gavmur [86]
The area of a rectangle is the result of multiplying its length times its width. So the rectangles length and width are factor pairs of the area.

The number 36 has four non-equal, whole number factor pairs: (1,36) ; (2,18) ; (3,13) ; (4,9)

*note : (6,6) makes a square not rectangle

The number 15 has only two whole number factor pairs (1,15) and (3,5)

A plane flies 1.4 hours at 150 mph on a bearing of 10. It then turns and flies hours at the same speed on a bearing of . How far
Gnesinka [82]

Answer:

The answer is "1035.76 miles"

Explanation:

The aircraft flies at 120 mph for 1.5 hours at a 10^{\circ} bearing, then flies at the very same speed at 100^{\circ} bearings for 8.5 hours.

However an angle of 100-10 = 90^{\circ} between displacements

First shifts= 1.5 \times 120 = 180\  miles.

Second shift = 8.5\times 120 = 1020\ miles.

These two shifts are at 90^{\circ} and therefore the final shift is:

\to \sqrt{180^2+1020^2}=1035.76 \ miles
