Determine the finance charge on a $6,800 car loan if monthly payments were $158.50 for 48 months.

Answers

Answer:

808

Step-by-step explanation:

Plan

You make 48 payments of 158.50. That gives you the total of what you have paid back.

Equation

Total payment = months * monthly payments

Solution

Total Payment = 48 * 158.50

Total Payment = 7608

Cost of the loan

Finance charge = amount paid - amount loaned

Finance charge = ?

amount paid = 7608

amount loaned = 6800

Finance charge = 7608 - 6800

Answer: Finance charge = 808

for number 8 we have to use the equation πr^2, so plugging 9 into the equation would give us π(9^2). squaring the 9 gives us 81, and 81 times π equals ~25.

for number 9 we need to use the same equation, πr^2 to find the area, but since we are given the diameter we do not need to use r^2. Instead, we can use π(106) which gives us 333.

Now, let’s solve for the area of the triangle.
The base of the triangle is 20cm and the height of the rectangle is 16-7=9cm

The area is 1/2*20*9

The surface area is 168 yd^2.

There are 2 rectangles with the dimensions of 6 by 2.

6 x 2 = 12, times 2 (since there are two equal ones) = 24.

There are 2 rectangles with the dimensions of 9 by 2.

9 x 2 = 18, x 2 = 36.

Lastly, there are two rectangles with the dimensions of 9 by 6.

9 x 6 = 54, x 2 = 108.


Now, we must add them all up.

3. Amy Schorling is age 24 and is unmarried. She uses her vehicle
for business. Her driver-rating factor is 1.85. Her vehicle is
classified D-14. Her insurance consists of $25,000 property
damage, 25/50 bodily injury, $50-deductible comprehensive, an
no collision coverage.
a. What is her annual premium?
b. How much is her annual premium if she includes
$50-deductible collision coverage?

Answers

Based on Amy Schorling's driver rating factor, vehicle classification and bodily injury coverage, her annual premium is $576.46.

If she includes the $50-deductibel collision coverage, her insurance premium becomes $1,067.08.

How much is Amy Schorling's annual premium?

At $25,000 property damage, her 25/50 bodily injury coverage premium is $206.40.

This should be added to her $50 comprehensive deductible D-14 vehicle classification of $105.20.

Annual base premium:

= 206.40 + 105.20

= $311.60

Annual premium:

= Annual base premium x Driver rating factor

= 311.60 x 1.85

= $576.46

How much is the annual premium including collision coverage?

The annual base premium becomes:

= 311.60 + 265.20

= $576.80

Annual premium becomes:

= 576.80 x 1.85

= $1,067.08

The first missing quantity is force due to gravity, and it is 215.1 N.

The second missing quantity is distance between the statellite and the Earth, determined as 6,000 km.

Force between two masses

The force between two masses is determined by applying Newton's law of universal gravitation as shown below;

[tex]F = \frac{GMm}{R^2}[/tex]

where;

M is mass of Earth = 5.97 x 10²⁴ kgm is mass of the satelliteR is the distance between the satellite and the EarthG is universal gravitation constantFirst missing quantity

The first missing quantity is force due to gravity, and it is calculated as follows;

[tex]F = \frac{(6.67 \times 10^{-11} ) \times (5.97 \times 10^{24}) \times (700)}{(36,000 \times 10^3)^2} \\\\F = 215.1 \ N[/tex]

Second missing quantity

The second missing quantity is distance between the statellite and the Earth,

[tex]R^2 = \frac{GMm}{F} \\\\R^2 = \frac{(6.67 \times 10^{-11})(5.97 \times 10^{24})(1000)}{11,000} \\\\R^2 = 3.62 \times 10^{13}\\\\R = 6,000 \ km[/tex]
