Two metal disks, one made of silver and one made of copper, have the same volume. The densities for silver and copper are listed below. • Silver: 10,490 kg/m2
• Copper 8,940 kg/m3
The silver disk has a mass of 30 grams. Which is closest to the mass of the copper disk?
A 15.5
B. 25.6
c. 35.2
D. 19.4

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
