A student needed to prepare 500mL of 1X TAE buffer to run a QC gel. The stock solution in the lab is 5X TAE. What volumes of sto

Xelga [282]

Answer:

you need 100ml of 5X TAE and 400ml of water.

Step-by-step explanation:

You need to use a rule of three:

$C_1V_1=C_2V_2$

where:

$\left \{ {{C_1= 5X} \atop {C_2=1X}} \right.$

and

$\left \{ {{V_1 = V_{TAE}} \atop {V_2=500ml}} \right.$

Therefore:

$V_{TAE} = \frac{V_2*C_2}{C_1}$

$V_{TAE} = 100ml$

Then just rest the TAE volume to the final Volume and you get the amount of water that you need to reduce the concentration.

if the line AB with A(-1,5) and B(3,7) is perpendicular to the line CD WITH C(7,11) AND D(X,23). THEN X=?

MissTica

Answer:

x=1

Step-by-step explanation:

slope AB = (7-5) / (3 - -1) = 2 / 4 = 1/2

slope CD = (23-11) / (x-7) = 12 / (x-7)

12 / (x-7) = - 2 ... perpendicular to AB slope 1 = - 1/slope 2

-2 (x-7) = 12

-2x + 14 = 12

-2x = -2

x = 1

What is the slope of a line that is parallel to the line -6y=8x-4?

lesya692 [45]

Answer:

-4

Step-by-step explanation:

-6y=8x-4

0=8x+6y-4---(i)

slope (m1)=-coefficient of x

coefficient of y

=-8

= -4

As the lines are parallel,

m1=m2

so,

The slope of line parallel to the line having equation -6y=8x-4 is -4
