Answer:</h3>
B. 1 : 26
Step-by-step explanation:
Let the volume of large cone, the volume of water and the volume of air in the cone be V,
Vw and Va.
Since the cone of water is similar to the large cone and we know its height is x3 smaller,
Vw = (1/3)^3 * V = V/27
Also, Va = V - Vw
= V - V/27 = 26/27 V
Hence, Vw : Va
1 : 26
Negative 1 over 11
negative 1 over 30

-1/6*-1/5 = 1/30
square meter is the SI unit of area.
The correct answer would be Choice B: 4 square units.
When the scale factor is 1/5, that means the lengths of the sides are 1/5 of the original size. So instead of having a base of 20 and height of 10, the new triangle has a base of 4 and a height of 2.
The area of the triangle is: (4 x 2) / 2 = 4
Answer:
54.5°
Step-by-step explanation:
You know that in a right triangle, the sine of an angle is given by ...
Sin = Opposite/Hypotenuse
sin(D) = EF/ED = 57/70
The inverse sine function is used to find the angle:
∠D = arcsin(57/70)
∠D ≈ 54.5°
