Answer:
720 possible ways
Step-by-step explanation:
The gold is awarded to the first position, the silver is awarded to the second position while the bronze is awarded to the third position.
The first position can be taken by any of the 10 runners
Now, the second position can be taken by remaining 9 runners
while the third position can be taken by the renaming 8 runners.
Thus, the number of ways in which these medals can be awarded = 10 * 9 * 8 = 720 ways
B = 2a/ch that's your answer
Answer:
The multiplicative inverse of y is
.
Step-by-step explanation:
Multiplicative inverse implies a value that you would multiply with the given value so as to give 1.
Let the multiplicative inverse of y be represented by a, so that;
a x y = 1
ay = 1
divide both sides by y to have,
a = 
Thus, the multiplicative inverse of y is
.
This is applicable to any given value. Examples:
i. Given 2, the multiplicative inverse is
.
⇒ 2 x
= 1
ii. What is the multiplicative inverse of 5?
The required answer is
.
