The sum of y+x, or 5+7, is rational. This is because each integer(non fraction/decimal)is rational, it is also rational.
Answer:
169 sq cm
Step-by-step explanation:
Answer and explain:
1st person: 70 % throws
70/100x80 = 56 out of 80 throws
2nd person: 60% throws
60/100x80 = 48 out of 80 throws
3rd person 50% throws
50/100x80 = 40 out of 80 throws
56+48+40/80x3 = 77/120
One equation that gives the estimated number of free throws (all the 3 people) is 77 out of 120. The best player will make about 56 out of 80 free throws.
If you estimated 3.7 to 4 and 5.1 to 5 the answer would be 20. You would have 20 and now you can think is 20 a reasonable answer for 3.7x5.1. The answer for 3.7x5.1=18.87, so the answer is yes.
Hope that helped:)
