Answer:
the opposite of -40 is 40
Step-by-step explanation:
(4/3)–1 = 3/4 and (1/4)–1 = 4/1
now we have,
(3/4 - 4)–1 = (-13/4)–1
= -4/13
you turn 1 and 1 over 5 into 6 over 5. then divide.
12 divided by 6 over 5 equals 10
What is 7x5x4, it is 140 so the volume is 140in^3 its a pretty simple problem
Step-by-step explanation:
Let θ be the angle of depression i.e the angle between the horizontal and the observer's line of sight.
tanθ= (Height of the light house)/(Horizontal distance of ship from the base of light house)
∴tanθ=88/1532=0.0574
∴θ=tan−1(0.0574)=3.290(2dp)
