The lighting for a billboard is provided by solar energy. If 6 energy panels generate 10 watts of power, how many panels are needed to provide 550 watts of power?

6/10 = x/550

Cross multiply and solve for x.

To find out how many panels are needed to provide 550 watts of power, we need to determine the ratio of power generated per panel.

Given that 6 energy panels generate 10 watts of power, we can calculate the power generated per panel by dividing the total power by the number of panels:
10 watts / 6 panels = 1.667 watts per panel.

Now, to find out how many panels are needed to provide 550 watts of power, we divide the desired power by the power generated per panel:
550 watts / 1.667 watts per panel = 330.033 panels.

Since we cannot have a fraction of a panel, we need to round up to the nearest whole number. Hence, we would need 331 panels to provide 550 watts of power.
