Answer:
Even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
Step-by-step explanation:
Given that you invested $ 3000 between two accounts paying 4% and 8% annual interest respectively, to determine how much was invested at each rate if the total interest eamed for the year was $ 520, the following calculation must be performed:
3000 x 0.04 + 0 x 0.08 = 120
1500 x 0.04 + 1500 x 0.08 = 180
3000 x 0.08 + 0 x 0.04 = 240
Thus, as can be seen, even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
The answer is 16 pi - 16. The area of each triangle is 8, so both triangles are 16. The area of the circle is pi times the radius squared, 16 pi.
The number is is 5 because,
6 * 5 = 30,
and 30 - 4 = 26, this is basically an equation,
6 * 30 - 4 = 26
