In this question, you have given the table length (7. 1/2 feet) and the table maximal area (46 7/8 square feet). The question is about whether Julia buys a table greater than 6ft wide, in other words, we need to determine the table maximum width. The equation from this problem can be written as:
Table max area = 46 7/8 ft
Table length= 7 1/2 ft
Using area formula, the calculation for maximal width would be:
length * max width = max area
7 1/2 ft * max width = 46 7/8 ft
max width = 46.875/ 7.5 = 6.25ft
The answer to this question would be yes, she can buy a table with more than 6 ft width. But it should not more than 6.25ft width
<u>Answer:</u>
96
<u>Step-by-step explanation:</u>
Let's assume that the marks needed in the next exam is 
. Then if the average becomes 90,
Now we can simply solve for :
⇒ 
⇒ 
[Multiplying both sides by 4]
⇒ 
[Subtracting 264 from both sides]
⇒ 
Therefore, you need to score 96 in your next exam to have an average of 90 on the four exams.
Answer:
y = $15.5x
Step-by-step explanation:
Given that
Tim earns $31 after 2 hours
$46.5 earns after 3 hours,
And, $62 earns after four hours
So first determine the each hour earnings i.e.
= $31 ÷ 2
= $15.5
In two hours it would be $31 and so on
So here the equation would be
y = $15.5x
Here
y = money amount
x = number of hours
