It's when a fraction is flipped.
Example:
- 2/3..... The reciprocal for 2/3 is 3/2.
- 3/5.... The reciprocal for 3/5 is 5/3.
Answer: x= 18
Step-by-step explanation:
90+25+3x+11= 180
126+3x=180
3x= 54
x= 18
3(18)+11
65
For this, all you need is the velocity formula which is Vf = Vi + at.
Vf = final velocity.
Vi = initial velocity.
a = acceleration
t = time
Vf = Vi + at.
Vf= 0 + (-<span> 9.8 m/sec^</span><span>2) (7s)
</span>
*The 0 says that the original velocity is zero. The - 9.8 m/sec^2 is gravity because there is nothing else acting upon it, and it is negative because it is falling. The 7s is time time.*
All you have to do then, is simplify to get 68.6 m/s which is B.
