14 = 7x2
7+3= 10
2+3=5
10+5=15
15/2= 7.5
The total of it seems to be 60 since there is nothing else before this question .

-18 + 19½ = 1½?
37½
Step-by-step explanation:
(18 × 2) + 1½ = 37½
Answer:
B, C and D all appear to be repeating decimals
Step-by-step explanation:
SOH CAH TOA tells you the sine function of an angle gives the ratio of opposite side to the hypotenuse of the right triangle.
Sin = Opposite/Hypotenuse
In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).
sin(30°) = height/(3000 m)
Multiplying by 3000 m, we get
height = (3000 m)*sin(30°) = 1500 m
The height of the plane at that instant is ...
1500 m
