y

using the ' law of exponents '

a^ m/a^ n = a^ (m - n)

so y^ 9/y^ 8 = y^ (9-8) = y^1 = y

A bag of chocolate mix weighed 1/4 of a kilogram could make enough brownies to feed 1/7 of the students at school how many bags
Hoochie [10]
A "whole" will be 7/7, or just 1 whole.

so we know one bag can do 1/7 of all students, how many will it be needed to do 7/7?

well, in 7/7 there are seven 7/7, so, 7 bags then, or one could say,

\bf \begin{array}{ccll}
\stackrel{chocolate}{bag}&\stackrel{fraction}{students}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1&\frac{1}{7}\\\\
x&\frac{7}{7}
\end{array}\implies \cfrac{1}{x}=\cfrac{\quad \frac{1}{7}\quad }{\frac{7}{7}}\implies \cfrac{1}{x}=\cfrac{1}{7}\cdot \cfrac{7}{7}
\\\\\\
\cfrac{1}{x}=\cfrac{1}{7}\implies 7=x

The elevation of Mt.Everest is 29,028 feet. The elevation of the Dead Sea is -485 feet. What is the difference in the elevation
Dvinal [7]

The difference in the elevation between Mt.Everest and the Dead Sea is 29513 feet

<h3><u>Solution:</u></h3>

Given that,

Elevation of Mt.Everest = 29028 feet

Elevation of the Dead Sea = -485 feet

To find: difference in the elevation between Mt.Everest and the Dead Sea

Therefore,

Difference = Elevation of Mt.Everest - Elevation of the Dead Sea

Substituting the given values, we get

Difference = 29028 - ( - 485)

Difference = 29028 + 485 = 29513

Thus the difference in the elevation between Mt.Everest and the Dead Sea is 29513 feet

There are 4 boys and they equally share 3 granola bars. How much does each boy gets?
OlgaM077 [116]
Each kid would get 3/4 of a bar. 3/4+3/4+3/4+3/4=4
You can solve it by just taking the number of granola bars and dividing it by the number of kids that will be equally sharing them. 3 divided by 4 is 0.75 or 3/4. ☺️
