alex needs 20 inches of ribbon for each package he wraps. he has 13 packages to wrap. how much ribbon does he need? (write your answer in feet and inches.)

21 2/3 feet

Step-by-step explanation:

20 x 13 = 260 inches of ribbon needed. There are 12 inches in 1 foot, so he will need 260/ 12 = 21 feet with 8 inches left over. The fraction would be 21 8/12 feet, which can be reduced to 21 2/3 feet

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

any options?
