Answer:
<h2>C. 0.05 +0.1y = 0.12 + 0.06y</h2>
Step-by-step explanation:
According to the problem, both expression are equal because they have the same amount of mercury.
When the problem specifies an initial value, this means that value is not with the variable, because is an initial constant. When the problem specifies a rate, this is a coefficient of the variable, which expresses time (years.)
So, 0.05 parts per billion with a rate of 0.1 means: 0.05 + 0.1y, because the ratio is rising, that means is positive.
Similarly, 0.12 parts per billion with a rate of 0.06 means: 0.12 + 0.06y, because the ratio is also increasing, is positive.
Therefore, the right answer is C.
Answer:
Distributive
Step-by-step explanation:
Ex of Distributive: 2.4 + 2.3 = 2 ( 3 + 4 )
Ex of Commutative: 4 + 3 = 3 + 4
Ex of Associative: 3 + ( 4 + 5 ) = ( 3 + 5 ) + 5
Ex of Identity: 7 x 1 = 7

Answer:
At least 100 degrees
Step-by-step explanation:
Here, we want to make an inequality assertion from the graph drawn by Dr Hilton.
The correct conclusion here is that a person has a fever once his/her temperature is greater than or equal to 100 degrees.
How do we know this from the graph? from the graph, we can see a yellow circular mark placed on 100. This indicates that we are starting our consideration from the point 100 degrees. What we don not know is if our answer is less than, greater than, less than or equal to or greater than or equal to.
The correct answer is however greater than or equal to. Firstly we check the fill of the yellow circular mark. Once it is filled and not left blank, then it indicates an equal to relationship, meaning 100 degrees itself is included in the range.
finally we then consider the direction it faces and from here we can conclude that it is greater than or equal to
