It would be 7/10 because since 10/10 is the Earth, and 3/10 is water, 10-3 is 7.
<u>LCD is least common denominator, also called least common multiple LCM</u>
5/6, 2/9 LCD is 18
1/12, 3/8 LCD is 24
5/9, 2/15 LCD is 45
18, 24, and 45 are the least common multiples of the denominators for their own pair.

No, you cant add things with multiple variables:)
Well,
8 + 6q + q
We could be lazy and not simplify this. Thus, we would say:
"Eight plus 6 times a number q plus q."
Or, we could be smart, collect like terms, and say:
"Eight plus 7 times a number q."
Answer:
The taller building is the second building which is the apartment building on the left with an height of 58.4m
Step-by-step explanation:
This is a Trigonometric question. We solve this using the Tangent formula
tan θ = Opposite side/Adjacent side
We are given 2 buildings
Building 1
tan θ = Opposite side/Adjacent side
θ = Angle of Elevation = 40°
Distance from the base of the building = Adjacent = 56m
Height of the building = Opposite side = unknown
tan 40 = 0pposite/56m
Opposite = tan 40 × 56m
Opposite = 46.989579346m
Approximately = 47m
Height of Building 1 = 47m
Building 2
tan θ = Opposite side/Adjacent side
θ = Angle of Elevation = 50°
Distance from the base of the building = Adjacent = 49m
Height of the building = Opposite side = unknown
tan 50 = 0pposite/49m
Opposite = tan 50 × 49m
Opposite = 58.395926037m
Approximately = 58.4m
Height of Building 2 = 58.4m
The taller building is the second building which is the apartment building on the left with an height of 58.4m
