Based on the information, it can be inferred that the difference in the circumference of the two circles is 6.31 cm.

To calculate the circumference of a circle we must apply the following formula:

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).

According to the above, the difference of the circumferences would be 6.31 cm.

To calculate the area of the circle we must apply the following formula.

A =\(\pi r^{2}\)

r = radio del círculo.

How to calculate the circumference of a circle?

To calculate the circumference of a circle we must apply the following formula:

2R

R = Radius of the circle.

According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:

21 = 6.28

22 = 12.59

So, to find the difference between the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).

12.59 - 6.28 = 6.31

According to the above, the difference in the circumferences would be 6.31 cm.

How to calculate the area of the circle?

To calculate the area of the circle we must apply the following formula.

A =

r = radio del círculo.

According to the above, the radiO of both circles would be:

= 3.14

= 25.13

Additionally, to find the difference we must subtract these values:

25.13 - 3.14 = 21.99

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:

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:

Answer:

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles are 12. So, we then know that a = 20.

(Root 15^2-9^2=12) (Root 12^2+16^2=20)

Another way is using the whole triangle. The step above used two triangles. The two triangles together makes a big right triangle, so we can again use the Pythagorean theorem. So, the answer again is 20.

(Root 25^2-15^2=20)

Step-by-step explanation:

Using the Pythagorean theorem we can know from the first triangle that the height of the two triangles is 12. So, we then know that a = 20.

We have to find the value of ‘a’ using two different ways.

By the Pythagorean theorem,

By cross multiplication,

16(25) = a2

a2 = 400

Taking square root,

a = 20

Therefore, the length of the other side a = 20.

You can calculate the mean value by adding up the numbers and then dividing the result by the number of numbers. For instance, to find the mean value of 4, 1, 3, and 8, first, add up the numbers: 4+1+3+8=16 4 + 1 + 3 + 8 = 16.

Surface Area = 1.92m^2

Step-by-step explanation:

r1 & h1= big cylinder

r2 & h2= small cylinder

SA= 2π(r1xh1) + 2π(r2xh2) + [πr2^2 - πr1^2]

SA= 2π(25)(90) + 2π (15)(40) + [π(25)^2 - π(15)^2]

SA= 14137.17cm^2 + 3769.91cm^2 + [1963.50 - 706.86]

Answer:

70 degrees

Step-by-step explanation:

2x+3x-20+x+20=180

( angles in a triangle add up to 180 degrees)

as you want to find one x you need to move everything else to the other side: first collect all the like terms: 6x=180

in order to find x you need to divide 180 by 6 which is equal to 30

therefore x=30

if you substitute this into XYZ it would be: 3(30)-20

90-20=70

therefore XYZ=70 degrees

Hope this helped

Answer:

70

Step-by-step explanation:

So we know that the angles of a triangle equal up to 180 degrees. So let's make an equation. So we can do:

2x+(3x-20)+(x+20) = 180

Simplify:

6x=180

x=30

We can also plug this in to check our work. So it would be:

60+(90-20)+(30+20)

simplify

70+50+60=180

Then we have to find angle XYZ so we do 90-20=70

If 10 students are watching a 2 hour and 42 minute long movie.  6 students are watching the second movie.

We can use proportions to solve this problem. Let's start by finding the total number of minutes in the first movie:

M = 2 hours x 60 minutes/hour + 42 minutes = 120 minutes + 42 minutes = 162 minutes

Now, we can set up a proportion to find the number of students watching the second movie:

S/M = S'/M'

where S is the number of students watching the first movie (which we know is 10), M is the number of minutes in the first movie (162), S' is the number of students watching the second movie (which we want to find), and M' is the number of minutes in the second movie (91).

Substituting in the values we know and solving for S', we get:

10/162 = S'/91

S' = (10 x 91) / 162 = 5.62

Since we can't have a fractional part of a student, we need to round our answer to the nearest whole number. Therefore, approximately 6 students are watching the second movie.

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get
