Answer:
C. $8.75
Step-by-step explanation:
52 weeks in a year times that by 40 to get how many hours she worked in the entire year
She worked for 2080 hours last year
Now divide 18,200 by 2080 to get how much she makes an hour
Convert them all to 10 in the denominator.
4/10, 5/10, 1/10, 2/10, 4/10
Now which ones are greater than 2/5?
5/10 only.
I think -1,2 or something else I’m not sureee sorry hope it’s gets answered
I=10^(1-0.13x)
When I=4.2, then:
4.2=10^(1-0.13x)
ln 4.2=ln(10^(1-0.13x))
ln 4.2=(1-0.13x)ln (10)
1-0.13x=ln 4.2 / ln 10
-0.13 x=(ln 4.2 /ln 10)-1
x=[(ln 4.2/ ln 10)-1] /(-0.13)
x=-0.37675/(-0.13)
x=2.898...≈2.9
Answer: The depth of water at which most aquatic plansts recieve the requred light would be 2.9 m
You will get a negative answer which is -124.35
