The curtains will be 152 cm or 1.52 m.
There are 100 cm in a meter. Therefore, 1.6 meters is equal to 160 cm. If we subtract 8 from 160, we have 152 cm. We can also write it as 1.52 m.
Factor out 18.
The factors for 18 are as listed:
1, 2, 3, 6, 9, 18
Now factor out 30.
The factors for 30 are as listed:
1, 2, 3, 5, 6, 10, 15, 30
Now look at the factors that are both factors for 18 and 30.
So, the common factors are 2, 3, and 6.
0.50 because if you turn 15% into a decimal you get 0.15 and 0.65-0.15 =0.5
Alright, so there are 4 reindeer to fill 3 different positions, which is a permutation. If you have a calculator, this can be calculated by finding the nPr function and filling in 4P3 (4 pick 3).
If you don't have a calculator, you can use the formula:
n! / ((n-r)!)
where n is the total number in the set and r is the number chosen
solving that formula:
4! / (4-3)! = 4*3*2*1/1 = 24
Either way, you get the answer of 24.
Answer: The answer should be 164,340.
