Answer:
a. 208.5 ft.
b. 144.9 ft.
Both correct to the nearest tenth.
Step-by-step explanation:
(a) sin 46 = 150 / h where h is the length of the wire.
h = 150/ sin 46
= 208.5 ft.
(b) tan 46 = 150 / x where x is the distance required.
x = 150 / tan 46
x = 144.9 ft.

Answer: Part a) 375 pounds, Part b) 8 words
Step-by-step explanation:
a)
<u />
Since n represents the number of words there are, we can plug in 20 for n into the equation to get:
C = 15*20 + 75 pounds
C = 300 + 75 pounds
C = 375 pounds
b)
Since C represents the cost of the advert, we can plug in 195 for C into the equation to get:
195 = 15n + 75
Subtract 75 from both sides:
120 = 15n
Divide both sides by 15:
n = 8 words
