The two general types of diodes are the semiconductor and the vacuum tube diode. Both types have their own particular applications and advantages.

The formula for the perimeter of a rectangle isP= 2L+ 2W. In this case,P= 100 and L= 1.5W.
100 = 2(1.5W) + 2W
100 = 3W+ 2W
100 = 5W
W= 100/5
W= 20. The width of the rectangle is 20 inches. Becuase the length is 11/2 the width, 1.5 × 20 = 30.

To determine the amount of interest earned, multiply the principal ($3,000) by the interest rate (6%) and the number of years interest accrues (1 year): $3,000 0.06 1 = $180. Add the interest earned to the principal to show how much total money the teacher would have: $180 + $3,000 = $3,180.

The relative concentration of glucose is maintained by the combined action of insulin from the pancreas and adrenaline from the adrenal medulla.
