u need to find surface area which is 2(lw)+2(lh)+2(wh)

so is 2(30x54)+2(30x10)+2(54x10)= 2(1620)+2(300)+2(540)=

3240+600+1080=4920 square feet

divide the amount u need by the amount per gallon so is 4920/400 which is 12.3 gallons

Solve the equation (1 + x²)dy +xydx= 0​
Tatiana [17]

Answer:

y=\frac{c}{\sqrt[]{x^2+1} }

Step-by-step explanation:

(1 + x²)dy +xydx= 0​

(1+x^2)dy=-xydx\\\frac{1}{y}dy=\frac{-x}{x^2+1}dx\\

Integrate both side

lny=-\frac{1}{2} ln(x^2+1)+c\\y=\frac{c}{\sqrt[]{x^2+1} }

Scilla [17]
<span>Ariel deposited 100$ into a bank account. Each Friday she will withdraw 10% of the money in the account to spend. Ariel thinks her account will be empty after 10 withdrawals. Do you agree? Explain

=> 100 dollars = the money of Ariel in the bank
=> 10% = he withdraw every Friday
10% of 100 is:

median before: 25

median after: 25
