The direct variation equation to represent the relationship between the number of tickets and the cost of the ticket is y = 8x.

A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Given:

56, 48, 40, 32, 24, 16, 8, 0, y

7, 6, 5, 4, 3, 2, 1, 0, x

Here, x is the number of tickets and y is the cost of the ticket

As you can see that the cost of each ticket is $8,

Answer:

180 degrees in a triangle

Answer:

final amount = $16512.36

Step-by-step explanation:

The question asks us to find the value of Gavin's deposit of $12,000 after 16 years, given that the interest rate of 2% is compounded quarterly.

To do this, we have to use the following formula for compound interest:

[tex]\boxed{A = P(1 + \frac{r}{n})^{nt}}[/tex],

where:

A → amount at the end

P → principal (original) amount

r → interest rate (in decimal)

n → number of times per year that the interest is compounded

t → time (in years).

From the question, we know that the initial amount deposited is $12,000. Therefore, P = 12000. We also know that the interest rate is 2%, but the formula requires the rate to be in decimal, so r = 0.02. The time for which the money is deposited is 16 years, and therefore, t = 16. We are told that the interest is compounded quarterly, that is, every 3 months. This means that the interest is compounded 4 times yearly, so n = 4.

From the above information and formula, we can calculate the final amount:

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

⇒ [tex]A = 12000(1 + \frac{0.02}{4})^{4 \times 16}[/tex]

⇒ A = $16512.36

Therefore, the final amount after 16 years is $16512.36.

There is 46% probability of experiencing neither of the side effects.

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Given that,

While taking drug, chances of experiencing nausea (n)= 24 %,

Chances of experiencing decreased sexual drive (d) = 46 %.

Also, there are 60% chances of experiencing both side effects.

Use vain diagram to solve this type of questions,

Total chances of experiencing side effects = 8 + 30 + 16 = 54

The chances of experiencing neither of the side effects = 100 - 54 = 46

So there is 46% probability of experiencing neither of the side effects.

The number of bottles of soda is  4 and the number of bottles of juice purchased is  8.

We know that linear system of equation in two variables is required to solve the problem. Let suppose number of bottles of soda purchased by Jacob is x and number of bottles of juice purchased by Jacob is y

Since, it is given that Jacob bought 25 bottles in total, it means

=>x + y=12-----(eq1)

Also, it is given that total amount of sugar is 240grams.Now,amount of sugar present in soda bottle is 25x and amount of sugar present in juice bottles is 12y

Therefore,25x + 12y=240-----(eq2)

On solving eq1 and eq2,we get

=>x+y=12

and 25x+10y=240

Using elimination technique to solve, make x terms coefficient equal.

Multiplying eq1 by 25,we get

=>25x + 25y=25×12

=>25x +25y=300------(eq3)

Using eq3 and eq4,we get

=>25x+25y=300

and 25x+10y=240

Cancelling x terms, we get

=>15y=60

=>y=(60/15) grams

=>y=4 bottles

Now, putting value of y in eq1 ,we get

=>4+y=12

=>y=12-4

=>y=8bottles.

Hence, required value of number of bottles of soda is 4 and number of bottles of juice is 8.

Given that there were 9 people in a group. Some of them ordered chicken wings and rest people ordered the chicken wrap.

The cost of chicken wings is $14.99.

The cost of chicken wrap is $8.49.

The total bill was $115.41.

Assume that, x number of people ordered chicken wings.

Then (9 - x) number of people ordered chicken wrap.

The cost of 1 chicken wings is $14.99

The cost of x chicken wings is $14.99x.

The cost of 1 chicken wrap is $8.49.

The cost of (9 - x) chicken wrap is $8.49(9 - x).

The total cost of x chicken wings and (9 - x) chicken wrap is $[14.99x + 8.49(9 - x)]

= $[14.99x + 76.41 - 8.49x]

= $[6.50x + 76.41]      [ Subtract like terms]

According to the question,

6.50x + 76.41 = 115.41

Subtract 76.41 from both sides:

6.50x = 39

x = 6

Putting x = 6 in the expression (9 - x)
