it takes 12.5g of fruit to make 5 liters of juice. how many grams fruit it will take to make 20.5 liters of juice?

51.25g

Step-by-step explanation:

Just simply use unitary method:

To make 5 litres of juice, fruits needed is 12.5g

To make 1 litre of juice, fruits needed is 12.5g÷5

To make 20.5 litres of juice, fruits needed is (12.5g÷5) × 20.5

                                                                           = 51.25g

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
