Answer:180
Step-by-step explanation:
you start by finding the prime factorization of the number
5=1*5
9=3*3
12=2*2*3
the shortest way to find the factors is to find is most of them like example, at max, there are 2 two's, 2 three's and 1 five then you multiply them all together
4*9*5=180 and that's the answer
Answer:
8 and 4
Step-by-step explanation:
You find half of the sum and subtract half of the differece for 6 and the other 6 you add the hal of the difference.
Answer:
x = √2/2
Step-by-step explanation:
Use the identity:
arcsin x + arccos x = π/2
Therefore, we can rewrite this as:
arcsin x (π/2 − arcsin x) = π²/16
If we substitute y = arcsin x:
y (π/2 − y) = π²/16
π/2 y − y² = π²/16
0 = y² − π/2 y + π²/16
0 = 16y² − 8π y + π²
0 = (4y − π)²
y = π/4
Substituting back:
arcsin x = π/4
x = sin(π/4)
x = √2/2
The average is 4 3/4 km.
you would have to add the distance she ran for each day and then divide by the number of days she ran to find the average.
5 1/2 + 6 1/4 + 4 1/2 + 2 3/4 =19
19 (the total distance ran) divided by 4 (the number of days) = 4 3/4
