Answer:
hence rate interest r = 41.176%
Step-by-step explanation:
The amount borrowed= $680
amount payed back = $750
therefore, interest incurred = 750-680= $70
time, t= 3 months = 3/12= 0.25 years
rate%, r
we know that SI= 
70= 
r=
hence rate interest r = 41.176%
Answer:
2500pi^2 units
Step-by-step explanation:
Circumference = pi * diameter
Circumference = pi * 100
Radius = diameter/2
Radius = 50
Area = pi * radius^2
Area = pi * 50^2
Area = pi * 2500
Area = 2500pi^2 units

Answer: 20% off
Step-by-step explanation:
35.00 times .20 = 7.00
