5.5 : 30.80 = 7 : x
x = 7 * 30.80 / 5.5 = $39.20
Answer: $39.20
I believe she will have to work 12 hours!
Good luck!
Ok, first you have to know that 0.25 is one fourth. Finding one fourth of 60 is the first step. 1/4 of 60 is 15. Now, add 3 to 15, and you have your answer! The answer is 18 pounds.
Answer:
95.44%
Step-by-step explanation:
Mean rate (μ) = 160 euros
Standard deviation (σ) = 8 euros
For any given rate, X, the z-score is:

For X = 144 euros:

For X= 176 euros

In a standard distribution, a z-score of -2 corresponds to the 2.28th percentile, while a z-score of 2 corresponds to the 97.72th percentile.
Therefore, the percentage of hotels with rates between 144 and 176 euros is:

Answer:
|x-1|=5
Step-by-step explanation:
From the diagram you can see that the solutions of the equation are
and 
1. Find the midpoint between -4 and 6:
1/2(-4+6)=1
2. Find the distance between points x=1 and x=6 (or between x=1 and x=-4):
d=6-1=5
3. Writhe an absolute value equation (the distanse from endpoints
and
to the midpoint x=1 is equal 5):
|x-1|=5
