Hello,
I suppose N in on the same line as MH
Angles are thus supplementaries
180-143=37°
Answer B
The glee club could have 6 members so the 48 classical CDs would be divided into 8 and the 42 show tunes could be divided into 7
Y=mx+b
ok, so notice that b is constant, doesn't change, when x=0, then y=b
that is the starting value
it is stated that he has 41 at the begining so
y=mx+41
alright
so we are also given
when x=5, y=66
so find m
66=5m+41
miinus 41 from both sides
25=5m
divide both sides by 5
5=m
the equation is
y=5x+41
Answer:
c
Step-by-step explanation:
Using a spectrometer, a sample was analyzed to have a percent transmittance of 85%. This means that the remainder of the light was absorbed by the sample given in the question.
Now, from the 100% light that has been incident on the sample, if 85% was transmitted, then the percentage of light was actually absorbed by the sample can be found out as:
percentage of light was actually absorbed by the sample=100% - (percentage of light transmitted by the sample)
Therefore, percentage of light was actually absorbed by the sample=100%-85%=15%
Thus, 15% light was actually absorbed by the sample.
