Based on the orbital period of the planet in earth years, and the distance it is rotating, the mass of the star that the planet is orbiting is 3 solar masses.
<h3>What is a solar mass?</h3>
Because the sun is so heavy, it needed to have a special unit that could adequately reflect this mass.
Solar masses was the term that scientists came up with. In terms of the Earth's mass, a single solar mass means that the body is 333,000 times the mass of the Earth.
When given the orbital period of a planet, and the distance it is orbiting around a sun, you can find the solar mass by the formula:
= Distance planet is rotating³ - Orbital period²
Solving gives:
= 1.2³ / 0.76²
= 2.99
= 3 solar masses
In conclusion the mass of the star is 3 solar masses

49/70 = 0.7
0.7*100 = 70
Answer:
A is the answer! I think you know because the formula is given at the top.
Answer:
<h2>y = 7</h2>
Step-by-step explanation:
We know that the sum of the measures of angles on one side of the parallelogram is 180°.
We have the equation:
(6x - 12) + (132 - x) = 180
6x - 12 + 132 - x = 180 <em>combine like terms</em>
(6x - x) + (-12 + 132) = 180
5x + 120 = 180 <em>subtract 120 from both sides</em>
5x = 60 <em>divide both sides by 5</em>
x = 12
Opposite angles in the parallelogram are congruent.
Therefore:
6y + 18 = 6x - 12
Put the value of x to the equation and solve it for y:
6y + 18 = 6(12) - 12
6y + 18 = 72 - 12
6y + 18 = 60 <em>subtract 18 from both sides</em>
6y = 42 <em>divide both sides by 6</em>
y = 7
