The amount of the down payment is:     $ 108.08

Step-by-step explanation:

It is given that:

You purchase a new LCD monitor for $1,351.

You put a 8% down payment and $59.56 per month on a 24 month purchase plan.

This means that the down payment made is 8% of the total amount of the LCD monitor.

i.e.

The amount of the down payment= 8% of 1,351

i.e.

The amount of the down payment= 0.08 of 1,351

i.e.

The amount of the down payment=0.08×1,351

Answer:

x = 8, y = 1

Step-by-step explanation:

11x - 20y = 28 ...(1)
3x + 4y = 36
or 15x + 20y = 180 ...(2)
Adding (1) and (2),
26x = 208
Or x = 8
Now, 3x + 4y = 36
3(8) + 4y = 36
4y = 36 - 32 = 4
so y = 1

The area of the oil spill after 2 hours is 300 square  meters

A rate of change describes the rate at which one quantity changes in relation to another quantity.

Since the oil spill spreads 25 square meters every 1/6 hour. We can write:

rate = 25/(1/6) = 150 square meters per hour

In 2 hours:

area = 2 * 150

area = 300 square meters

The equation of the circle that meets the specified requirements is x^2 + y^2 = 89, with the center at the origin and going through P(5, 8).

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

Here,

The equation of a circle with center at the origin (0,0) and passing through the point (x1,y1) can be found using the distance formula.

The distance between a point (x1, y1) and the origin (0,0) is given by:

sqrt((x1-0)^2 + (y1-0)^2) = sqrt(x1^2 + y1^2)

Let's call the radius of the circle r. We know that the distance between the point (x1,y1) and the origin is equal to r. So, we can set up the equation:

sqrt(x1^2 + y1^2) = r

Substituting the values x1 = 5 and y1 = -8, we have:

sqrt(5^2 + (-8)^2) = r

Solving for r, we get:

r = sqrt(5^2 + (-8)^2) = sqrt(25 + 64) = sqrt(89)

Finally, we can write the equation of the circle in standard form using the center (0,0) and radius r:

(x - 0)^2 + (y - 0)^2 = r^2

x^2 + y^2 = r^2

x^2 + y^2 = 89

The  equation of the circle that satisfies the stated conditions that is center at the origin, passing through P(5, −8) is x^2 + y^2 = 89.

Tiffany didn't deposit any more money and didn't withdraw any,

her balance is $1,413.82.

Compound interest is computed as interest on the principle of an account plus any accrued interest.

Compound interest can be calculated using the following formula:

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

,where x = compound interest

P = principal (the initial deposit or loan amount)

r = annual interest rate

n = the number of compounding periods per unit of time

t = the number of time units the money is invested or borrowed for

Given:

Tiffany makes some extra money selling vinyl's to teachers.

She deposited the $1,245 extra money into an account that earned 3.7% interest that was compounded annually.

First, convert R as a percent to r as a decimal

r = R/100

r = 3.7/100

r = 0.037 rate per year,

Then solve the equation for A

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

A = 1,245.00(1 + 0.037[tex])^{3.5}[/tex]

A = $1,413.82

Step-by-step explanation:

The equations obtained from evaluation of the data in the table and the predicted cost of hiring the DJs are as follows;

Part B

The equation representing the cost of hiring Celinda is; c = 36·h + 16

The equation representing the cost of hiring Brian is; c = 38·h + 4

Part C

The cost of hiring Celinda for 5 hours is $196

Cost of hiring Brian for 5 hours is $194

A linear equation is an equation that has an highest index of 1.

Part B

The first difference in the cost of hiring each DJ is presented as follows;

Celinda; 160 - 124 = 124 - 88 = 88 - 52 = 36

Brian; 156 - 118 = 118 - 80 = 80 - 42 = 38

The first difference are constant, therefore, the relationship are linear, which can be represented by linear equations.

The difference between the subsequent values in the number of hours of 1 indicates that we get;

Slope of the equation for Celinda = 36

The equation representing the total cost for Celinda is therefore;

Where c represents the cost and h represents the number of hours, we get;

c - 52 = 36·(h - 1)

c = 36·h - 36 + 52

The equation for Brian, with a slope of 38, is therefore;

c - 42 = 38·(h - 1)

c = 38·h - 38 + 42 = 38·h + 4

Part C

The cost of hiring each DJ for 5 hours is therefore;

h = 5

The cost of hiring Celinda for 5 hours is; c = 36 × 5 + 16 = 196

The cost of hiring Celinda for 5 hours is $196

The cost of hiring Brian for 5 hours can be obtained by plugging in h = 5 in the equation; c = 38·h + 4

Therefore; c = 38 × 5 + 4 = 194

The cost of hiring Brian for 5 hours is $194

Answer:

there were 13 dogs with ticks but not fleas.

Step-by-step explanation:

Let's call the number of dogs with fleas "x" and the number of dogs with ticks "y".

From the information given, we know:

x = 40 (dogs with fleas)

x + y = 75 (total number of dogs)

y = 27 (dogs with ticks)

So, the number of dogs with ticks but not fleas is equal to y - the number of dogs with both:

y - 14 = 27 - 14 = 13

Therefore, there were 13 dogs with ticks but not fleas.

To determine the price of the keyboard with the coupon, we need to know how much Tiana spent. Let's call the original price of the keyboard "x".

According to the coupon, Tiana will receive a discount of $150 for every $500 spent. So, if she spends x dollars, she will receive a discount of (x/500) * $150.

The price of the keyboard with the coupon will then be x - (x/500) * $150.

Since the original price is not specified, we cannot determine the exact price of the keyboard with the coupon.

Answer:

Problem 1: the price of one adult ticket is $8.25 and the price of one student ticket is $30.75

Problem 2: there were 10.33 students in each van and 152.67 students in each bus.

Step-by-step explanation:

Problem 1:

Let's call the price of an adult ticket as "a" and the price of a student ticket as "s". We know that on the first day the total cost was $39 and they sold 1 adult ticket and 1 student ticket, so we have the equation:

a + s = 39

And on the second day, the school took $105 from selling 9 adult tickets and 8 student tickets, so we have the equation:

9a + 8s = 105

We can use these two equations to solve for "a" and "s".

Solving for "a":

9a + 8s = 105

a - s = -39

8a = 66

a = $8.25

So the price of one adult ticket is $8.25.

Solving for "s":

a + s = 39

a = $8.25

s = 39 - 8.25 = $30.75

So the price of one student ticket is $30.75.

Problem 2:

Let's call the number of students in each van as "v" and the number of students in each bus as "b". We know that the senior classes at High School A rented and filled 2 vans and 2 buses with 326 students, so we have the equation:

2v + 2b = 326

And High School B rented and filled 11 vans and 6 buses with 233 students, so we have the equation:

11v + 6b = 233

We can use these two equations to solve for "v" and "b".

Solving for "v":

2v + 2b = 326

11v - 6b = -233

-9v = -93

v = 10.33 students in each van

Solving for "b":

2v + 2b = 326

2(10.33) + 2b = 326

20.66 + 2b = 326

2b = 326 - 20.66 = 305.34

b = 152.67 students in each bus

So there were 10.33 students in each van and 152.67 students in each bus.

The equation representing the temperature y in degrees Fahrenheit at x hours after sunset is:

Since the temperature changes linearly with time after sunset, we can represent the temperature as a linear equation:

y = mx + b

where y is the temperature in degrees Fahrenheit, x is the number of hours after sunset, m is the rate of change of temperature and b is the y-intercept.

Given that at 2 hours before sunset, the temperature is 0°F and at 2 hours after sunset, the temperature is -4°F, we can use these points to find m and b.

At x = -2: y = 0°F

At x = 2: y = -4°F

So, m = (y2 - y1) / (x2 - x1) = (-4°F - 0°F) / (2 - (-2)) = -2°F/hour

And, b = y - mx = 0°F - (-2°F/hour * -2) = 4°F
