Hey!
---------------------------------------
Solution:
77.50 = 0.15x + 10
77.50 - 10 + 0.15x + 10 - 10
67.50 = 0.15x
0.15x = 67.50
0.15x/0.15 = 67.50/0.015
x = 450
---------------------------------------
Check:
77.50 = 0.15(450) + 10
77.50 = 67.50 + 10
77.50 = 77.50
---------------------------------------
Answer:
450 text messages can be sent when the monthly charge is $77.50!

Hope This Helped! Good Luck!
I've never done this type of problem before so I might be wrong but I think the answer is 20420352.25 cm
I just took the circumference (204.2035225) and multipled 100,000 which seems too simple to be right
Answer:
slope intercept form is : y = mx + b
where m is the slope and b is the y-intercept.
The slope, m = (y' - y)/(x' - x)
Is found using the two pints.
The apostrophe is used to denote the other point, different from point (x,y).
once you have the slope, m for the equation y = mx + b ; use one of the points as (x,y) to solve for b.
M=-1/3
that is the answer
Answer:
0.999
Step-by-step explanation:
Assuming that there are ten questions.
This yields:
Each answer has an equal chance of being selected.
Therefore, the probability of the answer = 
But we assume 10 questions, therefore, the probability will be given as follows:
P (Ans) = 
= 
= 0.000977
This is the probability of getting them all wrong.
The probability of getting the answer right is given by p(Right answer) = 1 -0.000977 = 0.9990
