It has to be 20 because if you calculate 80 divided be 16, that’s is 5 and if you add five four time that’s would lead the 16 to 20 and lead the 80 to 100 because 5 times 4 equals 20

A 76 foot piece of rope is cut into three pieces where one piece is three times longer than the other two equal pieces. How long

jonny [76]

Let the length of one of the shorter pieces be $\ell$ . Then, we know that two of the pieces are that length, and the third piece is $3 \ell$ . Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for $\ell$ , and then plug that back in to the desired lengths:

$3 \ell + \ell + \ell = 76 ft.$
$5 \ell = 76 ft.$
$\ell = 15.2 ft.$

Shorter pieces: $\ell = \bf 15.2 ft.$
Longer piece: $3 \ell = \bf 45.6 ft.$

Answer:

the MAD to this set is 6.75

Step-by-step explanation:

The process is pretty long on how to find the MAD but here it goes.First you find the mean of the set( 70 )then you find the distances between all the numbers and the mean( 68 is 2 values away from being 70 so that would be 2) than you add all the distances together than divide that number by the amount of values are in the set.

hope that makes sense have a good day
