Put first on about 1 and a third and second on exactly 3.
Hope this helps.
Let cost of Emma's phone = x
Given that cost of Sophie's phone = 640
Then ratio of their phones cost will be x:640 or x/640
Given that ratio of their phones cost is 7:8 or 7/8
So both ratios will be equal.
x=560
So the new ratio of the cost of their phones will be 560:640
Now we have to find about how much should the prices of their phones decrease in order to have a ratio of 9:11.
So let that decreased amount is k then we will get equation :
11(560-k)=9(640-k)
6160-11k=5760-9k
6160-5760=11k-9k
400=2k
200=k
Hence final answer is prices of their phones should decrease by 200 in order to have a ratio of 9:11.

24.50 divided by 5 is 4.9
<span>If approximately 2.3 million people die per year in the US, this is equivalent to deaths per minute. Round to the nearest hundredth.
of minutes in a year
365*24*60
of deaths per minute = 2.3x10^6/(365*24*60) = 4.38 deaths/minute</span>
Answer:
A)
Step-by-step explanation:
Since we are given the function, we can simply plug in the x as 9. So we get 50(0.952)9. Solving this, we get 450(.952) and this is about 428. SO our answer is a) about 428 feral cats.
