What is the geometric mean of 4 and 10?
To find the ARITHMETIC mean of 4 and 10, you add them up and then divide by n number of values: (4+10)/2 = 7 To find the GEOMETRIC mean, you multiply 4 and 10, and then find the nth root: the square root of 40 is 6.32 (to 3 significant figures).
Find the geometric mean of 32 and 50?
Geometric mean of 32 and 50 = sqrt(32*50) = sqrt(1600) = 40
Find the least common multiple of 8 and 10?
The least common multiple is the smallest positive number that is a multiple of two or more numbers. 8: 16, 24, 32, 40 10: 10, 20, 30, 40 The least common multiple for 8 and 10 is 40.
How do you rewrite 5 over 8 and 7 over 10 with the least common denominator?
Well, honey, to rewrite 5/8 and 7/10 with the least common denominator, you first need to find the least common multiple of 8 and 10, which is 40. Then, you can rewrite 5/8 as 25/40 and 7/10 as 28/40. Voila! Now you have them both with the same denominator, making it easier to compare those sassy fractions.
Math problem help find the sum of the infinite geometric series if it exists 80 plus 40 plus 20?
160... I think. The series is 80+40+20+10+5+2.5+............ (Given the series is infinite it never ends but it gets pretty close to 160) = 159.99999999... ad infinitum [For future reference... series like this are basically equal to 2*the highest value e.g. 2*80=160]
