77.12 cm to the nearest hundredth.
Step-by-step explanation:
The length of the curved part = 1/2 * 2 pi r
= 15 pi.
Total perimeter = 30 + 15pi
= 30 + 15*3.1416
= 77.124.
Answer:
1) c=100
2) x^4-40x^3+400x^2

You're welcome :)
<em>We let...</em>
<em>x as the number of months he spent in Portugal</em>
<em>y as the number of months he spend in Brazil</em>
<em>From the problem, we can generate the following equations</em>
<em>x + y = 14</em>
<em>130x + 150y = 1920</em>
<em>Solving the equation gives us</em>
<em>x = 9 months in Portugal</em>
<em>y = 5 months in Brazil</em>
