Viktor [21]

Answer: The mean is 9 cups, the median is 6 cups, and the total is 27.

Step-by-step explanation:

To calculate the mean, add up all values and divide by the amount of all the values: 3 + 6 + 18 = 27, 27/3 = 9. The median is the middle number, which is 6 in the set 3, 6, 18 (least to greatest). Finally the total is already 27. Hope this helps, please consider Brainliest (click on the crown).

The formula=A+2lh+2wh gives surface area a. Of a rectangler solid with length, width, and height, L,W, and H, respectively solve

iogann1982 [59]

Answer:

$l= \frac{A}{2h} -w$

Step-by-step explanation:

The question is not correct (particularly the expression for the area)

A=2lh+2wh

Now we are expected to solve for l, that is we are going to make l subject of the formula, we have

let us take the second term on the RHS to the LHS

$A-2wh= 2lh$

we can now divide both sides by 2h we have

$\frac{A-2wh}{2h} = l\\\\l=\frac{A}{2h} -\frac{2wh}{2h} \\\\l= \frac{A}{2h} -w$

hence the expression for the length is $l= \frac{A}{2h} -w$
