2 now help me :(
Since your probably solving for W, isolate W by adding the -3n to both sides and get W=5n now use a calculator and multiply 5 and Pi. To Get 15.7.
I used N for pi since I don’t have that symbol
You need to specify what needs to be solved so I just assumed W
Answer:
Step-by-step explanation:
Firstly, we will use the formula π × d
Which will be 22\7 × 28 (this is the radius multiplied by 2)
After multiplying you will get 88 cm as your perimeter
=88 cm
Answer:
C.$4,300
Step-by-step explanation:
We are given that
Cost of truck=$19,000
Depreciation per year=$21,00
We have to find the salvage value.
Let salvage value=x
Formula:Depreciation per year=![\frac{C.P-salvage\;value}{number\;of\;years}](https://tex.z-dn.net/?f=%5Cfrac%7BC.P-salvage%5C%3Bvalue%7D%7Bnumber%5C%3Bof%5C%3Byears%7D)
Using the formula
Substitute the values then we get
![2100=\frac{19000-x}{7}](https://tex.z-dn.net/?f=2100%3D%5Cfrac%7B19000-x%7D%7B7%7D)
![2100\times 7=19000-x](https://tex.z-dn.net/?f=2100%5Ctimes%207%3D19000-x)
![14700=19000-x](https://tex.z-dn.net/?f=14700%3D19000-x)
![x=19000-14700](https://tex.z-dn.net/?f=x%3D19000-14700)
![x=4300](https://tex.z-dn.net/?f=x%3D4300)
Hence, the salvage value=$4,300
