i need help with this math thing cause i kinda sorta fell asleep in this class

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

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

Step-by-step explanation:

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

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:

Step-by-step explanation:

Assuming you're looking to find the missing angle measure, remember that in inscribed angles, such as angle DEF, the measure of the angle is half the measure of its intercepted arc. That means that the missing angle is half the measure of 228, which is 114, C.

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:

$230.65

Step-by-step explanation:

$179 marked down by 35 % = $116.35

computer mount= $99

cell holder= $56

marked down by 15% = $230.65 (230.6475)

Answer:

Step-by-step explanation

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:

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:

24

Step-by-step explanation:

A= ( 1 - r/100 ) P

135= (1 - 15/100 ) P

135= 0.85P

135/0.85= P

159= P

159- 135 = 24

Answer:

Mirror

Step-by-step explanation:

Answer:

x = -3

y = 2

Step-by-step explanation:

Let the two integers be x and y

sum is -1

x + y = -1 •••(i)

x-y = -5 •••••(ii)

From ii, x = -5 + y

substitute into i

-5 + y+ y = -1

-5 + 2y = -1

2y = -1 + 5

2y = 4

y = 4/2

y = 2

Recall;

x = -5 + y

x = -5 + 2

x = -3

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:

1/8 and 2/1 or 1:8 and 2:1

Step-by-step explanation:

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
