Ln x=5-2
ln x=3
ln x is base e log x
so,
x=e^(3)
x=20.0855369232
5:3 x 6:2 can also be written as a fraction
5/3 x 6/2
Multiply across
30/6
Simplify
5/1
Rewrite
5:1 is your answer, or if your teacher does not want it simplified, 30:6
Hope I helped! :)
Answer:
<R=23°
Step-by-step explanation:
The sum of angles in a triangle is 180°
So, <R + <S + <T = 180°
<R+90°+67°=180°
<R+157°=180°
<R=23°
Mixing the two concentrations would give a new concentration which is in between 50 - 60% .
D. 63% cannot be obtained
Rotational symmetry = 360 / # sides
rotational symmetry = 360 / 9
rotational symmetry = 40 degrees
