Advanced tickets(x): $15

Same day tickets(y) : $30

For one more performance there are 55 tickets sold

x+ y= 55 (a)

The total amount paid for them was 1275

15x+30y= 1275 (b)

System of equations:

x+y= 55 (a)

15x+30y = 1275 (b)

Solve for x in (a)

x=55-y

Replace x on (b)

15(55-y)+30y = 1275

The amount of money that Abdul is going to donate to the City Youth Fund is denoted by x, and the amount of money that Abdul is going to donate to the Educational Growth Foundation is denoted by y.

Since Abdul will donate up to $500, the sum of those amounts must be less or equal to 500.

It is not possible to donate less than zero, therefore, we also have the following constrains

Abdul wants the amount of money donated to the Educational Growth Foundation to be at least 4 times the amount of money donated to the City Youth Fund, therefore, we have our final constrain

Combining those four regions, the solution is their interception, which is

a number that can be written as the ratio of two integers (option B)

Irrational number cannot be written in the fractional form

Rational numbers can be written in the form of fraction

Checking the options:

a) Circumference = πd

where d = diameter

π = Circumference/diameter

π is an irrational number

b) A number written as ratio of two intergers can be written in the form of fraction

Hence, it is rational

c) A number that we can use in solving an algebraic equation can be any real number.

From a real number, we have rational and irrational numbers. So, there is the likelihood we get an irrational number

d) side of a square = a

diagonal² = a² + a²

length of diagonal of a square = √(a² + a²) = √2a²

This can also yield either irrational or rational numbers.

A number that cannot be irrational means a number that is rational.

From the option, the only one without doubt that it is rational is a number that can be written as the ratio of two integers (option B)

Answer:

Step 1 of 2:
-26x - 5 = x - 56

Step 2 of 2:
17/9   or 1.89

Step-by-step explanation:

1. Putting word statement in algebraic form

Step 1:
Let x be the unknown number ==> x is the unknown variable to be used in the equation and to be solved for

Step 2:
-26 times a number minus 5 ==> -26x - 5

Step 3:
is equal to 56 less than the number  ==> = x - 56

Putting it all together:
-26x - 5 = x - 56

2. Solving the equation
-26x - 5 = x - 56

1. Subtract x from both sides:
-26x - 5 - x = x - x  -56

-26x -x - 5 = -56

-27x - 5 = -56

2. Add 5 to both sides
-27x - 5 + 5 = -56+ 5

-27x = -51

x = -51/-27   (dividing both sides by -27)

x = 51/27    (negative divide by negative results in positive)

Reduce 51/27 by dividing numerator and denominator by 3

x = (51 ÷ 3)/(27 ÷ 3) = 17/9

= 1.88888.... = 1.89 rounded to two decimal places

Perpendicular line are reciprocals

slope of the original line = -1/9

slope of the perpendicular line = 9

A line can be written as an equation in the slope-intercept form:

Where m is the slope and b is the y-intercept.

We know the slope:

The y-intercept is the y value of the graph where it intercepts the y-axis, which happens when x = 0.

We know that the point x = 0 and y = 3 is on the line and, since the value of x is 0. the y value is the y-interceot, so:

Thus, we have the equation:

To calculate the other points, we just need to substitute their x values and get their y values:

x = 1:

So, when x = 1, y = 6

x = 2:

So, when x = 2, y = 9.

x = 3:

So, when x = 3, y = 12;

So, the complete table is:

x | 0 | 1 | 2 | 3

y | 3 | 6 | 9 | 12

Answer:

Rate of the faster group = 3.38 miles per hour

Rate of the slower group = 1.88 miles per hour

Explanation:

Let x = rate of the slower group

Therefore the rate of the faster group will be x + 1 1/2 = x + 3/2 = x + 1.5

From the question, we're told that the two groups traveled for a total hiking time of 200 hours.

We know that distance = rate x time

So the distance of the slower group will be = 200x

And the distance of the faster group will be = 200(x + 1.5)

So if the distance between each town is 1050, we can then solve of x as shown below;

Therefore the rate of the faster group = 1.88 + 1.5 = 3.38 mph.

Answer:

c. you can't be feeling alive with wearing,weakness of body and mind.

In the expression 3/3=_/21, it can be observed that 7 is multipled by denominator 3 in order to obtain 21 in in denominator. So same number, 7 is also multiplied with the numerator also.

So, 21 is to be filled at blank space.

To answer this question we need the equation of a parabola that uses the distance from the focus to the vertex.

This formula is,

where,

p is the distance from the focus to the vertex, and the point (h,k) is the vertex.

Let us now substitute the data into the equation of the parabola,

Hence, the equation for the parabola is, x² = 8y.

Option C is the correct answer.

The probability that we do not dealt a card with number 2 to 9 is 5/13

What is Probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given,
A pack of card = 52 cards

The Cards having Hearts = 13

The Cards having Spade = 13

The Cards having Diamond = 13

The Cards having Clubs = 13

According to question

The cards numbered from 2 to 9 are 8 cards, specifically 2, 3, 4, 5, 6, 7, 8, and 9.

But there are four suits:  diamonds, hearts, spades, and clubs.

Therefore you multiply 8 by 4 to get 32

The probability of getting dealt one of those cards would be:

32/52, or

8/13

But we have to find the probability of not getting such cards

Thus,

1 - 8/13 = 5/13

Hence,  the probability that you are not dealt a card with number from 2 to 9 will be 5/13

We are given the following equation of a line.

Let us first solve the above equation for x.

Divide both sides of the equation by -2

So, the solution is x = 0

This means that the two ordered pairs must contain the x-coordinate 0 and the y-coordinate can be any value you like.

Answer

Options A and C are correct.

The triangle is a Scalen triangle and it is also an Acute triangle.

Explanation

To answer this question, we first explain what these type of triangles are

According to side lengths,

- Scalene triangle has none of its three sides having the same length as another. All the three sides have different lengths. To use angle to know this, all the three angles of a Scalene triangle have different values.

- Isoscelles triangle has two of its sides with the same lengths. In terms of angles, an Isoscelles triangle has two of its angles equal to each other.

- Equilateral triangle has all of its sides equal to one another. In terms of angles, all of the angles of an Equilateral triangle are equal to one another. Each of the angle is equal to 60°.

According to the angles,

- Acute triangle has all of the angles in the triangle being less than 90 degrees.

- Right angle triangle has one of the angles in the triangles being equal to 90 degrees.

- Obtuse triangle has one of the angles in the triangle being greater than 90 degrees but obviously less than 180 degrees.

For this triangle,

We can see that all of its sides have different lengths. Hence, the triangle is a Scalene triangle.

Also, each of the angles of the triangle is less than 90 degrees. Hence, the triangle is an Acute triangle.
