Calculate the amount of paint needed to paint the front of this building knowing that 0.5 kg of paint is needed per m^2
Answers
The amount of paint needed to paint the front of the building knowing that 0.5 kg of paint is needed per m^2 is 20 kg.
We know that,
Area of rectangle = L * W
where L = Length of the rectangle
and W = Width of the rectangle.
Area of triangle = 1/2 * B * H
where B = Base of the triangle
and H = Height of the triangle.
From the figure, we are given;
The front of the building has two rectangles that represent the floor and one triangle.
The rectangles are of the same size and it's given;
L = 8 m
W = 4 m
Area of rectangle = L * W = 8 * 4 = 32 m^2
The dimension of the triangle is:
B = 8 m
H = 2 m
Area of triangle = 1/2 * B * H = 1/2 * 8 * 2 = 8 m^2
The total area of the front of the building = 32 + 8 = 40 m^2
Amount of paint required
= total area of the front of the building * paint is needed per m^2
= 40 * 0.5 = 20 kg
So, 20 kg of paint is needed.
Thus, the amount of paint needed to paint the front of the building knowing that 0.5 kg of paint is needed per m^2 is 20 kg.

Answers
Answer:
x = 14 y = 37
Step-by-step explanation:
180 - (9x + 12) = 3x
180 - 9x - 12 = 3x
168 = 12x
x = 14
4y - 10 + 3(14) = 180

Your cost to produce is $30 and you need to make a markup of 30% on an upcoming bid. A competitor placed a bid for $37. Will you be able to outbid your competitor?.
Answers
No, It will not be able to outbid your competitor if your cost to produce is $30 and you need to make a markup of 30% on an upcoming bid. A competitor placed a bid for $37.
Define cost.A cost is the worth of money that has been expended to produce something or provide a service and is therefore no longer available for use in production, research, retail, and accounting. In the case of an acquisition cost, the money spent on the acquisition is considered the cost. Any system for allocating expenses to a business component is known as costing. Costing is frequently used to establish expenses for customers, distribution channels, personnel, regions, goods, product lines, processes, subsidiaries, and whole businesses.

a small dataset contains 5 numbers: 21, 32, x, 99, 40 (where x is unknown). if the average is known to be 50, what is the median?
Answers
The median of the given data set is, 40.
What is median?
The median is the value that divides a data sample, a population, or a probability distribution's upper and lower halves in statistics and probability theory. It could be referred to as "the middle" value for a data set.
Let, a data set contains 5 numbers: 21, 32, x, 99, 40.
x is the unknown number.
The average is to be 50.
Since,
Average = Sum of numbers / total numbers
50 = (21 + 32 + x + 99 + 40) / 5
50 x 5 = 192 + x
250 = 192 + x
x = 250 - 192
x = 58
Hence, the unknown number is 58.
Now to find the median,
Since median is the middle number of a data set.
So, write the numbers in ascending order.
21, 32, 40, 58, 99.
In this data set the middle number is, 40.
Therefore, the median is 40.

Balance each of the following equations
Answers
Answer:
[tex]2Sb+3I_2=2SbI_3[/tex]
[tex]P_4+3O_2=2P_2O_3[/tex]
[tex]2SO_3=2S+3O_2[/tex]
[tex]2Fe_2O_3+3C=4Fe+3CO_2[/tex]
[tex]CH_4+2O_2=CO_2+2H_2O[/tex]
Step-by-step explanation:
Each side of the equations need to have the same number of each element.
Equation 1
Since there are 2 I on one side of equation 1, and 3 on the other side, I will do the following:
[tex]Sb+3I_2=2SbI_3[/tex]
Now the number of Sb is unbalanced, so I balance it like so:
[tex]2Sb+3I_2=2SbI_3[/tex]
Equation 2
Using the same strategy, I focus on one element at a time. I can balance the P like this:
[tex]P_4+O_2=2P_2O_3[/tex]
Now, I can balance the O. There are 6 on the right, so if I put 3 on the left, there will be 6 there as well!
[tex]P_4+3O_2=2P_2O_3[/tex]
Equation 3
Starting with O this time, I put 2 on the left and 3 on the right to bring them both to 6.
[tex]2SO_3=S+3O_2[/tex]
Now there are 2S on the left and only 1 on the right, so I balance it:
[tex]2SO_3=2S+3O_2[/tex]
Equation 4
Starting with O again, there are 3 on the left and 2 on the right.
[tex]2Fe_2O_3+C=Fe+3CO_2[/tex]
Now, the Fe are unbalanced as well. There are 4 on the left and 1 on the right:
[tex]2Fe_2O_3+C=4Fe+3CO_2[/tex]
Finally, balance the C, there is 1 on the left and 3 on the right.
[tex]2Fe_2O_3+3C=4Fe+3CO_2[/tex]
Equation 5
This one is pretty hard to read, so I will assume that the equation looks like this (please comment if this is incorrect)
[tex]CH_4+O_2=CO_2+H_2O[/tex]
Let's balance the H first:
[tex]CH_4+O_2=CO_2+2H_2O[/tex]
Now the O. There are 2 on the left and 4 on the right.
[tex]CH_4+2O_2=CO_2+2H_2O[/tex]

Mack's wages in 2012 = $12 per hour
The CPI in 2001 = 94

how to use the clausius clapeyron equation to answer the following questions. derive the relationship of pressure and temperature for a system consists of vapor and condensed
Answers
The relationship between pressure and temperature for a consisting of vapour and condensed phases is [tex]l_{n}(p_{2}/p_{1}) = [ 1/T_{1}-1/T_{2}][(h_{g}-h_{f})/R][/tex].
The Clausius-Clapeyron equation is a differential equation which specifies the temperature dependence of pressure and vapour pressure. The Clausis-Clapeyron equation is named after Rudolf Clausius and Benoit Paul Emile Clapeyron.
The Clausius-Clapeyron equation at saturation temperature and pressure is
[tex]dP/dT[/tex]= [tex]h_{g} - h_{f}/T(v_{g}-v_{f} )[/tex] → 1
Assuming that [tex]v_{g} > > > v_{f}[/tex] , we write
[tex]v _{g}[/tex] = RT/P → 2 ( for both liquid and solid phases)
⇒ dP/dT = P([tex]h_{g} - h_{f}[/tex])/R[tex]T^{2}[/tex]
⇒ dP/P = dT/[tex]T^{2}[/tex]([tex]h_{g} - h_{f}[/tex]/R) → 2
By integrating 2 , we get
[tex]l_{n}(p_{2}/p_{1}) = [ 1/T_{1}-1/T_{2}][(h_{g}-h_{f})/R][/tex] → 3
Therefore, the equation to represent the relationship between pressure and temperature for a system consisting of vapour and condensed phases is equation 3 i.e. [tex]l_{n}(p_{2}/p_{1}) = [ 1/T_{1}-1/T_{2}][(h_{g}-h_{f})/R][/tex]

Answers
A guitar manufacturer sells 532,475 warranties and has to honor 12% of them. The profit the manufacturer gains from the warranties is $66,772,365 (option b)
Profit is calculated as:
Profit = revenues - total cost
While,
Revenues = number of goods sold x price per unit
In the given problem,
Revenues = number of warranty sold x price per warranty
= 532,475 x 225
= 119,806,875
Cost of honored warranty = number of honored warranty x guitar cost
= 12% x 532,475 x 830
= 53,034,510
Hence,
profit from warranty = 119,806,875 - 53,034,510
