Answer:
I think the answer is 47
Step-by-step explanation:
4. 6/8, 5. 3 5/8, 6. 7 7/8, 7. 72 months and 2,190 days
Area covered by the solar cells = 269.5 m^2
Area of one cell = 150 cm^2
Convert the area of one cell to m^2 by using the conversion factor 1m^2 = (100cm)^2 => 1 = 1m^2 / 1000 cm^2
=> 150 cm^2 * [1m^2 / 1000 cm^2] = 0.150 m^2
Now finf the number of times that 0.150 is contained in 269.5 by dividing 269.5 by 0.150
269.5 = 0.150 = 1,796.67
Which means that the number of cells is betwee 1796 and 1797.
Linear systems that have infinite solutions have the same slope and they have the same line on the graph
