Answer:
There are 30 temporary employees
Step-by-step explanation:
To find x% of quantity A, multiply x% by A after change x% to the normal number by divide it by 100 ⇒ (x ÷ 100) × A
Let us use this rule to solve the question
∵ The local water slides have 100 employees
∵ 30% of them are temporary
∴ The number of temporary employees = 30% × 100
∵ 30% = 30 ÷ 100 = 0.30
∴ The number of temporary employees = 0.30 × 100
∴ The number of temporary employees = 30
∴ There are 30 temporary employees
Jelly beans cost $15.98 for a 2 kg bag. At this rate, how much would 7 kg cost
Answer:
lets see every 2kg bag its 15.98 so every 4kg its 31.96 and for every 6kg its 47.94 so if every 1kg its 7.99 so add 47.94 + 7.99 you get 55.93

⚠️⚠️What’s the equation (Y=Mx+b) and B? ⚠️⚠️
Answer:
The equation for this line in slope-intercept form (y = mx + b) is y = [tex]\frac{5}{4}[/tex]x + 2, because the rise (5) over the run (4) is the slope aka 'm', and the line touches the y-axis at the point (0,2) In this ordered pair the y-value is 2, so the y-intercept, or 'b', is equal to 2.
Solve for x in the equation x2 - 8x+41 - 0
X=-41 371
x= -4 + 5i 0 X-4+ 371
x = 4 + 5/
Answer:
x= 4+5i
Step-by-step explanation:
The values of x in the given quadratic equation, x²-8x+41 = 0 are x = 4+5i or x = 4-5i
What is quadratic equation?A quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c represent known numbers, where a ≠ 0.
Given is a quadratic equation, x²-8x+41 = 0, we need to find the values of x,
Since, 41 is a prime number, which can not be factorized so, we will use quadratic formula,
x = [-b ± √(b²-4ac)] / 2a
Here, a = 1, b = -8, c = 41
Therefore,
x = [8 ± √(8²-4(41))] / 2
= [8 ± √(64-164)] / 2
= [8 ± √(-100)] / 2
= [8 ± 10i] / 2
= [4 ± 5i]
Therefore, x = 4+5i or x = 4-5i
Hence, the values of x in the given quadratic equation, x²-8x+41 = 0 are x = 4+5i or x = 4-5i

Find the coordinates of point P along the directed line segment AB so that AP to PB is the given ratio. A(10, 8), B(18, 12); 1 to 3
Answer:
The coordinates of P are (12,9)
Step-by-step explanation:
Equations
We are given the endpoints of the segment AB: A(10,8) B(18,12).
It's required to find the coordinates of point P(x,y) along the segment AB such that:
[tex]\displaystyle \frac{AP}{PB}=\frac{1}{3}[/tex]
The ratio of the distances is the same as the ratio of their respective coordinates:
[tex]\displaystyle \frac{x_{AP}}{x_{PB}}=\frac{1}{3}[/tex]
[tex]\displaystyle \frac{y_{AP}}{y_{PB}}=\frac{1}{3}[/tex]
Since
[tex]x_{AP}=x_P-x_A=x-10[/tex]
[tex]x_{PB}=x_B-x_P=18-x[/tex]
Then:
[tex]\displaystyle \frac{x-10}{18-x}=\frac{1}{3}[/tex]
Multiplying by 3 (18-x):
3( x - 10 )= 18 - x
3x - 30 = 18 - x
Adding x and 30:
4x = 48
x = 12
Similarly:
[tex]\displaystyle \frac{y-8}{12-y}=\frac{1}{3}[/tex]
Multiplying by 3 (12-y):
3( y - 8 ) = 12 - y
3y - 24 = 12 - y
Adding y and 24:
4y = 36
y = 9
The coordinates of P are (12,9)
y+2 = -3(x – 4)
Complete the missing value in the solution to the equation.

Answer:
The missing value in the solution to
the equation will be:
[tex]x=4[/tex]Step-by-step explanation:
Given the equation
[tex]y+2\:=-3\left(x\:-\:4\right)[/tex]
As the value of y = -2 is given.
so substituting the value y = -2 in the equation to find the missing value
[tex]\left(-2\right)+2\:=-3\left(x\:-\:4\right)[/tex]
switch the sides
[tex]-3\left(x-4\right)=\left(-2\right)+2[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a[/tex]
[tex]-3\left(x-4\right)=-2+2[/tex]
[tex]-3\left(x-4\right)=0[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}-3[/tex]
[tex]\frac{-3\left(x-4\right)}{-3}=\frac{0}{-3}[/tex]
[tex]x-4=0[/tex]
[tex]x=4[/tex]
Therefore, the missing value in the solution to

Answer:
1st is 26.376 2nd is n
Step-by-step explanation:
2pie X r so. 2 X3.14X4.2
Answer:
26.376 cm
4 is the constant
Step-by-step explanation:
C = [tex]2\pi r[/tex]
To find the circumference, we first need to find the radius. The radius of a circle is half the diameter, so divide 84 by 2:
84/2 = 42
The radius is 42. Now we can solve for the circumference:
C = 2[tex]\pi[/tex](42)
C = 84[tex]\pi[/tex]
C = 263.89
The circumference is approximately 263.89 mm. Now we need to convert the millimeters to centimeters. There are 10 millimeters in 1 centimeter, so divide the circumference by 10:
263.89/10 = 26.389
The circumference is approximately 26.389 cm. The answer choice that our answer is closest to is the first answer choice.
4 + 2n
The constant in an expression is the value that doesn't change. After 2 and n are multiplied, that value will be different, so their values aren't constant. So, in this expression, 2 is the coefficient, n is the variable, and 4 is the constant.

Find the ordered triple of these equations.
X + y + z = 12
y = 1
X - Y - Z = 0
Answer:
the ordered triple of these equations will be:
(x, y, z) = (6, 1, 5)
Step-by-step explanation:
Given the equations
[tex]x + y + z = 12[/tex]
[tex]y=1[/tex]
[tex]x - y - z = 0[/tex]
As
[tex]y=1[/tex]
We can get the value of x by adding the first and third equation
so
[tex]x + y + z = 12[/tex]
[tex]x-y-z=0[/tex]
so the equations become
[tex]x+x+y-y+z-z=12+0[/tex]
[tex]2x = 12[/tex]
[tex]x = 6[/tex]
Putting x = 6 and y=1 in the first equation [tex]x+y+z=12[/tex]
[tex]6 + 1+ z = 12[/tex]
[tex]7 + z = 12\\z = 12 -7[/tex]
[tex]z = 5[/tex]
Therefore, the ordered triple of these equations will be:
(x, y, z) = (6, 1, 5)

Based on the Egyptian Social Pyramid, which statement below is true?
Scribes protected the kingdom from invasion.
Merchants made up a large portion of the pharaoh's police force.
If a boy didn't want the same job as his father, he could go to scribe school.
Farmers, servants, and slaves made up 20% of the population.
Answer:
Third Option
Step-by-step explanation:
Lets use process of elimination to find the answer to this question. It's not the first option because a scribes job was mainly in the government district as writers/record keepers meaning they don't really protect the kingdom from invasion. It's not the second options because Merchants were traders, meaning they don't make up the Pharaohs police force because all they do is sell goods to Egyptians. Then it's not fourth option because farmers, servants, and slaves make up way more then 20% of ancient Egypt. Leaving the third option meaning it's your answer.

What is the measure of <C ? O 38° O 76° O 90° O 152°
Answer:
Your answer is 38 degrees.
Step-by-step explanation:
The question was solved through the properties of a circle. The angle subtended at the center is double the angle subtended at the circumference.
Hope I helped, happy schooling!!
The measure of <C is 38°. The answer is the first option 38°
Circle theoremsFrom the question, we are to determine the measure of <C.
In the diagram, <C is an angle on a part of the circumference.
From the given information, the angle subtended by arc AB at the center of the circle is 76°
From one of the circle theorems we have that
The angle subtended by an arc of a circle at its center is twice the angle it subtends anywhere on the circle's circumference
Therefore,
2 × <C = 78°
<C = 76° ÷ 2
<C = 38°
Hence, the measure of <C is 38°. The answer is the first option 38°

The graph shows the height of a plant over a 2-month growth period. Calculate the rate of change per day.
Answer:
14/61 cm per day
Step-by-step explanation:
Use the slope formula [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Plug it in [tex]\frac{16-2}{61-0}[/tex]
Simplify [tex]\frac{14}{61}[/tex]
If the graph shows the height of a plant over a 2-month growth period. The rate of change per day will be 14/61.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables. Analyze the points first, then calculate the y-values for each interval. After that, subtract the input and output values. Divide and then simplify the differences to determine the rate of change.
It is given that, the graph shows the height of a plant over a 2-month growth period
The kind of graph must be considered when calculating the rate of change. Finding the ratio between the change in output values and the change in their corresponding input values is how linear graphs with constant rates of change are determined. Look at the following linear graph.
The slope of a linear function represents the pace of change. We have two points to determine the slope,
The rate of change per day is found as,
=y₂-y₁/x₂-x₁
=16-2/61-0
=14/61
Thus, if the graph shows the height of a plant over a 2-month growth period. The rate of change per day will be 14/61.

What are the slope and the y-intercept of the graph of the linear function shown on the grid?
(-6, 0) (2,-2)
Answer:
hi! the slope formula is y2-y1 / x2-x1 ! so (-6,0) (2,-2)
your x1 is -6 and y1 is 0 and x2 is 2 and y2 is -2!
using the formula, -2-0/2--6 is 4
so your slope is 4!
the y intercept is solved by
the slope intercept formula y= mx+b
I hope you've memorized both formulas!
b is your y intercept so let's set the equation up!
pick a point it can be either point we'll do (-6,0)!
now y=mx + b
m is your slope and y is the y coordinate of the point (-6,0) that we chose!
b is what we will solve
so! 0=4(-6)+b
0= -24 + b
now it's basic algebra!
24= b
I hope this helps!
In conclusion, slope is 4 and y intercept is 24
memorize slope formula and slope intercept formula and you can do this!
