Hi, first you find the VR of the "teeth" so 56/20= 2.8 VR= dE/dL dE= 2 x pI x 180 = 1130.97 dL= 2 x pI x 300 x ( VR of the "teeth" in this case 2.8 ) = 5277.88 Therefore 1130.97/5277.88 = 0.214 Hope it helped Good Luck!

First we have to see which formula to use…so we do: M= $4000 N= ?? r= 12%/4 = 3% (compounded quarterly) n= 4 x 10 = 40 quarters in 10 yrs. So we use the present value formulae. (1+0.03)^40 - 1 ---------------------- N = 4000 0.03(1+0.03) ^ 40 So...

A) She borrows $8500 plus $7.50 stamp duty and $15 per year for 3 years on insurance so 8500+7.50+(15x3) = $8552.50 B) I=PRN. P= 8552.5. R=13.5% divided by 12(months) = 1.125% Interest per month. N= (3x12) = 36 months. Therefore 8552.5x1.125/100 x 36 = $3463.76 C) $3463.76 + $8552.5 =...

Hi, i dont quiet understand the question however, is it referring to upper and lower limit? if it is then the solution is below: 5.8 is the lengths & it can go up or down by 0.1 so 0.1/2 = 0.05 therefore +/- 0.05 lower limit --> 5.8-0.05= 5.75 therefore 5.75x5.75= 33.0625m^2 upper...

The multiply choice was easy, however the long answers didnt really go my way. What did you guys get for the bearing question. The question which wants the angle from point C back to point A? i think i stuffed it up i made up some type of solution which i think is wrong.
