Answer:
- The centr<em>oid of a triangle is the intersection of the three medians of the triangle.
</em>
- <em>The centroid theorem states that the centroid of the triangle is at 2/3 of the distance from the vertex to the mid-point of the sides.</em>
<u>As per above mentioned property, we have:</u>
<u>Question1</u>
- AL = 27 - given
- AP = 2/3 AL = 2/3(27) = 18
- PL = 1/3 AL = 1/3(27) = 9
<u>Question 2</u>
- BP = 102 - given
- BP = 2/3 BL ⇒ BL = 3/2(CP) = 3/2(102) = 153
- PL = 1/3 BL = 1/3(153) = 51
16.36 times 9 which equals to 147.51 minutes
I think it’s 5 square yards I’m not sure though
Answer: He made $90 last week.
Assumption :
Let, Luis made $X last week.
He made $72 this week which is 80% of $X that he made last week
⇒ X * 80% = 72
⇒ X * 80/100 = 72
⇒ X = (72 * 100)/80
⇒ X = 90
Therefore, he made $90 last week.
To remember :
While solving this type of problems, be careful to understand which one of last time and current time is not given; just assume that one and input other conditions, the problem will be solved.
