The answer is 50.2^2. You find the area of the outer circle and the middle circle. Then subtract the area of the smaller one from the larger one.

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).

Answer:

∠C ≈ 11.978°

Step-by-step explanation:

sin (∠C)/5 = sin (95°)/24

=> sin (∠C) = 5 × sin (95°) ÷ 24

=> ∠C = [tex]sin^{-1}[/tex](5 × sin (95°) ÷ 24)

=> ∠C ≈ 11.978°

Answer:

A(t) = 50(0.97)^t

Step-by-step explanation:

3% = 0.03

1 - .03 = 0.97

A(t) = 50(1 - 0.03)^t

A(t) = 50(0.97)^t

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.

#SPJ2

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

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]

$230.65

Step-by-step explanation:

$179 marked down by 35 % = $116.35

computer mount= $99

cell holder= $56

total= $271.35

marked down by 15% = $230.65 (230.6475)

Answer:

Yes

Step-by-step explanation:

-1 < 6 + 2  True

-1 > 3 - 2(6)  

-1 > 3 - 12

-1 > -9   True

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:

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
