Answer:

A=ε*l*c

A= 2- log₁₀ % T

Step-by-step explanation:

There is a linear relationship between the concentration of a sample and absorbance according to Beer-Lambert Law.

A=ε*l*c

where;

A=absorbance

ε=absorption coefficient

l=path length

c=concentration

Because % transmittance is transmittance value multiplied by 100 then, the equation that will allow us calculate absorbance from % transmittance value will be;

A= 2- log₁₀ % T where T is transmittance.

Answer:

Area of shaded part ABCEF = 66 sq.cm

Step-by-step explanation:

AB = 8cm

CD = 8cm

Let DE = x cm

CE = 3x cm

CD = CE + DE = 8cm

x + 3x = 8

4x = 8

x = 8/4 = 2 cm

DE = 2cm

CE = 3 * 2 = 6 cm

Area of triangle ADE = 1/2 * base * height

= 1/2 * DE * AD

= 1/2 * 2 * 11 = 11 sq. cm

Area of triangle AEF = Area of triangle ADE = 11 sq. cm

Area of Rectangle ABCD = l * b = 8 * 11 = 88 sq.cm

Area of shaded part ABCEF = Area of Rectangle ABCD - (Area of triangle AEF + Area of triangle ADE)

= 88 - ( 11 + 11 ) = 88 -22 = 66 sq.cm

र Solve the equation y + 3 = -y + 9 O y= 1 O y=3 O y=6 O y=9 र

Leto [7]

Answer:

y=3

Step-by-step explanation:

y + 3 = -y + 9

y + y = 9 - 3

2*y = 6

y = 6/2

y = 3
