The organizers of a talent show have budgeted $1800 to buy souvenir clothing to sell at the event. They can but shirts for $10 each and hats for $8 each. They plan to buy at least 5 times as many shirts as hats. The organizers used these inequalities to determine the number of shirts, s, and hats, h, that can be ordered.

$10s+8h\le 1800$

$h\ge 5s$

What error did the organizers make?

A. The first inequality should be$10s+8h\ge 1800$ .

B. The second inequality should be$s\ge 5h$ .

C. The inequalities should be equations.

D. The first inequality should be$s+h\le 1800$ .

A pin fin of uniform, cross-sectional area is fabricated of an aluminum alloy $(k=160\frac{W}{m}\cdot K)$. The fin diameter is $D=4$ mm, and the fin is exposed to convective conditions characterized by $h=220\frac{W}{{m}^{2}}\cdot K$. It is reported that the fin efficiency is ${\eta}_{f}=0.65$. Determine the fin length L and the fin effectiveness $\epsilon}_{f$ Account for tip convection.
