It's standard form would be: 9 * 10^3
Interest+original=amount to pay off
intrest=prinicpal times rate times time
interest=2000 times 3 times 0.08
interest=480
so total is 2000+480 or 2480 to pay off
If you are learning about how to calculate the mean of something, than to estimate the height just find the mean, all the peaks added together, and divided by the amount of numbers (27 + 18 + 12 = 57 ... 57 divided by 3 = 19. Your mean is 19)
Please give more information, can't help without more information.
7 mm wide
To solve this, you can use the Pythagorean theorem.
A triangle's sides is length squared + length squared = hypotenuse squared. We know the hypotenuse and one side of the triangle. So, we can follow the equation 24 squared + x squared = 25 squared
To solve this, find the value of 24 squared and 25 squared. 24 squared = 576, and 25 squared = 625, so your equation becomes 576 + x squared = 625
Next, you subtract your known values. 576 + x squared – 576 = 625 – 576 = 49, so x squared = 49
For the last step, find the square root (√) of 49, which is 7. So x = 7 mm
And you can check: 24 squared + 7 squared = 25 squared
