The table shows the revenue produced for the number of units sold.
u (units)/r($)
30/8
32/9
34/10
36/11
How much revenue will be produced for 45 units?
Answer: 12$
Step-by-step explanation: To find the revenue produced for 45 units, we need to find the equation that represents the relationship between the number of units sold (u) and the revenue produced (r). Based on the information given in the table, we can see that the revenue increases as the number of units sold increases. So, we can assume that there is a direct proportion between the number of units sold and the revenue produced. Therefore, we can use the equation: r = ku, where k is the constant of proportionality.
We can use any two of the given pairs (u, r) to find k. For example, using (30, 8), we have:
8 = k * 30
k = 8 / 30 = 4/15
So, the equation representing the relationship between the number of units sold and the revenue produced is: r = 4/15 * u. To find the revenue produced for 45 units, we can plug in u = 45 into the equation:
r = 4/15 * 45 = 12.
Therefore, the revenue produced for 45 units is $12.

Consider this hypothetical reaction: a 3b c 3d. assume that the equation is balanced. in which of the reactant mole ratios given will reactant b be the limiting reagent? question 12 options: 2a/7b a/b a/4b a/5b
The only option in which B can be the limiting reagent is A/B = 1.
The molecular equation for this hypothetical reaction is 3A + 3B → 3C + 3D. To determine which reactant is the limiting reagent, we must calculate the mole ratios of the reactants. In this case, we need to compare the ratio of A to B.
If we assume that the equation is balanced, then this means that there are an equal number of moles of A and B in the reaction. Therefore, the mole ratio of A to B is 1:1 (A/B = 1).
The other given options are 2A/7B, A/4B and A/5B. All of these ratios are greater than 1, meaning that B is in excess and will not be the limiting reagent. Therefore, the only option in which B can be the limiting reagent is A/B = 1.

Step-by-step explanation:
a rectangular container with a square base, an open top, and a volume of 1,372 cm3 is to be made. what is the minimum surface area for the container? enter only the minimum surface area, and do not include units in your answer.
The required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.
What is the surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In comparison to the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is significantly more complex.
The surface area of smooth surfaces, such as spheres, is determined using their representation as parametric surfaces.
Partial derivatives and double integration are used in this definition of surface area, which is based on infinitesimal calculus techniques.
So, we have the volume:
1,372 cm³
Then, h = 1372/s².
Now, calculate as follows:
4 s 1372/s^2 + s^2 = area
5488/s + s^2 = area
s^2 + 5488 (s^-1) = area
2s - 5488 s^-2 = 0
5488 s^-2 = 2s
5488 = 2 s^3
2744 = s^3
s = 14
s * h * s = 1372
Then, we will have: h = 7
Surface area = 14*14+4*7*14 = 196+4*7*14 = 588 cm²
Therefore, the required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.

a) X (−4, 2), M (0, 3)
b) X (−1, −3), M (0.5, −1.6)
c) X (6, −3), M (2, 1)
d) X (4, −3), M (0, −3)
a) Y can be found using the midpoint formula, which states that the midpoint of a line segment has coordinates equal to the average of the coordinates of its endpoints. In this case, the coordinates of Y are equal to the average of the coordinates of X and M.
The formula for finding the midpoint of two points is:
Midpoint = ( (x1 + x2) / 2, (y1 + y2) / 2 )

You spin a spinner that is equally divided into 11 parts. 3 parts are green, 3 parts are speckled, 2 parts are white, and 3 parts are yellow.
What is the probability of the spinner not stopping at a white section? Write your answer as a decimal rounded to the nearest hundredth.
The probability of the spinner not stopping at a white section 0.82.
How to find the probabilityThe probability of the spinner not stopping at a white section is 1 minus the probability of the spinner stopping at a white section.
= 1 - probability of the spinner stopping at a white section
Since there are 2 white sections out of 11 total sections, the probability of stopping at a white section
= required outcome / possible outcome
= 2/11.

Cost of shirts = x
Cost of pants = y
Lisa buys her children four shirts and three pairs of pants for $85.50.
She returns the next day and buys three shirts and five pairs of pants for $115.00.
This means,
We can make two equations.
4x + 3y = 85.50
3x + 5y = 115
Now,
4x + 3y = 85.50
4x = 85.50 - 3y
x = (85.50 - 3y)/4
Substituting in 3x + 5y = 115.
3 (85.50 - 3y)/4 + 5y = 115
256.5 - 9y + 20y = 460
11y = 460 - 256.6
11y = 203.4
y = 18.5
And,
x = (85.50 - 3y)/4
x = (85.50 - 55.5)/4
x = 30/4
x = 7.5
Thus,
The cost of the shirt is $7.5.

rafi measures the big prize wheel on a game show and calculates that it has a circumference of 56.52 feet. what is the prize wheel's radius?
The radius of the prize wheel is approximately 9.06 feet.
The circle's circumference (or perimeter) = 2πR, where R is the radius of the circle. 3.14 is the approximate value of π(up to two decimal points) value of the mathematical constant.
Again, Pi (π) is a particular mathematical constant that represents the circumference to diameter ratio of any circle.
The formula for the circumference of a circle is:
C = 2 * π * r
Where "C" is the circumference, "π" is pi (approximately equal to 3.14159), and "r" is the radius.
We can rearrange this formula to solve for the radius:
r = C / (2 * π)
Plugging in the given values:
r = 56.52 / (2 * 3.14159)
r = 56.52 / 6.28318
