Hello :
the area is : A=<span>πr²
</span> π ≃ 3.14 r : <span>ridus
</span> <span>diameter = 2 r
</span>r = 18/2= 9 ft
A=3.14×9² = 254.34 ft²
Answer:
Option (2)
Step-by-step explanation:
Given expression is ![\sqrt[3]{64a^6b^7c^9}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64a%5E6b%5E7c%5E9%7D)
By simplifying this expression,
![\sqrt[3]{64a^6b^7c^9}=\sqrt[3]{(4)^3(a^2)^3(b^2)^3(b)(c^3)^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64a%5E6b%5E7c%5E9%7D%3D%5Csqrt%5B3%5D%7B%284%29%5E3%28a%5E2%29%5E3%28b%5E2%29%5E3%28b%29%28c%5E3%29%5E3%7D)
![=(4a^2b^2c^3)\sqrt[3]{b}](https://tex.z-dn.net/?f=%3D%284a%5E2b%5E2c%5E3%29%5Csqrt%5B3%5D%7Bb%7D)
Option (1)
![2abc^2\sqrt[3]{4a^2b^3c}](https://tex.z-dn.net/?f=2abc%5E2%5Csqrt%5B3%5D%7B4a%5E2b%5E3c%7D)
= ![2ab^2c^2\sqrt[3]{a^2c}](https://tex.z-dn.net/?f=2ab%5E2c%5E2%5Csqrt%5B3%5D%7Ba%5E2c%7D)
Option (2)
![4a^2b^2c^3(\sqrt[3]{b})](https://tex.z-dn.net/?f=4a%5E2b%5E2c%5E3%28%5Csqrt%5B3%5D%7Bb%7D%29)
[Fully simplified form]
Option (3)
![8a^3b^3c^4(\sqrt[3]{bc} )](https://tex.z-dn.net/?f=8a%5E3b%5E3c%5E4%28%5Csqrt%5B3%5D%7Bbc%7D%20%29)
[Fully simplified form]
Option (4)
![8a^2b^2c^3(\sqrt[3]{b})](https://tex.z-dn.net/?f=8a%5E2b%5E2c%5E3%28%5Csqrt%5B3%5D%7Bb%7D%29)
Expression given in Option (2) is equivalent to the given expression.
Option (2) will be the answer.
Answer:
50 teachers
Step-by-step explanation:
step 1
Find the number of teachers for a ratio of 1:12
1/12=x/2,400
x=2,400/12=200 teachers
step 2
Find the number of teachers for a ratio of 5:48
5/48=x/2,400
x=2,400*5/48=250 teachers
step 3
Find the difference
250-200=50 teachers
