Answer:
d) 1.25 g
Step-by-step explanation:
If it has a half life of 40 days, there will be 5 half-lives in that span of time so if you divide 40 by 2, 5 times or just
, it will equal 1.25.
![\frac{40}{2}=20\\](https://tex.z-dn.net/?f=%5Cfrac%7B40%7D%7B2%7D%3D20%5C%5C)
![\frac{20}{2} =10](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B2%7D%20%3D10)
![\frac{10}{2} =5](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B2%7D%20%3D5)
![\frac{5}{2} =2.5\\](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%20%3D2.5%5C%5C)
![\frac{2.5}{2} =1.25](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%7D%7B2%7D%20%3D1.25)
Answer:
The area of this composite figure is 122.75 m².
Step-by-step explanation:
What I can go on ahead & do is split this figure into a 5 * 16 rectangle and a 9 by 9.5 triangle.
(5 * 16) + 1/2(9 * 9.5) <em>{Multiply 5 by 16 first; go from left to right}</em>
80 + 1/2(9 * 9.5) <em>{Now multiply 9 by 9.5}</em>
80 + 1/2(85.5) <em>{Then multiply 85.5 by 1/2, which is the same thing as dividing by 2}</em>
80 + 42.75 <em>{Lastly, add the two values together}</em>
122.75 m²
The area of this composite figure is 122.75 m².
