Answer:
10 000
Step-by-step explanation:
For each choice of the first two digits you have 10 choices for the third digit. Thus you have 10x10x10 = 1000 choices for the first three digits. Finally you have 10 choices for the fourth digit and thus there are 10x10x10x10 = 10 000 possible 4 digit combinations from 0-9.
Answer:
r = -1/2
Step-by-step explanation:
To find r, divide any number in the set by the previous number in the set and reduce the fraction if possible. Check multiple numbers to make sure r is consistent between all entries...
-200/400 = -1/2
100/-200 = -1/2
-50/100 = -1/2
So r = -1/2
Add 8/15. The answer is d
86 × π = 86π
or
86 × 3.14 = 270.04
you can use both of them depends on what form the question is asking that ur answer be in
