There are some chocolate in a box 1/4 of the chocolates contains nuts

The rest of the chocolate do not contain nuts

Write down the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts
Give your awnser in the form 1:n

1:3

Step-by-step explanation:

The part that contains nuts = 1/4

The part that do not contain nuts = 1-1/4 =3/4

We need to find the ratio of the number of chocolates that contain nuts to the number of chocolates that do not contain nuts. It can be calculated as follows :

So, the required ratio is 1:3.

the answer i think is a)

step-by-step explanation:

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.
