Answers

Answer 1

The system of the equation is written as

x + y = 428

5x + 3y = 1674

the solution:

adult tickets is 195

students tickets is 233

How to write the required equation

The problem is a simultaneous equation of two unknowns with two equations.

The equations are formed as follows

Janine sold 428 tickets for the school play

let the adult ticket be x and student ticket be y

x + y = 428

Janine’s total ticket sales were $1674

Student tickets were $3 and adult tickets were $5

5x + 3y = 1674

The simultaneous equation

x + y = 428

5x + 3y = 1674

solving the equation  by elimination method

x + y = 428 * 3

3x + 3y = 1284

5x + 3y = 1674

subtraction gives

-2x = -390

x = 195

substitute x = 195 into x + y = 428

195 + y = 428

y = 428 - 195

y = 233

hence adult tickets is 195, while students tickets is 233

Find the coordinates of B, C, and D given that AB = 5 and BC

= 10.

Answers

The coordinates of B, C, and D are (3,-5), (3,5), and (-7,5) respectively.

Given point A (-2,-5) and the lengths of the sides AB = 5 and BC = 10, we can use this information to determine the coordinates of B, C, and D.

Using the information provided, we know that B is 5 units away from A in the positive x-direction. Therefore, the x-coordinate of B is (-2) + 5 = 3 and the y-coordinate of B is the same as that of A, which is -5. So point B is (3,-5).

Next, we know that C is 10 units away from B in the positive y-direction. Therefore, the x-coordinate of C is the same as that of B, which is 3, and the y-coordinate of C is (-5) + 10 = 5. So point C is (3,5).

Finally, we know that D is 10 units away from C in the negative x-direction. Therefore, the x-coordinate of D is 3 - 10 = -7 and the y-coordinate of D is the same as that of C, which is 5. So point D is (-7,5).

A. Find 25% of $120 is this the price he will pay? B. Does Wyatt have enough

Answers

25 percent of $120 is $30 and yes, he has enough money to buy the music player.

A) Find 25% of $120:

To find 25% of $120, we divide $120 by 100 and then multiply by 25:

$120 / 100 * 25 = $30

So, 25% of $120 is $30.

B) Does Wyatt have enough:

To find the sale price of the music player, we need to apply the 24% discount:

$120 - $120 * 24% = $120 - $120 * 0.24 = $120 - $28.80 = $91.20

So, the music player will be sold for $91.20.

Marvin should put at least $45 more cash in his wallet in order to have at least $60.

Solving inequality questions

Let x be the amount of cash that Marvin needs to put in his wallet. We know that he wants to have at least $60, and he currently has $15, so we can write the inequality as:

x + 15 ≥ 60

To solve for x, we need to subtract 15 from both sides of the inequality:

x ≥ 60 - 15

x ≥ 45

The path of a fast moving particle traces a circle with equation (x-3)² + (y-4)² = 25. It starts at point (3,-1), moves counter clockwise, and passes the point (8,4) for the first time after traveling 7 microseconds. Where is the particle after traveling for 20 microseconds. ​

Answers

The particle is at the point (-1.112,3.909) after traveling for 20 microseconds.

We have been given a circle,

(x-3)²+(y-4)²=25

whose center is (3,4)

and with a radius of 5 units.

The particle starts at (3,-1) which is the 6 o'clock position in the circle, and ends at (8,4) after 7 microseconds which are at the 3 o'clock position in the circle.

So, the particle traveled 1/4 of the circumference of the circle in 7 microseconds

therefore according to the unitary method it will travel 5/7 of the circumference of the given circle.

so it will subtend 2π×5/7 of the circle from (3,-1)

from the polar form of the circle and the shifting of center of the circle we can conclude

that it's location will be

The best interpretation of 14.2 as shown in the equation above is the constant acceleration of the airplane.

What is the constant acceleration?

A particle's acceleration is the rate at which its velocity changes over time. The term "constant acceleration" refers to the rate at which a particle's velocity changes. When acceleration is constant, the rate of change in velocity is also constant. In the absence of any acceleration, velocity remains constant.

When acceleration is positive, velocity becomes more significant. Acceleration causes a decrease in velocity.

consider the random variable that assigns the number 0 to red and white, the number 1 to green and blue, and the number 2 to yellow and violet. what is the distribution of this random variable?

Answers

     A variable whose value is decided by a random process or experiment is known as a random variable.

    Depending on how the experiment or random process turns out, it may have a range of distinct numerical values. Random variables come in two varieties: discrete and continuous. A continuous random variable can take on any value within a specific range, such as real numbers, but a discrete random variable can only take on a countable number of values, such as integers.

This random variable has the following distribution and is discrete in nature:

P(X=0) = probability of red or white = P(red) + P(white)

P(X=1) = probability of green or blue = P(green) + P(blue)

P(X=2) = probability of yellow or violet = P(yellow) + P(violet)

P(X=x) must have a sum of all possible values of 1, which indicates that

   P(red) + P(white) + P(green) + P(blue) + P(yellow) + P(violet) = 1

    Therefore ,with a probability  of 1/3 for each value, this random variable has a discontinuous uniform distribution over the set of values 0, 1, and 2.

The ratios between both the two variables should be considered in order to determine whether a relationship is proportional. The relation is proportional if the ratio remains constant. The relationship is indeed not proportional if the ratio shifts.

What are the two proportional relationships principles?

When two or more items are directly proportionate or change in size according to equivalent ratios, the relationship is said to be proportional. This proportional relationship can be expressed using the formula y = kx.

Step-by-step explanation:

Joel needs to make 200 milliliters of a solution that is 35% sulfuric
acid for science class.
In the cabinet there is a 15% sulfuric acid solution and a 55% sulfuric
acid solution.
How much of the 15% solution and how much of the 55% solution
does Joel need?
Round to the nearest milliliter if necessary.

Answers

The amounts of each solution are given as follows:

15% solution: 100 milliliters.55% solution: 100 milliliters.

How to obtain the amounts?

The amounts are obtained solving a system of equations, for which the variables are given as follows:

Variable x: amount of the 15% solution.Variable y: amount of the 55% solution.

Joel needs to make 200 milliliters, hence:

x + y = 200.

x = 200 - y.

The rate is of 35%, hence:

0.15x + 0.55y = 0.35 x 200

0.15x + 0.55y = 70.

The solution for y is given as follows:

0.15(200 - y) + 0.55y = 70

0.4y = 40

y = 40/0.4

y = 100.

The solution for x is given as follows:

x = 200 - y

x = 100.

A square painting has a diagonal of 44 in. Lorraine wants to frame the picture. The framing material is sold by the inch.


What is the minimum amount of framing she needs?

Answers

The minimum amount of framing Lorraine needs for the square painting is 31 inches.

We can use the Pythagorean theorem to calculate the length of the side of the square given the length of its diagonal. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

We know that the diagonal of the square painting is 44 inches, and since the diagonal of a square bisects its angles, the square can be divided into two congruent right-angled triangles. Therefore, the length of one side of the square can be calculated using the Pythagorean theorem:

44 inches^2 = x^2 + x^2

x^2 = 11*11

x = 11 inches

Since the square painting has a side length of 11 inches, and the framing material is sold by the inch, Lorraine will need a minimum of 11 inches of framing on each side, for a total of 44 inches.

Which function represents the reflection over the x-axis of f(x)=x

Answers

The reflected function is the one below:

g(x) = -√x

This function is represented by the last table.

Which one represents the reflected fucntion?

For a general function y = f(x), we define a reflection over the x-axis as:

g(x) = -f(x)

In this case f(x)=  √x, then the reflected function will be:

g(x) = -f(x) = -√x

Now we can evaluate this function to get some pairs of values.

Then when x = 1

g(1) = -√1 = -1

g(2) = -√2 = -1.41

And so on.

Then the correct option is the last table.

The equation of the trend line, can be found to be y = - 25 + 250

How to find the equation of the trend line ?

To find the equation of the trend line, you first need to find the slope. To do this, pick two points on the trend line. ( 4, 150) and ( 8, 50 ).

The slope is:

= ( Y2 - Y1 )/ ( X 2 - X 1 )

= ( 50 - 150 ) / ( 8 - 4 )

= - 100 / 4

= - 25

The equation of the trend line takes the form:

y = mx + b

m = slope

b = y - intercept

The slope allows you to find the y - intercept :

y = mx + b

50 = - 25 ( 8 ) + b

b = 250

The equation is:

y = - 25 + 250

You are the manager of a small store that specializes in hats, sunglasses, and other accessories. You are considering a sales promotion of a new line of hats and sunglasses. You will offer the sunglasses only to those who purchase two or more hats, so you will sell at least twice as many hats as pairs of sunglasses. Moreover, your supplier tells you that, due to seasonal demand, your order of sunglasses cannot exceed 100 pairs. To ensure that the sale items fill out the large display you have set aside, you estimate that you should order at least 210 items in all. Assume that you will lose $3 on every hat and $2 on every pair of sunglasses sold. Given the constraints above, how many hats and pairs of sunglasses should you order to lose the least amount of money in the sales promotion?
