Answer:
Length of mammoth's tusk in poster = 15.33
Step-by-step 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 = 15.33

Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
Step-by-step explanation:
Let,
Weight of one large bead = x
Weight of one small bead = y
According to given statement;
12x+8y=88 Eqn 1
5x+2y=25 Eqn 2
Multiplying Eqn 2 by 4
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 8
Putting x=1.5 in Eqn 1
Dividing both sides by 8
Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
