Answer:
<u><em></em></u>
- <u><em>Option A. 94</em></u>
Explanation:
The column of digits to the left (before the vertical line) contains the largest place-value digits.
Here is how you read the values:
- Third row: 80, 80, 81, 82, 85, 88, 89
Thus, the highest score received is 94.
<h3>Option C</h3><h3>The average rate of the reaction over the entire course of the reaction is:

</h3>
<em><u>Solution:</u></em>
Average rate is the ratio of concentration change to the time taken for the change

The concentration of the reactants changes 1.8 M to 0.6 M
here, the time interval given is 0 to 580 sec
Therefore,

Thus option C is correct
3^2 + 4^2 = c^2
sqrt(9) + sqrt(16) = c^2
Sqrt(25) = c^2
C = 5
First you have to plug in your information into the formula- y=mx+b
So we know the y is 2, the slope (m) is 1/2, the x is 2 and we don't know the b. Do plug it in the formula and solve... you should get 2=1/2(2)+b you will end up with 1=b and the final answer is y=1/2x+1
