The midpoint of a segment can be found using the formulas for a directed line segment, x = (a 4 b )(x2 – xx) + x; and y= ]142 – Yz) + yy. When using these formulas to find a midpoint, which is true?
a
a +
a = 1 and b = 2
a = 2 and b = 1
a = 1 and a + b = 2
a = 2 and a + b = 2

Acompany manufactures large valves, packed in boxes. a shipment consists of 1500 valves packed in 75 boxes. each box has the outer dimensions 1.2 x 0.8 x 1.6 m and the inner dimensions 1.19 x 0.79 x 1.59 m. the boxes are loaded on a vehicle (truck + trailer). the available capacity in the vehicle combination is 140 m3. each valve has a volume of 0.06 m3. - calculate the load factor on the box level (%). - calculate the load factor on the vehicle level (%). - calculate the overall load factor (%).
