Answer: 67.5 cm
Step-by-step explanation:
Jason has 4 lengths of ropes
first is 
second is 
Third is ![0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}]](https://tex.z-dn.net/?f=0.3%5C%20m%5Capprox%2030%5C%20cm%5Cquad%20%5B%5Ctext%7B1%20m%20%3D%20100%20cm%7D%5D)
fourth is ![0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}]](https://tex.z-dn.net/?f=0.5%5C%20ft%5Capprox%206%5C%20in.%5Capprox%2015%5C%20cm%5Cquad%20%5B%5Ctext%7B1%20ft%3D12%20in.%7D%5D)
the total length of rope is the sum of four lengths

I believe the correct answer would be B. Down payment
Your welcome
It is: 180(n-2)
For example, the sum of the interior angles of a triangle is 180 degrees.
The quadrilateral can be cut into two triangle so the sum of the interior angles of a quadrilateral is 180*2=180*(4-2)
The pentagon can be cut into three triangle so the sum of the interior angles of a pentagon is: 180*3=180*(5-2)
The hexagon can be cut into four triangle so the sum of the interior angles of a hexagon is: 180*4=180*(6-2)
Answer:
5/9
Step-by-step explanation: If you find a common denominator ( i found 135 ) and you multiply each numerator by the number u multiplied the denominator to get the common denominator, you can see that 5/9 is greater. hope this helps and sorry if that was confusing
1. Take a look at the pictures attached.
2.
i) the first line divides the plane into 2 regions
ii) the second line adds 2 more regions so we have 4 in total.
iii) the third line adds 3 more regions, so 4+3=7 regions
iv) the fourth line adds 4 more regions.
so the

line adds n more regions to the ones created by the previous n-1 lines.
3.





So the recurrence relation is
