Answer:
the last one is correct answer
Answer:
At a price of $p, a quantity, q, of the item is sold.
If q = f(p)
(a) f(150) = 2000 means at price = 150$, the number of items sold is 2000
(b) f'(150) = -25 means rate of sale is negative or the number of items sold will be decreases in future
Format: y = mx + b
m = slope, b = y intercept
Plug into the format
Solution: y = 5x + 3
We know the unit price is $1.75 and we know that she bought 55.56 cubic yards of topsoil. In order to find out how much she paid for all 55.56 cubic yards, we would multiply.
55.56 • 1.75 = 97.23
Therefore, your answer is B. When dealing with decimals, you don't move the decimal point unless exponents are involved. (:
Answer:
91.7 inches to 1 decimal place
Step-by-step explanation:
We will use Pythagoras's theorem to find the height of the pyramid.
The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.
We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in
slant height = 92.3in
Therefore height = 
The height of the pyramid is 91.73inches to 1 decimal place
