Answer:
Normally, Acceleration due to gravity is
![9.8m/s^2\\](https://tex.z-dn.net/?f=9.8m%2Fs%5E2%5C%5C)
or
![10m/s^2](https://tex.z-dn.net/?f=10m%2Fs%5E2)
Step-by-step explanation:
From the web
These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance
Answer:
325 boys
Step-by-step explanation:
The ratio 5:7 represents 5+7=12 students. If we were to proportionalize this ratio to 780 students, we would multiply the ratio by 65/65 since 780/12=65.
Therefore, you have (5*65)/(7*65)=325/455 as your ratio. This means that there are 325 boys in the school
Answer:
The scientific notation is the way which scientists effortlessly handle very large numbers as well as very small numbers. In order to convert into scientific notation, move the decimal place in the number till you get the coefficient between 1 and 10. The 3,920,000,000,000 in scientific notation is 3.92 x 10^12.

Answer:
63
Step-by-step explanation:
John's percentage:
36 and 48 have a common factor of 12 so divide both of them by 12.
36/12= 3 and 48/12=4 therefore
so 36/48= 3/4 which is 75% but we don't need to focus on the percent.
Don's no. of shirts:
we know Don has 84 shirts so we say
3/4 of 84= no. of shirts that Don put in his closet
84/4=21 21x3=63
Don put 63 shirts in his closet.
Hope that helped! Anymore questions just ask! :)
Sorry a bit messy, with a ratio of 2:5:1, that means 5 would be the longest and your longest piece is 125, diving 125 by 5 gets you 25 cm, this is also your shortest piece since 1x25=25
