Answer:
2) (12 ÷ 3) +5
3) .483
Step-by-step explanation:
You want to calculate the interest on $30000.00 at 6% interest per year after 20 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $30000.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 20....year(s) time periods.
So, t is 20....year time periods.
To find the simple interest, we multiply 30000 × 0.06 × 20 to get that: The interest is: $36000.00
Usually now, the interest is added onto the principal to figure some new amount after 20 year(s),
or 30000.00 + 36000.00 = 66000.00. For example:
If you borrowed the $30000.00, you would now owe $66000.00
If you loaned someone $30000.00, you would now be due $66000.00
If owned something, like a $30000.00 bond, it would be worth $66000.00 now.
<u>Answer:</u>
D. |–c| = 3 and –|d| = 4
<u>Step-by-step explanation:</u>
We are given these values of two variables and asked which of the statements in the given options is true:
c = –3 and d = 4
In mathematics, we know that the absolute value or modulus of a real number x is the non-negative value of x despite of whatever sign it has, positive or negative.
Therefore, the modulus of c |–c| = 3 and modulus of –|d| = 4 so option D is the correct one.
Answer:
Cup 1 acts as a control group.
Step-by-step explanation:
Control group: The group used in the experiment by the researchers in which no change in the variable is done. It is then set as a benchmark for the groups which are being tested.
We are given 4 groups which are being experimented for the flotation of an egg in water.
Since in Cup 1, there is no addition of salt
So, there is no change in the variables.
So, by definition of control group .
So, cup 1 acts as a control group since there is no change in the variable .
Hence, the correct answer is Option 1.
Cup 1 acts as a control group.
