One sixth of 36 hundreths is 6 thousands which is 3.994 less than four meaning that answer is false.
You’re very close! This is a triangular prism which means that the triangle portion has a unique formula. In order to find area of the triangle you do (base x height) and then divided by 2. In this case, base=6 and height=5 so 6x5=30 and 30 divided by 2 is 15. Then multiply by the length which is 10. The final answer is 150cm cubed.
Given that the ball has a thickness of 1 cm and the radius at the outside is 5 cm, thus the radius from inside is 5 - 1 = 4cm.
The <span>approximate volume of rubber used to make the ball is given by the volume of the ball at the outside surface minus the volume of the ball at the inside surface.

Anything to a negative power becomes the inverse with the coefficient to a positive power.
For example, 3^-1 becomes 1/3^1 or just 1/3.
3^-2 would be 1/3^2 or 1/9.
Subtract 5x from both sides
0=-30x
Divide both sides by -30
0=x
Final answer: x=0
Hope this helps!
