Answer:
The answer to your question is 8.5 m
Step-by-step explanation:
Data
angle = Ф = 12°
dept = 40 m
distance from the ship to the treasure = ?
Process
To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.
tan Ф = Opposite side / Adjacent side
-Solve for Opposite side
Opposite side = Adjacent side x tanФ
-Substitution
Opposite side = 40 x tan 12
-Simplification
Opposite side = 8.5 m
By using the calculator, log 6 = 0.7781...
log 60,000 is just equal to log (6 * 10,000)
log (6 * 10,000) = log 6 + log 10,000
As we know that log 10 = 1, log 100 = 2, log 1000 = 3, and so on.
So log 10,000 = 4
Going back to our equation,
log (6 * 10,000) = log 6 + log 10,000
log 60,000 = 0.7781 + 4
So log 60,000 = 4.7781
8/12= 4/6 = 2/3 hope this helps! thank you!
Answer:
There is <u>7.5 quarts </u>of olive oil remaining.
Step-by-step explanation:

22.5 ÷ 3 =<u> 7.5 quarts remaining</u>
Ans:
Step-by-step explanation:
Let the age of oldest neighbour be x
let the age of youngest neighbour be x-30
According to question,
x+28+x-30 = 80
or, 2x +28-30=80
or,2x+28=80+30
or, 2x=110-28
or, 2x=82
or, x=82/2 = 41
Therefore, The age of oldest neighbour is 41 years
& The age of youngest neighbour= x-30 = 41-30 = 11 years!
