Answer:
2.475
Step-by-step explanation:
cot(pi/7)
Taking pi = 22/7
=>cot(22/7 ÷ 1/7)
=>cot(22/7 x 7)
=>cot(22)
=>2.475
This is what i got for the
Exact form: x = -1+e
Decimal form: x = 1.71828182....
2.7 gallons.
Since the tank is already 4/5 full, only 1/5 is needed to fill it completely. As 13.5 gallons represent 5/5 (the full tank), you can take 13.5 divided by 5 to find 1/5.
