Answer:
The amount of the bill is dependent on the number of texts sent. Let y be the bill amount and x the number of texts. Then x is independent and y is dependent. This is because x can be any non-negative number, but y depends upon it. You cannot find the bill without knowing the number of text messages, right?
Formula for compound interest is
Interest = Amount - Principal
Interest = 
- P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest = 
- 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest = 
- 400
So pair of equations for Jaina and Tomas are
Interest = - 300
Interest = - 400
Because logarithms were a lot less time-consuming than other methods of finding roots. They were also more accurate in the sense that it was harder to make a mistake.
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
Answer:
n = 5
Step-by-step explanation:
180(n − 2) = s
180(n − 2) = 540
180n - 360 = 540
180n - 360 + 360 = 540 + 360
180n = 900
(1/180) 180n = 900 (1/180)
n = 5
