Answer:
144 employees
Explanation:
• The ratio of men to women = 3:5
,• The number of men in the company = 54.
Let the total number of employees = x.
The proportion of men in the company will be:
[tex]\frac{3}{3+5}=\frac{3}{8}[/tex]Since there are 54 men in the company, we can then say that:
[tex]\begin{gathered} \frac{3}{8}\text{ of x}=54 \\ \implies\frac{3}{8}x=54 \end{gathered}[/tex]Multiply both sides by 8/3 to solve for x.
[tex]\begin{gathered} \frac{8}{3}\times\frac{3}{8}x=\frac{8}{3}\times54 \\ x=144 \end{gathered}[/tex]The total number of employees is 144.

Lincoln went into a movie theater and bought 2 bags of popcorn and 4 candies, costing a total of $34. Zoey went into the same movie theater and bought 6 bags of popcorn and 5 candies, costing a total of $74. Determine the price of each bag of popcorn and the price of each candy.
Answers
12 each bags
Step-by-step explanation:
2x +4y =34
6x +5y =74
x =34- 4y ÷2
y = $3
x= $ 11
bag each price is $11
The price of one bag of popcorn is $9 and the price of one candy is $4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Let the price of 1 bag of popcorn = x
And price of 1 candy = y
Given that,
Lincoln buys 2 bags of popcorn and 4 candies for $34
implies that,
2x + 4y = 34 (1)
Also, Zoey buys 6 bags of popcorn and 5 candies for $74
implies that,
6x + 5y = 74 (2)
By solving equation (1) and (2),
x = 9 and y = 4
The price of one bag of popcorn is $9 and the price of one candy is $4.

Finds the measures of angle b and d given that m ll n. Explain.
Answers
Answer:
b = 60.7
d = 43.1
Explanation:
The angles of measure 60.7 and b are alternate interior angles because they are on opposite sides of the transversal and in the inside of the parallel lines m and n. These angles have the same measure, so
b = 60.7
Angle d and the angle of measure 136.9 form a straight line, so they sum to 180 degrees. Therefore, the measure of angle d is
d = 180 - 136.9 = 43.1
Therefore, the answers are
b = 60.7
d = 43.1
The Elimination MethodTry These BSolve each system using elimination.a. 7x+5y=-14x - y=-16
Answers
Elimination Method : In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
The given system of equation:
7x + 5y = -1 (1)
4x - y = -16 (2)
Multiply the equation (2) by 5 :
5(4x -y ) = 5(-16)
20x - 5y = -80 (3)
Add equation (3) & (1)
(7x + 5y) + (20x -5y ) =(-1) + (-80)
7x + 5y + 20x - 5y = -1 - 80
27x = -81
x = -81/ 27
x = -3
Substitute the value of x =3 in the equation (1)
7x + 5y = -1
7(-3) + 5y = -1
-21 + 5y = -1
5y = -1 +21
5y = 20
y =20/5
y = 4
Thus, the solution of system is (x, y) = (-3, 4)

The given equation is a quadratic equation. Recall, the standard form of a quadratic equation is expressed as
ax^2 + bx + c = 0
The given equation is
x^2 - 8x = - 128
By adding 128 to both sides of the equation, we have
x^2 - 8x + 128 = - 128 + 128
x^2 - 8x + 128 = 0
By comparing this equation with the standard form equation,
a = 1, b = - 8, c = 128

Answers
Explanation:
A relation is a function if and only if there is one value of x for different values of y.
This means that if we see repeated x-values then it's not a function. We can see this clearly in the graphs by drawing a vertical line for the values of x. Of the line crosses the graph more than once, then it's not a function.
In every graph the line crosses the graph more than once, so none of these options are functions.
Then, for a set of points we have to check the x-coordinate of each pair. If one repeats in the set, then it's not a function.
In the relation E x = -5 is repeated, so it's not a function. On the other hand, for relation D none of the x-coordinates are repeated. Therefore relation D IS a function
Answer:
Option D is a function
