Answer:
Angle 1 = 10 degree, Angle 2 = 170 degree
Step-by-step explanation:
m1 + m2 = 180 degree
(x - 24) + 5x = 180
6x - 24 = 180
6x = 204
x = 34
m1 = x - 24 = 34 -24 = 10 degree
m2 = 5x = 5(34) = 170 degree
Answer:
Step-by-step explanation:
- Original expression:
- Exponents: 5 and 7
- 5 × 7 = 35
- So, and are the same.
I hope this helps!
Answer:
Hence, the limit of the expression is:
0.1667 (i.e. option b is true)
Step-by-step explanation:
We are asked to estimate the limit of the expression:
We know that:
Hence, we could represent it as:
Since we cancel out the similar terms in the numerator as well as in the denominator.
Hence, the limit of the expression is:
0.1667
Answer:
Abundance of isotope 79Br=51% and abundance of 81Br=49%
Step-by-step explanation:
We are given that
Mass of 79Br=78.9183 u
Mass of 81Br=80.9163 u
Average atomic mass of bromine=79.90 u
We have to find the relative abundance of the two bromine isotopes.
Let x be the abundance of 79Br
Then , abundance of 81Br isotopes=1-x
Average atomic mass=Mass of isotope(abundance of isotope)+Mass of other isotope(abundance of other isotope)
Using the formula
Percentage of isotope with abundance 0.51=%
Abundance of other isotope=1-0.51=0.49
Percentage of other isotope with abundance 0.49=%
Y2-Y1 or X2-X1 is the formula
9-4/1-0
It would be undefined
