Answer:
$190
Step-by-step explanation:
The salvage value can be modeled by the function y = kx, where x is the number of tons of steel, y is the salvage value, and k is the price per ton.
Pick a point from the table, (2, 380), and evaluate the function y = kx at this point.
Therefore, the price per ton for raw steel is $190.
Final answer:
Based on the provided table, the price per ton for raw steel is calculated by dividing the salvage value by the tons of steel. The consistent result across the table is $210 per ton, making the correct answer C. $210.
Explanation:
To determine the price per ton for raw steel based on the table provided, we need to analyze the consistent increase in salvage value with respect to the tons of steel. Looking at the table:
For 2 tons of steel, the salvage value is $420.
For 4 tons of steel, the salvage value is $840.
For 6 tons of steel, the salvage value is $1,260.
For 8 tons of steel, the salvage value is $1,680.
For 10 tons of steel, the salvage value is $2,100.
To find the price per ton, we can divide the salvage value by the number of tons of steel. For example:
$$420 \div 2\text{ tons} = $210 \text{ per ton}$$
The price per ton remains consistent for every salvage value given, confirming that the price per ton of raw steel is $210.
Therefore, the correct answer is C. $210.
Ted picks 6 flowers with 4 petals on each flower. Bill picks 3 flowers with 8 petals on each flower. Jon picks 2 flowers with 12 petals on each flower. Ted says they all have the same amount of petals. Is Ted correct?
solve the equation
5/13t = -9
5/13t = -9
Isolate the t. Multiply 13/5 to both sides
5/13t(13/5) = -9(13/5)
t = -9(13/5)
t = -117/5
Simplify.
t = -23.4
t = 23.4 is your answer

What is the volume of the cylinder
Given cylinder has diameter 16ft and height 10ft.
Radius of the cylinder = 16/2 = 8 ft.
We need to find the volume of cylinder.
Volume of the cylinder (V) = [tex]\pi r^2h[/tex]
Where r is the radius of the cylinder and h is the height of the cylinder.
Plugging values of r=8 and height h=10 in above formula, we get
V = [tex]\pi (8)^2(10)[/tex]
V= [tex]\pi 64 \times 10[/tex]
V=[tex]\pi \ times 640[/tex]
Plugging π =3.142
V= 3.142 × 640
V ≈2010.88.
In the given options it's nearly equal to 2010.62.
Therefore, Volume is 2010.62 ft^3.What is 3.993 rounded to the nearest hundredth

Step-by-step explanation:
what is 6.25 divided by 2.5
To divide 6.25 by 2.5, you can multiply both numbers by 10 to make it 62.5 divided by 25, which equals 2.5. Thus, 6.25 divided by 2.5 is 2.5.
To find this, we divide 6.25 by 2.5. First, we can make the divisor a whole number by multiplying both the divisor and dividend by 10, which will not change the value of the quotient:
6.25 × 10 = 62.5
2.5 × 10 = 25
Now, we divide 62.5 by 25:
62.5 ÷ 25 = 2.5
Therefore, 6.25 divided by 2.5 is 2.5.
If the polygon is translated 3 units down and 4 units left, what will the coordinates of the new image be? Use prime notation in expressing the new coordinates.
Final answer:
To translate a polygon 3 units down and 4 units left, subtract 4 from the x-coordinate and 3 from the y-coordinate of each vertex. For example, the vertex (3, 0.4) would become (-1, -2.6) in prime notation after the translation.
Explanation:
If a polygon is translated 3 units down and 4 units left, the coordinates of the new image would change respectively. To find the new coordinates after the translation, the x-coordinate of each vertex will decrease by 4 (since it is moving left) and the y-coordinate will decrease by 3 (since it is moving down). For example, if the coordinates of a vertex are (x, y), after the translation, the new coordinates will be (x - 4, y - 3), which we denote using prime notation as (x', y').
So, if we are given the initial coordinates of the first vertex as (3, 0.4), then after the translation, the new coordinates will be:
x' = 3 - 4 = -1
y' = 0.4 - 3 = -2.6
Therefore, the new coordinates are (-1, -2.6), using prime notation to represent the translated vertex.

A barber cuts 3 people hair in 35 min . Each hair cut takes at least 10 min, and the first haircut takes the most time .list one way the barber could cut 3 people's hair given this information
One way the barber could cut 3 people's hair in 35 minutes is by spending 15 minutes on the first haircut and 10 minutes each on the second and third haircuts.
If a barber cuts 3 people's hair in 35 minutes and each haircut takes at least 10 minutes, the timing could look as follows: The first haircut, taking the most time, could be 15 minutes. The second haircut could take 10 minutes, which is the minimum time per haircut. The third haircut would also take 10 minutes. This allocation adheres to the conditions that the first haircut takes the most time, and each haircut takes at least 10 minutes.
Total time spent would be 15 minutes + 10 minutes + 10 minutes, which equals 35 minutes.
1. A college newspaper, The College Spy, has a fixed production cost of $70 per edition and it costs 40¢ per copy to print and distribute. The College Spy sells for 50¢ per copy.
a. What is the cost expression for the newspaper?
b. What is the revenue expression for the newspaper?
c. Put the cost and revenue expressions into an inequality that would represent a successful newspaper.
d. How many copies should be sold to make a profit? Show all work! An answer with no work will receive 0 points.
e. Now go back to your answer for d. On every line of your solution write what property of math you would use to justify the transformation that occurred.
a. What is the cost expression for the newspaper?
The cost would be the sum of fixed cost and the variable cost. The fixed cost
is 70 while the variable cost is 0.40 x, where x stands for the number of
copies made. That is:
Cost = 70 + 0.40 x
where x = number of copies made
b. What is the revenue expression for the newspaper?
The revenue would simply be the product of selling price and number of copies sold or made, that is:
Revenue = 0.50 x
c. Put the cost and revenue expressions into an inequality that would represent
a successful newspaper.
To have a successful newspaper, the difference of revenue and cost must be
greater than 0, that is:
Revenue – Cost > 0
0.50 x – (70 + 0.40 x) > 0
d. How many copies should be sold to make a profit? Show all work! An answer
with no work will receive 0 points.
From the above equation, we solve for x.
0.50 x – (70 + 0.40 x) > 0
0.50 x – 70 – 0.40 x > 0
0.10 x > 70
x > 700
Number of copies made should be more than 700 copies
e. Now go back to your answer for d. On every line of your solution write what
property of math you would use to justify the transformation that
occurred.
0.50 x – (70 + 0.40 x) > 0 Distribution property
0.50 x – 70 – 0.40 x > 0 Addition property
0.10 x > 70 Addition property
x > 700 Division property
Final answer:
The cost expression for the newspaper is $70 + $0.40c. The revenue expression is $0.50c. A successful newspaper would have $0.50c > $70 + $0.40c. To make a profit, 700 copies should be sold.
Explanation:
a. The cost expression for the newspaper can be calculated by adding the fixed production cost per edition to the cost of printing and distributing each copy. So the cost expression is:
Cost = $70 + $0.40c
where 'c' represents the number of copies.
b. The revenue expression for the newspaper can be calculated by multiplying the selling price per copy by the number of copies sold. So the revenue expression is:
Revenue = $0.50c
c. To represent a successful newspaper, the revenue should be greater than the cost. So the inequality would be:
$0.50c > $70 + $0.40c
d. To calculate the number of copies needed to make a profit, we need to find the point where the revenue is equal to or greater than the cost. So we set the inequality from part c to equality and solve for 'c':
$0.50c = $70 + $0.40c
$0.10c = $70
c = $700
e. At every step in the solution, we used the property of equalizing the equation by adding or subtracting the same value on both sides, and also dividing by the same value on both sides.
