How much tomato juice is needed for a group of four people if each person gets 1/3 cup of juice how much tomato juice is needed if they each get 2/3 cup of juice

,

Step-by-step explanation:

Given:

Number of people in a group = 4

Each person gets cup of juice =

Question asked:

How much tomato juice is needed for a group of four people ?

How much tomato juice is needed if they each get 2/3 cup of juice ?

Solution:

Unitary method:

In case of each person gets up of juice.

1 person gets cup of juice =

4 persons gets cup of juice =

Therefore, is needed for a group of four people.

In case of each person gets cup of juice.

1 person gets cup of juice =

4 persons gets cup of juice =

Thus, cups of tomato juice is needed if they each get cup of juice.

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.
