Let the amount of the first brand be x, and let the amount of the second brand be y.
0.09x + 0.14y = 240 * 0.13 .................(1)
x + y = 240 ..............(2)
y = 240 - x .......................(3)
Plugging the value for y from equation (3) into equation (1), we get:

...............(4)
Equation (4) simplifies to:
-0.05x = -2.4
giving the value for the required amount of 9% vinegar as 48 ml and the required amount of 14% vinegar as 240 - 48 = 192 ml.
Answer: 2 x2=4 or 2x-2=-4
Step-by-step explanation: its simple math
The solid shape is a cone and a half sphere. So the equation would be (cone volume) + (1/2 sphere volume):

If the volume of the cone is 270pi and the height of the cone is 10, then:

The radius of the object is 9 cm. Therefore, we can plug into the formula for the total volume:

The total volume is 513 pi cm^3

First part, in quadrilateral WXYZ, WX is parallel to ZY because both sides are equal while the other parallel segments WZ and XY are equal but different side lengths.
The measure of angle Z is 78 because both of the pictures are the same, only rotated. and angle S and Z are acute.
