Answer: 5.5 seconds
Since the penny is dropped and not thrown, the initial velocity is 0 and the initial height is given as 150m. Plugging these into the given equation result in 
. To find how long it will take for the penny to hit the ground we set the equation equal to zero and solve for t. Since this doesn't factor, you'll need to use the quadratic formula:
. Since time cannot be negative, the answer will be the positive 5.5 seconds.
I believe the correct answer is C
Answer:
12 and 48
Step-by-step explanation:
let n be the larger number , then 
n is the smaller number and their sum is
x + x = 60 ( multiply through by 4 to clear the fraction )
4x + x = 240 , that is
5x = 240 ( divide both sides by 5 )
x = 48
smaller number = × 48 = 12
The 2 numbers are 12 and 48
