Answer:
AFB
Step-by-step explanation:
6 bills in the deposit were $10 bills.
<u>Step-by-step explanation:</u>
The total number of bills he gave the teller = 24 bills
x + y = 24 ------------(1)
Let,
x be the number of $5 bills.
y be the number of $10 bills.
The total bank deposit made using $5 and $10 bills are $150.
<u>He deposits $5 bills and $10 bills. So, the equation can be framed as :
</u>
5x + 10y = 150 --------(2)
The question is asked for how many $10 bills were in the deposit,
Here 'y' is the number of $10 bills.
<u>To solve for y value :
</u>
The eq(1) must be multiplied by 5 and subtract eq(2) from eq(1),
5x + 5y = 120
-(<u>5x + 10y = 150</u>)
<u>-5y = -30 </u>
⇒ y = 30/5
⇒ y = 6
Therefore, there were 6 bills in the deposit that are $10 bills.
An acre is a surface measure, used in agriculture in several countries.
According to the country and the time, it is equivalent to several surfaces.
We will use the following conversion:
1 acre = 43560 feet ^ 2
Thus:
40 acre = 1,742,400 feet ^ 2
The area of the rectangle is:
1,742,400 = (1,200) * (x)
Clearing the other dimension we have:
x = (1742400) / (1200)
x = 1452 feet
Answer:
He needs 1452 feet of fence.
