Answer:
Step-by-step explanation:
We have been given that there are six nickels and seven dimes in your pocket. We are asked to find the probability of getting a nickel coin both times with replacement.
Let us find probability of getting a nickel in one pick.
There are 6 nickels and total coins are 6 nickels plus 7 dimes that 13 coins.
Since the coin is returned back in the pocket, so probability of choosing 2nd nickel will be 
.
Since both terms are independent, therefore, probability the required probability will be product of and .
Therefore, our required probability would be .
Answer: 60
Step-by-step explanation:
Almost everything in this picture is irrelevant to finding the measure of x.
x = 180 - 90 - 30 = 60

Answer: yes
Step-by-step explanation:
The question given here has two parts and each part has to be answered separately. In case of both the multiplications, the answer might look to be huge but by applying a simple technique, anybody can do these multiplications without the help of any calculator.
Now let us take the case of first multiplication that is given:
50000 * 700
= 35000000
In this case all the zeroes present has to be written first and then 7 and 5 should be multiplied and put. This will get the answer easily.
Now we take the second multiplication given:
100 * 123478
= 12347800
In this case also the zeroes are simply put on the right side of the number 123478.
