Answer:
3 sides
Step-by-step explanation:
Interior angle = {n - 2}{180/n}
60 = {n - 2}{180/n}
Cross multiply
60n = {n - 2}180
Dividing through by 60
n = (n - 2)3
n = 3n - 6
3n - n = 6
2n = 6
n = 6/2
n = 3
Answer:A -1/3+1
Step-by-step explanation: the lope of the line is -1/3 and the Y-intercept is 1
and putting it in slope y-intercept form would be Y=-1/3+3
Given that one hose can fill a pool in 90 min and another can fill the pool in 60 minutes, to get how long the 2 hoses will take to fill the pool given that they are running together, we shall simply get the GCF of the times takes by the hoses, thus we shall have:
Multiples of 60 are
2,2,3,5
Multiples of 90
2,3,3,5
thus the GCF is: 2×3×5=30
Thus the two hoses working together will take 30 min
