Answer:
5 to 3 ratio
Step-by-step explanation:
Vadim has 18 books. The total books is 30.
30 to 18 simplified is 5 to 3.
Depreciation of 11% per year means that the price is multiplied by 89% (0.89) every year. Do this 11 times or use exponents
Final price:
207000*(0.89^11) = 57446.083
Answer:
No. In order to be a right triangle, the lengths of the 2 smaller sides must equal the length of the longest side.
In other words, these 3 sides must work with the Pythagorean theorem.
A^2 + B^2 = C^2
25^2 + 30^2 is NOT 30^2
This is a triangle, just not a right triangle.
