a. x3 + 4x + 8
b. 76 + 5x
c. (x)1/2 + 5x - 6
d. 500 + (45)1/2x
e. 289y + 6 -76y
f. (37)1x1
g. (9x2)1/2 + 3
h. 89x4 + 3y + 5

Ratio and Proportion

Solve the following questions

1. A lawyer bills her clients $250 per hour of service. If a client's case requires 47 hours to complete, use proportion to calculate how much the client will owe the lawyer (excluding tax).
2. A new virus is released on the internet; the administrator of a department's Local Area Network ( LAN) is given five minutes by a manager to estimate the impact. The administrator samples 12 of the PCs connected to the LAN, and finds that 7 are infected; use proportion to estimate the number of infected PCs if there are a total of 117 PCs connected to the LAN.
3. An administrator of a popular web site is told that a new server can handle 11,000 "hits" (users accessing the site) per second. The web site currently experiences a

1. 11750
2. 68 PCs
3. incomplete info

Answer 2

b,d,e,f

1. 250/1 = x/47
47(250) = x

2. 7/12 = x/117
819/12 = x

3. incomplete question

Answer 3

1. letter b, e, f

1. (250)(47)=x
x=$11,750

2. 12:7=117:x
x=69

3 not completed the given

Answer 4

I would eliminate a and h for exponents larger than 1, c for an exponent which is a fraction d for having a negative component and g because (9x^2)^1/2 = |x|.

The only polynomains of degree one are b,e and f.
