Mathematics @lemmy.ml L4r4 @lemmy.today Basal metabolic rate calculation.
cross-posted from: https://lemmy.today/post/9963785
Hi,
I've found on Wikipedia the following formula to calculate the BMR estimation
We can read just after the formula:
According to this formula, the woman in the example above has a BMR of 1,204 kilocalories (5,040 kJ) per day.
But when I take their example of a 55-year-old woman weighing 130 pounds (59 kg) and 66 inches (170 cm)
and do
((10*55)+(6,25*170)-(5*55))-161I get 1,217 and not 1,204Am I doing something wrong ?
Thanks.

Mathematics @lemmy.ml Oblomov @sociale.network A curious math problem I came up with: given a target, what's the fewest digits an integer must have (in a given base) to contain all integers from 0 to the target, as substrings?

e.g. for a target of 19 a candidate representative would be 1011213141516171819 in base 10, that has 19 digits. Can it be done in less, or is $sigma10(19) = 19$?
Can we find a general rule? Any properties of this function? -

The number pi, which is celebrated with its own day on 14 March, has inspired “Pilish” – a fiendishly challenging form of writing. There’s even a Pilish novel. Give it a go yourself, it can be strangely addictive...
