devlian [24]
The answer is c. 16.70% This is based on the posts I've read online regarding this problem. No solution was given.

These are the amounts you have to consider:
List price of new car - 21,450
Sales tax rate: 6.88% - 21,450 x 6.88% = 1,475.76
vehicle registration fee - 1,089
documentation fee - 124
loan term - 3 years, paid monthly. so, 36 months
interest rate - 12.28% compounded monthly. 
2004 Dodge Neon value - 6,591
trade in value - 6,591 x 80% =  5,272.80

No mention of down payment so the possible amount to be financed is: 24,138.76
The value of the traded car is only considered after the financing has been paid off.

Brian made a tasty burger . the diameter of the Burger was 5cm. what is the radius of the circle?
4vir4ik [10]

19.625cm squared because you have to divide the diameter by 2 to get the radius.

Area of circle = pi times radius times radius

= 3.14 times 2.5 times 2.5

= 19.625cm squared

How to find the slope with only the x and y intercepts?
yuradex [85]
If we have the equation of a line: y=ax+b
How to find a if with only the x<span>-intercepts (called m)</span> and y-intercepts (called n)
+ First we have y=0 and x=m or 0=a*m+b or b= -a*m
+ Then we have x=0, y=n or n=a*0+b or b=n
And if m≠0 we have a= -n/m
and if m=0 this line has no slope

Angles C and E are supplementary. The M&gt;C = 112 and M&gt;E = (3x + 50) Solve for X.
maxonik [38]

Answer:

The value of x is 6

Step-by-step explanation:

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

so

In this problem

m∠C+m∠E=180°

we have

m∠C=112°

m∠E=(3x+50)°

substitute and solve for x

112°+(3x+50)°=180°

3x+162=180

3x=180-162

3x=18

x=6
