Can you please post the image.
The ratio of building heights will be the same as the ratio of shadow lengths.
(taller building)/(shorter building) = (longer shadow)/(shorter shadow)
(taller building)/(84 ft) = (110 ft)/(46 ft) . . . . . . fill in the given numbers
(taller building) = (84 ft)*(110/46) ≈ 200.9 ft . . multiply by 84 ft, evaluate
The appropriate selection is
D) 200.9 ft
As each chair needs 12.6667 feet lumber.So 15 chairs will need 15*12.6667=190.0005 lumber
Voltage= Current * Resistance
Plug in your values and solve for 'x' or resistance
