There are two parts in the given collection. One contains quarters and other contains dimes.
Let's compare the whole coin collection to the quarters.
One way to represent the ratio is 15 : 7.
The other way is ![\frac{15}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B7%7D)
C, it has the ratio of $9 per hour which is a greater ration than all the other options.
Hope this helps!
You remember from SOH CAH TOA that
.. Cos = Adjacent/Hypotenuse
.. cos(C) = 80/82 = 40/41 . . . . . . . . . . . seems to match the last selection
The answer is 40 you do 10 times 4 I hope it helped you you only need to multiply
Answer:
If you are reffering to GCF then the GCF would be explained like this
Find the prime factorization of 18
18 = 2 × 3 × 3
Find the prime factorization of 60
60 = 2 × 2 × 3 × 5
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 3
GCF = 6
