Hey there!
Let's set up an algebraic equation to represent this problem:

In order to get rid of the squared, we need to take the square root of both sides, therefore, our answer is:

Your answer is the square root of 20.
Hope this helps!
Answer:
A ball is thrown vertically upward with a speed of 25.0 m/s
There is a Y axis and a X axis on the graph, they can be our equation. If the plot is (1,3) then, X=1 and Y=3, you can assume that it's X = 3. If the plot is (2,4), then X = 2, Y = 4, just divide/ simplify both sides my 2, and X = 2.
Answer:
The money Rachael plan to collect for the shelter is <u>$345</u>.
Step-by-step explanation:
<u><em>There are some data missing in the question, so below is the complete question:</em></u>
Rachel is collecting donations for the local animal shelter. So far she has collected $245, which is 70% of what she hopes to collect. How much money does Rachel plan to collect for the shelter?
Now, to find the money Rachael plan to collect for the shelter.
Let the total money Rachael plan to collect be 
The amount far she has collected = $245.
Percentage of amount she hopes to collect = 70%.
Now, to get the total money Rachael plan to collect:



<em>Dividing both sides by 0.70 we get:</em>

Therefore, the money Rachael plan to collect for the shelter is $345.
