(t + 8) (-2) = 12
Distributive property >>> -2t + -16 = 12
Inverse operation >>>> -2t + -16+16 = 12+16
Simplify >>>> -2t = 28
Divide >>>> -2t/-2 = 28/-2
Final answer >>>> t = -14
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
21,000 + 0.07(21,000) = 21,000 + 1,470 = 22,470
Answer:
Step-by-step explanation:
Using the cosine theorem:
The angle is 114.014 degrees if we substract 90 degrees it means that at point L the plane changed its angle by 24 degrees
