A scientist had 3 1/2 liters of vinegar. He poured 2/3 of the vinegar into beaker. He then used 3/5 of the vinegar in the beaker
valentinak56 [21]

Answer:

A)2100 ml

Step-by-step explanation:

Given total vinegar is 3 1/2 liters and the used vinegar is  3/5 of the vinegar in the beaker:

#First calculate the amount of vinegar not poured in the beaker:

V_o=V_t-V_b\\\\=3\frac{1}{2}(1-\frac{2}{3})\\\\=1\frac{1}{6}

#Calculate amount of vinegar used in experiment:

V_b=\frac{2}{3}V_t=\frac{2}{3}(3\frac{1}{2})=2\frac{1}{3}\\\\V_u=\frac{3}{5}V_b=\frac{3}{5}\times 2\frac{1}{3}=1\frac{2}{5}

#The unused vinegar is therefore calculated by subtracting the used vinegar from the total at the start of the experiment:

V_r=V_t-V_u\\\\=3\frac{1}{2}-1\frac{2}5}\\\\=2\frac{1}{10}\times 1000\ ml\\\\=2100\ ml

Hence, the unused vinegar is 2100 ml

-6x+4y=-12 in slope intercept form
cricket20 [7]

Answer:

x= 2 /3 y+2

Step-by-step explanation:

Let's solve for x.

−6x+4y=−12

Step 1: Add -4y to both sides.

−6x+4y+−4y=−12+−4y

−6x=−4y−12

Step 2: Divide both sides by -6.

−6x /−6 = −4y−12 /−6 x= 2 /3 y

=x= 2 /3 y+2

To find the x coordinate of the midpoint, add the x coordinates and divide by 2

x = (3+5.5) /2 = 8.5/2 =4.25

To find the y coordinate of the midpoint, add the y coordinates and divide by 2

y = ( 4+0)/2 = 4/2 =2
