Hamid published a book of poems. He sold 35 copies in the first week for $10 per copy. He wanted to increase the price of
Natalija [7]

After reading through the story problem, I ended up with this equation:

(35-2)(x+.5) =?

or

(35-2)(10+.5)=?

Explanation:

He sells 35 books for usual weeks. Since he is selling his books at $.50 more his average number of copies decreased by 2.

35-2 = 33

Next, we know that he adds $.50 for his price for each copy. If the price is $10 per copy than it looks like this:

$10+$.50= 10+.5

or if the price is not $10 it will be

$x+$.5= x+.5

Which is the slant height of the pyramid if Helen uses all the clay
Digiron [165]
First, find the height of the pyramid using the volume formula.
Then use the Pythagorean theorem to find the slant height.

V = (1/3)Ah

48 = (1/3)(6^2)h

144 = 36h

h = 4

Since the side of the base is 6 in., half the side is 3 in.
The height of the pyramid is 4 in.
Call the slant height S.

3^2 + 4^2 = S^2

9 + 16 = S^2

25 = S^2

S = 5

Answer: The slant height is 5 in.
