The effective rate is calculated in the following way:

where r is the effective annual rate, i the interest rate, and n the number of compounding periods per year (for example, 12 for monthly compounding).
our compounding period is 2 since the bank pays us semiannually(two times per year) and our interest rate is 8%
so lets plug in numbers:
Answer: 27/12=2.25
Pretty simple:)
Step-by-step explanation:
The four interior angles of a quadrilateral always add to 360<span>°, so the answer is 98</span>
The factored form would be (3x-9)(x-1)
The picture should help a bit
Answer:
x = 75°
Step-by-step explanation:
Sum of angles in a triangle: 180°
So,
50°+55°+x=180°
105°+ x = 180°
Subtract 105° from both sides
x = 75°
