The electricity contract with the utility company is structured so that higher daily energy usage is charged at a lower rate.
The plant’s production processes are performed primarily by robots that are able to work longer hours, when needed, at no additional cost.
Overtime wages were required to produce at levels above 25,000 units.
What is the cost?
A cost is an expenditure required to produce or sell a product or get an asset ready for normal use.
The cost of production per unit of the item produced is 1$ as long as the total units produced are less than 2500.
If more than 2500 units are produced then the cost per unit actually comes down to 0.8$per unit.

What is the mean in a math problem
Answer:
the mean is the average of a set of numbers
Step-by-step explanation:
for example, if a set of numbers were 1,2, and 3, the mean would be 2 because the average is 2.
This can be calculated by adding 1, 2, and 3, and dividing them among all three numbers

Answer:
generally, the sum divided by the number of summands
Step-by-step explanation:
In math the term "mean" can have different meanings, depending on the context. It will generally refer to the arithmetic mean, if no additional qualifiers are given. The arithmetic mean is also called the average.
__
arithmetic meanThe arithmetic mean of a set of numbers is their sum, divided by the number of numbers. It is sometimes represented by the Greek letter μ or a variable with an overbar.
[tex]\overline{x}=\dfrac{x_1+x_2+\dots +x_n}{n}[/tex]
geometric meanThe geometric mean will be the n-th root of the product of n numbers.
[tex]\text{geometric mean}=\sqrt[n]{x_1\cdot x_2\dots\cdot x_n}[/tex]
harmonic meanThe harmonic mean is the reciprocal of the arithmetic mean of the reciprocals.
[tex]\text{harmonic mean}=\dfrac{n}{\dfrac{1}{x_1}+\dfrac{1}{x_2}+\dots+\dfrac{1}{x_n}}[/tex]
proportionIn a proportion written as ...
a/b = c/d
The two values closest to the middle of the expression (b and c) are called the "means". Those farthest away (a and d) are called the "extremes". It is said that ...
the product of the means is equal to the product of the extremes
Which combined inequality has the same solution set shown in the graph?
Number line ranging from negative sixteen to zero with a line beginning with a close point at negative twelve and continuing to the left without end, and a second line beginning with a closed point at negative five and continuing to the right without end.
a ≤ –12 or a > 5
a ≤ –12 or a > –5
–a ≤ –12 or a > –5
–a ≤ –12 or a < –5
Step-by-step explanation:
there is a problem here. based on your textual description none of the 4 answer possibilities are right.
you said, one line starts with a closed (filled) point at -12 and going to the left (without end). a closed point means the point is included.
so, everything -12 and smaller.
that is a <= -12
the other line starts with a closed (filled) point at -5 and goes to the right without end.
this is a >= -5
so, if your textual description is right, you need an answer option
a <= -12 or a >= -5
FYI
the answer options with -a <= -12 don't make much sense, because that simply means a >= 12. and you don't have any line starting at plus 12 and going to the right.

Child labor is a service rendered by children in any field during their childhood. This is done due to lack of resources for subsistence, irresponsibility of the parents or lack of resources by the owner to increase their returns on low investment.
This does not matter with the cause of child labor as all the reasons force children to live life without childhood. Childhood is the greatest and happiest period of everyone’s life, during which one learns about the basic strategy of life from parents, loved ones and nature. Child labor interferes with the proper growth and development of children in all aspects, mentally, physically, socially and intellectually.

The moon forms a right triangle with the Earth and the Sun during one of its phases, as shown below.
A scientist measures the angle x and the distance y between the Earth and the Sun. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the moon and
the Sun.
Answer:
by using pythagoras theorem
Step-by-step explanation:
the distance between sun and moon is hypoteneous
the distance between earth and sun is perpndicular
and distance between earth and moon is base
we can use,
tanx°=distance betwwen earth and sun/ distance betweenearth and moon
or,
sinx°= distance between earth and sun/ distance between sun and moon
we can use other formulas also same as above 2 examples
Hope ithelps
Answer:
The scientist can use trigonometry to figure out the distance between the Moon and Sun. More specifically, using sine (sin).
Step-by-step explanation:
Label the triangle first.
- x should be theta
- y would be opposite (o) as it is across/opposite from the side where x is
- the distance between the sun and moon would be hypotenuse (h), as it's opposite of the right angle.
The calculation that has o and h in it's formula is sine. The formula looks like :
Sin(Ф) = [tex]\frac{o}{h}[/tex]
To solve for the distance between the Sun and Moon, we plug it into the formula and solve
Sin(x) = [tex]\frac{d}{y}[/tex]
- where d is the distance between the Sun and Moon

Anne, Bridget, and Sasha shared a sum of money. Anne took 1/3 of the total amount, and Bridget took 1/4 of the remaining money. After both of them had taken their share, Sasha took 1/2 of what was left. If Anne took $160, how much did Sasha take?
Answer:
180
Step-by-step explanation:
160= 1/3 * total
160*3 = total
480 = total
bridget = 1/4(total)
bridget = 1/4(480)
bridget took 120
Sasha took 1/2 of 360
Sasha took $180.
Salazar assigns the same number of homework questions each school day. The ratio table below shows the total number of homework questions assigned after a certain number of school days.
After 16 days, how many total homework questions have been assigned?
A:60
B:80
C:95
D:115
Answer:
B
Step-by-step explanation:
First, we have to find the rate of change for this problem. To do this, we subtract any two numbers of days and the coordinating two total questions. Let's just use the first two rows. 8-4=4, and 40-20=20. For every 4 days, he answers 20 questions. We can further simplify this by dividing both sides by 4. 4/4=1, and 20/4=5. For every 1 day, he answers 5 questions. Now, to find 16 days, we just multiply both sides by 16. 16*1=16 and 16*5=80. For every 16 days, he answers 80 questions. 80 is our answer.

22. Which is an expression for the area
of ABC?
Answer:
C
Step-by-step explanation:
the area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] product of 2 sides × sin ( angle between the 2 sides )
We are only given 1 side (AC) so require to find AB or BC using the Sine rule
the third angle B = 180° - (48 + 67)° = 180° - 115° = 65°
using the Sine rule to find AB
[tex]\frac{AB}{sin67}[/tex] = [tex]\frac{15}{sin65}[/tex] ( cross- multiply )
AB × sin65° = 15 × sin67° ( divide both sides by sin65° )
AB = [tex]\frac{15sin67}{sin65}[/tex]
Now
A = [tex]\frac{1}{2}[/tex] × AB × AC sin48°
= [tex]\frac{1}{2}[/tex] × [tex]\frac{15sin67}{sin65}[/tex] × 15sin48°
= [tex]\frac{15sin67}{2sin65}[/tex] × 15sin48° → C

The exact height of the triangle is 20.8ft
The area of the right tringle in radical form is 72√3 ft²
The area of the triangle in decimal form is 124.7 ft²
How to find the side and area of a right angle triangle?The side XY or height of the triangle can be found as follows:
Using trigonometric ratios,
tan 60° = XY / 12
XY = 12 tan 60°
XY = 12 × 1.73205080757
XY = 20.7846096908
height = 20.8ft
The area of XYZ = 1 / 2 bh
where
b = baseh = heightTherefore,
The area of XYZ = 1 / 2 × 12 × 20.8 = 124.707658145 = 124.7 ft²
The area in radical form = 1 / 2 × 12 × 12 tan 60°
The area in radical form = 1 / 2 × 12 × 12 × √3 = 144√3 / 2 = 72√3 ft²
