Suppose a man's scalp hair grows at a rate of 0.35mm per day. What is this growth rate in feet per century?

1 answer:

5 0

To start, we need to determine the growth rate in millimeters per century.
Given that a century comprises one hundred days, we simply multiply 0.35 by 100. Shifting the decimal two places to the right gives us a result of 35 mm each century. We can convert 35 mm to feet using a conversion calculator, yielding 0.1 (rounded to the nearest tenth).
Thus, the growth rate equates to 0.1 feet per century. I hope this clarifies your question!

AnnZ [9099]

Answer:

13%

Detailed breakdown:

Information provided:

MP = 2080
Discount = d%
VAT = (d-2)%
Cost = 1997.84

Applying the discount:

2080 - d% = 2080*(1 - 0.01d)

Including VAT:

2080*(1 - 0.01d) + (d - 2)%
2080*(1 - 0.01d) * (1 + (d -2)/100)
2080*(1 - 0.01d) * (0.98 + 0.01d) = 1997.84
(1 - 0.01d)(0.98 + 0.01d) = 1997.84/2080
0.98 + 0.01d - 0.0098d - 0.0001d² = 0.9605
- 0.0001d² + 0.0002d + 0.98- 0.9605 = 0
0.0001d²- 0.0002d - 0.0195 = 0
d² - 2d + 195 = 0

Solving this quadratic equation yields:

d = 15

Therefore

VAT rate = 15 - 2 = 13%

lawyer [9240]

In the first month, she made a payment of $1451

In the second month, she paid one-third of that, which amounts to:
1451/3 = 483.66

For the third month, she pays one-third of 483.66 as indicated, meaning she takes one-third of the prior month's payment.

483.66/3 = 161.22

In the fourth month, her payment was

161.22/3 = 53.74

Altogether, her total payments amounted to:
