Answer:
b=20
C=160
Step-by-step explanation:
160+b= 180 (sum of angle on the straight line)
b=180-160
b=20
b+c =180 (sum of angle on the straight line)
20+c=180
c=180-20
C=160
If Hannah gives her younger sister 3 shirts, it does not matter what order she hands them to her. No matter the order, it will still be the same group of 3 shirt. Since order is not important this problem can be solved using a combination.
Specifically we are asked to find 8C3 (sometimes called "8 choose 3"). This is a fraction. In the numerator we start with 8 and count down 3 numbers. In the denominator we start with 3 and count all the way down to 1. Thus we obtain,
Answer:
1.56%
Step-by-step explanation:
A standard deck of cards has 52 cards, and 13 of these are hearts, as there are 4 suits, and 52/4=13. This means the probability of choosing a heart card from a deck of cards is 1/4, or 25%. Now to find the probability of doing this from 3 decks in a row, we simply cube 1/4 to get 1/64, and in percentage this is ~1.56%.
Answer:

Step-by-step explanation:
Power (denoted by P) can be defined as a function of work (denoted by W) and time (denoted by t) using this formula:

Unit of Work = 
Unit for Time = s
Therefore, the Unit of Power


An appropriate unit for power is:
