Answer:
Therefore the height of the tower is 116.75 m.
Step-by-step explanation:
Given that a pole that is 2.6 m tall casts a shadow that is 1.03 m long.
Here the height of a object directly proportional to the shadow. It means
Height of the object ∝ shadow
Height of the object= k.shadow
[k is the proportional constant.]
[Height of object is denoted by h and shadow is denoted by s]
Then,
[h₁ is the height of the pole and s₁is the length of the shadow]
Again for the tower
[h₂ is the height of the tower and s₂ is the length of the shadow]
Therefore,
............(1)
Given 
,
and 
Putting the value of 
and 
equation (1)
[cross multiplication]
Therefore the height of the tower is 116.75 m.
Answer:
C 180-123
Step-by-step explanation:
This is because 180 is what triangles always equal and if one angle is 128 then the rest will be answered from this equation
Answer:
81 1-inch cubes
Step-by-step explanation:
Cube root of 729 is 9
9 x 9 = 81
Further explanation:
A cube has 3 measures (there are all the same) to solve for the volume. If the volume is 729, and it is a cube, you would solve for the cube root, because all the numbers are the same. Then, we would get 9. Now, since a cube is made up of faces, and each one is a square, we do 9 x 9 to get the area, which is the answer, because 1-inch cubes are literally just units.
Answer:
B) 243 km^3
Step-by-step explanation:
The formula for volume is Length x width x height, so we must find those values. By looking at the shape, the length is 9 km, width is 9 km, and height is 3 km, and after substituting these values in the equation, we get 9 km x 9 km x 3 km. When multiplied, it equals to 243 km^3, so the answer for the volume of the solid is B) 243 km^3.
Hope this helped somewhat! :P
