the answer is 360
4/100 x 90 0.9 x 4 = (3.6)
90 x 4 = 360
45 x 4 =45+45+45+45=90+90=180
2 x 3 x 3 x 5 = 90
The first five positive integer multiples of 90 are: 1 x 90 = 90 2 x 90 = 180 3 x 90 = 270 4 x 90 = 360 5 x 90 = 450
2 goes into both numbers 4 and 90 because 2 x 2 = 4 and 2 x 45 = 90.
The first ten positive integer multiples of 90 are: 1 x 90 = 90 2 x 90 = 180 3 x 90 = 270 4 x 90 = 360 5 x 90 = 450 6 x 90 = 540 7 x 90 = 630 8 x 90 = 720 9 x 90 = 810 10 x 90 = 900
Suppose the angle is x degrees. Then its complement is 90 - x deg So 90 - x = 4*x ie 90 = 5x or x = 18 degrees.
four quarters is 4 x 1/4 = 4/4 = 1, ie the whole. So four quarters of 90 is 90.
4/90 x 100 = 4.4 recurring (that is, 4.4444..) percent.
The least common multiple of 45 and 90 is 90, so you can leave 45 out of the calculations entirely. 40 = 4 x 10; 90 = 9 x 10. Thus, the LCM of 40 and 90 is 4 x 9 x 10 = 360.
(x+83+90+96) divided by 4 = 90 Multiplying both side of the equation by 4 gives you: x+83+90+96=360 x=360-83-90-96 x=91 which is the fourth number
