The answer is: D) 115
The explanation is shown below:
1. You have that the frequency with which a cricket chirps varies directly with the temperature, which you can express it as following:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
Where
is the frequency with which a cricket chirps,
is the temperature and
is the constant of proportionality.
2. If the cricket chirps 100 times per minute in 80° weather, you can calculate
as below:
![k=\frac{100}{80}=1.25](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B100%7D%7B80%7D%3D1.25)
3. Therefore, the frequency in 92° weather is:
![y=1.25x\\y=(1.25)(92)\\y=115](https://tex.z-dn.net/?f=y%3D1.25x%5C%5Cy%3D%281.25%29%2892%29%5C%5Cy%3D115)
Answer:
2014 price was $49,091
Step-by-step explanation:
I'm assuming you want to solve for 2014 year price...
2015 year price is 54,000 and was 10% higher than 2014 price, meaning 2015 price is 110% of 2014 price so...
p×110%=54,000
p=54,000/1.1
p=49,090.90
Hello back,
18=(x+y)/3
18=(x-y)*3/5
==>(x+y)/3=(x-y)*3/5
==> 5(x+y)=9(x-y)
==>5x+5y=9x-9y
==>4x=14y
==>x=7/2y
18=(7/2y+y)/3
==>9/2*y=18*3
==>y=12
==> x=7/2*12=42
Sorry for the error.
The sweater costs $12 because if the clock costs $18 you’ll minus 18 from 30 and get 12
