The surface area of the parallelogram based prism is 1548 units squared.

The prism has 2 parallelogram base and 4 rectangular faces.

Therefore,

surface area of the prism = 2 (area of the base) + area of the 4 rectangular faces

Therefore,

surface area of the prism = 2(12 × 17) +2(19 × 13) + 2(19 × 17)

surface area of the prism = 2(204) + 2(247) + 2(323)

surface area of the prism =  408 + 494 + 646

surface area of the prism = 1548 units²

In totality the majority of the price is goes to manufacturing companies.

The selling is the process of giving the manufactured product to the public at some cost. In the clothing or garments industry, the product will be a lot of raw fabric or ready-made clothes like shirts and T-shirts.

Here the manufacturing companies give their products in the lot to the wholesalers and the retailers the margin on each product for the retailers is high but the quantity is less.

Similarly, the margin for the manufacturing companies is less but the quantity is very high or they sell in the Tons or more so they earn more as compared to the others.

Using the slope of each of the lines, the best statement that describes the their relationship is that they are: neither perpendicular nor parallel.

The slope of parallel lines are the same, while that of perpendicular lines are negative reciprocals.

Given the two lines with the following equations:

-9x+9y=1

7x+2y=4

Rewrite both in slope-intercept form as y = mx + b to determine the slope of each line:

-9x + 9y = 1

9y = 9x + 1

y = 9x/9 + 1/9

y = x + 1/9 (slope = 1)

7x + 2y = 4

2y = -7x + 4

y = -7x/2 + 4/2

y = -7/2x + 2 (slope = -7/2).

The slope of both lines are different, so they are not parallel. So also, their slopes are not negative reciprocals.

Therefore, they are neither perpendicular nor parallel.

Answer:

Speaking as an investor, this stock isn’t a good buy. There appears to be too much fluctuation in prices for the year, and it’s difficult to tell from this information whether any growth is expected on this investment for the long term.Speaking as an owner of this stock, it might not be the right time to sell. It depends on whether other opportunities are waiting. There doesn’t appear to be a trend of decrease, so it’s possible there will be more growth in the future to help cover the selling and purchase of another stock. Currently, the stock appears somewhat safe, so it would be better to be patient and wait for change.

Answer:

60m = t

Step-by-step explanation:

For " per minute ( 1 minute ) ", he can type 60 words.

For " m minutes ", he can type

m times 60

= m x 60

= 60m

Hence,

60m = t

Answer:

The answer would be B

Step-by-step explanation:

Since Miles can write 60 words PER minute. Per is a key work for multiplication. So it would be 60m = t instead of m/60 = t.

Answer: It would be 4b+44

Step-by-step explanation:

This is the distributive property! so a(b+c)=ab+ac

In this case–4b+44!

Answer:

A. 4b + 44

Step-by-step explanation:

To simplify the expression, we can distribute the 4 to each term in the parenthesis, which means to multiply 4 be each term.

4(b) + 4(11) = 4b + 44

Therefore, the correct option is A.

The equation that shows the fraction of the solar panel that is not damaged is 8 - 2 / 8 = 3 / 4

The solar panel is divided into 8 equal pieces. Two pieces are damaged.

Therefore, the equation that shows the fraction of the solar panel that is not damaged is as follows:

The amount damaged = 2

The amount not damaged = 6

Total panel = 8

Therefore,

8 - 2 / 8 =  6 / 8 = 3 / 4

Answer:

a) 27
b) 19

Step-by-step explanation:

a) Calculate the volume of the the cup using volume of cylinder equation: [tex]V = \pi r^{2} h[/tex]

Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ([tex]in^3[/tex]).
You're given diameter, so use equation [tex]d/2 = r[/tex] to find radius.
Substituting these equations will give you: [tex]V = \pi (d/2)^2 h[/tex]
However, the given volume of the sink is 3000/3[tex]\pi[/tex] or 1000[tex]\pi[/tex], meaning that you should modify your results to match this value. Do not substitute [tex]\pi[/tex] for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5 [tex]\pi[/tex]
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form:
[tex]Vsink / V cup =[/tex] # of cups.
Note the the [tex]\pi[/tex] will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.

Answer: 224 cubic feet

Step-by-step explanation: If the base of the tank is 56 sq feet in area then the dimensions could be, (2,28) (4,14) (7,8) for example. However, it doesn't really matter. It's only important that the information we know is that it is area and there are two dimensions. Since volume is determined by base x width x height, we do 56 x 4. Or using one of the factored pairs that works, for example, 8 x 7 x 4 = 224.

The function g(x) is a rational function, and none of the options represent the range of the function g(x)

The function is given as:

g(x) = -2/x + 1

The above function is undefined at point x = 0.

This is so because -2/x is undefined.

So, we have:

g(0) = -undefined + 1

g(0) = undefined

This means that the range of the function is:

(-infinity, 1) and (1, infinity)

None of the options represent the range of the function g(x)

[tex]f(x)=a|x-h|+k[/tex] looks similar to that of vertex form where a is the stretch factor, h is the horizontal translation, and k is the vertical translation.

[tex]f(x)=7|x+4|-6[/tex] would mean that the minimum point is located at [tex]x=-4[/tex] and [tex]y=-6[/tex].

Moving f(x) 2 units to the right will only affect the h value and the only way to do this is by subtracting 2 from 4. Remember that the more negative the number, the more positive or to the right the x value for the minimum/maximum is, and vice versa.

The final equation will be  [tex]f(x)=7|x+2|-6[/tex] where:

a = 7

h = 2

k = 6

Answer:

7(x + 2) - 6

Step-by-step explanation:

a(x - h) + k

the h shift it right or left where a negative number is right and the positive is left
