Help!!!! I don't know how to do this stuff..

Step-by-step explanation:

Permutation is "How many ways can you arrange 'r' from a set of 'n' if the order matters?"

For #7, it would be "how many ways can you pick 2 things out of 6 things when the order matters?"

The steps for this is in the picture.

For #9, you would do the same as #7 and just add -4 to your final answer

Answer:

125 students ride their bike to school

Step-by-step explanation:

We can set a proportion.

5 / 32 = x / 800

where x is the number of students out of 100 who ride their bikes.

Cross multiply.

32x = 4000

Divide both sides of the equation by 32.

x = 125

125 students out of 800 students ride their bikes to school.

Out of the 40 prizes, 15 prizes were for Kazoos and 35 prizes were for whistle

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the diagram, the ratio is represented, hence:

Number of Kazoos = (3/8) * 40 = 15

Number of whistles = (5/8) * 40 = 35

Out of the 40 prizes, 15 prizes were for Kazoos and 35 prizes were for whistle

Answer:

90 apples

Step-by-step explanation:

1st class did 1/3, 1/3 of 60 is 20, 60-20 is 40, 40 into 2.25 or 2 1/4 = 90 because 40 x 2 = 80 and 1/4 of 40 is 10, 10+80 = 90, so the second class needs 90 apples

Answer:

90 apples

Step-by-step explanation:

First, we need to find 1/3 of the total number of pies, which is the number of pies the first class made. To do this, we divide 60 by 3 (or multiply 60 by 1/3):

60 ÷ 3 = 20

This means the first class made 20 pies and that the second class has to make 40 pies (60 - 20 = 40)

1 pie needs 2 1/4 apples

To find how many apples the second class will need, we must multiply 40 (the number of pies) • 2 1/4 (the number of apples needed for 1 pie)

40 • 2 1/4 = 90

This means 90 apples are needed for the second class to make the remaining pies

Answer:

let the vertices on either side of the 0 be A and B

then let the vertex opposite of O be C

First, angle ACB will be equal to 90° as it is the angle that lies on the same arc as the diameter. From there you can find angle y with angle A+ angle B+ Angle C=180°

then you can find the angle complementary to x with the same formula then you can subtract that angle with 90° to get x.Step-by-step explanation:

answer I need a picture please

The graph given below is the rational function y = 1/(x + 1).

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

In the case of the function y = 1/(x + 1), the numerator is a constant function, which means that the function has a horizontal asymptote at y = 0.

The denominator, x + 1, is a linear function, which means that the function has a vertical asymptote at x = -1.

Therefore, the graph of the function will have a shape that is similar to a hyperbola.

Thus,

The graph given below is the rational function y = 1/(x + 1).

Can't solve this sorry. :(

The integral distributes over the sum:

[tex]\displaystyle \int \left(4x^{\frac34} + 2x^{\frac34} + 4x^{\frac12} + 2x + 2\right) \, dx \\\\\\ = \int 4x^{\frac34} \, dx + \int 2x^{\frac34} \, dx + \int 4x^{\frac12} \, dx + \int 2x \, dx + \int 2 \, dx[/tex]

Then just integrate each term using the power rule; if n ≠ -1, then

[tex]\displaystyle \int x^n \, dx = \frac{x^{n+1}}{n+1} + C[/tex]

Then your integral is simply

[tex]\displaystyle \int \left(4x^{\frac34} + 2x^{\frac34} + 4x^{\frac12} + 2x + 2\right) \, dx \\\\\\ = \frac{4x^{\frac34+1}}{\frac34+1} + \frac{2x^{\frac34+1}}{\frac34+1} + \frac{4x^{\frac12+1}}{\frac12+1} + \frac{2x^2}2 + \frac{2x^1}1 + C \\\\\\ = \frac{16}7 x^{\frac74} + \frac87 x^{\frac74} + \frac83 x^{\frac32} + x^2 + 2x + C \\\\\\ = \boxed{\frac{24}7 x^{\frac74} + \frac83 x^{\frac32} + x^2 + 2x + C}[/tex]

Change 288 square inches to feet

(Keep in mind that 1 feet equals 12 inches)

[tex]\huge\rm{SOLUTION:}[/tex]

Follow these steps to convert to square feet.

Step 1: Convert an inch to a square inch.

If 1 feet equals 12 inches, then

1 square feet equals (12) inches equals 144 square inches

As a result, 144 square inches equals one square feet.

Step 2: Using the unitary method, we obtain

288 square inches = 288/144 square feet.

288 square inches = 2 square feet

As a result, 288 square inches equals 2 square feet.

Answer:

3:2

Step-by-step explanation:

Answer:

Part 1) The ratio of buttons in package A to package B is 7:12

Part 2) For every 1 button in package C, there are 5 in package D.

Part 3) The ratio of buttons in package A to the total number of buttons is 1:5

Step-by-step explanation:

Part 1.

To find the ratio of buttons in package A to package B, we first have to identify how many buttons are in each package.

Package A: 35

Package B: 60

One way we can find the ratio of 35 to 60 is to find a common factor between the two numbers.

Well, both 35 and 60 have a common factor of 5.

Now we divide both numbers by 5 to simplify

35 / 5 = 7

60 / 5 = 12

Now we have the ratio of 7:12

It cannot be simplified anymore since 7 and 12 have no common factors

Part 2.

To find the answer to this, we have to find the ratio of buttons in package C to package D.

Package C: 10 buttons

Package D: 50 buttons

Now we find a common factor between the two numbers

The greatest factor is 10

Now we divide both numbers by 10 to simplify

10 / 10 = 1

50 / 10 = 5

So, our ratio is 1:5

That means for every 1 button in package C, there are 5 in package D.

Part 3.

To find this ratio, we have to identify the number of buttons for both sides.

Package A: 35

All Packages: 60 + 10 + 50 + 20 + 35 = 175

So, let's find the greatest common factor between 175 and 35

Well, the greatest common factor is 35, since 35 is a factor of 175

35 / 35 = 1

175 / 35 = 5

The ratio of buttons in package A to the total number of buttons is 1:5

Hey there!

(3 * 2)^2

= (3 + 3)^2

= 6^2

= 6 * 6

= 6 + 6 + 6 + 6 + 6 + 6

= 12 + 12 + 12

= 24 + 12

= 36

Therefore, your answer is: 36
