The velocity when the object falls from 84 feet is 73.32 ft/sec
Step-by-step explanation:
The formula is derived from the conversion of energy principle. As the object falls the potential energy changes into kinetic energy. The right formula is:

here,
v represents the velocity
and
h represents the height in feet.
We can plug in the value of height in the formula to get the value of velocity
So, Putting h=84

Rounding off to nearest 100th
v=73.32 ft/sec
The velocity when the object falls from 84 feet is 73.32 ft/sec

Answer:
The answer to your question is Yes, he can buy it.
Step-by-step explanation:
Data
Money saved = $35
Original Price = $42
Discount = 30%
Tax = 5 %
Process
1.- Calculate the price of the Video game with the discount
$42 --------------------- 100%
x --------------------- 30%
x = (30 x 42) / 100
x = $ 12.6
Price with discount = 42 - 12.6
= $ 29.4
2.- Calculate the price of the Video game plus taxes
$29.4 ------------------- 100%
x ------------------- 5%
x = (5 x 29.4) / 100
x = 147 / 100
x = 1.47
Price plus taxes = 29.4 + 1.47
= $ 30.87
3.- Conclusion
Bruce can buy the Video game because he saved $35 and the video game plus taxes cost $30.87.
8/x-7=7/2
16=7(x-7) cross multiply
16=7x-49
-7x=-49-16
-7x=-65 divides each side by -7
-7x/7=-65/7
X=65/7
Alternative form
X=92/7
Which is 1st options in your questions.
