Answer:
7.
Step-by-step explanation:
21 = 3 * 7
28 = 2 * 2 * 7
42 = 2 * 3 * 7
Collecting common factors:
t is common to all 3 sets of factors so
HCF = 7.
Explanatory variable = independent variable = r

Answer:
$351.00
Step-by-step explanation:
P is the principal amount, $900.00.
r is the interest rate, 3.00% per year, or in decimal form, 3.00/100=0.03.
t is the time involved, 13....year time periods.
So, t is 13....year time periods.
To find the simple interest, we multiply 900 × 0.03 × 13 to get the the answer.
Cheers mate!
