Answer:
200 m s^-2.
133.33 ms^-2.
100 m s^-2.
Step-by-step explanation:
Use Newton's Second Law of motion:
Force = mass * acceleration
The force is in Newtons so the mass must be in kilograms#
100 g = 0.1 kg. So:
20 = 0.1 * a
a = 20/ 0.1 = 200 m s^-2.
We calculate the acceleration for the 150g and 200g potato in the same way.
-28 = 3 + 8(h-9)
-28 = 3 + 8h - 72 (distributive property a(b-c) = ab - ac)
-28 = -69 + 8h (combining like terms ( 3 - 72))
41 = 8h (adding 69 on both sides to isolate 8h)
/8 /8 (dividing coefficient (8) on both sides to isolate h)
5.125 = h
Therefore h = 5.125
Answer:
-3,0
Step-by-step explanation:
Divide total rocks by rocks per bag:
1479 / 12 = 123.25
They can fill 123 bags and have 3 rocks left over.
Answer:
-4x-31
Step-by-step explanation:
1) Distribute:
(-13x-15)+(9x-16)
2) Eliminate parenthesis that are not useful:
-13x-15+9x-16
3) Subtract the numbers:
-13x-31+9x
4) Combine like terms:
-4x-31
Hope this helped!
