The measure of angle QPR is 30 degrees
Answer:
option: D is correct. ( (D) a markup of 15% on selling price is equivalent to a 85% markup on cost ).
Step-by-step explanation:
" Markup is the percentage difference between a product's cost and its selling price "
Since we are asked to Convert a markup of 15% on selling price to its equivalent markup on cost.
As there is a markup of 15% on selling price. Hence the cost of the product would be (100-15)%=85% of the selling price.
<em>Hence, a markup of 15% on selling price is equivalent to a 85% markup on cost.</em>
<em>Hence, option D is true.</em>
Answer:
Option A 
Step-by-step explanation:
The volume of a cone is:

The volume of a cylinder is:

Both figures have the same height h and the same radius r.
The volume of the cylinder
We want to find the volume of the cone.
Then, we find r and h:

We simplify.

Then the product of
.
We substitute this in the cone formula and get:

Answer:
The power for the volume of the cube is '3'.
Exponent form of the volume is 
Volume of the cube is
inch³.
Step-by-step explanation:
We are given,
A cube with side equal to
inches.
As we know,
Volume of a cube = 
Thus, we get,
Volume of the given cube is,
Volume =
i.e. Volume =
inch³
Thus, we have,
The power for the volume of the cube is '3'.
Exponent form of the volume is 
Volume of the cube is
inch³.
