dude, use a calculator
Step-by-step explanation:
The points A, B and C are collinear and AC + CB = AB.
From that, we can conclude that C is between A and B. Because if you split AB, C will appear (AB = AC + CB).
Hope this helps! :)
Given:
Total amount invested = $9,000
interest rates = 4% and 6%
Let x be the part of 9,000.
Note that annual return on each investment is the same.
0.04x = 0.06(9,000 - x)
0.04x = 540 - 0.06x
0.04x + 0.06x = 540
0.10x = 540
x = 540/0.10
x = 5,400
0.04x = 0.06(9,000 - x)
0.04(5,400) = 0.06(9,000 - 5,400)
216 = 0.06(3,600)
216 = 216
total interest for the year : 216 + 216 = 432
Interest = pricipal * interest rate * term
432 = 9,000 * interest rate * 1 yr
432/9,000 = interest rate
0.048 = interest rate
Interest rate would be 4.8% to get the same interest from the whole 9,000.
Answer: 2/3 yard
Step-by-step explanation: First, Kevin cut a plank a yard long. That means that he has a plank thats a yard long. Next, he painted 1/3 of the plank black. Before, 3/3 (basically equals to 1 yard long) of the plank was unpainted. So, the equation will be 3/3 - 1/3 which is equal to 2/3 yard.
