Muskco gave 88 people a bonus. If Muskco had given 4 more people bonuses, Muskco would have rewarded 2 over 3of the work force. How large is Muskco's work force
The amount of Muskco's work force that he has in his business is; 138 people
How to solve Algebra Word Problems?We are told that Muskco gave 88 people a bonus. Now, we are further told that if he had given 4 more people bonuses, then it means he would have rewarded two thirds of his workforce.
Thus we can begin too solve this problem to find the size of Muskco's work force by;
Let the total number of his workforce be denoted as x. Then the algebraic equation for this problem would be expressed as;
88 + 4 = (2/3)x
Simplify by adding up the left hand side values to get;
(2/3)x = 92
Use multiplication property of equality to Multiply both sides by 3 to get;
2x = (92 * 3)
2x = 276
Now, use division property of equality to divide both sides by 2 to get;
2x/2 = 276/2
x = 138
Thus, we would conclude from the calculations as seen in the above that the size of Muskco's workforce is 138 people.

This is further explained below.
What is a parallelogram?A parallelogram is a basic quadrilateral in Euclidean geometry that has two pairs of sides that are parallel to one another.
The sides that are perpendicular to one another, also known as facing sides, of a parallelogram, have the same length, and the angles that are perpendicular to one another have the same measure.
In most cases, a parallelogram will have two sets of parallel opposing sides. The angles that are diagonal to it are likewise equal.
When angle A is given as 79 degrees and the parallelogram ABCD is used, the remaining angles may be obtained as follows:
Angle A is diametrically opposed to angle C.
[tex]\angle A$ is opposite to $\angle C \\\\\angle A=\angle C \\\\\angle C=79^{\circ}[/tex]
Hence ∠C=79°
Because it is a parallelogram, the two remaining angles are complementary to one another and have the same degree:

as a percentage of the price before the increase?
The new amount as a percentage of the price before the increase is =[tex]\frac{118.2x}{100}[/tex]
What is percentage?The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship between a component and a whole in which the value of the whole is always assumed to be 100.
Let, the odd price be x then
we can write the new amount as a percentage of the price before increasing as

Vec a and vec b are two unit vectors. If vec 5a + vec 3b and vec a- vec b are perpendicular to each other, find the angle between a and b.
[tex]\vec{a}[/tex] and [tex]\vec{b}[/tex] are two unit vectors. If [tex]\vec{5a} + \vec{3b}[/tex] and [tex]\vec {a} - \vec {b}[/tex] are perpendicular to each other, then the angle between a and b is ( 2n + 1)π/2.
As given in the question,
Given two unit vectors are : [tex]\vec{a}[/tex] and [tex]\vec{b}[/tex]
|a| = 1 and |b| = 1
Vectors which are perpendicular to each other are :
[tex]\vec{5a} + \vec{3b}[/tex] and [tex]\vec {a} - \vec {b}[/tex]
( [tex]\vec{5a} + \vec{3b}[/tex] ). ( [tex]\vec {a} - \vec {b}[/tex] ) = 0
⇒ 5|a|² -2a.b - 3|b|² = 0
⇒ 5(1)² - 2a.b - 3(1)² = 0
⇒ 5 - 2a.b - 3 = 0
⇒ 2[tex]\vec{a}[/tex].[tex]\vec{b}[/tex] = 2
⇒ [tex]\vec{a}.\vec{b}[/tex] = 1
Let θ be the angle between two vectors
|a||b|cosθ = 1

⇒cosθ = 1
⇒θ = (2n+1)π/2
Therefore, [tex]\vec{a}[/tex] and [tex]\vec{b}[/tex] are two unit vectors. If [tex]\vec{5a} + \vec{3b}[/tex] and [tex]\vec {a} - \vec {b}[/tex] are perpendicular to each other, then the angle between a and b is

A monkey can eat 24 pieces of fruit in 12 hours.
The equation y = 2x can be used to represent
this situation. What is the constant of
proportionality? What does the constant of
proportionality represent in the context of the
problem?
The constant of proportionality for the equation y = 2x is k = 2.
The number of pieces of fruit the monkey can eat is two times the amount of time the monkey takes.
The equation y = 2x can be used to represent a monkey eating 24 pieces of fruit in 12 hours.
The constant of proportionality, which is a fixed value that represents the rate at which two or more ratios rise or decrease, is used to compare them. The result of dividing the denominator by the numerator when a ratio is expressed as a fraction is the constant of proportionality.
When a ratio is expressed as a fraction, the constant of proportionality is found by dividing the denominator by the numerator. The constant of proportionality, k, can be calculated from the equation if x is the ratio's numerator and y is its denominator.
k = y/x
Therefore, the constant of proportionality in this case is:
y = 2x
k = y/x = 2
The constant of proportionality in this case represents that the number of pieces of fruit a monkey eats is two times the amount of time the monkey takes.

What is the value of 6a + 9b?
Step-by-step explanation:
Simplifying
6a + -9b = 0
Solving
6a + -9b = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '9b' to each side of the equation.
6a + -9b + 9b = 0 + 9b
Combine like terms: -9b + 9b = 0
6a + 0 = 0 + 9b
6a = 0 + 9b
Remove the zero:
6a = 9b
Divide each side by '6'.
a = 1.5b

what is the maximum amount of money she will earn in the craft fair?
________________________________________
1 lb of candle wax will fill 20 oz
She buys a 5-pound package, therefore, she will fill 20*5= 100 oz
Tin size S small (4 oz ) and M medium (6 oz)
S*4 + M*6 = 100
S*7.5 + M*9 = amount of money
_____________________
S*4 + M*6 = 100
4 S = 100 - 6M
S= 100/4 -6/4M
S= 25 -3/2M
Replacing
(25 -3/2M )*7.5 + M*9 = amount of money
187.5 - 11.25M + 9M = amount of money
187.5 - 2.25M = amount of money
According to the expression, the fewer medians sell, the higher the income will be.
Reviewing the candle values by ounces used.
7.5/ 4 = 1.875 sale price / oz
9.0/6 = 1.5 sale price / oz

Given the figure of an object consists of a cylinder and a rectangular prism.
We will find the volume of the cylinder using the following formula:
[tex]V=\pi r^2h[/tex]As shown, the diameter of the base = d = 3 ft
So, the radius = r = d/2 = 3/2 = 1.5 ft
And the height = h = 4 ft
Use π = 3
so, the volume of the cylinder will be as follows:
[tex]V=3*1.5^2*4=27\text{ }ft^3[/tex]Now, we will find the volume of the rectangular prism using the following formula:
[tex]V=l*w*h[/tex]As shown, the length = l = 7 ft
The width = w = 4 ft
The height = h = 4 ft
So, the volume of the rectangular prism will be as follows:

Complete the square to solve the equation below.

O A. x= 4+ √√30; x = 4 - √30
OB. x= -10 + √55; x = -10 - √55
C. x = 5 + √√29; x = 5-√√√29
OD. x= -5+ √55; x = -5- √55
Answer:
D
Step-by-step explanation:
...................
The solutions to the quadratic equation x² + 10x - 13 = 17 are x = -5 + √55 and x = -5 - √55. The correct answer is option D.
The quadratic equation is given as:
x²+10x-13 =17
Move the constant term to the right side of the equation:
x² + 10x - 13 - 17 = 0
x² + 10x - 30 = 0
Take half of the coefficient of the x-term (10) and square it: (10/2)² = 25.
Add the squared value to both sides of the equation:
x² + 10x + 25 - 30 = 25
(x + 5)² - 30 = 25
Simplify the equation:
(x + 5)² = 25 + 30
(x + 5)² = 55
Take the square root of both sides of the equation:
√((x + 5)²) = ±√55
x + 5 = ±√55
Solve for x by subtracting 5 from both sides:
x = -5 ± √55
Therefore, the solutions to the equation x² + 10x - 13 = 17 are:
x = -5 + √55 and x = -5 - √55.

The non-real solutions of the polynomial expression are x = (2 + i√26)/3 and x = (2 - i√26)/3
How to determine the non-real solutions?The equation of the polynomial expression is given as:
3x^3 + 14x^2 - 14x + 60 = 0
From the question, we have
Real solution = -6
Rewrite the above equation as
x = -6
Add 6 to both sides of the equation
So, we have
x + 6 = 0
The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0
This is represented as
3x^3 + 14x^2 - 14x + 60/x + 6
Using a graphing calculator, we have
3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10
Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula
So, we have
x = (-b ± √(b² - 4ac))/2a
This gives
x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3
So, we have
x = (4 ± √-104)/6
This gives
x = (4 ± 2√-26)/6
Divide
x = (2 ± √-26)/3
Rewrite as
x = (2 ± i√26)/3
Split
x = (2 + i√26)/3 and x = (2 - i√26)/3
So, the conclusion is that
