Answer:
301.224 g
Step-by-step explanation:
Let's divide in the ratio 21:4 the volume of the medal (35cm^3)
copper = (21/25)(35cm^3) = 29.4cm^3
tin = (35 - 29.4)cm^3 = 5.6cm^3
<em>FOR THE COPPER</em>
8.84 : 1 = X : 29.4
X = 259.896(g)
<em>FOR THE TIN</em>
7.38 : 1 = X : 5.6
X = 41.328(g)
<em>(259.896 + 41.328)g </em><em>=</em><em> 301.224 g</em>
I solved and the mean is 10
Divide the numerator and denominator by their gcf (25)
75/25= 3
100/25= 4
Final answer: 3/4
