It would be 574 over 1000, but it can be simplified to: 287 over 500. So the final answer simplified would be 287/500.
Just count the amount of each letter and write it as a exponent = 3x²y³
Split this figure into 3 shapes: 2 triangles and 1 trapezoid
Area of top triangle = 1/2(7)(2) = 7 square units
Area of bottom triangle = 1/2(3)(7) = 10.5 square units
Area of trapezoid = 1/2(3 + 6)(4) = 18 square units
Area of the polygon = 7 + 10.5 + 18 = 35.5 square units
30 * 1/5 = 6 so 6 have a cell phone
1/2 * 6 = 3 so 3 have a cellphone and social media
195 divide by 2 1/2
195 divide 5/2 (copy dot flip)
195 * 2/5
78 loads of laundry
19.99 divide by 78
.256
.26
he is paying 26 cents for each load
THis will be the coordinates of the point at a turning point on the graph.
Since the second derivative is positive (=1) it will be a minimum value of f(x).
