Rhianna has £25 to spend on plants. Each plant costs £3.95
She buys as many plants as she can.
How much change should Rhianna receive from £25?

£0.33

Step-by-step explanation:

Rhianna has £25.

1 plant costs £3.95, she buys all of them.

25/3.95 = 6.329114

She buys a total of 6 plants.

With £0.33 remaining, which is the change.

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.

so what is the question
