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
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
80
There are 80 protons in mercury-204 because the atomic number of mercury is 80, which is equal to the number of protons in its nucleus.
u can make 4 partitions in 80 gb harddisk of 19000! simple
The proper answer is 80%. Why because .8 is in the tens place and has one place value which would make it easier for you to understand so what i mean is that .8 is in the tens place so is a number 1-10 and then just look at the number you have and take out the decimal and put the percentage in. Many people get messed up and put .8 as 80% but only .80 would make 80%Did this help? Hope it did!
800 / 80 = 100
