Answer:
32 ft
Step-by-step explanation:
The length of the larger rectangle is double that of the smaller one. If we assume the rectangles are similar, the perimeter will be double as well:
2·(16 ft) = 32 feet . . . . perimeter of larger rectangle
__
The width of the larger one is 2·1.8 ft = 3.6 ft.
Simplified: 3x+7y+(-2y)+9
Coefficient of y: 5
Constant: 3 and 6
P(heads) = 1 - 0.4 = 0.6
The answer is 0.26 to 2 d.p.
2. always
Percents tell us how many parts a certain thing has out of a total of 100 parts; thus, the denominator is always 100.
