Infinitely many.
Start with sums of two numbers:
0 + 80, 1+79, 2 + 78 etc
then
0.1 + 79.9, 0.2 + 79.8, 0.3 + 79.7 etc
then
0.001 + 79.99, 0.02 + 79.98 etc
and so on.
Then you can have sums of 3 numbers.
and of 4 numbers, etc
You can also have Irrational Numbers in any of these sums..
To increase the number of options you can include negative numbers or subtractions:
81 - 1, 82 - 2, etc and so on with decimal fractions and irrationals in pairs, triplets, quartets, etc.
And throw in multiples. An infinite number of pairs, triplets etc.
Since the three prizes are the same, the answer is the number of combinations of 3 out of 80. That is 82160 ways.
Add three to it.
Divide it by a number that's larger than 80 i.e 80/160 = 1/2
80 miles = 128.75 km
Divide the amount of months by the number of months in a year (12). Thus the number of years in 80 months is 80/12= 6.666666666. Therefore the number of years in 80 months is roughly 6 and a half.
Since the three prizes are the same, the answer is the number of combinations of 3 out of 80. That is 82160 ways.
1 + 3 + 5 + 71 there are many combinations
some number within 80 and 110
80 + 70 = 150 40 + 25+ 15 + 70 = 150
There are multiple ways to make 80 cents using a combination of coins. One way is to use 8 dimes, another is to use 4 quarters and 2 nickels, or you could also use 40 pennies. These are just a few examples of the various combinations that can add up to 80 cents.
Add three to it.
Divide it by a number that's larger than 80 i.e 80/160 = 1/2
number of prime numbers in 71 to 80 = 3prime numbers in 71 to 80 = 71, 73, & 79
