Amodel of a boat is 6 inches long. if the scale is 1/3 of an inch to one foot, what is the actual length of the boat?
54 points for a

216 inches. The scale is 1/3 inches to 1 foot, which is 1/3 inches to 12 inches or 1:36. 6 times 36 is 216 inches. The boat is actually 216 inches long.

6 inches x (3 feet/ 1 inch) = 18 feet

To solve this problem, we need to set up a proportion.  Let's let x represent the number of ears of corn that Alejandra can husk in 33 minutes, or what we are trying to find.

8/24 = x/33 

Now, to simplify this proportion, we need to use cross products.  This is setting the products of one numerator and the opposite denominator equal to the product of one denominator and the opposite numerator.

8 * 33 = 24 * x

If we perform the multiplication, the resulting equation is:

264 = 24x 

Now, we have to divide both sides by 24, in order to get the x alone on the right side of the equation.

x = 11

Therefore, Alejandra can husk 11 ears of corn in 33 minutes.
