Answer:
4.4 hours
Step-by-step explanation:
Let the number of hours = x
Ida needs to hire a singer for her wedding.
For Singer A
Singer A is offering his services for an initial $65 in addition to $13.15 per hour.
65 + 13.15x
Singer B
Singer B is offering her services for an initial $73 in addition to $11.35 per hour.
73 + 11.35x
We equate both singers together
Singer A = Singer B
65 + 13.15x = 73 + 11.35x
We collect like terms
13.15x - 11.35x = 73 - 65
1.8x = 8
x = 8/1.8
x = 4.4444444444 hours
Approximately = 4.4 hours
The two singers will charge the same amount of money after 4.4 hours
2/11 is the answer.. Also don't put college level education if it definitely isn't.
Answer: 125lb < M < 155 lb
Step-by-step explanation:
The mean mass is 140 lb, and the deviation must be less than 15 pounds (exactly 15 is not accepted).
Then (140lb + 15lb) is not alowed, and (140lb - 15lb) is not alowed.
Then we can define M = mass.
We have the two equations:
M < 140lb + 15lb
M < 155lb
And
M > (140lb - 15lb)
M > 125lb
If we write these two relations togheter, we get:
125lb < M < 155 lb
