TO FIND: the formulas that describes how a student's raw score, r, depends on the number of correct answers he or she provided, c.

SOLUTION:

Total number of incorrect questions =40-\text{c}

Total marks deducted due to incorrect question =(40-\text{c})\times0.5=20-0.5\text{c}

Total correct questions =\text{c}

Total marks scored =6\text{c}

Total raw marks \text{r}=\text{total marks gained}-\text{total marks deducted}

                           \text{r}=6\text{c}-(20-0.5\text{c})

                           \text{r}=5.5\text{c}-20

ormulas that describes how a student's raw score, r, depends on the number of correct answers he or she provided, c is  \text{r}=5.5\text{c}-20

20 POINTS AND BRAINLIEST ANSWER
soldi70 [24.7K]
Let's look at our equation,
<span>p÷7

We must look at all our options before selecting one of them.

Can the answer be A?

</span><span>Jayna does not know how many pages she needs to read. She knows she has already read for 7 days.
</span><span>
No that would not work,
We would have subtraction. It would look like this.
p-7.

How about B?

</span><span>Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span><span>
That would actually work. This is how our equation would look. 
p</span>÷7. 
<span>It matches the expression.

Before we make that our final answer, we should check everything else.

Here is C
</span><span>C.
Jayna does not know how many days she has to finish reading. She knows she has to read 7 more pages.
</span>
That would not work.

How about D?

<span>D.
Jayna does not know how many pages she has already read. She knows she has to read 7 more.
</span>
D is also incorrect. It would not work at all.

That means our final answer is:

<span>B.
Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span>
I hope that helped! :)

A hiker is descending 152 m every 8 minutes what will be hikers change in elevation in half an hour.write as an integer
victus00 [196]

Solving this problem is just pretty straight forward. All we have to do is to use the concept of ratio and proportion.

First, let us say that the change in elevation in half an hour (30 minutes) takes the value of variable x.

From the given, we know that the ratio of height and time is:

152 m : 8 minutes

And the next ratio is:

x : 30 minutes

To solve for the value of x, we equate the two:

152 m : 8 minutes = x : 30 minutes

We know that the symbol of ratio which is “:” also means division, therefore:

152 m / 8 minutes = x / 30 minutes

x = 152 m * 30 minutes / 8 minutes

x = 570 m

 

Therefore the change in elevation after half an hour is 570 meters.
