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.
Think of it this way. Ignore for now that $100 was stolen.
The purchase of the $70 item for $100 cash with $30 change is a perfectly fair purchase. The store received $100 cash, and the store gave $70 worth of merchandise plus $30 cash.There was no loss to the store there.
The fact that $100 in cash was stolen earlier from cash register means the loss is $100. The legitimate transaction does not affect the loss.
If you have a hard time understanding the loss is $100, then think of it this way.
Reverse the order of the two happenings.
A person walked into a store and bought a $70 item with a $100 bill. He received $30 change. So far, there is no loss to the store. Everything is legit.
That customer later came back to the store and stole $100 from the cash register.
Here we see clearly that the loss is exactly $100. It is simply the $100 stolen from the cash register.
The answer is A
its a simple eqaution carry the 1 over
Figure #5 shows 5 squares which I would assume means (5, 5)
In the table you have the point (3, 7)
From this you can find the slope: (7 - 5)/(3 - 5) = -1
Completions of table:
x y
0 10
1 9
2 8
3 7
4 6
5 5
6 4
Rule/Equation:
y = -x + 10

Step-by-step explanation:
log(x+2)-log(x-1)=log2
log(x+2)/(x-1)=log2
=> (x+2)=2(x-1)
=>x+2 =2x-2
=> x=4
