Answer:
<em>2.8 + 27.44k</em>
Step-by-step explanation:
<u>Algebraic Simplification</u>
The rules of algebra can be applied in some situations to make expressions simplified or expanded, according to the specific needs of each problem.
We are given the expression:
(1 + 9.8k)(2.8)
It's a sum and a product. We cannot add the independent term with the variable term, so we can only multiply the factor and the contents of the parentheses as follows:
(2.8)1 + (2.8)9.8k
Operating:
2.8 + 27.44k
Answer:
Kerri's speed = 50 mile per hour. Therefore option (D) is true.
Step-by-step explanation:
Given the distance-time graph
It is clear from the distance-time graph that:
- at Time = 1 hour, Distance = 50 miles
- at Time = 2 hours, Distance = 100 miles
so the two points on the distance-time graph is:
Finding the slope between the points to determine the speed.
Please note that the slope between the points represents the speed or rate of change.
Speed = Rate of change = y₂-y₁ / x₂-x₁
= 100 - 50 / 2-1
= 50 / 1
= 50 miles per hour
Thus, Kerri's speed = 50 mile per hour. Therefore option (D) is true.
The question is an illustration of Excel formulas, and the formula to enter in cell C2 is: =(B2/600)
<h3>How to determine the % marks that the students obtained?</h3>
To enter a formula in Microsoft Office Excel, we make use of the following syntax:
= (Formula)
From the question, the total score is 600.
So, the formula to enter in cell C2 is:
=(B2/600)
Next, drag the content of cell B2 through cell C12.
This is to ensure that all cells C2 to C12 have the appropriate formula.
Lastly, following the highlighted steps to show the result as percentage
- Go to the home tab
- Select the number group
- Click the Percent Style button
- Increase the number of decimal places, as desired.
