<h2>
Hello!</h2>
The answer is:
The correct option is the option D
<h2>
Why?</h2>
To calculate the acceleration, we need to use the following formula that involves the given information (initial speed, final speed, and time).
We need to use the following free fall equation:
Where:
is the final speed.
is the initial speed.
g is the acceleration due to gravity.
t is the time.
We are given the following information:
Then, using the formula to isolate the acceleration, we have:
Now, substituting we have:
Therefore, since we are looking for a magnitude, we have that the obtained value will be positive, so:
Hence, the correct option is the option D
Have a nice day!
The number of pennies in bank is 42
<em><u>Solution:</u></em>
Given that ratio of pennies to quarters in a piggy bank is 14 : 3
Let 14x be the number of pennies in piggy bank
Let 3x be the number of quarters in piggy bank
<em><u>To find: number of pennies</u></em>
Given that there are 51 quarters
number of pennies in piggy bank + number of quarters in piggy bank = 51
14x + 3x = 51
17x = 51
x = 3
number of pennies = 14x = 14(3) = 42
Thus the number of pennies in bank is 42
Answer:
3x+3
Step-by-step explanation:
add up x-3,x+6 and x
combine like terms
x+x+x-3+6=3x+3
