Step-by-step explanation:
Given
Variation: inverse Proportion
y = 7, x = 9
Required
- Write an equation connecting y and x
- Find y when x = 21
Given that thee variation is inversely proportional;
This implies that
Convert variation to equation
----------- Equation 1
Where k is the constant of variation
Substitute 7 for y and 9 for x in equation 1
Multiply both sides by 9
Substitute 63 for k in equation 1
Multiply both sides by x
Hence, the equation connecting x and y is
Solving for when x = 21
Substitute 21 for x in the above equation
Divide both sides by 21
Divided 750 and 30 which equals 25. Multiply 25 and 10 which equals 250 then divided 375 with 250 which equals 1.5.
Yes! 5.8 is a rational number

Hi, there!
.
Assume that a contestant cannot win more than one award. Then the number of ways to choose the winner of first place is 650 since everyone has a chance to win. There are 649 ways to choose the second place winner because everyone but the first place winner is eligible. Likewise, there are 648 ways for the third place winner to be chosen. The total number of ways to choose the three awards is
