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
Answer:
Step-by-step explanation:
Remark
The formula for the circumference is C = 2*pi * r
Givens
r = 50 feet
pi = 3.14
Solution
C = 2* 3.14 * 50
C = 314 feet
So one turn of the ferris wheel would allow a person to travel 314 feet around the circle.

Answer:
17/24
Step-by-step explanation:
(a+b)÷2
a= 2÷3
b= 3÷4
=(2/3 + 3/4)÷2
=(8+9/12)÷2
=17/24
