If sinA+cosA=\(\sqrt{3}\), then find the value of tanA+cotA+2sinAcosA
The value of \(4\frac{1}{6} \div 25 \times 75 \div \frac{1}{5} \text{ of } 125\) is:
\(\frac{1}{3}\)
\(\frac{1}{4}\)
\(\frac{1}{6}\)
\(\frac{1}{2}\)
Pipe X can fill a tank in 9 hours and Pipe Y can fill it in 21 hours. If they are opened on alternate hours and Pipe X is opened first, in how many hours shall the tank be full?
\(10\frac{3}{7}\)
\(12\frac{3}{7}\)
\(9\frac{3}{7}\)
\(11\frac{3}{7}\)
