Step-by-step explanation:
Suggest you use some punctuation here: "The h<span>eight of window is 0.6 feet less than 2.5 times it width. The height of window is 4.9 feet. Find the width of the window."
height of window = 4.9 feet = 2.5(width) - 0.6 feet.
simplify this equation by adding 0.6 feet to both sides of the equation:
4.9 feet + 0.6 feet = 2.5 (width); find width:
5.5 feet = 2.5 (width)
Dividing both sides of this equation by 2.5 will result in an equation for the width of the window, in feet.</span>

Answer:
Option (4).
Step-by-step explanation:
Outer diameter of the hollow metallic ball = 10 centimeters
Outer radius of this ball =
= 5 cm
Volume of the outer ball
= ![\frac{4}{3}\pi (r)^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%28r%29%5E3)
= ![\frac{4}{3}\pi (5)^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%285%29%5E3)
Inner radius of the hollow metallic ball = (5 - 1) = 4 cm
Volume of the inner hollow ball
= ![\frac{4}{3}\pi (4)^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%284%29%5E3)
Volume of the metal used in the metallic ball = ![V_{1}-V_{2}](https://tex.z-dn.net/?f=V_%7B1%7D-V_%7B2%7D)
= ![\frac{4}{3}\pi (5)^3-\frac{4}{3}\pi (4)^{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%285%29%5E3-%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%284%29%5E%7B3%7D)
= ![\frac{4}{3}\pi [(5)^3-(4)^3]](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%5B%285%29%5E3-%284%29%5E3%5D)
Therefore, expression given in option (4) will be used to measure the volume of the hollow metallic ball.
