Answer:
2:50
Step-by-step explanation:
On an ordinary clock, there are 24 hours.
1) 6/24 = 0.25 (The percentage in which the day has passed)
2) 10 (total hours in a day in the decimal clock) * x 0.25 = 2.50
3) 2.5 Hours. On a typical clock, that would read 2:30, however, because the decimal clock proposes that there are 100 minutes in one hour, it will be 2:50, Therefore, the clock will display 2:50
The answers are revealed by subtracting the right side of the equation from both sides.
(a) (2x+3x-6) -(10+4x) = 0
... x -16 = 0 . . . . one solution; neither
(b) (17+5x) -(23+4x-6+x) = 0
... 0 = 0 . . . . . . . an infinite number of solutions; an identity
(c) (7x+4) -(5x+8+2x-10) = 0
... 6 = 0 . . . . . . . no solutions; a contradiction
Step-by-step explanation:
The midline is the average of the lowest point and the highest point.
y = (4 + 6) / 2
y = 5
The amplitude is the distance from the midline to the lowest/highest point:
a = 5 − 4 = 1, or a = 6 − 5 = 1
It's also half the distance between the lowest point and the highest point:
a = (6 − 4) / 2
a = 1
The period is the time it takes to complete a full cycle, so the period is 12 hours.
