Answer:
see explanation
Step-by-step explanation:
given that r varies jointly with x and y then the equation relating them is
r = kxy ← k is the constant of variation
To find k use the condition r = 15 when x = 3 and y = 4
k =
=
= 1.25
r = 1.25xy ← equation of variation
When x = 16 and y = 1.25, then
r = 1.25 × 16 × 1.25 = 25

Step-by-step explanation:
this is basic math just use multiplication i think u typed the problem whrong
If two triangles are similar, that means their side lengths are proportional.
Now we want to find side PQ, so let us set up some proportions:

So x = 30.
Hope that helps!
3(X)+X=190000 is how you'd find the answer the answer is 47,500
