Answer:
Part a: janice
part b: difference of 3 dollars in hourly pay
Step-by-step explanation:
Divide the amount each person was paid by the hours they worked to find their hourly pay
48 divided by 4 = 12
84 divided by 7 = 12
108 divided by 9 = 12
janice Makes 15 dollars an hour
I suppose we have to find the lengh of the sides.
Area = lenght × width
288 = (3x) × (2x+10)
288 = 3x (2x+10)
288 = 6x + 30x
288 = 36x
288/36 = x
8 = x
therefore the sides are
3x = 3×8 = 24 inches
2x+10 = 2×8 + 10 = 16 +10 = 26 inches
Answer:
As base and height are becoming double the new area is 4 times the original area. When the length of the sides of a triangle double, the area becomes quadruple.
