Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5
Answer:
B. 10 in.
Step-by-step explanation:
When you do length times width times height 10*10*10 equals 1000
10*10=100 and 100*10=1000
If you're asking for the final term, the solution is to take b(from ax^2+bx+c), half it, and then square it. So in this case, b is 8.
8/2=4
4^2=16
So:
v^2+8v+16
If you factor it, it becomes (v+4)^2, which shows that its a perfect square.
Given:
Matthew's bank lent him $8,000 for four years at an interest rate of 6 percent, compounded annually.
To Find:
The total amount that Matthew's bank will receive after 4 years.
Answer:
The total amount the bank will receive after 4 years is $10,099.8
Step-by-step explanation:
The principal amount 'P' lent to Matthew is $8000
The time period 't' is 4 years
The lending rate 'r' is 6%
As the interest is compounded annually, we use the Compound Interest formula to calculate the amount the bank will receive 'A' after 4 years.
The formula we use is

Thus, the total amount the bank will receive after 4 years is $10,099.8
