The pair of equivalent expression are 6(8f) and 48f
What is equivalent expression?Equivalent expressions are expressions that have similar value or worth but do not look the same.
Two expressions are said to be equivalent if they have the same value
irrespective of the value of the variable(s) in them.
Therefore, let's check the pair of expression and find which are equivalent.
6(8f) and 48f are equivalent expression.
If we simplify 6(8f), it will be as follows:
6(8f) = 6 × 8f = 48f

How to Graph 2x-3y=6 in a coordinate plane.
Answers
Explanation:
To graph the equation 2x - 3y = 6, we need to find two points in the line.
So, first let's make y = 0 and solve for x
2x - 3y = 6
2x - 3(0) = 6
2x = 6
2x/2 = 6/2
x = 3
Then, if x = 0, we get:
2x - 3y = 6
2(0) - 3y = 6
-3y = 6
-3y/(-3) = 6/(-3)
y = -2
Therefore, the points that we will use to graph the equation are (3, 0) and (0, -2).
Answer:
So, the graph of 2x - 3y = 6 is

7. How many prime factors does the number 124 have?
Answers
It a popular math theorem, that any natural number can be factored out into prime numbers. For example the number 24 is factored as 2³*3, so its prime factors are 2 and 3.
In this case, we want to factor 124. We start by noticing that 124 is an even number, therefore, the first prime factor we try is 2. Next, we divide 124 by 2. We get
[tex]\frac{124}{2}=62[/tex]which is again an even number. This means that we can again divide by 2. We do so
[tex]\frac{62}{2}=31[/tex]Note that 31 is a prime number. So we can't continue dividing. Then
[tex]124=2\cdot2\cdot31=2^2\cdot31[/tex]So it has 2 different prime factors

Answers
According to the situation, the domain of this function will contain all values that x can take. Since x is the number of items, it only can take values from 0 to a certain value.
To find this certain value, use the maximum cost allowed (2700) as C(x) and find x using the equation:
[tex]\begin{gathered} C(x)=10x+700 \\ 2700=10x+700 \\ 2700-700=10x \\ 2000=10x \\ x=\frac{2000}{10} \\ x=200 \end{gathered}[/tex]It means that the domain of the function is [0,200]
The range contains all the values that cost can take. We know that the fixed cost (which is the minimum cost) is 700 and the maximum cost is 2700.
It means that the range of the function is [700,2700]

Answers
Given the two circles shown in the exercise, you need to remember that, by definition, two figures are congruent when they have the same size and they have the same shape.
In this case, you can identify that the circles have the same diameters (remember that a diameter of a circle is the length that passes through the center of the circle and touch two points on the circumference):
[tex]\begin{gathered} d_1=2units \\ d_2=2units \end{gathered}[/tex]Therefore, these circles have the same shape and size.
By definition, two figures are similar when their corresponding angles are congruent and the ratios of the corresponding sides are proportional.
In this case, since the figures are circles, you know that they both measure 360 degrees. Knowing that they also have the same diameter, you can determine that they are similar too.
Hence, the answer is: They congruent and similar.

A new auditorium is being built for a college. The balcony has 60 seats. Thefloor has 15 rows with x seats in each row. The number of people in theauditorium must be under 315 to meet safety regulations.What is the solution of this inequality, and what is its meaning?
Answers
x < 17
This means the new auditorium must have less than 17 seats 1n each row on the floor to meet the safety regulations.
Explanation:Number seats in the balcony = 60
Number of seats on the floor = number of rows × number of seats on each row
Number of seats on the floor = 15× x = 15x
The number of people in the auditorium must be under 315:
This means the number of people can be less than 315 but not above it.
We represent less than 315 as < 315
The inequality equation:
Number seats in the balcony + Number of seats on the floor < 315
60 + 15x < 315
Rewritting the inequality equation:
15x + 60 < 315
Solving the inequality:
15x + 60 < 315
collect like terms by subtracting 60 from both sides:
15x + 60 - 60 < 315 -60
15x < 255
Divide both sides by 15:
15x/15 < 255/15
x < 17
This means the new auditorium must have less than 17 seats in each row on the floor to meet the safety regulations.

Given:
The doctor gave the mother of the sick baby 16 fl oz bottle of liquid medicine.
Dosage instructed to give the baby = 30 ml twice a day
a) How many tablespoon is one dose?
Using standard measurements, 1 tablespoon = 15 ml
Since 1 dose is 30 ml, the dose in tablespoon is:
[tex]\frac{30\text{ ml}}{15\text{ ml}}=\text{ 2 tablespoons}[/tex]1 dose is 2 tablespoons
b) Since, 30 ml is to be given 2 times daily, the ml the child will take a day is:

What is equations?There are many different ways to define an equation.The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.A linear equation may have more than one variable. A linear equation is an equation in which the highest power of the variable is always 1.This is a second-order equation. In quadratic equations, at least one of the variables should be raised to exponent 2.According to our question-
Total SA of a cone = πr^2+πrl = πr(r+l)

The measurement of three angles of a triangle are (2x)degrees ,(3x)degrees and (x+30) degrees. What is the value of x?
Answers
We have that the measurement of three angles of a triangle is:
1. Angle 1: 2x degrees.
2. Angle 2: 3x degrees.
3. Angle 3: (x+30) degrees.
We know that the sum of the internal angles of a triangle is equal to 180.
Therefore, to find the value of x, we can proceed as follows:
[tex]\begin{gathered} m\angle1+m\angle2+m\angle3=180^{\circ} \\ \\ 2x+3x+(x+30)=180^{\circ} \end{gathered}[/tex]Now, we can add the like terms as follows:
[tex]\begin{gathered} 2x+3x+x+30^{\circ}=180^{\circ} \\ \\ 5x+x+30^{\circ}=180^{\circ} \\ \\ 6x+30^^{\circ}=180^{\circ} \end{gathered}[/tex]We can subtract 30 degrees to both sides of the equation, and then we have to divide both sides by 6:
[tex]\begin{gathered} 6x+30^{\circ}-30^{\circ}=180^{\circ}-30^{\circ} \\ \\ 6x=150^^{\circ} \\ \\ \frac{6x}{6}=\frac{150}{6} \\ \\ x=25 \end{gathered}[/tex]Therefore, in summary, the value for x is equal to 25.
