I believe the answer would be infinite because there are tons of four letter words
YOUR answer is true or you can formed it with two cubr
a ^ 2 / a ^ 9
For this case what you should do is use the power properties to write the expression in different ways.
Three different ways to write the expression are:
Way 1:
a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7) = 1 / a ^ 7
1 / a ^ 7
Way 2:
a ^ 2 / a ^ 9 = a ^ (2-9) = a ^ (- 7)
a ^ (- 7)
Way 3:
a ^ 2 / a ^ 9 = a ^ 2 * a ^ (- 9)
a ^ 2 * a ^ (- 9)
Answer:
all the equivalent to a ^ 2 / a ^ 9 are:
1 / a ^ 7
a ^ (- 7)
a ^ 2 * a ^ (- 9)
Answer:
The number of earned runs is 28.
Step-by-step explanation:
Earned runs average:
The earned runs average of a pitcher is the number of runs the he/she gives each 9 innings on average.
Find the number of earned runs when the pitcher has an ERA of 2.25 after pitching 112 innings in the next season.
Solved by proportions, using a rule of three.
For each 9 innits, the pitcher gives 2.25 runs. How many runs for 112 innings?
9 innings - 2.25 runs
112 innings - x runs
Applying cross multiplication:



The number of earned runs is 28.
