Answer:
15.10 km
Step-by-step explanation:
All you would have to do is add 5 km every time you add 1 cm. Then for the .5 you would divide 5 by .5 to get the second part of the answer.

I got it wrong I'm sorry!
Answer:
1.22%
Step-by-step explanation:
150 x 1.22 = 183
Percentages are really just fractions out of 100. So 45% is really just 45/100. If you want to find the lowest fractions, you have to break each number up into prime factors and see which overlap. So:
45 = 9x5
= 3 x 3 x 5
100 = 2 x 50
= 2 x 5 x 10
= 2 x 5 x 2 x 5
So 45/100 = 3x3x5/2x2x5x5
Now because there's a 5 on both sides, we can cancel down. If we do, that leaves us with
3x3/2x2x5
Which is 9/20
For part A, there are 4 equal lengths put together and the sum of them is 36. So dividing 36/4 gives us 9.
So the length of each edge is <u>9 cm</u>!
For part B, finding surface area means the total area of the cube on its six faces.
So for one face of the cube, the area is
9 × 9 = 81 cm^2
There are 6 faces so we multiply 81 by 6 and get 486 cm^2.
Hope this helps!
