For Y=2x+10 X=y/2 -5. Second x/3
Answer:
y= x+7
Step-by-step explanation:
plug in 0 to x and get 7 for y
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
Answer:
I'm gonna go with D its the smartest answer
Answer:
69.21
Step-by-step explanation:
We know one hour is 60 minutes
We can do 60/52 which is
1.538=time to pick one apple
Then we can multiply that by 45 which is
69.21
