Answer:
She could spend $18 on each for the 4 friends
Step-by-step explanation:
100-28= 72
72/4=18
16 times 4 equals to 64. 64 is simply 4 sets of 16 added together.
Other factors of 64 include, 1,2,4,8,16,32, and 64.
Answer:
A)14 Units is the answer for this question
but check it
Answer:
So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.
Absorbance is the inverse of transmittance so,
A = 1/T
Beer's law (sometimes called the Beer-Lambert law) states that the absorbance is proportional to the path length, b, through the sample and the concentration of the absorbing species, c:
A ∝ b · c
As Transmittance, 
% Transmittance, 
Absorbance,
Hence,
is the algebraic relation between absorbance and transmittance.
Expand the brackets .You will have to multiply it.
6x2 +10x-3x-5
Final answer will be
6x2+7x-5
x2 means (x square)
