As the angles are complementary sin A = cos B and sin B = cos A
so sin A + sin B = 0.55 + 0.83 = 1.38
Answer:
3 inches up per foot across
Step-by-step explanation:
rate of change = difference of y / difference of x
R = (18 - 12) / ( 6-4) = 6 / 2 = 3 inch / foot
Answer:
h = 417.81 meters
The altitude of the plane is 417.81 meters
Step-by-step explanation:
given;
The initial height of the girl h0 = 400 m
Horizontal distance from the airport d = 40 m
Angle of elevation of the plane ∅= 24°
The altitude of the plane when the picture was taken is equal to initial height of the girl plus the elevation height.
h = he + h0
And he (elevation height) can be derived as;
he = dtan∅
he = 40tan24°
Substituting into the equation;
h = 40tan24° + 400
h = 417.81 meters
The altitude of the plane is 417.81 meters
You can either scale down so you can get to 48 hours or just multiply from 20 to 48 and I'll explain both ways.
Scaling down:
You can find how many hours it takes to get to 1 gallon in the bucket by dividing
20÷5=4; It takes 4 hours to fill it up to one gallon.
You can now divide 48 by 4 to see how many gallons it'll take up to 48 hours.
48÷4=12
Quicker:
Divide 48 by 20;
48÷20=2.4
Now multiply since it filled it up to 5 gallons.
2.4×5=12
It'll fill 12 gallons in 48 hours.
