Answer:
Peter Jonathan Winston (March 18, 1958 – disappeared January 26, 1978) was an American chess player from New York City
Step-by-step explanation:
In late 1977, Winston attended a FIDE-rated tournament at Hunter College High School in New York City. Despite being one of the highest-rated players in the tournament, Winston lost all nine of his games. A few months later, on January 26, 1978, following further surprising game losses, Peter Winston vanished and was never heard from again. According to some sources, Winston's disappearance occurred when he left his home without money, identification, or luggage during a severe winter storm. Many chess players who were close to or acquainted with Winston claim that the champion chess player's mental health had deteriorated, along with his game performance, in the last few years of his life, and that the decline in his mental health may have led to his disappearance.

Step-by-step explanation:
We are finding the quotient of the expression below in scientific notation

The following conclusions can be drawn
B.The power of 10 in the solution is –12, the difference of the original exponents.
C.The coefficient is 3, which is greater than or equal to one but less than 10.
D.The quotient is 3.0 × 
Answer:
5/4 P dollars
Step-by-step explanation:
Given that,
price of pony = P
Tax which is to added in the total price of pony = 25% of pony price
so, now total price of pony including its tax = P + 25%P
= P + 25/100 P
= P + 1/4 P
= 5/4 P dollars
= 1.25 P dollars
