Answer:
Rate of simple interest charge by bank is 9.125
Step-by-step explanation:
Given as :
The principal = Rs 8000
The amount paid = Rs 8640
The time period = 320 days
Let the rate of simple interest = R
<u>So from simple interest method </u>
Simple Interest = 
∵, Interest = Amount - principal
Or, Interest = Rs 8640 - Rs 8000 = Rs 640
∴ Rs 640 = 
Or, 64000 × 365 = 8000 × 320 × rate
Or 23360000 = 2560000 × rate
So, rate = 
∴ Rate = 9.125
I.e rate of simple interest charge by bank is 9.125 Answer
Answer:
113.1 is the volume of the sphere.
Answer:
31.5
Step-by-step explanation:
To find the area of the triangle:
A=Lenth * Width
A=7*3=21
To find the area of the triangle:
Area=base * height/2
A=7*3/2
7*3=21
21/2=10.5
21+10.5=31.5
B. s/2 meaning the number of students divided by two
Answer:
1. C = $100 = .25(m)
2. C = $150
3. 800 = m
Step-by-step explanation:
1. C = $100 (flat fee rate) + .25m
2. c = $100 + .25(200 miles)
↓
c = $100 + 50
↓
c = 150
3. 300 = 100 + .25(m)
-100 -100 (subtract on both sides)
--------------------------------
200 = .25(m)
------------------- (divide by .25 to get m by itself)
.25
Therefore being 800 = m
