Answer:
78 ml of 7% vinegar and 312 ml of 12% vinegar.
Step-by-step explanation:
Let x represent ml of 7% vinegar brand and y represent ml of 12% vinegar brand.
We have been given that chef wants to make 390 milliliters of the dressing. We can represent this information in an equation as:
We are also told that 1st brand 7% vinegar, so amount of vinegar in x ml would be .
The second brand contains 12 vinegar, so amount of vinegar in y ml would be .
We are also told that the chef wants to make 390 milliliters of a dressing that is 11% vinegar. We can represent this information in an equation as:
Upon substituting equation (1) in equation (2), we will get:
Therefore, the chef should use 78 ml of the brand that contains 7% vinegar.
Upon substituting in equation (1), we will get:
Therefore, the chef should use 312 ml of the brand that contains 12% vinegar.

<h2>16</h2>
Step-by-step explanation:
step one:
given data
we are given the equation of the circle as
----------------1
We know that the general equation for a circle is
--------------2
comparing the two equations above, we can immediately compare the term on the other side of the equality sign that is
r^2=64
square root both sides
r=√64
r=8
since the radius is 8, hence the diameter is
d=2
r= 2*8
=16

The answer is A: see plot
Step-by-step explanation:
Because the coin has only two sides, the probability of him getting tails is 1/2, and because of the dice has six sides, the probability of him getting a 3 is 1/6.
