We know that
• The total is nine starters.
,
• The coach wants to choose three.
Given that the player cannot include repetition, we solve this problem as a combination because the order does not matter.
Where n = 9, and r = 3. Let's replace these values.
<h2>Hence, there are 84 different ways to choose the first three.</h2>
Answer:
180 gallons
Step-by-step explanation:
Each hour, 8 gallons were lost. Thus, in 6 hours,
6 * 8 = 48 gallons were lost
After 6 hours, 132 gallons remained, so before this 6 hours, there were more 48 gallons in it. Thus,
Original amount was 132 + 48 = 180 gallons
Originally, 180 gallons of water was in the pool
Answer:
5-46i
Step-by-step explanation:
1. Multiply (10-4i) and (4-5i), I recomnd using foil:
40-50i-16+20i^2 + (-15+20i)
2. Remove the parenthesis around -15+20i
*we can do this since there is a "+":
40-50i-16+20i^2 + (-15)+20
3. Simplify i^2
* i^2 is -1 by textbook defination:
40-50i-16+20(-1) + (-15)+20
4. Simplify
40-50i-16-20 + (-15)+20
6. Combine like terms:
-5-50i-16i+20i
5-46i
And the problem is done
