Answer: the equation that best represents the data that is in the table is y = 5x. You can corroborate it by substituting the x values of the table and verifying that you get the "y" values
Step-by-step explanation: hopes this helps
Answer:
angle x is an exterior angle of the triangle
Answer:
51
Step-by-step explanation:
A = Surface area of the Earth = 
Total number of people on Earth = 7.594 billion as of 2018 = 
We need to find the number of people living in each square km of land area.
So, we need to divide the number of people by the land area of the Earth.



So, 51 people will inhabit each square km of land area.
Answer:
Ashley=1450
Ben= 1080
Mischa= 1210
Step-by-step explanation:
M= Mischa
B= Ben
A= Ashley
M+B=2290
A+B=2530
M+A=2660
M-A= -240
so 2M = 2420, and M= 1210
Then
1210 + B = 2290
B= 1080
Then
1210 + A= 2660
A= 1450
Answer:
193 mg
Step-by-step explanation:
Exponential decay formula:

- where Aₜ = mass at time t, A₀ = mass at time 0, r = decay constant (rate), t = time
Our known variables are:
- 1998 to the year 2004 is a total of t = 6 years.
- The sample of radioactive isotope has an initial mass of A₀ = 360 mg at time 0 and a mass of Aₜ = 270 mg at time t.
Let's solve for the decay constant of this sample.
Using our new variables, we can now solve for Aₜ at t = 7 years, since we go from 2004 to 2011.
Our new initial mass is A₀ = 270 mg. We solved for the decay constant, r = 0.04794701.
The expected mass of the sample in the year 2011 would be 193 mg.
