LEMON SQUASH 1 part concentrate
to 2 parts water

If you put 140ml of water in a glass, how much concentrate should be added?

70ml

Step-by-step explanation:

concentrate is half of water ( 140/2=70)

3 parts of 70ml   in total    (210ml )  

2 parts of water70+70 of water= 140

1 part of concentrate 70 of concentrate

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
