Answer:
A. 3:7
Step-by-step explanation:
The volume of the smaller cube is 216 m³.
The volume of the larger cube is 2744 m³
Let the similarity ratio be 
The volume of these two cubes are in the ratio:

This implies that:

We take the cube root of both sides to obtain:
![\frac{l}{L} =\sqrt[3]{\frac{216}{2744}}](https://tex.z-dn.net/?f=%5Cfrac%7Bl%7D%7BL%7D%20%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B216%7D%7B2744%7D%7D)

This simplifies to:

Therefore the ratio is 3:7

Answer:
9.73 cm to 2 DP
Step-by-step explanation:
Total of the lengths involved = 7*9.4 + 5*10.2
= 116.8 cm
So the mean of the 12 fingers
= 116.8/12
= 9.73 cm to 2 DP.
Check the picture below, that one in the picture is just an example of the correspondence of sine and cosine in a right-triangle, in this case, we're in the 0° < x < 90°, so in the I Quadrant, and thus we have a right-triangle.
to make it short, sin(90° - 19°) = cos(19°), or that is sin(71°), thus x = 71.
Answer:
y = -1/3x + 4
Step-by-step explanation:
Perpendicular line are opposite and reciprocal.
So I flip 3x to 1/3 and change both signs. negative to positive and positive to negative.
