Rachel is collecting donations for the local animal shelter. So far she has collected , which is of what she hopes to collect. H
Rudiy27

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 x.

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:

70\%\ of\ x=245

\frac{70}{100} \times x=245

0.70x=245

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

x=\$345.

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

What is the y1 of 3x-5y=20
Aliun [14]
Unsure of what you mean by "y1."

If you wish to solve this eqn for y, do this:
-5y = - 3x + 20, 
        -3x + 20
y = ----------------   = (3/5)x - 4  (answer)
           -5

If a salesperson sells 3/4 of an acre for $80,000, what was the price per square foot rounded to two decimal spaces?
Julli [10]
Now, recalling that for 1 yard, there are 3 feet, therefore  \bf \begin{array}{ll}&#10;yards&feet\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;1yd&3ft\\&#10;(1yd)^2&(3ft)^2\\&#10;yd^2&3^2ft^2\\&#10;&9ft^2&#10;\end{array}

and keeping in mind that, there are 4840 yd² in 1 acre, then 

\bf \cfrac{\quad \frac{3}{4}~\underline{acre}\quad }{80000~\$}\cdot \cfrac{4840~\underline{yd^2}}{\underline{acre}}\cdot \cfrac{9~ft^2}{\underline{yd^2}}\implies \cfrac{\frac{3}{4}\cdot4840\cdot  9~ft^2}{80000~\$}\implies \cfrac{\frac{130680}{4}}{80000}&#10;\\\\\\&#10;\cfrac{\frac{130680}{4}}{\frac{80000}{1}}\implies \cfrac{130680}{4}\cdot \cfrac{1}{80000}\implies \cfrac{3267}{8000}~\frac{ft^2}{\$}~\approx~ 0.408375 ~\frac{ft^2}{\$}
