The scatter plot shows the relationship betweeen the number of hours students spend watching television and the numer of hours they spend with family each week.

What is the y-intercept of the line of best fit and what does it represent?

11.5 hours; the number of hours students spend with family in a week when they do not watch television

9.2 hours; the number of hours students watch television in a week when they do not spend time with family

9.2 hours; the number of hours students spend with family in a week when they do not watch television

11.5 hours; the number of hours students watch television in a week when they do not spend time with family

### Answers

9.2 hours; the number of hours students watch television in a week when they do not spend time with family

Step-by-step explanation:

We are given,

The x-axis represents the time spent with family and the y-axis represents the time spent on watching television.

Now, y-intercept is the point where the scatter plot crosses y-axis.

From the scatter plot and and according to the options, the data point is located at x= 0 and y= 9.2.

That is, the y-intercept represents that students watched television for 9.2 hours when they do not spend time with their family.

### Answers

**Answer:**

8

**Step-by-step explanation:**

The sum of the internal angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5, hence

sum = 180° × 3 = 540°

Each exterior angle plus interior angle = 180°

Subtract each exterior angle from 180 for corresponding interior angle.

180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118

Sum the 4 interior angles and subtract from 540 for 5 th interior angle

5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°

The 5 th interior angle and 12x sum to 180 ( same reason as above )

Hence

12x + 84 = 180 ( subtract 84 from both sides )

12x = 96 ( divide both sides by 12 )

x = 8

What is the volume of a hemisphere with a radius of 40.7 in, rounded to the nearest tenth of a cubic inch?

### Answers

**Answer:**

[tex](\frac{4}{3} \pi 40.7^{3})/2[/tex]

[tex]\pi =3.14[/tex]

[tex](4*3.14*40.7^{3} )/3 = 282,261.5[/tex]

[tex](282,261.5)/2 = 141,130.7 in^{3}[/tex]

**Step-by-step explanation:**

**1. Volume of sphere**

[tex]V=\frac{4}{3} \pi r^{3}[/tex]

**2. Volume of hemisphere**

[tex]V=(\frac{4}{3} \pi r^{3} )/2[/tex]

The **volume **of hemisphere is 1,41,130.7 cubic inch.

What is hemisphere?

The words **hemisphere **and sphere can be separated into **hemi**, which denotes half, and **sphere**, which refers to the mathematical 3D shape. Consequently, a **hemisphere **is a 3D geometric object that is made up of half of a **sphere**, with one side being flat and the other being a **bowl**-like shape. It is created by **precisely **cutting a spherical along its diameter, leaving behind two identical **hemispheres.**

Given the **radius **of hemisphere = 40.7 inches

to find the volume,

**volume **of hemisphere = 2/3πr³

volume of hemisphere = 2/3(3.14)(40.7)³

**volume **of hemisphere = 2/3(3.14)(67419.143)

volume of **hemisphere **= 1,41,130.7 cubic inch.

Hence the **volume **is 1,41,130.7 cubic inch.

pls help i give brainliest and 5 stars

### Answers

**Step-by-step explanation:**

Explanation:

The formula for volume of a sphere is:

V=43πr3

Since we know the volume, and have to find the diameter (twice the radius), we need to determine the radius first.

Hence, using the given data:

2304π=43πr3

We can cancelπfrom each side.

2304=43r3

Multiply both sides by34.

2304×34=34×43r3

2304×34=34×43r3

2304×34=r3

5762304×34=r3

576×3=r3

To find the cube root, we separate the factors of the number on the left.

3⋅3⋅3⋅4⋅4⋅4=r3

(3⋅4)(3⋅4)(3⋅4)=r3

12×12×12=r3

12=r

Since the radius (r) is12, the diameter, which is2r, will be:

2×12=24

A piece of duct measures 48 inches. When pieces are fitted together, 1 72 inches is lost connecting each successive length of duct. On the job 7 and 12 pieces of ducting are used. What, in inches is the total length of the finished duct?

### Answers

**Answer:**

A piece of duct measures 48 inches.

In each connection, we lost 1.72 inches (it also could be 1/2 inches, but i will go with the other option)

Then:

If we have 7 pieces of duct connected we have 5 connections (the ones in the extremes are not connected between them)

So here we have 7 times 48 inches for the pieces, minus 5 times 1.72 inches for the connections, the length is:

L = 7*48in - 5*1.72in = 327.4 inches.

for the 12 pieces duct, we have 12 pieces and 10 connections, so the length is:

L = 12*48in - 10*1.72in = 558.8 in

Now, if we want to make only one duct with those two, then we must add their lengths, but if we connect them, we also need to subtract the 1.72in of the new connection:

L = 558.8 in + 327.4 in - 1.72in = 884.48 in

The math team wraps gifts as a way to raise money for traveling to competitions. They offer two choices: a plain wrapping or a decorative wrapping with bows.

The first column is labeled Plain Gifts Wrapped with entries 10, 25, 16. The second column is labeled Decorative Gifts Wrapped with entries 9, 12, 12. The third column is labeled Total Raised in dollars with entries 47, 86, 68. Which statement describes the amounts the team charged for wrapping gifts? The team charged $1 to wrap a gift with no bow and $2 to wrap a gift with a bow. The team charged $2 to wrap a gift with no bow and $3 to wrap a gift with a bow.

Gift-Wrapping Fundraiser

Plain Gifts Wrapped Decorative Gifts Wrapped Total Raised in dollars

10 9 47

25 12 86

16 12 68

Let's define:

x: $ charged per gift for Plain Gifts Wrapped

y: $ charged per gift for Decorative Gifts Wrapped

From 2nd 3rd row:

25x + 12y = 86

16x + 12y = 68

Subtracting them:

25x + 12y - (16x + 12y) = 86 - 68

9x = 18

x = 18/9 = 2

Replacing x = 2 into the first equation:

25(2) + 12y = 86

12y = 86 - 50

12y = 36

y = 36/12 = 3
