Using the percentage and hours, the total number of technician that was there is 42.
How to find the number of technicians that are there?The project is budgeted for 2400 hours and will last 3 weeks.
This means the whole project will last for 2400 hours for 3 weeks.
Technicians will cover 25% of the project for the first week and then 60% for the final two weeks.
This simply implies 25% of the project will be completed in the first week. Then 60% of the remainder of the project will be completed the final two weeks.
Each technician normally works 40 hours per week.
Therefore,
Number of hours for the first week = 25 % of 2400
Number of hours for the first week = 25 / 100 × 2400
Number of hours for the first week = 600 hours
Therefore,
number of technicians for the first week = 600 / 40
number of technicians for the first week = 15 technicians
Therefore,
Number of hours for the final two week = 60 % of (2400 - 600)
Number of hours for the final two week = 60 / 100 × 1800
Number of hours for the final two week = 1080 hours
Hence,
number of technicians for the final two week = 1080 / 40
number of technicians for the final two week = 27 technicians
Therefore, the total number of technician that was there is 42.

The sum of four and eight times a number is -76.
Answer: x = -10
▬▬▬▬▬▬▬▬▬▬
Given problem,[tex]4 + 8 \times x = -76[/tex]
Find x▬▬▬▬▬▬▬▬▬▬
[tex]4+8(x)-4=-76-4\\8(x)=-80\\\frac{8(x)}{8}=\frac{-80}{8}\\= -10\\x = -10[/tex]

Answer Explained:
Given the keywords sum(add), times(multiply), as well as a number(variable), we can make an equation out of this, which was 4 + 8 * x = -76. We subtracted the sides by 4, then divided both of the sides by the next factor, 8, to get -10.
Thus,
4 + 8 × -10 = -76

Ling is a camp counselor at a local summer camp. She is in charge of the weekly craft activity
for 40 campers. She plans to make fabric-covered frames that each require 1/6 yard of fabric.
The camp director gave her 6 2/3 yards of fabric remnants for this project. Does Ling have
enough fabric for her craft activity?
She has the exact amount of fabric that she needs for this project.
Does Ling have enough fabric for her craft activity?
We know that she is in charge of 40 campers, and she wants to make fabric-covered frames, such that each one needs 1/6 yards of fabric.
We know that he has a total of 6 + 2/3 yards to do this, and we need to see if that is enough.
Now, for each one of the 40 campers she needs 1/6 yards, so the total amount she needs is given by the product:
T = 40*(1/6 yards) = 40/6 yards = (36 + 4)/6 yards = (6 + 4/6) yards
T = (6 + 2/3) yards
So she has the exact amount of fabric that she needs for this project.

Drake Kennedy's regular-time pay rate is $12.73 an hour. Last week he was paid for 37.5 hours at his
regular rate and for 5 hours at a time-and-a-half overtime rate. Find Drake's gross pay for week?
Answer:First, determine the total number of hours worked by multiplying the hours per week by the number of weeks in a year (52). Next, divide this number from the annual salary.if an employee has a salary of $50,000 and works 40 hours per week, the hourly rate is $50,000/2,080 (40 x 52) = $24.04.
Step-by-step explanation:
Divide the gross pay by the wage hours worked. For example, if your records show that the employee was paid $4,000 for the total month, divide 4,000 by 172 to reach $23.26. This is an accurate representation of an hourly rate for that employee's monthly work.
for the function f(x) = 4x+2, evaluate and simplify the difference quotient
The difference quotient of the function f(x) = 4x + 2 is 4.
What is a function?Functions were originally the idealization of how a varying quantity depends on another quantity.
The given function is,
f(x) = 4x + 2
For a given function f(x), we define the difference quotient as:
[tex]\frac{f(x+ h)-f(x)}{h}[/tex]
Thus, for the given function, difference quotient is given as,
[tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4(x+h)+2-(4x+2)}{h}[/tex]
expanding the brackets we get,
[tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4x+4h+2-4x-2}{h}[/tex]
Solving we get,
⇒ [tex]\frac{f(x+ h)-f(x)}{h}[/tex] = [tex]\frac{4h}{h}[/tex]
Thus,we get

What are the coordinates of G after it is ROTATED 90 DEGREES CLOCKWISE?
The coordinates of G after it is rotated by 90 degrees will be ( 3, 4 ).
What is a translation?
The process of changing the location of the image on the coordinate system will be known as the translation.
Our point A(x,y) becomes A' when a point is rotated 90 degrees counterclockwise about the origin (-y,x). To put it another way, flip x and y, and make y-negative.
Given that point, G is translated to 90 degrees. The translated coordinates of point G will be calculated as:-
( -x, y ) = ( y, x )
( -4 , 3 ) = ( 3 , 4)
Therefore, the coordinates of G after it is rotated by 90 degrees will be ( 3, 4 ).

In the expression 5 + 2 + 5x + 2x + x we can combine the like terms to get the simplified form of the expression as 7 +8x.
What are like terms?If two words have the same variable portion, we refer to them as "like terms." When comparing algebraic terms to locate similar terms, we first disregard the coefficients and merely check to see if the variables and exponents are the same. The terms that meet this requirement are known as like terms.
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

What is defined as the linear equation in two variables?A linear equation in two variables is one that is written in the form ax + by + c = 0, where a, b, and c are real numbers and also the coefficients of x and y, i.e. a and b, are not equal to zero.
If there is only one solution, the given lines are intersecting; if no solution is possible, the given equations have been of parallel lines. If there are an infinite number of solutions, it means that given equations form coincident lines.For the given question.
Let 'x' be the number of matinee showings.
Let 'y' be the number of prime-time showings.
Then. the total ticket sold are 1,411.
Thus, x + y = 1,411.
or, x = 1,411 - y
The cost of one matinee showings is $9.
The cost of one prime-time showings is $13.50.
Now, the total cost earned is $17,149.50.
So,
9x + 13.5y = 17,149.50
Put the value of the 'x' in the above equation.
9(1,411 - y) + 13.5y = 17,149.50
Simplifying;
12699 - 9y + 13.5y = 17,149.50
4.5y = 4450.5
y = 989.
Calculate x;
x = 1,411 - 989
x = 422
Therefore, the number of matinee and prime-time movie tickets were sold that day are 422 and 989.

f(-2) = 4 + 6 + 5

In general, f(x) can be thought of as being y. So the equation could read as "Let x = - 2" when y = x^2 - 3x + 5.
Another way of thinking of it is by saying f(-2), wherever you see an x on the right hand side, substitute the value given on the left side (in this case x = - 2
