Answer:
Ratios are proportional when the numbers in the ratio are multiply or divide by the same number. Ex. 3:5 = 6:10 = 12:20 = 9:15 (cross multiply the fractions and the results are the same 3/5 = 6/10)
Step-by-step explanation:
Number of trees that are grew more than 3 feet = 10 + 35 = 45
Number of trees that grew more than 3 feet and is more than 50 yards away = 35
P(3 feet and more than 50 yards) = 35/45 = 7/9
Answer: 7/9
Step-by-step explanation:
log(7·x + 7) = 1
7·x + 7 = 10^1
7·x = 10 - 7
x = 3/7 = 0.4285714285
Multiply 12 by 4%, or 4/100, and 4/100 simplifies to 1/25. 12/1 x 1/25 = (12 x 1)/(1 x 25) = 12/25, which equals 0.48. So, the smallest frog is 0.48 inches long, but can be rounded to 0.5 inches long.
