C? I'm not sure. It seems like the most reasonable answer.
Complete question :
The Daily Info charges a fee $650 of plus $80 per week to run an ad. The People's Paper charges $145 per week. Write an inequality to represent the number of weeks an ad must run for the total cost at the Daily Info to be less expensive than the cost at the People's Paper. Let w be the number of weeks the ad runs in the paper
Answer:
650 + 80w < 145w
Step-by-step explanation:
Given that :
Number of weeks ad will run = w
Daily Info total cost :
650 + 80w
The People's Paper total cost:
145w
Number of weeks ad should run For cost at daily info to be less expensive than peoples choice';
Daily Info total cost < people's choice
650 + 80w < 145w
650 < 145w - 80w
650 < 65w
650/65 < 65w / 65
10 < w
w > 10
Answer:
The probability of exercise in cruise ships = 73
Step-by-step explanation:
Let A be the probability of rock climbing
Let B be the probability of ice skating
Let C be the probability of fitness center
P(A) = 36, P(B) = 44, P(C) = 27
P(A ∩ B) = 14, P(A ∩ C) = 11, P(B ∩ C) = 9
P(A ∩ B ∩ C)=0
By formula,
P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B) − P(A ∩ C) − P(B ∩ C) + P(A ∩ B ∩ C).
Substituting the values in the above formula,
P(A ∪ B ∪ C) = 36 + 44 + 27 - 14 - 11 - 9 + 0
= 107 - 14 - 11 - 9
P(A ∪ B ∪ C) = 73

Answer:
∠U = 60°
∠W = 30°
Step-by-step explanation:
The side length ratios are ...
1 : √3 : 2
so you know this is one of the "special triangles." Its angle measures are 30°, 60°, and 90°. The smallest angle (W) is opposite the shortest side (7).
The angle measures are ...
m∠U = 60°
m∠W = 30°
[the UW measure is correct]

Your calculator can tell you the arctangent of √3 or 1/√3. Be sure to set it to degrees mode.
