This means 5 meters/20 steps = x/1,000 steps. 20 times 50 is 1,000, so 5 times 50 is 250 meters. 5/20 can be also reduced to 1/4 = x/1000. Use cross products rule to get 4x = 1,000. Divided both sides by 4 to get x = 250 meters.
Answer:
25%
Step-by-step explanation:
The percent of increase can be calculated using following formula:
![\text{Percent Increase}=\dfrac{\text{Final Amount-Initial Amount}}{\text{Initial Amount}}\cdot 100\%.](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20Increase%7D%3D%5Cdfrac%7B%5Ctext%7BFinal%20Amount-Initial%20Amount%7D%7D%7B%5Ctext%7BInitial%20Amount%7D%7D%5Ccdot%20100%5C%25.)
In your case,
- Initial amount = 12 students;
- Final amount = 15 students,
then
![\text{Percent Increase}=\dfrac{15-12}{12}\cdot 100\%=\dfrac{3}{12}\cdot 100\%=\dfrac{1}{4}\cdot 100\%=25\%.](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20Increase%7D%3D%5Cdfrac%7B15-12%7D%7B12%7D%5Ccdot%20100%5C%25%3D%5Cdfrac%7B3%7D%7B12%7D%5Ccdot%20100%5C%25%3D%5Cdfrac%7B1%7D%7B4%7D%5Ccdot%20100%5C%25%3D25%5C%25.)
Answer:

Step-by-step explanation:
From the given information:
The cotton count of the piled yarn is the ratio of the simple weight in (g) with the length by the simple length with weight.
Mathematically:
![Cotton count = \dfrac{simple \ weight \ in (g) \times \ length }{simple \ length \times unit \ weight }](https://tex.z-dn.net/?f=Cotton%20count%20%3D%20%5Cdfrac%7Bsimple%20%5C%20weight%20%5C%20in%20%28g%29%20%5Ctimes%20%5C%20length%20%7D%7Bsimple%20%5C%20length%20%5Ctimes%20unit%20%5C%20weight%20%7D)
![Cotton count = \dfrac{1 \times 0.001 }{0.108 \times 20}](https://tex.z-dn.net/?f=Cotton%20count%20%3D%20%5Cdfrac%7B1%20%5Ctimes%200.001%20%7D%7B0.108%20%5Ctimes%2020%7D)
