C=<span>1 is the answer my good man have a good day :)</span>
Answer:
≈ 11.78 in
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr ×
( cancel 2π on numerator/ denominator )
= 15 × ![\frac{\pi }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20%7D%7B4%7D)
= ![\frac{15\pi }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B15%5Cpi%20%7D%7B4%7D)
≈ 11.78 in ( to 2 dec. places )
I believe it should be 1.4 since the answer you get is 1.4112903226... you would round but on the tenths place 1.4
Answer:
Equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Step-by-step explanation:
The distributive property says that:
![a \cdot (b+c) = a\cdot b + a\cdot c](https://tex.z-dn.net/?f=a%20%5Ccdot%20%28b%2Bc%29%20%3D%20a%5Ccdot%20b%20%2B%20a%5Ccdot%20c)
Given the expression: ![9(2a+1)](https://tex.z-dn.net/?f=9%282a%2B1%29)
Apply the distributive property:
![9 \cdot (2a) +9 \cdot 1](https://tex.z-dn.net/?f=9%20%5Ccdot%20%282a%29%20%2B9%20%5Ccdot%201)
Simplify:
![18a+9](https://tex.z-dn.net/?f=18a%2B9)
Therefore, the equivalent expression of
is, ![18a+9](https://tex.z-dn.net/?f=18a%2B9)
