Answer:
11
Step-by-step explanation:
so we just make a system of equations:
x+y=36
say that x is the larger and y is the smaller
x-3=2y
so we can combine the equations and solve for x and y
re-arrange x-3=2y to be x=2y+3
x+y=36
x=2y+3
insert the value for x into x into x+y=36
2y+3+y=36
3y+3=36
y=11
now insert that back into x+y=36
11+x=36
x=25
Out of the two numbers x and y, 11 is the smaller number

Answer:
10,100
Step-by-step explanation:
Rounding off to the Nearest hundred is giving a number which ends as 5600 or 6700 etc. To round a number to its nearest hundred you have to first look at the tenths place ( in this case 53) if a number is 50 or above you round it to the next hundred example - 5678 rounded to the nearest hundred is 5700. If a number is below 50 example - 1348, you round it to the same hundred - 1300.
Hope this helps!
Explanation:
Mass of boy = 40 kg
Mass of box = 20 kg
Total mass = 60 kg
Initial potential energy = 0 (since height would be 0 initially)
Final potential energy = mgh
Taking g as 10 m/s²,
=> 60 × 10 × 15
= 9,000 J
So, work done = final potential energy - initial potential energy
= 9,000 J
Power = Work/Time
=> Power = 9000/25
=> Power = 360 J/s
or 360 watt.
