Answer:
-10,000 / -2000, although 10,000/2000 gives the same answer.
Step-by-step explanation:
The equations -10,000/2000 and 10,000/-2000 are negative, and negative days do not make sense, thus eliminating those answers.
Also, she wants to descend 10,000 feet, so that makes it -10,000 int he equation.
26 ⋅ 26^8
Multiply by adding the exponents:
Raise 26 to the power of 1 to get:
26^1 * 26^8
Now when you multiply the same number raised to different powers, you add the powers together:
26^1 * 26^8 = 26^(8+1) = 26^9
So 26 * 26^8 simplifies is 26^9
All up there are 20 marbles and only 6 of those are chances of winning so we make it into a fraction 6/20 then times 20 by five to get to 100 (what ever we do to the bottom we do to the top) times 6 by five giving you a fraction of 30/100 then divide 30 by 100 giving you 0.30 ANSWER EQUALS = 0.30
