The operation applied is division.
a simple explanation is that the quantity decreases if you move the decimal to the left, which is the case for division
A power of 10^-4 is involved (you get a negative sign if you shift the decimal to the left: which is another explanation to the above question)
To work out the distance of the path, you need to find out the circumference.
Formula for circumference = pi multiplied by the diameter
So you simply do:
pi multiplied by 1.4 miles
And you should get:
4.39822971503... miles
Simply round the result to an appropriate value (e.g. 3 decimal places).
Answer: 4.398 miles (to 3dp)
Hope the answer helps :)
Answer:
745.5 ft
Step-by-step explanation:
Reference angle (θ) = angle of depression = angle of elevation = 28° (alternate angles are congruent)
Opposite side = 350 ft
Hypotenuse = x
Apply the trigonometric function, SOH:
Sin θ = Opp/Hyp
Sin 28° = 350/x
x = 350/Sin 28
x = 745.5 ft (nearest tenth)
The correct answer is C
x=-4 x=2
let me know if you need the work
A) 3/7 is greater because 2 divided by 5 is .40 and 3 divided by 7 is .42 rounded
b) 3/10 = .3, 2/5 = .4, 14/30 = about .46, 1/2 =.5, and 8/15 = about .53
hope this helps :)
