Answer:
2.7 seconds
Step-by-step explanation:
We are asked to find how many seconds it takes for an object to fall from a height of 120ft. We will use the given formula, t=h−−√4. Substituting h=120, we find
t=120−−−√4=2.7
So, the pebble reaches the ocean after 2.7 seconds.
Answer: a.

Answer:
81 books
Step-by-step explanation:
If you divide 731 into 9 you'll get 81.2
so that means you have 2 books left over that wont be on the shelf
so you'll have to round to 81
The solutions of the equations of the situation can be:
z = 1 , y = 5, x = 4
z= 2 , y = 3, x = 5
z=3 , y = 1, x = 6
z = 0 , y = 7, x =3
The question can be expressed as a equation
6 x + 8 y + 10 z = 84
also, x + y + z = 10
⇒ x = 10- y - z
Putting it in first equation,
6(10 - y - z ) +8y + 10z = 84
⇒ 60 +2y + 4z = 84
⇒2(y + 2z ) = 14
⇒ y + 2z = 7
Now putting
z = 1 , we get y = 5,
z= 2 , y = 3
z=3 , y = 1
z = 0 , y = 7
So, only 4 possible solutions.
Therefore, there can only be 4 possible solutions for the equations.
