1. Draw two arcs with the same radius at point A and B.
2. Join the intersection points C and D (see picture). The line CD bisects arc AB into two equal parts.
3. The point S of intersection of arc AB and line CD is a middlepoint of the arc AB.
Combine like terms.
3a + 2a = 5a
5a - 2b.
Plug in the values for a and b.
5(2) - 2(3)
10 - 6 = 4
Answer is B.
Answer:
Simple Interest: A = P(1+rt)
Step-by-step explanation:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Ex1: If $1000 is invested now with a simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
