B describes an unknown quality.

This is because the number of pages in the book is not defined. For all we know, the book could be 20 or 2000 pages.

Hope this helps :)

After one year, the fraction of the recipe that she has not made is 896/1000 or 112/125

Fraction:

A fraction means the part of the whole thing.

For example, a pizza is divided into four equal pieces, then each piece is represented by ¼.

Given:

Your friend has a recipe book with 1000 recipes.

She makes 2 new recipes each week.

We need to find the fraction of the recipes has she not made after one year.

We know that,

1 year = 52 week

So, here they given that she will make 2 recipes per week.

So, in one year she will make

=> 2 x 52 = 104

So, the remaining recipes in the book is

=> 1000 - 104

=> 896

So, the fraction is

=> 896 / 1000

When we simplify it, then we get

To simplify, we need to find the Greatest Common Factor (GCF) of 896 and 1000, if it exists, and reduce our fraction by dividing both numerator and denominator by it. GCF = 8, and getting our simplified answer:

=> 112 / 125

If an arena hosts a concert for the same artist two years in a row and earns $1,500,000 in revenue during year one and $975,000

user100 [1]

The percentage decrease is 35%.

Step-by-step explanation:

Given,

Revenue generated in first year = Old value = $1,500,000

Revenue generated in second year = New value = $975,000

Change = New value - Old value

Change = 975000 - 1500000= -$525000

The negative sign indicates the decrease.

Percent decrease = $\frac{Change}{Old\ value}*100$

Percent decrease = $\frac{525000}{1500000}*100\\$

$Percent\ decrease=\frac{52500000}{1500000}\\\\Percent\ decrease = 35\%$

The percentage decrease is 35%.

Determine the equation of the inverse of y = 1/4 x^3 - 2

stira [4]

<h3>Answer: $y = \sqrt[3]{4x+8}$ </h3>

All of 4x+8 is under a cube root sign.

=====================================================

Work Shown:

To find the inverse, we swap x and y, then solve for y.

$y = \frac{1}{4}x^3 - 2\\\\x = \frac{1}{4}y^3 - 2\\\\x+2 = \frac{1}{4}y^3\\\\4(x+2) = y^3\\\\4x+8 = y^3\\\\y^3 = 4x+8\\\\y = \sqrt[3]{4x+8}\\\\$

------------

Side note:

If $f(x) = \frac{1}{4}x^3 - 2$ and $g(x) = \sqrt[3]{4x+8}$ , then $f(g(x)) = x$ and $g(f(x)) = x$ for all x values in the domain. Effectively, you use function composition to confirm that we have the correct inverse equation.
