Answer:
a) Interest earned = $36
New Balance = $336
b) Interest rate = 0.05 or 5%
New Balance = $517.5
c) time t = 5
New Balance = $612.5
d) Principal Amount = $675
New Balance = $783
Step-by-step explanation:
We are given:
a) Principal (P) = $300
Rate (r) = 3% or 0.03
Time (t)= 4 years
Interest earned = ?
The formula used is: 
Putting values and finding interest

So, Interest earned = $36
New Balance = Principal + Interest = 300+36 = $336
b) a) Principal (P) = $300
Rate (r) = ?
Time (t)= 3 years
Interest earned = 67.50
The formula used is: 
Putting values and finding rate

So, Interest rate = 0.05 or 5%
New Balance = Principal + Interest = 450+67.50 = $517.5
c) Principal (P) = $500
Rate (r) = 4.5% or 0.045
Time (t)= ?
Interest earned = $112.50
The formula used is: 
Putting values and finding time

So, time t = 5
New Balance = Principal + Interest = 500+112.50 = $612.5
d) Principal (P) = ?
Rate (r) = 8% or 0.08
Time (t)= 2 years
Interest earned = 108.00
The formula used is: 
Putting values and finding Principal

So, Principal Amount = $675
New Balance = Principal + Interest = 675+108 = $783
Answer:
72°
Step-by-step explanation:
The circle is divided into 5 parts.
A circle measures 360°.
360/5 = 72°
hope this helps!! p.s. i really need brainliest :)
Mrs. Beachy would drive 53mph. How I did it:954÷18(18 can't go into 9.... 95?)Yes, 5 times.954÷18= 5 -(Okay... 95-90 is 5, drop the four... 54?)18x3 is 54!954÷18=54! So the answer is 54mph (Right? I am sure I did that right...)
