a computer monitor is regularly priced at $320. during a two day sale the price was decreased to$240. which of the following is the percentage decrease of the monitors price during the sale?

Answers

In the question there are several information's worth taking note of. based on the given information's the required answer can be easily deduced. It is already given that the regular price of the computer monitor is $320. It is also given that during a two day sale the monitor price was decreased to $ 240. It is required to find the percentage decrease in the price of the monitor during the sale period.
Difference in price of the monitor = (320 - 240) dollars
      = 80 dollars.
Percentage of price decrease of the monitors = (80/320) * 100
   = 100/4
   = 25
So the price of the computer monitor was reduced by 25%.

Name the shaded angle in three different ways

Answers

Answer:

1. "angle HGJ" or "angle JGH" (∠HGJ or ∠JGH)

2. "angle G" (∠G)

3. "angle 3" (∠3)

Step-by-step explanation:

Three ways the shaded angle can be named:

1. We can use capital letters to name the shaded angle. The middle letter indicates the vertex. Thus, we would name the shaded angle as: "angle HGJ" or "angle JGH". G is the middle letter, which indicates the vertex of the angle. Most often, the symbol "∠" is usually used to represent the word "angle". In short form, the shaded angle can be named as:

"∠ HGJ" or "∠ JGH"

2. The shaded angle can also be named according to the vertex. Thus, G is the vertex. The angle can be named "angle G" or "∠G"

3. Numbers can be placed at the vertex of the angle, and named accordingly. Thus, the shaded angle of which the vertex is labelled "3" can be named as "angle 3" or "∠3"
