6.That's a rectangle oriented parallel to the axes, width parallel to the x axis of 7 - -3 = 10 and length along y of 1 - - 4 = 5, so an area of 10(5)=50
Answer: 50
Answer:
The rate of Simple Interest is 6.5 %
Step-by-step explanation:
Given as :
Principal = $ 4000.00
Amount = $ 5300.00
The time period of loan = 5 years
Let The rate of simple interest = R
Now,
From Simple Interest method
Simple Interest =
And , Simple Interest = Amount - Principal
So , Simple Interest = $ 5300.00 - $ 4000.00
Or, Simple Interest = $ 1300
Now, Simple Interest =
So, $ 1300 =
Or, $ 1300 × 100 = $ 4000 × Rate × 5
Or, Rate = 
Or, Rate = 6.5
Hence The rate of Simple Interest is 6.5 % Answer
This is True Because for each triangle plane, B is one of its points
