<h3>Answer:</h3>
C. The playable area has a width of 9 inches and a height of 6 inches.
<h3>Explanation:</h3>
There are a number of ways you can get there.
1. Check the answers to see which have the right area and aspect ratio.
- A: area = 24 in² — does not match 54 in²
- B: area = 54 in², aspect ratio 6:9 = 2:3 — does not match 3:2 aspect ratio
- C: area = 54 in², aspect ratio 9:6 = 3:2 — <em>matches problem statement</em>
- D: area = 121.5 in² — does not match 54 in²
2. If the screen were 3:2 (inches), its area would be 6 in². The area of 54 in² is 9 times that value, so the actual screen dimensions are √9 = 3 times 3:2. That is, they are width:height = 9:6 inches — matches selection C.
3. You can write equations for width and height and solve.
Substituting w=3/2·h into the second equation gives
... (3/2)h·h = 54
... h² = 36 . . . . . multiply by 2/3
... h = √36 = 6 . . . . square root, result in inches . . . . matches selection C
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! :)
