PLEASE HELP! Marta Is Buying Soft Drinks For The Class Party. The Table Below Shows The Prices Of 4 Different

Answers

Answer 1

The price of a 10-ounce bottle is $0.79

The price of a 12-ounce bottle is $0.99

The price of a 20-ounce bottle is $1.64

The price of the 64-ounce bottle is $4.98

Package price of 10-ounce bottles = $3.19

Number of bottles in the package = 4

Price per bottle = Package price/Number of bottles = 3.19/4

= $0.79

Package price of 12-ounce bottles = $5.99

Number of bottles in the package = 6

Price per bottle = Package price/Number of bottles = 5.99/6

= $0.99

Package price of 20-ounce bottles = $6.56

Number of bottles in the package = 4

Price per bottle = Package price/Number of bottles = 6.56/4

= $1.64

Package price of 64-ounce bottles = $4.98

Number of bottles in the package = 1

Price per bottle = Package price/Number of bottles = 4.98/1

= $4.98

Answers

The correct responses for the arithmetic and exponential sequence and function are;

1. First part; 32 pennies

Second part; Approximately 50 days

2. 24.6 gallons

3,738.5 minutes

3. $67.2

Approximately 24 months

4. 1106.14 gallons

66.56 minutes

The difference is 1 is an arithmetic sequence while 3 is an exponential function

What is a an arithmetic sequence?

An arithmetic sequence is a group of numbers in which the difference between subsequent terms is a constant

1. The given parameters are;

The initial amount Savannah placed in the piggy bank = 5 pennies

The amount given to Savannah each day = 3 pennies

Required;

First part;

The amount Savannah will have after 10 days

Solution;

The mathematical model for the situation is an arithmetic sequence or progression

The equation for an arithmetic progression is;

[tex]a_n = a_1 + (n - 1) \times d[/tex]

Where;

[tex]a_n[/tex] = The amount after n days

[tex]a_1 [/tex] = The first amount Savannah placed in the piggy bank = 5 pennies

n = The number of days

d = The common difference between the amount present in consecutive days = 3 pennies

The amount after 10 days is therefore;

[tex]a_{10} = 5 + (10 - 1) \times 3=32[/tex]

The money after 10 days is 32 pennies

Second part;

The number of days it would take for there to be $1.50 in the piggy bank.

Solution;

100 pennies = $1.00

Therefore;

$1.50 = 150 pennies

Which gives;

150 = 5 + (n - 1) × 3

(n - 1) × 3 = 150 - 5 = 145

(n - 1) × 3 = 145

n - 1 = 145 ÷ 3

n = 145 ÷ 3 + 1 ≈ 49.3 ≈ 50

It will take approximately 50 days for the amount in the piggy bank to be $1.50

2. The volume of the pool = 1,500 gallons

The initial amount of water in the pool = 5 gallons

The rate at which water enters the pool = 2 gallons in 5 minutes

Required;

First part

The volume of water in the pool after 50 minutes

Solution;

2 gallons in 5 minutes = (2/5) gallons/minute = 0.4 gallons/minute

Therefore;

[tex]a_{50} = 5 + (50 - 1) \times 0.4 =24.6[/tex]

After 50 minutes, 24.6 gallons will be in the pool

Second part;

The time it will take to fill the pool is given by the equation;

[tex]1500 = 5 + (n - 1) \times 0.4[/tex]

number

Which gives;

n = 3738.5

It will take 3,738.5 minutes to fill the pool

3. The formula for finding the amount in the account is the compound interest formula;

[tex]\displaystyle{A = P\cdot (1 + r)^n }[/tex]

Where;

A = The amount in the account after n months

P = The initial amount in the account = $50.0

r = The interest rate = 3.0%

n = The number of periods (months)

After 10 months, we have;

[tex]\displaystyle{A = 50 \times (1 + 0.03)^{10} \approx 67.2 }[/tex]

The amount in the account after 10 months is therefore, approximately $67.2

Second part;

Double the initial amount is 2×$50 = $100

Which gives;

[tex]100 = \displaystyle{50 \times (1 + 0.03)^{n} \approx 67.2 } [/tex]

Which gives;

n ≈ 23.45

Therefore it will take approximately 23.45 months or approximately 24 months for the amount to double

4. Using the exponential function formula, we have;

Number of 5 minutes in 50 minutes = 10

[tex] \displaystyle{1500 \times (1 - 0.03)^{10} \approx 1106.14} [/tex]

The water remaining after 50 minutes is approximately 1106.14 gallons

The time it takes for there to be less than 1,000 gallons in the pool is given as follows;

[tex] \displaystyle{ 1000= 1500 \times (1 - 0.03)^{n}} [/tex]

Which gives;

n = 13.3

Therefore;

The water in the pool will be less than 1000 gallons after 13.3, 5 minute periods or 13.3 × 5 minutes≈ 66.56 minutes

Assuming they work until their cost become the same, obviously.

The difference between the first charge of painter A and painter B = 376 - 280 = 96.

The hourly cost difference between painter B and painter A = 15 - 12 = 3.

So, painter A in the first hour has 96 more dollars than painter B, and as every hour pass, the difference goes down by 3 (as painter B gets 3 more dollars every hour)

Therefore, it would take 96 : 3 = 32 hours for the cost to be the same

Recheck : After 32 hours, painter A has 376 + 32 x 12 = 760 (dollars)
painter B has : 280 + 15 x 32 = 760 (dollars)

Possible value for the actual distance that toy cart rolled before stopping

= Calculated distance - error distance

The slope of the given line is m =25.

The two points of the given line is (3,75) and (4,100).

The slope of the given line can be found using the formula point-slope equation.

y₂-y₁ = m(x₂-x₁)

We need to find the slope, so let us rearrange the equation,

m =  y₂-y₁ / x₂-x₁

where (x,₁y₁) and (x₂,y₂) is (3,75) and (4,100) respectively

So let us substitute these values in the above equation, we get

m = 100 - 75 / 4 -3

m = 25/1

m = 25

Therefore, the slope of the line passing through the point (3,75) and (4,100) is 25

What transformations take f(x) to g(x)?

Here we have the two functions:

f(x) = 3x + 1

g(x) = -3x - 5

So we start at f(x), first we apply a reflection across the x-axis so we change the sign to get:

g(x) = -f(x) = -3x - 1

Now we can apply a translation of 4 units downwards so we get:

g(x) = -f(x) - 4 = -3x - 1 - 4 = -3x - 5

The fact that employer contributions are tax-free is one of the best features of retirement programs. Only when an employee takes money out of their retirement accounts do taxes need to be paid.

Richard and teo have a combine age of 19 Richard is 4 years older than twice teo age how old are Richard and teo

Answers

Let “r” represent Richard’s age and “t” represent Teo’s age.

r + t = 19

2t + 4 = r

(2t + 4) + t = 19

Let’s remove the parenthesis and combine like terms:

2t + 4 + t = 19

→ 3t + 4 = 19

Now we can subtract 4 from both sides:

3t + 4 = 19

→ 3t = 15

Finally, division of 3 on both sides will evaluate Teo’s age:

3t = 15

→ t = 5

We can plug in Teo’s age for t and solve for Richard’s age now:

(2t + 4) + t = 19

→ 2(5) + 4 + 5 = 19

10 + 4 + 5 = 19

Richard is 14 because 19 - 5 = 14.

Graph the inequality on the axes below. y≥3/2x-1

Answers

The graph will be a shaded region above and including the straight line y = (3/2)x-1.

We are asked to graph the inequality y ≥ (3/2)x-1. Describing the graph of an inequality, it will be a region on one side of a straight line.

So first we need to sketch the straight line, y = (3/2)x-1.

So find two points (x, y) satisfying this equation of line because a line need at least two points.

x       y  

0       -1

2/3     0

So first sketch a line joining the points (0, -1) and (2/3,0). This line will lie below the origin. That is, origin lies on the region above this line.

So the line y = (3/2)x-1 divided the plane into two regions, one of which represents the inequality y ≥ (3/2)x-1. So to find this required region we will check if origin lies in the region for inequality.

Substituting (0, 0) into y ≥ (3/2)x-1,

0 ≥ -1, which is true.

Thus in the graph, the region for inequality is the region where the origin lies. Hence shade the region above the line y = (3/2)x-1. This is the graph of the inequality y ≥ (3/2)x-1.

A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix).

Answers

The number of fiction and non fiction books are 10 and 2 respectively.

How to find the number of fiction and non fiction books?

There are 5 times as many fiction books in the class library as there are nonfiction books.

Therefore,

let

x = number of non fiction book.

number of fiction book = 5x

The number of information books is 7 more than the sum of the number of fiction and nonfiction books.

Therefore,

number of information book = 7 + x + 5x

number of information book = 7 + 6x

There are 19 information books in the library.

Hence,

19 = 7 + 6x

19 - 7 = 6x

6x = 12

x = 12 / 6

x = 2
