Answer:
$6370
Explanation:
The simple interest formula gives us the final amount A given the principal amount P:

where r is the interest rate and t is the time interval.
Now in our case we have
P = 2800
r = 4.25/100
t = 30 years
therefore, the above formula gives

which simplifies to give

Hence, the account balance after 30 years will be $6370.
Answer:
The answers are as follows: 12 106 42
Step-by-step explanation:
Given:
Using BODMAS rule (Bracket, Of, Division, Multiplication, Addition and Subtraction) we would calculate
separately and
separately and add them. So we have
.
Now for the second question:
. we would get
Next,
. This could be written as:
. Hence the answers.
Well, we see that it is a straight line
so the derivitive would be perpendicular
5/4 times what=-1
-4/5
the slope is -4/5
Answer:
1/4 feet long should each pieces be.
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour
As per the statement: Becky has a board that is 2 and 3/4 feet long.
⇒ Length of a board =
feet
Also, she need to cut the board into 11 pieces.
by unit rate definition:

or

Therefore, 1/4 feet long should each pieces be.
