Plug in r and get: 5(3+7)-2(3)=44
Answer:
L=135 W=105
Step-by-step explanation:
Your rectangle has two length sides and two width sides. That means two sides are 30 feet longer than the other sides. If you subtract 60 from 480, you get 420. Divide 420 by 4 and you get 105. So now you know the width sides are 105 feet long, so 105+105=210. Now all you have to do is add 30 to 105 and get 135. That is the length of the two longer sides. So add 135 and 135 to get 270. All you have to do is add 210 and 270 and you end up with the 480 feet of fence you were given. I know this is probably not the fancy way of doing it, but it works.
For the answer to the question above asking what was the amount of the withdraw if <span>Doris put $4000 in a 2-year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money?</span>
First year Interest: I(1) = 4000[(1.005)^12 - 1] = 246.71 = penalty for early withdrawal
Value after two years: P(2) = 4000(1.005)^24 = 4508.64
Value after 2 years with penalty: V = 4000(1.005^24 - 1.005^12 + 1) = $4261.93
Answer:
Step-by-step explanation:
Answer:
123.5 m^2
Step-by-step explanation:
The area of the whole rectangle is 9 x 19 = 171 m^2
The area of the region that isn't shaded is (5 x 19)/2 = 47.5 m^2 because the height of the triangle is 5 (9 - 4) and the area of a triangle is
(height x length)/2
171 - 47.5 = 123.5 m^2
