90 = XC
90
Depends on what you are wanting to figure. Here are a couple samples:Tons to CWT - 90 Tons = 1800 CWT to figure this you do the calculation of 90 * 20 (This is the shortcut)the long route is 90/100 = .9 then .9 * 2000 = 1800 (2000 lbs in a Ton)
Both a square and a rectangle have 4 angles of 90 degrees.
90
The digit 90 has only one applicable significant figure.
119.7, couldn't figure that out yourself? 90 x .133 = 119.7
A square is a four-sided figure with four 90-degree angles.
75% of 90 = 75% * 90 = 0.75 * 90 = 67.5
Before that instruction, the problem gave you two numbers, and one numberis SMALLER than the other one.Now, the problem wants you to take the smaller one, figure out what 3 times itis, and then either increase that by 90 or multiply that by 90.
To rotate a figure 90 degrees clockwise about the origin, simply swap the x and y coordinates of each point and then negate the new y-coordinate. This is equivalent to reflecting the figure over the line y = x and then over the y-axis.
