Step-by-step explanation:
the manufacturing costs are defined by
m(x) = 25x + 150
the selling revenue is defined by
s(x) = 50 + 30x = 30x + 50
clearly, the selling amount is bigger than the manufacturing amount (also supported by the fact that 30x > 25x). otherwise the company is going bankrupt in no time.
so,
a)
the profit is (as usual) revenue minus manufacturing :
p(x) = 30x + 50 - 25x - 150 = 5x - 100
b)
x = 150
p(150) = 5×150 - 100 = 750 - 100 = $650
since the result is positive, yes, they are making a profit. and it is $650.
Answer:
5.a) p = 5x - 100
b)p = $650
Step-by-step explanation:
5.a)
Revenue minus cost:p - Profit
p - Profitc - Cost
p - Profitc - Cost - revenue
p = r - c
p = (30x + 50) - (25x + 150)
p = 5x - 100
b) The company will make profit.
p = 5x - 100
p = 5(150) - 100
p = 750 - 100
p = $650
or
p = (30×150 + 50) - (25 × 150 + 150)
p = $650

a farmer is able to harvest 300 kg of potatoes in 5 hrs.how many kilos will 3 farmers harvest in 10hrs?
Answer:
1800 kgStep-by-step explanation:
1 farmer is able to harvest 300 kg of potatoes in 5 hrs
Then
1 farmer is able to harvest (300×2 = 600) kg of potatoes in 10 hrs
therefore,
3 farmers are able to harvest (600×3 = 1800)kg of potatoes in 10 hrs

What are some key features of sequence and series graphs?
Answer:
The key features that are unique to the graphs of sequences and series are that they are discrete.
Explanation:
That means that the graph is not a continuous line or curve that joins all the points. On the contrary, the graph is a set of separated dots, because the values are valid only for specific points.
4. The chart above shows the results of survey taken by a movie theater. The theater asked what genre the mover goers preferred to see. If the theater owner asked 100 people, how many people would prefer Drama? Round to the nearest whole number. Show your work.
The Cost of operating the theater if there are 100 people at a show is 20,000Rs.
The theater is a place where the movies are shown on big screens and Speakers are used for the clear audio of the movie.
In a theater, there will be 3 to 4 shows for a movie or a different movie.
Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.
What is the meaning of cost?The average cost of a college education has gone up dramatically.
Consider a ticket cost of 200rs.
For 100 people in a show,
Cost = 200 × 100
Cost = 20,000.
Hence the cost of operating a theater if there are 100 people at a show is 20,000Rs.

How do I solve this with a fraction?
Answer:
75°
Step-by-step explanation:
x° and (x/5)° are complementary angles.-> x° + (x/5)° = 90°-> (6x/5)° = 90°-> x° = 90° * 5/6-> x° = 75°Answer:
x = 90
Step-by-step explanation:
[tex]m\angle 1+m\angle 2=90[/tex]
[tex]\Longleftrightarrow x+\frac{x}{5} =90[/tex]
[tex]\Longleftrightarrow \frac{6x}{5} =90[/tex]

You just drove your car 450 miles and used 50 gallons of gas. You know that the gas tank on your car holds 16 1/2 gallons of gas.
What is the most number of miles you can drive on one tank of gas?
Answer: 148.5 miles
Step-by-step explanation:
450/50 gals= 9 miles can be driven for every 1 gallon.
Since we now know that our car uses 1 gallon of gas for every 9 miles we drive, we can now multiply the 9 miles with the 16 1/2= 16.5. So 16.5x9=148.5.
With our 16 1/2 gas tank, we can travel at least 148.5 miles before running out of gas.

Draw the graph of the equation 2x - y = 10.
Answer:
see attached
Step-by-step explanation:
The graph of a linear equation can be drawn using any of several methods. Here, we are given the equation in standard form. We notice that the variable coefficients are both divisors of the constant, which means the x- and y-intercepts will be integer values. It will be convenient to draw the graph using those points.
__
The x-intercept is the x-value when y = 0.
2x -0 = 10
x = 10/2 = 5 . . . . . . (5, 0) is a point on the line
__
The y-intercept is the y-value when x = 0.
0 -y = 10
y = -10 . . . . . . . (0, -10) is a point on the line
__
The graph can be drawn by plotting these points and drawing the line through them. This is shown in the attachment.

I need to find the missing angle, the letter represents the missing angle.
Answer:
88°
Step-by-step explanation:
The triangle is an isosceles triangle, so two of the angles are both 46°. We also know that the sum of all the angles in any triangle is 180°, so we can set up the following equation:
46° + 46° + e = 180°
Solving this gets e = 88°.
A print shop borrows $6700 from a credit union for 338 days the credit union charges simple interest at an annual rate of 10% for this loan assum each day is 1/365 of a year
Answer:
The total he would have to pay back would be $7,320.44
Step-by-step explanation:
(I'm assuming you want the total amount he needs to pay back)
6700 x 0.10 = 670 per year
670 ÷ 365 = 1.835616438356164
1.835616438356164 × 338 = 620.44
620.44 + 6700 = 7,320.44

Erica is playing Target One Fractions. She has these cards: 1,2,3,4,6.
a. Which three cards should she choose to make a whole number and a fraction that have a product close to 1?
b. Write an expression for the problem Erica will solve.
c. Solve the problem.
d. What is Erica's score for this round?
Answer:
a. 2, 3, 6
b. a/b × c = 1
c. a = 2, b = 6, c = 3 or a = 3, b = 6, c = 2
Step-by-step explanation:
Apparently, Erica wants to multiply a fraction by a whole number to get a result of 1. That means the fraction is the multiplicative inverse of the whole number.
__
a.There is only one set of three unique numbers among those given such that one of them is a composite number with the other two as factors. Erica must choose 2, 3, and 6.
__
b.If the three numbers are represented by a, b, c, Erica wants ...
a/b × c = 1
__
c.Multiplying the equation by b gives ...
ac = b
Among the numbers 1–6, only 2×3 = 6 will satisfy this equation. Erica can choose either of ...
a = 2, b = 6, c = 3 ⇒ (2/6)×3 = 1
a = 3, b = 6, c = 2 ⇒ (3/6)×2 = 1
__
d.No scoring information is provided.
You flip a coin and then roll a 6-sided number cube (a die).
a. When finding the probability, does it matter whether you roll the die or flip the coin first?
b. Is there more than one way to draw a tree diagram for this problem? If so, does that change the likelihood that any outcome will occur?
c. Draw the shape of the tree diagram that you would use.
d. How many outcomes are there? List them.
e. Find the probability of rolling an even number and getting heads.
Answer:
a) No, it does not matter whether you roll the die or flip the coin first, as these two events are independent of each other, which means they do not affect each other.
b) Yes.
Let event 1 be flipping a coin and event 2 be rolling a die.Let event 1 be rolling a die and event 2 be flipping a coin.The likelihood that any outcome will occur will not change, as the events are independent.
c) see attached
d) 12 outcomes (H = head, T = tail, numbers represent the value of the die)
H 1 T 1
H 2 T 2
H 3 T 3
H 4 T 4
H 5 T 5
H 6 T 6
e)
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
[tex]\implies \sf P(even)=\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{6}=\dfrac{3}{6}=\dfrac{1}{2}[/tex]

Mrs. Jones decided to buy some pencils for her class. She bought 5 packages of pencils, and each package contained 57 pencils.
There are 19 students in her class and she divided up the pencils so that each student had the same amount of pencils. If there
were no pencils left over, how many pencils did each student get?
A. 24
B. 95
C. 3
D. 15
Answer:
15 pencils
Step-by-step explanation:
5 pencils * 57 pencils is 285 total pencils
285 / 19 = 15
alternatively you can do 57/19 * 5, which is also 15

x = [ ? ],
Answer:
[tex]x = - 4[/tex]
Step-by-step explanation:
[tex]4x - 2 = - 3 \times 2 + 3x[/tex]
Calculate the product:
[tex]4x - 2 = - 6 + 3x[/tex]
Rearrange the terms:
[tex]4x - 3x = - 6 + 2[/tex]
Combine like terms:
[tex]x = - 6 + 2[/tex]
Calculate:
[tex]x = - 4[/tex]
Answer:
x = 1/2
Step-by-step explanation:
Combine exponents
4x-x-2=-3^2+3xx
4x-x-2=-3x^2+3x^2
Combine like terms
4x-2=-3x^2+3x^2
4x-2=0
Add 2 to both sides
4x-2=0
4x-2+2=0+2
Simplify:
Add the numbers
4x-2+2=0+2
4x=0+2
Add the numbers again
4x=0+2
4x=2
Divide both sides by the same factor
4x=2
4x/4 = 2/4
Simplify:
Cancel terms that are in both the numerator and denominator
4x/4 = 2/4
X= 2/4
Divid the numbers
X= 2/4
X= 1/2
Solution/ Answer
x= 1/2
