A package of pencils cost $6.25 per set at an office supply store. Which equation can be used to determine the price, P, of n se
2 answers:
Answer:
<h2>P = 6.25n</h2>Step-by-step explanation:
The problem says that each set costs $6.25, and <em>n </em>refers to sets of pencils.
So, we know that "per" refers to multiplication, because if each set of pencil costs $6.25, then a <em>n </em>quantity of pencils will be the sum of $6.25 <em>n </em>times, which is the definition of multiplication. So, the equation that correctly determined the price is:
The price is $6.25 per set of pencils, that is what this equation says.
Therefore, the right answer is the second one.

Answer:
62m³
Step-by-step explanation:
The question is incomplete. Find the diagram of the prism attached below.
Volume of a Prism = Base area × Height
Given height = 9m
Since the prism is a triangular based prism,
Base area = area of the equilateral triangle = 1/2bh
base of the triangle = 4m
Height can be gotten using Pythagoras theorem.
Slant side of the triangle is the hypotenuse = 4m
Adjacent = 1/2 of the base = 1/2(4)= 2m
Height = √4²-2²
Height = √16-4
Height of the triangle= √12 m
Base Area = 1/2×4×√12
Base Area = 2√12 m
Volume of the prism = 2√12 × 9
= 2×2√3×9
= 36√3 m³
= 62.2m³
Volume of the prism is approximately 62m³
