Answer:
Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:
Answer: 690
Step-by-step explanation:
So, you should do
46,000 * 9% = 4,140
4,140 divided by 6 = 690
So your answer is 690

<u>Finding the unit rate of the graph</u> :
- Take 2 points and find the slope
- ⇒ (0,0) and (12, 25)
- ⇒ m = 25 - 0 / 12 - 0
- ⇒ m = <u>25/12</u>
- The equation is : <u>y = 25/12x</u>
Now, the equations with greater unit rates (in increasing order) are :
Answer:
A) infinitely many solutions
Step-by-step explanation:
2x - y = 8
4x - 2y = 16
simplify the first equation
2x - y = 8
2x = 8 + y
2x - 8 = y
y = 2x - 8
substitute y for 2x - 8 in the second equation
4x - 2y = 16
4x - 2(2x - 8) = 16
4x - 4x + 16 = 16
4x - 4x = 16 - 16
0x = 0
since no matter what x is, 0 = 0, the answer is infinitely many solutions
