Answer:
$ 154
Step-by-step explanation
Let the value of suitcase=x
x × 4.5% = 6.93 (converted the question into equation)
x × = 6.93 (converted the percentage into fraction)
x = 6.93 x (took reciprocal of 4.5/100 after moving it to the other side of the equation)
x = (multiplied the values)
x = 154 $ (simplified the fraction)

We are given
Tobias dropped a tennis ball from a height of 60 meters. The time in seconds it takes for the ball to fall 60 feet is 0.25(radical60).
so, time is
we have to approximate it's value
First approximation set:
we know that
we can take sqrt all the sides
we can simplify it
Divide all sides by 4
Second approximation set:
Divide all sides by 4
Third approximation set:
Divide all sides by 4
so, we get
