Points P and Q belong to AB. If AB = a and AP = 2PQ = 2QB, find the distance between: the midpoints of AP and QB. NO explanation needed. I need this fast

The distance between midpoint of AP and QB is .

Step-by-step explanation:

Given that: AB = a

                  AP = 2PQ = 2QB

Thus,

PQ = QB =

PQ + QB = +

              =

AP = a =

The distance between midpoint of AP and QB can be determined as;

+ PQ +

= + +

=

 =

Therefore, the distance between midpoint of AP and QB is .

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.
