Answer:
811
Step-by-step explanation:
The place values of digits in base-3 are all powers of 3. The numbers 1, 3, 4, 9 written in base-3 are ...
1
10
11
100
You will recognize these as successive numbers in base 2. Then the 81st number of interest is written in base-3 the way 81 is written in base-2:
101 0001
It will be the sum 3^6 +3^4 +3^0 = 729 +81 +1 = 811
The 81st number is 811.
TWELVE HUNDREDS 12*100 = 1200
Answer:
maximum of 18 groups, with 75 bottled water and 8 canned food
Step-by-step explanation:
This problem is related to HCF
So you have to find the HCF of the two number of products
next, search the factors that are in common between the two numbers.
18 is going to be the number of maximum groups you can make because it is related to the combination of integers that generates the number of products.
To find the number of bottles and cans, just divide the amount you have with the amount of group.
bottles of water
cans
Hope you have a nice day!
