In triangle DEF, C is the centroid. if DM=21 find DC and CM

DC = 14

CM = 7

Step-by-step explanation:

Here, given the centroid, we want to calculate DC and CM

An important property of the centroid point is that it divides the median in the ratio 2 to 1

so DC being the longer will take the ratio of 2 while CM will take 1

Let’s work with the ratio

DC = 2/3 * 21 = 14

CM = 1/3 * 21 = 7

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
