x = 2

Step-by-step explanation: To find the time it takes Elijah to run 1 lap, we need to divide the time it takes him to run 4 laps by the number of laps he runs in that time. Since it takes Elijah 8 minutes to run 4 laps, the time it takes him to run 1 lap is 8 minutes / 4 laps = ${2}$ minutes per lap.

This calculation illustrates the concept of unit rate, which is the rate at which a quantity changes over a given unit of time or distance. In this case, the unit rate is the time it takes Elijah to run 1 lap, which is 2 minutes per lap. This unit rate allows us to compare the time it takes Elijah to run different distances, and to determine how long it would take him to run a given distance at the same pace.

Each pound of fish and chicken will cost $3.75 and $2.25 respectively

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation

Given that:

1. A customer pays a total of $11.10 for 1.6 pounds of chicken

and 2 pounds of fish.

2. Another customer pays a total of $12.15 for 2.4 pounds of

chicken and 1.8 pounds of fish

Let C and F represent the cost of one pound of chicken and fish respectively

Statement 1:

1.6C + 2F = 11.10  ---- (1)

Statement 2:

2.4C + 1.8F = 12.15  ---- (2)

we have simultaneous equations now, let's solve using the elimination method:

1.6C + 2F = 11.10      ---- (1)

2.4C + 1.8F = 12.15  ---- (2)

2.4 × (1.6C + 2F = 11.10) =     3.84C + 4.8F = 26.64

1.6 × (2.4C + 1.8F = 12.15) =  3.84C + 2.88F = 19.44

                                            ..........................................

                                                           1.92F  = 7.2

Thus, 1.92F  = 7.2

F = 7.2/1.92 = $3.75

Put F = $3.75 into (1):

1.6C + 2F = 11.10

1.6C + 2(3.75) = 11.10

1.6C + 7.5 = 11.10

1.6C = 11.10 - 7.5

1.6C = 3.6

C = 3.6/1.6 = $2.25

Answer:

  3³

Step-by-step explanation:

You want an expression using an exponent to represent the number 3·3·3.

As you know, a coefficient is used to represent repeated addition:

  a + a + a = 3a

The coefficient 3 in the above expression signifies that 'a' appears in the sum 3 times.

Likewise, repeated multiplication can be represented using a specific notation. An exponent signifies the number of times a factor appears in a product:

  a · a · a = a³ . . . . . 'a' is a factor 3 times

You have a sequence of numbers of telephone calls:

  3 the first day

  3·3 the second day

  3·3·3 the third day

The calls on the third day can be represented using an exponent:

  3³

__

Additional comment

When superscript formatting is not available for the exponent, it is signified by a caret (^). The same number is 3^3 when written in plain text.

As you might expect, a plain text exponent must be enclosed in parentheses if it is other than a single letter or number.

The number of classes per month that had same total amount paid was 21

The total amount is $115

let the number of group class be represented by x

first membership plan, Jen can pay $52 per month, plus $3 for each group class she attends

= $52 + $3x

second membership plan, Jen can pay $31 per month plus $4 per class

= $31 + $4x

when the total amount are equal

$52 + $3x = $31 + $4x

52 - 31 = 4x - 3x

21 = x

The total amount

= $52 + $3 * 21

50 tickets were thus sold at the door. As a result, there were 175 advance sales of tickets and 50 at the door.

A linear equation has the algebraic form y=mx+b. where m is the slope and b is the y-intercept, consisting of a first-order (linear) term and a constant. If x and y are variables, the above is sometimes called a "two-variable linear equation".

Tickets for a high school dance were provided.

Purchases made before the dance cost $4.00 apiece.

If purchased at the door, they would cost $5 apiece.

225 tickets were sold, bringing in $950.

It's time to locate the advance-purchase and door-purchase tickets.

Let the quantity of advance tickets sold equal x.

And the quantity of tickets sold at the door will be equal to y.

hence, the overall quantity of tickets sold

[tex]x+y = 225\\y = 225 - x[/tex]......(1)

Now,

4x + 5y = 950

[tex]4x + 5y = 950\\4x + 5(225-x) = 950\\4x + 1125 - 5x = 950\\-x = -175\\x= 175\\y=50[/tex]

As a result, there were 175 advance sales of tickets and 50 at the door.

The solution of the system of equations is y = 5 and x = 3, and the difference x - y gives:

x - y = -2

Here we have the system of equations:

5x + 3y = 30

-5x - 2y = -25

If we add the two equations we will get:

(5x + 3y) + (-5x - 2y) = 30 + (-25)

y = 5

So just by doing that we found the value of the variable y.

To find the value of x, we can replace the known value of y on one of the equations, doing that we will get:

5x + 3y = 30

5x + 3*5 = 30

5x + 15 = 30

5x = 30 - 15 = 15

x = 15/5 = 3

x = 3

By using the concept of function, it can be seen that the given figure does not represents a function.

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here the values on the x axis represents the domain and the values on the y axis represents the Range.

From the figure it can be seen that

For x = 2, there are three points on the y axis.

So the point x = 2 maps to different points on the y axis

The angles BAX and CDX are equal and the length of CX is 8.2 cm.

What are angles?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

Given that, the points A, B, C, D lie on a circle and AC and BD intersect at X.

The angles BAX and CDX, they are subtended by the same arc AD, hence, according to the property of angles subtended by the same arc, they are equal.

Thus ∠BAX = ∠CDX

Since, corresponding sides opposite to the equal angles are proportional.

CX/BX = CD/AB

⇒ CX/3.84 = 9.40/4.40

⇒ CX = (9.40*3.84)/4.40

⇒ CX = 8.2

Thus, length of CX is 8.2cm

The angles BAX and CDX are equal and the length of CX is 8.2 cm

What is sinusoidal wave?

A mathematical curve defined in terms of the sine trigonometric function, of which it is the graph, is known as a sine wave, sinusoidal wave, or simply sinusoid. It is a smooth periodic function and a particular kind of continuous wave.

Let the graphs of y = cos(x) and y = cos(x/2) are given.

From this graphs we have to find the value of c and d.

First from y = cos(x) to find the value of 'a'.

Consider, the point  [tex](a, \frac{1}{8})[/tex]

⇒

[tex]cos(a) = \frac{1}{8} \\a = cos^-^1(\frac{1}{8})\\ a = 82.82[/tex]

Now to find the value of 'c'.

Plug a = 82.82 in y = cos(x/2).

[tex]cos(\frac{82.82}{2}) = c \\c = -0.84[/tex]

Hence, the value of 'c' is 'c = -0.84'.

Now to find the value of 'd'.

Consider, the point [tex](b, \frac{1}{8})[/tex]

⇒

[tex]cosb = \frac{1}{8} \\b = cos^-^1(\frac{1}{8})\\b = 82.82[/tex]

Now, plug b = 82.82 in y = cos(x/2)

[tex]cos(\frac{82.82}{2}) = d\\ d = 0.84[/tex]

Hence, from the given graphs the values of 'c' and 'd' are c = -0.84,

d = 0.84.
