90 = 9.0 x 10^(1)
5/6 x 90 is 75.
Complementary angles add up to 90 degrees and so 4 times 22.5 degrees = 90 degrees or if you mean 4 times 90 degrees then it is a full turn of 360 degrees
4.5 X 2 = 9.0
The question was cut up a bit. Some possibilities: 90 minus 2 [ 90 - 2 = 88 ] 90 plus 2 [ 90 + 2 = 92 ] 90 times 2 [ 90 * 2 = 180 ] 90 divided-by 2 [ 90 / 2 = 45 ] 90 to-the-power-of 2 [ 90^2 = 8,100 ] 90 equals 2 [ No Solution ] Add on to the discussion to edit the question, if it wasn't answered.
90 feet in scientific notation is: 9 x 101feet
9.0 x 101
9.0 x 10^1
90 can be written in scientific notation as 9.0 x 10^1. This means that 90 is equal to 9.0 multiplied by 10 raised to the power of 1.
In scientific notation it would be: 1.0*10^90
9 x 10^7
Use scientific notation. 9 x 10^10 times 2 x 10^2 = 18 x 10^12 Eighteen trillion
It is: 270/300 times 100 = 90%
300
It is: 7.0*10^-4
It is a very huge number and would be expressed in scientific notation as 9.0*1090
