Me with this math problem. only answer if you can explane your answer. \ question is on the picture for .

1 cm = 0.393701 inches.

Multiply total cm by conversion factor:

91 cm x  0.393701 = 35.8268 inches per day.

1 day = 24 hours

Divide total inches by number of hours:

35.8268 inches / 24 hours = 1.4928 inches per hour. ( Can round to 1.5 inches per hour if necessary)

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.

the diver is 33 feet below the surface.

step-by-step explanation:
