The first angle is 42 degrees
the second angle is 84 degrees
the third angle is 54 degrees
Percentage abundance describes how many candies (object) are present within every 100 particles.
Relative abundance, however, is used to describe the abundance of a certain isotope of the object (candies in this case) within the given sample of the same object.
Answer:
Left-hand side: .
Right-hand side: .
Step-by-step explanation:
Apply the logarithm power rule: for all .
This property is not only true for logarithm to the base , but for other bases, as well.
Take the logarithm (to the base ) of the left-hand side of this equation:
.
For the right-hand side of this equation, consider the logarithm quotient rule:
for all and .
Indeed, on the right-hand side of this equation, and . Therefore:
.
This expression could be further simplified. Notice that is equivalent to for all . (Think about how whereas .)
Therefore, would be equivalent to . Apply the logarithm power rule to show that .
.
Indeed, the left-hand side of this equation matches the right-hand side.
First, you have to know the formula of finding the area of a triangle. That is bh1/2. You multiple the base and height together and multiply it by 1/2 or divide by 2. You put in the info they gave you in the formula, after that you get 105/8. That is obviously not one of the choices and it is an improper fraction. The way to make it into a whole fraction is to do 105 divided by 8. Then, you get 13, which is the second answer. Finally, the area of the triangle is 13 1/8 squared mm.
