Answer:

40.47°, 49.53°

Step-by-step explanation:

Complementary angles add up to 90

7r + 5 + 8r + 9 = 90

15r + 14 = 90

15r = 76

r = 76/15

7r + 5 = 7(76/15) + 5 = 40 7/15

8r + 9 = 8(76/15) + 9 = 49 8/15

DanielleElmas [232]

Answer:

6.48 dollars total,

Step-by-step explanation:

First, you would want to multiply the amount of money per pound, by the amount of pounds. 1.60 multiplied by 4 1/2 or 4.5, would equal to 7.2 dollars. In order to find 10% of 7.2, your would need to multiply 7.2 by 0.10, which would give you 0.72. Then you would subtract 7.2 by 0.72 to get 6.48. So your answer would be 6.48 dollars. Hoped this helped.

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.

<h3>Force between two masses</h3>

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

F = \frac{GMm}{R^2}

where;

  • M is mass of Earth = 5.97 x 10²⁴ kg
  • m is mass of the satellite
  • R is the distance between the satellite and the Earth
  • G is universal gravitation constant
<h3>First missing quantity</h3>

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

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

<h3>Second missing quantity</h3>

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

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
