Answer:
45.05 seconds
Step-by-step explanation:
Use the formula: d = v
t +
a
d = distance v
= initial velocity (m/s)
t = time (s) a = acceleration (m/
)
m is meters and s is seconds. They are units of measurement so leave them be.
Assuming the object is simply dropped, the initial velocity is 0 since the object was not moving before it was dropped.
The distance is 725 feet, which is 220.98 meters.
The acceleration is 9.81m/
since that is the acceleration of Earth's gravity, aka free fall.
Time is what we are trying to find so just leave it as the variable t.
So plug the values into the equation:
220.98m = (0)(t) +
(9.81m/
)(t)
220.98m = (4.905m/
)(t)
45.0519877676s = t
t = 45.05s
Remember to pay attention to units because your answer will be wrong otherwise
In this question , it is given that
A painter charges by the square foot and charges you $1,875 to paint a 750 square foot rental house.
For 750 square foot, he charges $1875.
So for 1 square foot, he charges

And for 1300 square foot, he charges

150 miles= in 3 hours
150 miles/3 hours
= 50mph

1)x is less than 7
2)x is greater than and equal to -4
