Answers

In the question "Ray UW is the angle bisector of VUT. If mVUW = (4x + 6)° and mWUT = (6x – 10)°, what is the measure of WUT?" It was given that UW is the angle bisector of VUT, which means that mVUW = mWUT. i.e. 4x + 6 = 6x - 10 6x - 4x = 6 + 10 2x = 16 x = 8 Therefore, the measure of WUT = 6x - 10 = 6(8) - 10 = 48 - 10 = 38

Leiff goes online to buy a new video game. He finds a site that currently has a promotion of 15% off on all orders over $50. Leiff decides to buy his video game, with a price tag of $128, at this site because he knows that he will get the 15% discount when he checks out. Leiff pays 5. 3% sales tax on the discounted price and pays a shipping fee of $4. 75. What is the total of Leiff’s online purchase? a. $112. 84 b. $114. 57 c. $118. 82 d. $119. 32 Please select the best answer from the choices provided A B C D.

Answers

The total of Leiff’s online purchases will be $119.32.Option d is correct.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

If the video game's original price is $128 and the discount is 15%, then Leiff paid (100-15) = 85% of the original price for the item.

Consequently, the video game's price is as follows:

(0.85 x 128) = $108.80.

Leif must contribute an additional 5.3% of the new price, so

(100 + 5.3) = 105.3% of the new price

= (1.053 x 108.8) = $114.57

Including the video game's shipping cost,

114.57 + 4.75 = $119.32

Thus, the total price is $119.32

Answer:

yea what the other guy said

What process do you use to find the percent change of a quantity?

Answers

First, we need to get the amount of change:
The amount of change can either be an increase or a decrease.
It can be calculated as follows:
amount of change = $($

If the amount of change is positive, then it is an increase
If the amount of change is negative, then it is a decrease

Then, we need to convert this amount into a percentage:
Changing the amount into a percentage can simply be done by multiplying this amount by 100
This means that:
% of change = amount of change * 100

Combining the two steps:
% of change = $($ * 100

Examples:
The original price of a certain product was $10. It then became $12. Find the % of increase.
% of change = $(12-10)/(10) * 100$ = 20%
This means that the price increased by 20%

The temperature decreased from 25 degrees to 20 degrees. Find the percentage of decrease.
% of decrease = $(20-25)/(25) * 100$ = -20%
This means that the temperature decreased by 20%

Hope this helps :)
