A fulcrum moving a resistance of 200 g has a distance to the fulcrum of 20 cm, the effort mass of 50 g has a distance to the ful

Answer:

The ideal mechanical advantage (IMA) is 4.

Step-by-step explanation:

The ideal mechanical advantage is the ratio of length of longer lever L_e to that of shorter lever L_r

IMA \frac{L_e}{L_r}

Please refer to the image attached.

We could see that the the resistance load moves 10\ cm cm towards the fulcrum so the distance of resistance load from fulcrum = (20-10) =10\ cm

Now the as the effort force moves 40\ cm towards the fulcrum overall distance from the fulcrum to the effort force (load) =(80-40)=40\ cm

Plugging the values of the distances in IMA formula we can have.

IMA =\frac{(80-40)}{(20-10)} =\frac{40}{10}  =4.

So the IMA of the fulcrum (simple machine) = 4

27% of the students in a school are in grade 6. This is 540 students. How many students are in the school?
Anettt [7]

There are a total of 2,000 students in the school.

1.) There are 540 students in the 6th grade. 540 is only 27% of students compared to the total. To find the total students in the whole school, we divide 540 by 27%.

2.) We first change 27% into a decimal by moving the point two times to the left. (Rule to change the percent into a decimal)

27% = .27

3.) Before we divide, we remove the decimal by moving the decimal two times to the right and so do we to 540.

.27 = 27

540. = 54000.

4.) Now we have 54000 divided by 27 which give us the answer of 2,000.

Hope this Helps!!!
