How many years till 2025?
12
What times what equals 2025?
There are infinitely many possible answers. x ≥ 45 and let y = 2025/x Then xy = x*2025/x = 2025 and, since x ≥ 45, then y ≤ 45 so that (x, y) is always distint from (y, x). Then, since these are infinitely many choices for x, there are infinitely many answers.
How many numbers from 1976 to 2013 are perfect square numbers?
None. √1976 is "44 and a bit" → first perfect square ≥ 1976 is 452 = 2025 As 1976 is not a perfect square and the first perfect square greater than 1976 is 2025, and 2025 is greater than 2013, there are no perfect squares from 1976 to 2013.
What do aeronautical engineers use ratios and proportions for?
I'm sure they use ratios and proportions at many different points in the practice of their profession. One obvious application is in construction of exact scale models of aircraft and their components for wind-tunnel tests.
What do engineers use trigonometry for?
Engineers use trigonometry anywhere that involves non-right angles. That includes building cars and buildings, bridges, and many other structures. they also use trigonometry when dealing with fields, like magnetic and electric fields. Also, trigonometry is very important with engineers who deal with waves, such as sound or light engineers.
