The Sugar Sweet Company needs to transport sugar to market. The graph below shows the transporting cost (in dollars) versus the weight of the sugar being
transported (in tons).
Use the graph to answer the questions.
Cost (S)
Weight (tons)
(a) How much does the cost increase for each ton of
sugar being transported?
$0
(b) What is the slope of the line?
0
X
Answers
The cost increases by $10 for each ton of sugar being transported. This can be seen from the fact that for every 1 ton increase in weight, the cost increases by $10. And the slope of the line is $10/ton.
(a) To calculate the cost increase per ton of sugar being transported, we need to find the change in cost when the weight of sugar increases by 1 ton.
Looking at the graph, we can see that the cost increases from $20 to $30 as the weight of sugar increases from 1 ton to 2 tons. Therefore, the cost increase per ton of sugar is:
$30 - $20 = $10
So the cost increases by $10 for each ton of sugar being transported.
(b) The slope of the line can be calculated using the formula:
slope = (change in y) / (change in x)
where y is the cost and x is the weight of sugar being transported.
Since the line is perfectly horizontal, the change in y is zero for any change in x. Therefore, the slope is:
slope = 0 / (change in x) = 0
So the slope of the line is zero, which means that the cost does not change as the weight of sugar being transported changes.

The sides of a triangle are x cm, (x − 4) cm and (x - 8) cm, respectively. If the cosine of the largest angle is, calculate the angles of the triangle.
Answers
the angles of the triangle are approximately 38.24 degrees, 67.53 degrees, and 74.23 degrees.
Step-by-step explanation:
Let's use the Law of Cosines to solve this problem. According to this law, in any triangle with sides of lengths a, b, and c, and angles opposite those sides denoted by A, B, and C, respectively, the following equation holds:
c^2 = a^2 + b^2 - 2ab*cos(C)
We can use this equation to find the cosine of the largest angle, which will allow us to determine the angles of the triangle.
In this case, the largest angle is opposite the longest side, which has a length of (x - 8) cm. So, let's rewrite the Law of Cosines equation in terms of x:
(x - 8)^2 = x^2 + (x - 4)^2 - 2x(x - 4)*cos(C)
Expanding and simplifying this equation gives:
x^2 - 16x + 64 = 2x^2 - 16x + 16 + 2x(x - 4)*cos(C)
Canceling out the common terms and rearranging, we get:
cos(C) = (x^2 + (x - 4)^2 - (x - 8)^2)/(2x(x - 4))
Simplifying the numerator and denominator gives:
cos(C) = (5x - 24)/(2x(x - 4))
Now, we can use a calculator to evaluate the cosine for different values of x and find the values that satisfy the given condition. Specifically, we want the cosine to be negative, since the largest angle of a triangle is always obtuse (greater than 90 degrees).
For example, if we try x = 10, we get:
cos(C) = (5(10) - 24)/(2(10)(6)) = -0.25
This satisfies the condition, so we can use this value of x to find the angles of the triangle:
Angle opposite x cm side = cos^-1((x^2 + (x - 4)^2 - (x - 8)^2)/(2x(x - 4)))
= cos^-1((10^2 + (10 - 4)^2 - (10 - 8)^2)/(210(10 - 4)))
= cos^-1(7/8)
≈ 38.24 degrees
Angle opposite (x - 4) cm side = cos^-1((x^2 + (x - 8)^2 - (x - 4)^2)/(2x(x - 8)))
= cos^-1((10^2 + (10 - 8)^2 - (10 - 4)^2)/(210(10 - 8)))
= cos^-1(3/8)
≈ 67.53 degrees
Angle opposite (x - 8) cm side = 180 - angle opposite x cm side - angle opposite (x - 4) cm side
= 180 - 38.24 - 67.53
≈ 74.23 degrees
Therefore, the angles of the triangle are approximately 38.24 degrees, 67.53 degrees, an the angles of the triangle are approximately 38.24 degrees, 67.53 degrees, and 74.23 degrees.

1. What is the breakeven point in unit sales and dollars for each type of filter at the current sales mix?
Answers
For fau/cet filter:
The break-even point in unit sales is 28,571 units.The break-even point in dollar is $2,571,390.For pitcher-filter:
The break-even point in unit sales is 22,222 units.The break-even point in dollar is $2,444,420.How do we calculate breakeven point in unit sales and dollars?Let's start with the fau/cet model:
Contribution margin per unit = selling price - variable cost
Contribution margin per unit = $90 - $25
Contribution margin per unit = $65
Contribution margin ratio = contribution margin per unit / selling price
Contribution margin ratio = $65 / $90
Contribution margin ratio = 0.722
The sales mix is 2 faucet models for every 3 pitcher filters sold, so the contribution margin weighted average is:
= (2/5)($65) + (3/5)($90-$20)
= $42
Now we can calculate the break-even point in units for the faucet model:
= Total fixed costs / contribution margin per unit
= $1,200,000 / $42
= 28,571 units
For pitcher filter:
Contribution margin per unit = selling price - variable cost
Contribution margin per unit = $110 - $20
Contribution margin per unit = $90
Contribution margin ratio = contribution margin per unit / selling price
= $90 / $110
Contribution margin ratio = 0.818
Contribution margin weighted average:
= (2/5)($25) + (3/5)($90-$20)
= $54
Break-even point in units for pitc/her filter:
= Total fixed costs / contribution margin per unit
= $1,200,000 / $54
= 22,222 units
Break-even point in dollars for fau/cet model:
= 28,571 units x $90 per unit
= $2,571,390
Break-even point in dollars for pitc/her-filter:
= 22,222 units x $110 per unit
= $2,444,420

[tex]z-score for 3.6 ounces = (3.6 - 3.5) / 0.16 = 0.625[/tex]
Using a z-table or a calculator with a normal distribution function, we can find that the percentage of candy wrappers between these two values is approximately 47.70%.
b. To find the percentage of candy wrappers that would have less than 3.3 ounces, we need to calculate the z-score for this value:
[tex]z-score for 3.3 ounces = (3.3 - 3.5) / 0.16 = -1.25[/tex]
Using a z-table or a calculator with a normal distribution function, we can find that the percentage of candy wrappers with less than 3.3 ounces is approximately 10.92%.
To find the percentage of candy wrappers with more than 3.62 ounces, we need to calculate the z-score for this value:
[tex]z-score for 3.62 ounces = (3.62 - 3.5) / 0.16 = 0.75[/tex]
Using a z-table or a calculator with a normal distribution function, we can find that the percentage of candy wrappers with more than 3.62 ounces is approximately 22.77%.
c. To find how many of the 1358 packets made that day have between 3.35 and 3.65 ounces, we need to convert these values to z-scores:
[tex]z-score for 3.35 ounces = (3.35 - 3.5) / 0.16 = -0.9375[/tex]
[tex]z-score for 3.65 ounces = (3.65 - 3.5) / 0.16 = 0.9375[/tex]
Using a z-table or a calculator with a normal distribution function, we can find the percentage of candy wrappers between these two values, which is approximately 62.97%. To find how many packets this represents, we can multiply this percentage by the total number of packets made:
[tex]0.6297 * 1358 = 856 packets[/tex]
Therefore, approximately 856 packets made that day have between 3.35 and 3.65 ounces.
d. To find how many games Tim would have scored 22 points or more if he plays 32 games, we first need to calculate the z-score for this value:
[tex]z-score for 22 points = (22 - 20.2) / 25 = 0.072[/tex]
Using a z-table or a calculator with a normal distribution function, we can find the percentage of games with a z-score greater than or equal to 0.072, which is approximately 53.10%. To find how many games this represents, we can multiply this percentage by the total number of games:

The salaries did not rise with inflation. The butter is now 25% costlier. By what percentage should a housewife reduce the consumption, so that her expenditure stays the same
Answers
The percentage of reduction in consumption required to keep the same expenditure is 25%.
What is Inflation?Inflation is an economic phenomenon that occurs when the prices of goods and services increase over time.
To find out the percentage of reduction in consumption, we need to calculate the difference between the current and the original prices of the butter.
This can be done by subtracting the original price of the butter from the current price of the butter (25% costlier).
The difference can be expressed as a percentage by dividing the difference by the original price.
Therefore, the percentage of reduction in consumption required to keep the same expenditure is 25%.
This means that a housewife needs to reduce her consumption of butter by 25% in order to keep her expenditure the same.

Combine like terms
4x + 360 = 540
Subtract 360 from both sides to isolate x
4x + 360 - 360 = 540 - 360

The volume of a cuboid is 108cm3.
The length is 4cm and the width is 9cm.
Work out the height of the cuboid.
Answers
Answer:
You can use the formula for the volume of a cuboid, which is Volume = length x width x height
You are given the volume of the cuboid as 108cm^3, the length as 4cm, and the width as 9cm. Let's substitute these values into the formula and solve for the height:
108cm^3 = 4cm x 9cm x height
To solve for height, you can divide both sides by 36 (which is equal to 4cm x 9cm) to isolate height:
108cm^3 ÷ 36 = 4cm x 9cm x height ÷ 36
3cm = height
So the height of the cuboid is 3cm.

SOLVE LAW OF INDICES
Answers
Answer:
To solve this problem, we can use the laws of indices, specifically the law that states that (a^m)^n = a^(m*n).
So, we have:
(1/64)^(2/3) = (1^(2/3))/(64^(2/3))
Since any number raised to the power of 1 is itself, we can simplify the numerator to just 1.
Now, we have:
(1/64)^(2/3) = 1/(64^(2/3))
To evaluate 64^(2/3), we can use the law of indices again, which states that a^(1/n) = nth root of a. In this case, we have:
64^(2/3) = (64^(1/3))^2 = 4^2 = 16
So, substituting this back into the original expression, we have:
(1/64)^(2/3) = 1/16
Therefore, (1/64)^(2/3) simplifies to 1/16.
Step-by-step explanation:
Answer:
Using the law of indices, we have:
(1/64)^(2/3) = (1^(2/3))/(64^(2/3))
Now we need to simplify the denominator by finding the cube root of 64:
64^(1/3) = 4
Substituting this value in the original expression, we get:
(1/64)^(2/3) = (1^(2/3))/(4^2)
Simplifying further, we have:
(1/64)^(2/3) = 1/16

If x is 9 or any number greater than 9 the side length will be greater than 14 so x must be below nine so when the extra 5 is added it is still less than 14.

The length of the arc that is drawn in a circle of radius 14 cm and angle of arc 135° is approximately 32.67 cm.
What is an arc?An arc is a portion of a curve that is part of a circle. It is defined as a continuous portion of the circumference of a circle. In other words, an arc is a segment of a circle's circumference.
To find the length of an arc of circle, you can use the formula:
arc length = (angle of arc / 360) x (2 x π x radius)
Where π (pi) is a mathematical constant approximately equal to 3.14.
In this problem, the radius of the circle is given as 14 cm and the angle of the arc is 135°. So, By substituting these values in the formula, we get:
arc length = (135/360) x (2 x π x 14)
arc length = (3/8) x (2 x 3.14 x 14)
arc length = (3/8) x (87.92)
arc length = 32.67 cm (rounded to two decimal places)

For the cost and price functions below, find a) the number, q, of units that produces maximum profit; b) the price, p, per
unit that produces maximum profit; and c) the maximum profit, P.
C(q) = 70+ 15q; p=63-2q
a) The number, q, of units that produces maximum profit is q =
b) The price, p, per unit that produces maximum profit is p = $
c) The maximum profit is P = $
Answers
a) The number of units that produces maximum profit is q = 12.
b) The price per unit that produces maximum profit is p = $39.
c) The maximum profit is P = $386.
What is profit?
a) To find the number of units that produces maximum profit, we need to find the point where revenue equals cost. The revenue function is given by:
R(q) = pq = (63-2q)q = 63q - 2q²
The cost function is given by:
C(q) = 70 + 15q
The profit function is given by:
P(q) = R(q) - C(q) = (63q - 2q²) - (70 + 15q) = -2q² + 48q - 70
To find the number of units that produces maximum profit, we take the derivative of the profit function with respect to q, and set it equal to zero:
P'(q) = -4q + 48 = 0
Solving for q, we get:
q = 12
Therefore, the number of units that produces maximum profit is q = 12.
b) To find the price per unit that produces maximum profit, we substitute q = 12 into the price function:
p = 63 - 2q = 63 - 2(12) = 39
Therefore, the price per unit that produces maximum profit is p = $39.
c) To find the maximum profit, we substitute q = 12 and p = 39 into the profit function:
P = -2q² + 48q - 70 = -2(12)² + 48(12) - 70 = $386
Therefore, the maximum profit is P = $386.

A person places $741 in an investment account earning an annual rate of 5.8%, compounded continuously. Using the formula V = Pe^{rt}V=Pe
rt
, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 13 years.
Answers
The nearest cent, the amount of money in the account after 13 years is $2,094.18.
The formula for continuous compound interest is:
V = Pe^(rt)
where V is the value of the account after t years, P is the principal (initial amount) invested, e is the base of natural logarithms (approximately 2.71828), r is the annual interest rate (as a decimal), and t is the time period in years.
In this case, P = $741, r = 0.058 (since the annual interest rate is 5.8%), and t = 13. Substituting these values into the formula, we get:
V = 741e^(0.058*13)
Using a calculator, we can evaluate e^(0.058*13) to be approximately 2.8302. Then, we can multiply this value by 741 to get:
V = 741*2.8302
V ≈ $2,094.18
Therefore, to the nearest cent, the amount of money in the account after 13 years is $2,094.18.

15. Mathew waxes a car twice as fast as Andrea. If Andrea takes 24 minutes to wax the car, how much
time will they take together to wax the same car?
A) 8 minutes
B) 18 minutes
C) 12 minutes D) 16 minutes
E) 10 minutes
Answers
According to the solving time will they take together to wax the same car 16 minutes
Define minutes?The minute is a unit of time usually equal to 160 (the first sexagesimal fraction) of an hour, or 60 seconds.
According to the given information:Let's assume that Andrea takes x minutes to wax the car. Then Mathew takes x/2 minutes to wax the same car since he waxes twice as fast as Andrea.
We know that Andrea takes 24 minutes to wax the car. So we can substitute this value in the equation and solve for x.
x = 24 * 2 = 48
So Andrea takes 48 minutes to wax the car alone.
Now we can use the formula:
1/x + 1/(x/2) = 1/t
where t is the time taken by both of them together to wax the same car.
Substituting x = 48, we get:
1/48 + 1/24 = 1/t
Solving for t, we get:
t = 16minutes

A. Find the marginal cost function
Use it to estimate how fast the cost is increasing when x=4
Answers
The marginal cost function is $ 4000.72.
What is the marginal cost function?
The overall costs involved in producing an additional good are what is referred to as the marginal cost. Hence, it can be evaluated by changes in the costs associated with each extra unit. Marginal Cost is calculated as Total Expenditure Change / Unit Production Change.
Here, we have
Given: C(x) = 20+4000x+0.09x²
We have to find the marginal cost function.
We differentiate the given function and we get
C(x) = 20+4000x+0.09x²
C'(x) = 4000 + 2×0.09x
To determine how fast the cost is increasing when x=4.
C'(4) = 4000 + 2×0.09(4)
C'(4) = 4000.72
Hence, the marginal cost function is $ 4000.72.

y=-x+8 4x+y=5
Help me pls
Answers
Answer: x = -1 and y = 9
Step-by-step explanation:
To solve this system of equations, we can use the substitution method.
First, solve the first equation for y:
y = -x + 8
Now, substitute this expression for y into the second equation and solve for x:
4x + y = 5
4x + (-x + 8) = 5 (substituting -x + 8 for y)
3x + 8 = 5
3x = -3
x = -1
Now that we have found the value of x, we can substitute it back into one of the original equations to solve for y. Let's use the first equation:
y = -x + 8
y = -(-1) + 8
y = 9
Therefore, the solution to the system of equations is x = -1 and y = 9.
