Answer:

its a prism

Step-by-step explanation:

to find area of all the sides, you multiply the bottom and top measurements.

12 x 7 is 84cm^{2}

12 x 9 is 108cm^{2}

9 x 7 is 63cm^{2}

for surface area, add the area of all the faces

63x2+108x2+84X2=510

volume is length x width x hight

12 x 9 x 7 = 756 cm^{3}

Answer:

It is a Cuboid

Area of the base = 12x9

Area of the top = 12x9

Area of the right lateral faces = 9x7

Area of the left lateral faces = 9x7

Area of the front face = 12x7

Area of the rear face = 12x7

Total surface area is the sum of above (please do it yourself)

The volume = base surface Area x height

= 12x9x7 = 756

Be reminded to put in the right unit for Area and volumn

Answer: Part a) 375 pounds, Part b) 8 words

Step-by-step explanation:

a)

<u />

Since n represents the number of words there are, we can plug in 20 for n into the equation to get:

C = 15*20 + 75 pounds

C = 300 + 75 pounds

C = 375 pounds

b)

Since C represents the cost of the advert, we can plug in 195 for C into the equation to get:

195 = 15n + 75

Subtract 75 from both sides:

120 = 15n

Divide both sides by 15:

n = 8 words

4.06 Question 6
polet [3.4K]

Answer:

If we are to make x small rugs, each of which takes 2 hours to dye, then the total time taken to dye the small rugs is 2x. Similarly for the y large rugs which each take 3 hours to dye, the total time for dyeing the large rugs is 3y. Therefore the total for all sizes of rugs is 2x + 3y. Finally, we have a maximum of 60 available hours for the dyeing, so the total time cannot exceed 60, and the final inequality is

2x + 3y < 60
