Answer:
Length of mammoth's tusk in poster = 15.33
Explanation:
Actual height of mammoth = 10 feet 5 inches = 126 inches
Height on the poster of mammoth = 14 inches
Actual length of mammoth's tusk = 11.5 feet = 138 inches
Length of mammoth's tusk in poster = x
126 : 14 :: 138 : x
Product of mean = product of extremes
x * 126 = 14 * 138
![x = (14*138)/(126)](https://img.qammunity.org/2022/formulas/mathematics/college/ui1vee8rr1flzr14cn1ye0vm1zpikw1pef.png)
