Answer:
the answer may be this: 8 √3
Answer: 10
Step-by-step explanation:
Answer:
Final answer is 47.5%.
Step-by-step explanation:
Let the missing percent is x.
Then x percent of 40 can be written as: 
.
Given that resulting percent value is 19.
So we can set both equal.
So the final answer is 47.5%.
You would have to do 15 - 2 because according to PEMDAS you do parentheses first and you would do the multiplication and division
question 6,
Answer : 35.7 degree from north
Step-by-step explanation:
Bearing is angle w.r.t the north.
To calculate this angle we need the angle of the triangle in the diagram.
We know two sides of the triangle the base (18) and Perpendicular(25).
Tan(x) = 25/18
arctan(25/18) = 54.24 deg
Subtracting from 90 to get angle w.r.t north 90-54.24 = 35.7
Question 7,
Solution: 33.12
Explaination
calculate the length of the straw within the glass.
It makes a right angle triangle with the glass, where the length is the hypotenuse.
the base is 9 (radius *2 = 4.5*2)
using Cos(x) = base / hypotenuse
cos(72) = 9 /Hypotenuse
Hypotenuse = 9/cos(72)
Hypotenuse = 29.12
total length is hypotenuse + the length protruding out(4)
29.12 + 4 = 33.12
