What is  number ?

A number is an arithmetic value that is used to calculate and represent a quantity. Numerical symbols, such as "3," are written to represent numbers. A number system is a logical way of expressing numbers that uses digits or symbols to represent them.

At Jefferson High School, there are 250 students who drive to school and 375 students who ride the bus to school. The number of students who drive to school is

=375-250

=125

Answer: 178.25

Step-by-step explanation:

124.25 + 223.56 - 89.56 - 80.00

Answer: $178.25

Step-by-step explanation: Your balance on May 15 is $124.25. On May 20, you deposit $223.56, which increases your balance to $124.25 + $223.56 = $347.81. You then write a check for $89.56, which decreases your balance to $347.81 - $89.56 = $258.25. Finally, you withdraw $80.00 from an ATM on May 25, which decreases your balance to $258.25 - $80.00 = $178.25. Therefore, your current balance is $178.25.

A small airplane can fly about 124.8 miles in one hour.

In this question, we have been given a small airplane flew 104 miles in 50 minutes.

We need to find the distance the airplane would cover in an hour.

Let a small airplane can fly 'x' miles in one hour.

We know that 1 hour = 60 minutes

Using proportionality we get an equation,

x/104 = 60/50

We solve above equation.

50x = 60 * 104

x = 6240/50

x = 124.8

So, the distance would be 124.8 miles

Therefore, an airplane can fly 124.8 miles in an hour.

Step-by-step explanation:

When Akbar is 9 years older than Yasir and Hamid is 2 years younger than Yasir then, the expression for their sum of ages is 3x+7

A linear equation is a mathematical equation that describes a straight line. It is a first-degree polynomial equation, which means that the largest exponent of the variables is 1. Since a and b are constants and x and y are variables, linear equations have the general form ax+by=c. A straight line forms on a coordinate plane when the values of x and y fulfil the expression. The connection between two variables or the price of a product are two examples of real-world events that are frequently modelled using linear equations. Solving a linear equation entails determining the values of the variables that make the equation true. Different techniques, such graphing, substitution, or elimination, can be used to accomplish this.

How to solve?

Let x be Yasir's age

Akbar is x+9

Hamid is x-2

The sum of their ages is x+(x+9)+(x-2)

=3x+7

The area of the resulting shape if a circle with a 12-inch diameter is folded in half and then folded in half again is 28.26 square inches

If a circle with a 12-inch diameter is folded into half and then folded into half again the circle will become a quadrant.

So,

The area of a quadrant is area of a circle divided by 4

Area of a quadrant = πr² / 4

Diameter of a circle = 2r

12 = 2r

divide both sides by 2

r = 6 inch

Area of the quadrant = 3.14 × (6)²/4

Area of the quadrant = (3.14 × 36) /4

Area of the quadrant = 113.04 / 4

Area of the quadrant = 28.26 square inches

In conclusion, the area of the quadrant is 28.26 square inches

The solution to the system of equations is (d) (-2, 1)

From the question, we have the following parameters that can be used in our computation:

y = 2x + 5

y = -1/4x + 0.5

Substitute y = 2x + 5  in the equation y = -1/4x + 0.5

So, we have the following representation

-1/4x + 0.5 = 2x + 5

Collect the like terms

So, the equation becomes

2x + 1/4x = 0.5- 5

So, we have

2.25x = -4.5

Divide by 2.25

x = -2

Substitute x = -2 in y = 2x + 5

y = 2 x -2 + 5

y = 1

Hence, the solution is (d) (-2, 1)

The required number solutions of given quadratic equation is -1 or 5/2.

A quadratic equation in math is a second-degree condition of the structure ax^2 + bx + c = 0. Here a, b, are the coefficients, c is the steady term, and x is the variable. Since the variable x is of the subsequent degree, there are two roots or deals with this quadratic condition.

We have,

x-1/x+1=3/2x+2

(x - 1)(2x + 2) = 3(x + 1)

2x^2+2x-2x-2 = 3x+3

2x^2-3x-5 = 0

2x^2-5x+2x-5 = 0

If the perimeter is less than 20, then the inequality is:

Answer:

x < 4

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

Therefore, from inspection of the triangle:

⇒ Perimeter = 4 + 9 + x + 3

⇒ Perimeter = x + 16

If the perimeter is less than 20 meters then:

⇒ x + 16 < 20

Solve the inequality:

⇒ x + 16 - 16 < 20 - 16

[tex]122.5[/tex]

Step-by-step explanation:

[tex]circumference \: = 2\pi \:r[/tex]

[tex]\pi = 3.14[/tex]

[tex]r = 19.5[/tex]

Replacing:

[tex]2 \times 3.14 \times 19.5 = 122.46[/tex]

Therefore, final answer[tex] = 122.5[/tex](to the nearest tenth)

The answer is 122.5

In the given question, we have given the radius of the circle and we need to find the circumference of the same.

To need to find the circumference, we must recall this formula

Circumference of circle = [tex]2\pi r[/tex]

Now, according to the question

Radius = 19.5 cm

Circumference = 2 * [tex]\pi[/tex] * 19.5

                         = 2 * 3.14 * 19.5       (Taking [tex]\pi[/tex] = 3.14)

                         = 122.5 cm

Therefore, the circumference of a circle with radius 19.5 cm is 122.5 cm

On rounding off the answer to the nearest tenth, it remains the same.

Hence, the final answer to the question is 122.5 cm.

The equation that used to determine the dimension is 2(2x+10) = 300 and the dimensions of the rectangular yard is 80 foot and 70 foot

Total length of the fence = 300 foot

Consider the width of the rectangular yard = x

The length of the rectangular yard = x + 10

The perimeter of the rectangle = 2(l + w)

Where l is the length and w is the width

Substitute the values in the equation

300 = 2(x+10 + x)

300 = 2(2x + 10)

4x + 20 = 300

4x = 300 - 20

4x = 280

x = 280/4

x = 70 foot

You should cast a shadow for a person or item at least three times and measure it each time to determine how the length of the shadow varies during the day.

The shape of an object always dictates the shape of its shadow. A shadow's size and shape can alter, though.

For instance, the location of the light source can induce these variations. The length of the shadow is influenced by the sun's position in the sky on a sunny day.

We can achieve the same effect indoors by adjusting the position of a flashlight reflecting on an object.

When the sun is low on the horizon, the shadows are lengthy, and when the sun is high, the shadows are considerably shorter.

So, To determine the change of length of object during the day, one should cast a shadow at least three separate times for a person or object and measure it each time

For the function, y = log₄ (x + 16) - 1, it has x-intercept of -12 and y-intercept of 1.

Logarithmic functions are functions expressed in another way for exponential functions. It is the power to which any number should be raised to yield other values.

Logₐ x = n can be written in exponential form as x = aⁿ.

y = log₄ (x + 16) - 1

x-intercept is the x-coordinate of the point when y = 0.

0 = log₄ (x + 16) - 1

For the left hand side to be equal to 0, the term log₄ (x + 16) must be equal to 1.

log₄ (x + 16) = 1  

⇒ x + 16 = 4       (∵ logₐ a = 1)

⇒ x = -12

y-intercept is the y-coordinate of the point where x = 0.

y = log₄ (0 + 16) - 1

y =  log₄ (16) - 1

y =  log₄ (4²) - 1

logₐ mⁿ = n logₐ m

⇒ y = 2 log₄ (4) - 1

⇒ y = 2 - 1     (∵ log₄ (4) = 1)

⇒ y = 1

Hence, the function y = log₄ (x + 16) - 1 has x-intercept of -12 and y-intercept of 1.

What is an isosceles triangle?

An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.

3x - 5 = y + 12  (if two angles of a triangle are equal, the sides opposite                    

                          them are also equal)   ------------(1)

Also, 3x - 5 = 5y - 4     (sides of a equilateral  triangle are equal)

So,  5y - 4 = y + 12

       5y - y = 12 + 4

         4y = 16

           y = 4

Now,

Put value of y in equation (1)

3x - 5 = y + 12

3x = 4 +12 + 5

3x = 21

x = 7

Hence, x = 7 and y = 4
