Algebra 2
My error I just reread that the first 1/2 hour is included. I am quite sure that the it is $30 for each additional 1/2 hour the equation is: Let H = the number of HALF HOURS $200 = $50 + (H-1))$30 similarly $150 = (H-1)*$30 5 = H=1 adding 1 to each side: H= 6 This is the numbe...

I think there is some confusion here. Let H = the total hours $200 = $50 + (H-1)*$30 Remember that the first hour is included in the $50. subtract $50 from both sides $150 = (H-1)*$30 divide both sides by $30 5 = H -1 add 1 to both sides: H = ??

You are very welcome.

You're welcome, but I am not sure what you mean by reverse FOIL. First terms: x and x Outer terms: x and -5/4 Inner terms: -5/4 and x Last terms : -5/4 and -5/4 I just want to be sure you have a good understanding about the order.
Algebra B
OK, (x-5/4)^2 = (x-5/4)(x-5/4) multiplying (remember FOIL--first, outer, inner, last) = x^2 -(5/4)(x) - (5/4)(x) + (5/4)^2 = x^2 - (10/4)(x) + (5^2)/(4^2) = x^2 -(5/2)(x) + (25)/(16) Does that help?

Which side (left or right) is puzzling?
Physics
Be careful of units. You expressed the runway length in m (meters), but the takeoff speed is expressed in mi/h (miles/hour). You will need to do some units conversion.
computer architecture
Modern PCs have a word size of 32 or 64 bits. Early IBM PCs used an Intel 8088 which had an 8 bit data path.
ALGEBRA/AM I CORRECT?
my misspelling... You have AN eror.
ALGEBRA/AM I CORRECT?
You have and error. 3X + 240 + 36X = 6 39X = -234 X = ?
