First you need to find how many grams is 1 ounce. 1o z.is 28.35 g, then you need to multiply 28.35 g by 5 which is 141.75. you need to round it to the nearest hundred so it is about 142 grams.
the key here would be
1 oz. = 28.35g or 1 oz. = 28 g
When u all those 5 numbers together u get 354 so:
354/5= 70.8
70.8 is ur median
So if seven is 7, and its 7+k=blah blah blahAnd the first number there was is 7.5 so k+7=7.5 k is 0.5
Use Pythagorean theorem
a^2 + b^2 = c^2
C = hypothenuse
8^2 + b^2 = 15^2
64 + b^2 = 225
b^2 = 161
b = square root 161 = 12.68
Solution: 12.7 cm
