Answer:
342 grams of sugar are needed.
Step-by-step explanation:
This really should be in chemistry. Math types may not know any chemistry.
Step One
Find the number of moles needed in a solution of the givens.
<em><u>Givens</u></em>
V = 2.00 L
C = 0.500 moles / Liter
<em><u>Formula</u></em>
n = C * V
<em><u>Sub and Solve</u></em>
n = 2 * 0.5 = 1 mole
Since you need just 1 mole, the answer is 342 grams of sugar are needed to put into a solution of 2 Liters with a concentration of 0.500
The answer is to 3 decimal places so 342 is the answer.

Answer:
- sides: 12 feet
- front: 28 feet
Step-by-step explanation:
Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...
P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle
80 = 2(x + (2x+4)) . . . . . with values from the problem filled in
40 = 3x +4 . . . . . . . . divide by 2, collect terms
36 = 3x . . . . . . . . . subtract 4
12 = x . . . . . . . . . divide by 3. This is the length of the side fence.
2x +4 = 2(12) +4 = 28
The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)
Okay, I'm pretty sure the answers are:
11) B
12) C
13) B
14) A
