1 answer:
Answer:
Step-by-step explanation:
Total bill - the tax = cost of 3CD's
Our total bill is $35.40, the tax is $2.70, therefore,
35.40 - 2.70 = cost of 3 CD's so
3 CD's = $32.70
Divide that by 3 to get the cost per CD:
32.7 / 3 = $ 10.90 per CD

Answer:
The right answer is 80in^2
Step-by-step explanation:
T = k * sqrt(d), where k is a real constant.
When d = 6, T = 5.
k = T / sqrt(d) = 5 / sqrt6.
Therefore when d = 3, T = (5 / sqrt6) * sqrt3 = 3.53.
