Given:
Initial weight of kitten = 110g
Present weight of kitten = 550g
To find:
The percentage increase in its mass.
Solution:
To get the percentage increase in its mass, we need to find the percentage increase in its weight.
Therefore, the percentage increase in kitten's mass is 400%.
Use one of the equations of motion under gravity.
s = ut + 1/2 gt^2 where s = distance, u = initial speed , t = time and g = acceleration due to gravity ( = 9.8 ms^-2)
Initial downward speed is zero so we have
19.6 = 0t + 1/2 * 9.8 t^2
4.9t^2 = 19.6
t^2 = 19.6/4.9 = 4
t = 2 seconds (answer)
Answer:
2x = 10
Step-by-step explanation:
7 + 3x = 22
-7 -7
Subtract 7 from both sides (you are trying to get the variable alone, and to do that, you have to get every other number to 0. <em>7 - 7 = 0</em>. BUT, whatever you do, you have to do to both sides.)
3x = 15
/3 /3
Divide both sides by three to get the variable alone.
x = 5
Now, plug in the value of x to the second equation and solve.
2(5) = ? --> 10
Answer:
tan ∅ = 15/8
Step-by-step explanation:
tan ∅ = 15/8
1)1) 25.3 and 2 would be 24.25
