Answer and explanation :
We have given that the expression 
We have to prove L.H.S = R.H.S
Lets take L.H.S

It can be written as
( As in multiplication exponent are added )
So
= R.H.S
Hence proved
Total number of coins in question = 275
Number of quarters among the total coins = 120
Then
Remaining number of coins = 275 - 120
= 155
Percentage of coins that are nickel = 20%
Then
Number of coins that are nickel = (20/100) * 155
= 155/5
= 31
Remaining number of coins = 155 - 31
= 124
Ratio of dimes to pennies = 1:3
Let us assume the common ratio to be = x
Then
x + 3x = 124
4x = 124
x = 124/4
= 31
So
The number of pennies = 3 * 31
= 93
From the above deduction we can conclude that there are 93 pennies. The correct option among all the options given in the question is option "C".
12 x 2 x 1
4 x 3 x 2
6 x 2 x 2
1 x 24 x 1
-6 x 2 x -2
- 4 x 3 x -2
- 12 x 2 x =1
=1 x 24 x -1
Answer:
its irrational if the number goes on forever my g
Answer:
30sequences
Step-by-step explanation:
Using nx (n-1)
And
n is the number of ternary digits in the number.
So For 6 digits n is 6 so the number of numbers that have exactly one 1 AND exactly one 2 is 30.
That is 6(6-1)= 30
