the length of a rectanglr exceeds its width by 5 inches, and the area is 84 square inches. what are the length and width of a a

irga5000 [103]

The area is the product of length and width, which is to say that the length and width are factors of the area.

Assuming the dimensions are integers, you want factors of 84 that differ by 5.

... 84 = 1×84 = 2×42 = 3×28 = 4×21 = 6×14 = 7×12

The last of these pairs differ by 5, so ...

the length is 12 inches
the width is 7 inches.

A student's course grade is based on one midterm that counts as % of his final grade, one class project that counts as % of

Andrei [34K]

Answer:

The overall score is 75.6

Letter grade is C

Step-by-step explanation:

The question has missing details (See comment section for complete question).

From the complete question, we have:

<u>Proportion:</u>

$Midterm = 15\%$

$Project = 25\%$

$Assignment = 40\%$

$Exam = 20\%$

Scores

$Midterm = 66$

$Project = 90$

$Assignment = 75$

$Exam = 66$

Solving (a): The overall score

To do this, we simply calculate the mean of the given data.

The mean is calculated by multiplying each proportion by the scores..

So, we have:

$Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66$

$Overall = 9.9 + 22.5 + 30 + 13.2$

$Overall = 75.6$

Solving (b): The letter grade

From the question, we have:

$A: Mean \ge 90$

$B: 80 \le Mean < 90$

$C: 70 \le Mean < 80$

The overall score falls in the following category:

$C: 70 \le Mean < 80$

Because:

$70 \le 75.6 < 80$

<em>Hence, the letter grade is C</em>
