How many different pairs of parallel edges are there on a rectangular solid?

Mathematics
1 answer:
Monica [59]3 years ago
4 0

Answer:

18

Step-by-step explanation:

A rectangular prism has four parallel edges along its length, four parallel edges along its width, and four parallel edges along its height.

We want to know how many different pairs of parallel edges there are.  Starting with the length, the number of unique pairs is:

₄C₂ = 6

The same is true for the width and height.  So the total number of different pairs of parallel edges is:

3 × 6 = 18

What is the selling price of a set of scrubs if the markup is 80% of the cost, and the cost is $37.99?
attashe74 [19]

Answer:

Discount = Original Price x Discount %/100

Discount = 37.99 × 80/100

Discount = 37.99 x 0.8

You save = $30.39

Final Price = Original Price - Discount

Final Price = 37.99 - 30.392

Final Price = $7.60

First of all, you would use the FOIL method for -5(a + 3). This means to just multiply -5 to all of the values in the parenthesis. This would equal:

-5a -15 = -55

Then after, you would add 15 for both sides and get -5a = -40

Divide by -5 on both sides, you get a = 8.
