According to the above, to draw a 1:2 scale we must divide the figure in 2.

The scale model is a way of drawing a figure that is smaller or larger in size. In this case, the size would be smaller, 1:2 means that for each unit of measurement (cm) of the original figure, there are 2 units on the scale.

According to the above, if the circle has a 12cm radius, then the scale model would have a 6cm radius, that is, it would be smaller than the original as shown in the second image.

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.

Answer:

To subtract the two mixed numbers, we need to convert both mixed numbers to improper fractions.

So,

8/9 = 72/81 (by multiplying both numerator and denominator by 9)

and

4/6 = 40/60 = 2/3 (by multiplying both numerator and denominator by 10/10)

So,

72/81 - 2/3 = (72 * 3 - 2 * 81) / (81 * 3) = (216 - 162) / 243 = 54/243.

So,

8/9 - 4/6 = 54/243.

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.

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]

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:

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

Now, 3x + 4y = 36
3(8) + 4y = 36
4y = 36 - 32 = 4

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.

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

y = -2x + 4

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
