The answer to r is going to be the lucky number 5
That would be the number of permutations of 3 from 10.

Answer:
79°
Step-by-step explanation:
A triangle has 180° in it so 180 - 82 =98- 19=79
Answer:
30 yards for 24 vs 1 foot for 25 cents
so lets multiple the yards by 3 to see how many feet
90 feet = 30 yards
90 feet 24 dollars
now lets divide 90 by 24
3.75 so 3.75 per foot
so the second one is way better
Hope This Helps!!!
