<h3>
Answer: 0.85</h3>
Explanation:
If we start off with $100 and decrease by 15%, then we are decreasing by $15 since 15% of 100 = 0.15*100 = 15
We start with $100 and drop to 100-15 = 85. Dividing this over the original 100 gets us 85/100 = 0.85
Put another way, 100% - 15% = 1 - 0.15 = 0.85
The decimal multiplier for "decrease by 15%" is 0.85; this sort of thing is useful if you wish to apply multiple discounts to a product.
Side note: the 0.85 can be thought of as 85%, so the product's new value is 85% of its original value
Answer:
yes no yes. I was a little skeptical about 18 but nevermind
The expression for the total area of the wall is 10x.
The area of each section is 2x.
<h3>How to find the area of a rectangle?</h3>
The wall is 10 feet tall, but its length is unknown.
The whole wall is rectangular.
Therefore,'
area of a rectangle = lw
where
Therefore, the expression for the total area of the wall is as follows;
area = 10x
The area of each section can be found by dividing the length of the whole wall by 5 and multiplying by 10.
Therefore,
area of each section = x / 5 × 10
area of each section = 10 / 5 x
area of each section = 2x
