Answer:
Demand curve for a perfectly competitive firm is perfectly elastic because the perfectly competitive firm can sell any quantity it desires at the prevailing market price. A perfectly competitive firm's demand curve is horizontal line which is equal to equilibrium price of the entire market. Horizontal demand curve depicts that the elasticity of demand for the product is perfectly elastic which means that if any individual firm charged a price a little above market price, it will not sell any products.
The demand curve for monopolistically competitive firm is less elastic than that for a perfectly competitive firm and it slopes downward. This is because this firm can raise its price without losing all of its customers or it can lower the price and gain more customers. These firms have a limited capability to impose the price of its goods. By distinguishing its products, firms in a monopolistically competitive market make sure that its products are imperfect replacement for each other. Consequently, business that works on its branding can raise its prices without endangering its consumer base.
Answer: The volume of the stone is 576 cubic inches
Step-by-step explanation: The dimensions of the tank are given in feet and inches, hence we shall use the lower of the unit of measurement that is, inches. Note that 1 foot equals 12 inches, so the length is 2 feet times 12, which equals 24 inches. Also the width is 1 foot times 12 which equals 12 inches. Then the tank is filled with water up to a depth of 8 inches , so the volume of water in the tank can be calculated as follows;
Volume = L x B x H
Where Length = 24, Width = 12 and Height = 8
Volume = 24 x 12 x 8
Volume = 2304
At 2304 cubic inches, a stone is placed in the water tank and the water level rises by 2 inches which implies that the depth is now 10 inches. With the addition of the stone, the dimensions are now shown as;
Length = 24, Width = 12, and Height = 10
Volume = L x W x H
Volume = 24 x 12 x 10
Volume = 2880
With the rise in volume of water in the tank, the difference (which is the volume of the stone) now is Volume with stone minus volume without stone, that is
Volume of stone = 2880 - 2304
Volume of stone = 576
Therefore the volume of the stone is 576 cubic inches
I think 12 minutes because if you take 9 divide it by 3/4 you get 12
Neither...
205/1000 equals .205
So they are both the same.
Hope this helps -J
