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>
You can do
83 - 5 to find the answer
So that's
78 or
5 + 78 = 83
Basically you multiply like normal and then add in the decimal point (to figure out where it goes count how many numbers are behind the decimal (in this case 2) and then count that many places from the right into your answer and that's where it goes). So here 374 x22 =8228 but when you add in the decimal you get 82.28 :)
