Here is your answer:
30% of 50=45
Your answer is 45 because...
150/x=100/30
(150/x)*x=(100/30)*x
150=3.33333333333*x
(3.33333333333) to get x
150/3.33333333333=x
45=x
x=45
Your answer is...
x=45
Answer:
There are 102 coins total:
34 Quarters
20 loonies
48 toonies
Step-by-step explanation:
Assuming money is counted in coins instead of value, it can be solved like this.
1. find a common denominator for 1/3 and 1/5. We can use 15. So, of the money collected, 5/15 were quarters and 3/15 were loonies. This makes 7/15 toonies. If there are 48 toonies, we can divide this by 7 to find the value of 1/15. 48/7 = 6 6/7. Multiply this number by 15 (for each value) and you get 102 6/7.
There are 102 coins total:
34 Quarters
20 loonies
48 toonies
When you factor (x^2-4x-5), you get (x+1)(x-5).

Step-by-step explanation:
This question requires a list of options.
Since, there are none; I'll give a general explanation to answer this.
We have that:
The general format of an equation in terms of f and c is:
Where
and
A true statement about the function above is:
The slope of the equation is 14
This means that at every minute, there's an additional 14 chirps from the cricket.
Another true statement about the function is that:
The y intercept is 40.
This means that the initial number of chirps by the cricket is 40
i.e. At time, c = 0 minutes.
There are 40 chirps.
A likely question could be to determine the number of chirps in (say) 5 minutes.
This means that:
Substitute 5 for c in
This implies there are 110 chirps in 5 minutes
