Answer: 6 feet from the pivot point
<u>Step-by-step explanation:</u>
Girl's weight x distance from center = Boy's weight x distance from center
65 (7) = 75x
6.066 = x
The boy needs to be placed 6 feet from the center (aka pivot point) which is the same as saying 1 foot from the end of the seesaw.
Answer:
12
Step-by-step explanation:
We order these data:
32 minutes------------------------3 people------------------4 walls
x--------------------------------------4 people------------------7 walls
The minutes and the people are variables inversely proportional , therefore, we multiply in parallel
32 minutes*3 people=x*4 people
The minutes and the walls are variables directly proportinal; therefore, we multiply cross.
32 minutes*7 walls=x*4 walls
Therefore:
32 minutes*3 people*7 walls=x*4 people*4 walls
x=(32 minutes*3 people*7 walls) / (4 people* 4 walls)
x=42 minutes.
Answer: the time will be 42 minutes.
