<em><u>Division equation is:</u></em>
There are 2816 calories in whole pizza
<em><u>Solution:</u></em>
Given that,
A 14- inch pepperoni pizza is sliced into 8 equal pieces
One slice contained 352 calories
Therefore,
1 slice = 352 calories
Let "c" be the calories
Given that there are 8 equal pieces
<em><u>Therefore, calories in 8 pieces are:</u></em>
Calories in 8 pieces = 8 x calories in 1 piece
Thus the division equation is:
Therefore,
Thus there are 2816 calories in whole pizza
Answer:
Time at which the hammer reaches the ground is 2.3 seconds.
Step-by-step explanation:
We are given the formula as, .
It is known that, when height i.e. meter, then velocity
m/sec.
So, we get the formula as, .
Now, when the hammer hits the ground, the height meter.
Thus, we have,
⇒
⇒
⇒
i.e. t= ±2.3 sec
Since, time cannot be negative.
So, t= 2.3 sec
Hence, the time at which the hammer reaches the ground is 2.3 seconds.
