Answer:
Volume = 1114.1 
Step-by-step explanation:
Recall that the formula for the volume of a pyramid is given by:
where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).
Then the square base of the pyramid has an area given by: 
Finally,we can now write the volume of the pyramid as:
Rounding the answer to a tenth of a cubic inch, we get:
Volume = 1114.1
You have to compute the prices of the two alternatives after
deducting discount based on the different percentage given.
First alternative: $19.99 – ($19.99 x 20%) = $15.99
Second alternative: $17 – ($17 x 10%)
= $15.30
Therefore, the alternative where
there will be a 10% off on the original price of $17 for a book is cheaper.
3 + (6 x p) is the answer I think
8 and 1/2 would be probably the answer
Answer:
Step-by-step explanation:
1 yard = 3 feet = 36 in
so 1 in = 1/36 yard, 1 ft = 1/3 yard.
The volume of the layer of the topsoil, is:
4 in * 28 ft * 14 ft = 4 *(1/36)*23*(1/3)*17*(1/3) yard cubed =
(4*28*14)/(36*3*3)= 1955/324=
The store only sells increments of 1/4 = 0.25 cubic yards.
we need 6.034/0.25=
So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
