1.)
Velocity is in m/s, and acceleration is in m/s^2 like you said. Because of this, we can calculate this by dividing the speed by the time it took to get to that speed.
(20 meters/second) / 10 seconds = 2 meters/ second^2
2.)
Same thing with the first one.
(100 meters/second) / 4 seconds = 25 meters / seconds^2
D=dimes
q=quarters
if she has 12 coins then
12-d=q she has 12-d quarters
we dont know how much money she has unless we know d.
she could have 12 dimes and 0 quarters or 11 dimes and 1 quarter etc. we need more information to solve.
Answer:
we determine that none of the ordered pair is a solution of
as none of the ordered pairs satisfy the equation.
Step-by-step explanation:
Considering the equation

- Putting (-5,2) in the equation


∵ L.H.S ≠ R.H.S
FALSE
- Putting (0,-5) in the equation


∵ L.H.S ≠ R.H.S
FALSE
- Putting (5,1) in the equation


∵ L.H.S ≠ R.H.S
FALSE
- Putting (7,5) in the equation


∵ L.H.S ≠ R.H.S
FALSE
From the above calculations, we determine that none of the ordered pair is a solution of
as none of the ordered pairs satisfy the equation.
D. 70% because 45/75=0.6 or 60% and 60% doesn't equal to 70%
Hope this helps!!
Just 7 would be the answer
