hour for labor.

------------

Check:

1 hour = 65 dollars in labor costs

3 hours = 3*65 = 195 dollars in labor costs

195+141 = 336 dollars total

The answer is confirmed.

195 is the answer
