In our base-10 number system, moving a digit one place to the left multiplies its value by 10. Moving it one place to the right multiplies its value by 1/10.
You know already that 1,000 has 10 times the value of 100, and 1/10 the value of 10,000.
Answer:
0.4%
Step-by-step explanation:
In this case, because the coins have been replaced, the final probability would be multiplying the same probability six times (or raising it to exponent 6.). In other words, the probability of a dime coming out.
This probability would be the amount of dimes divided by the total number of coins, as follows:
Total coins = 10 + 8 + 2 = 20 coins.
So the probability would be: 8/20 = 2/5
The final probability would then be:
(2/5) ^ 6 = 0.004
In other words, the probability of this event occurring 6 times in a row is 0.4%
To find the last angle, add the 90 degree angle and 65 degree angle.(155)
Since a triangle has a total of 180 degrees, subtract 155 from 180 to get the third angle.(25 degrees)
To find the last side, use the pythagorean theorem(a^2 + b^2 = c^2)
a^2 + 77^2 = 85^2
solve, and you'll get the last side
