184 milliliters of the first brand and 46 milliliters of the second brand
Step-by-step explanation:
Step 1:
Let x be the number of milliliters of the first brand in the final mixture
Since the chef requires 230 milliliters, 230 - x would be the milliliters of dressing of the second brand
Step 2:
The first brand contains 6% vinegar, and the second brand contains 11% vinegar
Hence we have,
x * 6/100 + (230-x) * 11/100 = 230 * 7/100
0.06 x + 25.3 - 0.11 x = 16.1
0.05x = 9.2 => x = 184
Hence the 184 milliliters of the first brand is to be used
Step 3 :
Quantity of the second brand to be used is 230 - x = 230 -184 = 46 milliliters.
Answer:
the correct answer is point b
Answer: c.A is the set of rational numbers
Step-by-step explanation:
B ⊆ A means that every element of B is an element of A
B = { -13 , -9 , -7 , - 3 }
The element of B are negative integers , this mean that the element of A must also be integers therefore :
Option a is correct.
Option b is also correct
Rational numbers are numbers that can be express in the form a/b , examples are : 1/2 , 3/ 4 , 5/6 ...
clearly , this does not necessarily define A , so option c is the odd one out
Answer: (-3, 4)
Step-by-step explanation: Given point coordinate (4,3).
We need to rotate the given point about 90º.
<em>In order to find the new coordinates of rotation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).</em>
Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.
In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.
On applying rule (h, k) ---> (-k,h), we get
(4,3) ---> (-3, 4)
