The volume of a medal is 35 cm³
ratelena [41]

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>

Is 1/2 between 0.1 and 0.2?
Nady [450]
No, 1/2=0.5


This is because half of one is 0.5, since 0.5 x 2 = 1.

0.1 written as a fraction would be 1/10, since 0.1 x 10 = 1.
0.2 written as a fraction would be 1/5, since 0.2 x 5 = 2
