Suppose c was a total membership cost for m the two equations that model c are c=30m+50 an c=20m+100

Answer:

[tex]B' = (-2,-3)[/tex]

Step-by-step explanation:

Given

[tex]A = (1,-4)[/tex]

[tex]B = (4,-6)[/tex]

[tex]C = (2,-1)[/tex]

reflection across y

[tex]d = \frac{1}{2}[/tex]

Required

New coordinate of B

When reflected across the y-axis.

The rule is:

[tex](x,y) \to (-x,y)[/tex]

So:

[tex](4,-6) \to (-4,-6)[/tex]

Next is a dilation by 1/2

To do this, we multiply the new point by 1/2

So:

[tex]B' = (-4,-6) * \frac{1}{2}[/tex]

[tex]B' = (-4* \frac{1}{2},-6* \frac{1}{2})[/tex]

[tex]B' = (-2,-3)[/tex]

Answer:

0.966

Step-by-step explanation:

483:500 = 0.966

i hope this is right x

The required ratio would be 0.966 which is expressed in decimal form.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Josh wrote 483 out of an expected 500 words from his essay which is given in the question.

According to the given information, the ratio would be written as:

⇒ 483 : 500

⇒ 483 / 500

Apply the division operation, and we get

⇒ 0.966

Therefore, the required ratio would be 0.966 which is expressed in decimal form.

Answer:

[tex]Pr = \frac{9}{49}[/tex]

Step-by-step explanation:

Given

[tex]d = 28[/tex] --- big circle

[tex]A_2 = 36 \pi[/tex] --- area of small circle

Required

Probability that a point selected lands on the small circle

Calculate the area of the big circle using;

[tex]A_1 = \pi r^2[/tex]

Where

[tex]r = d/2[/tex]

So, we have:

[tex]r = 28/2 = 14[/tex]

This gives:

[tex]A_1 = \pi * 14^2[/tex]

[tex]A_1 = \pi * 196[/tex]

[tex]A_1 = 196\pi[/tex]

The probability that a point selected lands on the small circle is calculated by dividing the area of the small cicle by the big circle

This gives:

[tex]Pr = \frac{36\pi}{196\pi}[/tex]

[tex]Pr = \frac{36}{196}[/tex]

Simplify

[tex]Pr = \frac{9}{49}[/tex]

Step-by-step explanation:

Answer:

15%

Step-by-step explanation:

You kind of have two ways to do this:

Way 1:

Find how many 60 cents fit into $4. To do that, divide $4 by $0.60 or 400 by 60. You get 6.66666667.

You can divide 100 by 6.66666667, and get 15%,

Way 2:

Knowing that 400 cents is 100%, you can divide 60 by the same number that you divide 400 by to get to 100. To get from 400 to 100, you divide by 4, so divide 60 by 4 and get the same answer, 15%

Hope that helps :)

Answer:

25 - 4x^8

Step-by-step explanation:

Use FOIL here.

Combine the first terms of both expressions.

5 * 5 = 25

Combine the outer terms of both expressions.

2x^4 * 5 = 10x^4

Combine the inner terms of both expressions.

-2x^4 * 5 = -10x^4

Combine the last terms of both expressions.

-2x^4 * 2x^4 = -4x^8

(a^x * a^y = a^(x+y).)

Now add those terms.

25 + 10x^4 - 10x^4 - 4x^8

Combine like terms to get:

25 - 4x^8.

Answer:

[tex]25 - 4x^8[/tex]

Step-by-step explanation:

1)  [tex](5 - 2x^4) (5 + 2x^4)[/tex]

Simplify using [tex](a - b)(a + b) = a^{2} - b^{2}[/tex]

2)  [tex]5^{2} - (2x^4)^{2}[/tex]

Evaluate the power

3)  [tex]25 - (2x^4)^{2}[/tex]

4)  [tex]25 - 4x^8[/tex]

Answer:

e) 20

Step-by-step explanation:

Segment lengths:

|(2, 7) -> (8, 7)| = |(8-2, 7-7)| = |(6, 0)| = 6

|(8, 7) -? (8, 11)| = |(8-8, 11-7)| = |(0, 4)| = 4

because we know it's a rectangle, we can infer that the other two sides also have lengths 4 and 6, so the perimeter is 4+4+6+6=20

Hello! answer: 105

Step-by-step explanation:

When doing these for squares you have to do base × height and for triangles you do base × height ÷ 2 So Lets do the triangles sense there more complex so we can get them out of the way. The base for the triangles our 5 and the height is 8 so we will do 5 × 8 = 40 now we will just divide that by 2 so 40 ÷ 2 = 20 now sense we have four identical triangles we will just multiply 20 by 4 so 20 × 4 = 80 now for the 1 in the middle its nice and simple just 5 × 5 so 5 × 5 = 25 now we just add 80 + 25 and 80 + 25 = 105 So 105 is the area! Hope that helps!

Answer:

D.

Step-by-step explanation:

Based on the attached picture we can say that function representing these values would be exponential because the Y values for successive Integer values of X have a common ratio of 16. This can be proven by multiplying each one of the y values by 16, which would give us the next y value in the successive set. For example,

2.5 * 16 = 40

40 * 16 = 640

640 * 16 = 10,240

Meaning that the values have a common ratio of 16, and are increasing exponentially.

Answer:

each lb of jellybeans = $1.50

each lb of almonds = $2.75

Step-by-step explanation:

let j = jellybean cost for each pound

let a = almond cost for each pound

3j + 2a = 10

5j + 6a = 24

Using elimination method:

15j + 10a =50

15j + 18a = 72

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

-8a = -22

a = 2.75

using 3j + 2a = 10

3j + 2(2.75) = 10

3j + 5.5 = 10

3j = 4.5

j = 1.5

Answer:

Step 1:

Subtract $19 from total

366.50 - 19 = 347.5

Step 2:

Divide this total by the ticket price

347.50 / 34.75 = 10

Step 3:

You have your answer

10 people can go to the amusement park

Answer:

as many as 11 people

Step-by-step explanation:

n = # of people

5.50 + 34.75n ≤ 387.75

subtract 5.5 from each side to get:

34.75n ≤ 382.25

divide each side by 34.75

n ≤ 11

Answer:

Ana  spent $17  per book on average.

Juan  spent $14.78  per book on average.

y = $15 + 17x--------- equation 1

y= $10 + 14.78 x------------- equation 2

Step-by-step explanation:

Ana has to pay a yearly fee of $15 to join.

She spends a total of $525 for 30 books.

The amount spent on books = Total amount - yearly fee

                                                 = $525- $15= $510

Price per book on the average = $510/30= $ 17

Ana  spent $17  per book on average.

Juan has to pay a yearly fee of $10 to join.

He spends a total of $350 for 23 books.

The amount spent on books = Total amount - yearly fee

                                                 = $350- $10= $340

Price per book on the average = $340/23= $ 14.78≅ $15

Juan  spent $14.78  per book on average.

The function can be established if y gives the total cost and x gives the number of books

y = $15 + 17x--------- equation 1

y= $10 + 14.78 x------------- equation 2

Juan has a better deal because the yearly fee is less also the price per book is less.

Answer:

(3, -3)

Step-by-step explanation:

To solve for a system of equations, use substitution.

First, solve for one variable in an equation.

2x - 3y = 15

Add 3y to both sides.

2x = 3y + 15

Divide both sides by 2 to get x by itself.

x = 1.5y + 7.5

Put this in the other equation.

5x + 2y = 9

Substitute the variable.

5(1.5y + 7.5) + 2y = 9

Distribute the 5 inside the 1.5y + 7.5.

7.5y + 37.5 + 2y = 9

Combine like terms.

9.5y + 37.5 = 9

Subtract 37.5 from both sides.

9.5y = -28.5

Divide both sides by 9.5.

y = -3.

Now take this value and put it in the other equation to get your x.

2x - 3y = 15

Substitute variable.

2x - 3(-3) = 15

Multiply.

2x + 9 = 15

Subtract 9 from both sides.

2x = 6

Divide both sides by 2.

x = 3.

Your pair is (3, -3).

The series using sigma notation is [tex]^5\sum_{n=1}=4(4)^{n-1}[/tex]. Therefore, option A is the correct answer.

The general formula for finding the sum of an infinite geometric series is S=a/r-1, where s is the sum, a1 is the first term of the series, and r is the common ratio.

Given that, sum = 4 + 16 + 64 + 256 + 1024

Using sigma notation, this can be expressed as:

[tex]^5\sum_{n=1}=4(4)^{n-1}[/tex]

Therefore, option A is the correct answer.
