It should be 4 feet tall, because if the woman casts a shadow 3 times her height than a car with a 12 foot tall shadow should be four feet tall

Hello! To solve this, we can write and solve a proportion. Set it up like this: 6/18 = x/12. This is because we know the heights of the shadows, but not how y’all the car is and we need to group them up to get the right answer. Cross multiply the values in order to get 72 = 18x. Divide each side by 18 to isolate the variable. x = 4. There. The car is 4 feet tall.

A ceiling fan with 16-in. blades rotates at 45 rpm.

A. We're told the fan completes 45 full revolutions every minute. One full revolution is $2\pi\,\mathrm{rad}$ , so the fan has an angular speed of

$\dfrac{2\pi\,\mathrm{rad}}{1\,\mathrm{rev}}\cdot\dfrac{45\,\mathrm{rev}}{\mathrm{min}}=90\pi\dfrac{\rm{rad}}{\rm{min}}$

B. Throughout one full revolution of the fan, a point at the tip of one of the fan's blades travels the circumference of a circle with radius 16 in. The circumference is then $2\pi(16\,\mathrm{in})=32\pi\,\mathrm{in}$ . This means the linear speed is
