Well a clock has twelve hours that make up a full circle, or 360 degrees, so you divide 12 by 360 then multiply by the degree, which in this case is 81.81 and that's the number of hours. (You figure out the minutes by looking at the decimal)
Those number are all powers of 10
10= 10^1
100= 10^2
1000= 10^3
and so on...
Answer:
39.6 cm
Step-by-step explanation:
Applying
s = 2πrθ/360................ Equation 1
Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes
From the question,
Given: r = 9 cm, θ = 252°
Constant: π = 22/7 = 3.14
Substitute these values into equation 1
s = (2×3.14×9×252)/360
s = 39.564
s = 39.6 cm
The opposite reciprocal of -1/9 is 9
So the answer is A
Answer:
-8
Step-by-step explanation:
-8m⁴ n⁴
m = 0.5 = 1/2
n = 2
Substitute
-8 * (1/2)⁴ * (2)⁴
-8 * (1/16) * (16)
-8
