Of 734 students, 442 are taking mathematics. What angle (in degrees) of a circle would show the percent of students taking mathe

Anestetic [448]

We need to find the angle (rounded to the nearest whole degree) of a circle that would represent the percent of students taking mathematics.

Since a complete turn around the circle has 360º, we have the following proportion:

<em>Number of students Angle</em>

734 360º

442 x

Then, cross multiplying the above values, we obtain:

$\begin{gathered} 734x=442\cdot360\degree \\ \\ x=\frac{442\cdot360\degree}{734} \\ \\ x\cong217\degree \end{gathered}$

<em>Answer</em>: 217º

Ron is planning to buy a condo that costs $85,000. At which mortgage lender will Ron get better deal? How much less will Ron pay

Andreyy89

Mortgage Lender A:

$85000 - 4500 = 80500$

$80500\times .03 = 2415$

$80500 + 2915 = 82915$

$85000 - 7500 = 77500$

$77500 \times.06 = 4650$

$77500 + 4650 = 82150$

Lender B is the cheapest by $745!!!
