Answers

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]

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.

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

Answers

The area is 230cm we can split the shape into different parts a rectangle and a triangle let’s first solve with the area of the rectangle. The width of the rectangle is 20cm and the height of the rectangle is 7cm so, the area is 7x20=140cm
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
=90cm

We added the two values together to get the combined area of the shape. 140+90=230cm

Answers

a. Two pairs complementary angles are: ∠DCM and ∠DMC; ∠MGF and ∠GMF

b. m∠GMF + m∠CMG + m∠DMC = 180°

What are Supplementary Angles and Complementary Angles?

If the sum of two angles equal 90°, they are complementary angles.

If the sum of two angles equal 180°, they are supplementary angles.

Given square CDFG:

a. Two pairs of angles that are complementary are: ∠DCM and ∠DMC; ∠MGF and ∠GMF

b. m∠GMF + m∠CMG + m∠DMC = 180° (angles on a straight line)

Therefore, three angles that sum up to 180° are: ∠GMF, ∠CMG, and ∠DMC.

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.

24 + 36 + 108 =
