Answer:
2/5 m or 4 dm
Step-by-step explanation:
The fraction 4/10 can be reduced by removing a factor of 2 from numerator and denominator. The length could be expressed as 2/5 m.
The metric system has unit prefixes that make it easy to choose appropriate units for almost any measurement. Apparently Christina wants to use 1/10 m as her unit of measurement. That length is also called a "decimeter." So, Christina's measurement could be expressed in very simple form as 4 dm.
_____
A decimeter is not a particularly common unit in everyday use, though it is reasonably useful for many purposes.* More conventionally, lengths in that range are expressed in centimeters, so Christina's measurement could also be described as 40 cm.
____
* I like units of decimeters for volume calculations, because a cubic decimeter is 1 liter.
Answer:
About 473 quails.
![P=175(1.22)^t](https://tex.z-dn.net/?f=P%3D175%281.22%29%5Et)
Step-by-step explanation:
Exponential equation with
as the initial amount and rate of r is:
![P=P_0(1+r)^t](https://tex.z-dn.net/?f=P%3DP_0%281%2Br%29%5Et)
![P=175(1+.22)^t](https://tex.z-dn.net/?f=P%3D175%281%2B.22%29%5Et)
![P=175(1.22)^t](https://tex.z-dn.net/?f=P%3D175%281.22%29%5Et)
After 5 years the population will be:
![P=175(1.22)^5](https://tex.z-dn.net/?f=P%3D175%281.22%29%5E5)
![P \approx 472.9739](https://tex.z-dn.net/?f=P%20%5Capprox%20472.9739)
So the population will be about 473 quails.
