Answer:
A=920 ft.
Step-by-step explanation:
Using the formulas
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=8·20+17·20+15·20+1
2·﹣84+2·(8·17)2+2·(8·15)2﹣174+2·(17·15)2﹣154=920
Answer:
Meiling's Dog
Step-by-step explanation:
Determine how much each dog eats per day by dividing the amount in pound by the number of days given.
Charlotte's Dog = 10.5/12 = 0.875pounds per day
Meilings Dog = 15/16 = 0.9375pounds per day
Amelia's Dog = 4/6 = 0.67pounds per day
Zahra's Dog = 6/8 = 0.75pounds per day
Therefore,
Meilings Dog with 0.9375 pounds per day is the answer
Ideally, the smaller the sample population, the more accurate is the sampling result, but it will take longer time if the number of samples is huge.
The answer to the above question is ideally 20 light bulbs per sampling.
