Answer:
There are 24 dimes
Step-by-step explanation:
we can make an equation and then solve it to find our answer.
n = number of nickles at $0.05 each
4d = number of dimes at $0.10 each
(0.5)n + (0.10)(4n) = 5.40
We now solve this
First, multiply
0.5d+0.4d=5.40
then add
0.9d=5.40
then divide
D=6
Then, multiply by four since there are four times as many dimes
6x4=24
There are 24 dimes

Answer:
As*Nc/Ns
Step-by-step explanation:
The square has Ns discrete points. The points are quite large and are close around each other
As = Area of square
Nc = number of points inside square
Ns = total number of points inside square
Ac = area of circle
Such that
Nc/Ns = Ac/As
We cross multiply
AcNs = NcAs
Dividing through by Ns will give:
Ac = NcAs/Na
Which Is also
= As *Nc/Na
