Answer:
10
Step-by-step explanation:
The volume of a cube is equal to its (side length)^3
so s^3 = 1000
![s=\sqrt[3]{1000} =10](https://tex.z-dn.net/?f=s%3D%5Csqrt%5B3%5D%7B1000%7D%20%3D10)
Answer:
3/2 mph
Step-by-step explanation:
= 
cross-multiply: 8r = 12
r = 12/8 or 1.5 mph
C, since the radius is 10 multiply by 2 and 100 x 3.14 is 314
Answer:
3.5 or 3 1/2 feet of the shelf
Step-by-step explanation:
Answer: The top of the Crane is 31 feet above the ground.
Step-by-step explanation:
When it is fully extended, the crane arm forms a 30 degree angle with a line parallel to the ground. This means that a right angle triangle is formed. The length of the Crane's arm represents the hypotenuse. The horizontal distance represents the adjacent side of the right angle triangle. The distance, h of the top of the Crane from the ground represents the opposite side of the right angle triangle.
To determine h, we would apply
the Sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 30 = h/62
h = 62Sin30
h = 62 × 0.5
h = 31 feet
