Answer:
![\frac{7}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B5%7D)
Step-by-step explanation:
You can make 1.4 as a fraction, and it will be the same but in a different form.
So, to make a decimal by a fraction, you make 1.4 into a whole number. 1.4 will be 14.
Now, the denominator will be 10.
So, when you simplify
, which is ![\frac{7}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B5%7D)
Answer:
The maximum height of the prism is ![12\ m](https://tex.z-dn.net/?f=12%5C%20m)
Step-by-step explanation:
Let
x------> the height of the prism
we know that
the area of the rectangular base of the prism is equal to
![A=L*W](https://tex.z-dn.net/?f=A%3DL%2AW)
![A\leq 27\ m^{2}](https://tex.z-dn.net/?f=A%5Cleq%2027%5C%20m%5E%7B2%7D)
so
-------> inequality A
------> equation B
-----> equation C
Substitute equation B in equation C
![L=(x-9)+6](https://tex.z-dn.net/?f=L%3D%28x-9%29%2B6)
------> equation D
Substitute equation B and equation D in the inequality A
-------> using a graphing tool to solve the inequality
The solution for x is the interval---------->![[0,12]](https://tex.z-dn.net/?f=%5B0%2C12%5D)
see the attached figure
but remember that
The width of the base must be
meters less than the height of the prism
so
the solution for x is the interval ------> ![(9,12]](https://tex.z-dn.net/?f=%289%2C12%5D)
The maximum height of the prism is ![12\ m](https://tex.z-dn.net/?f=12%5C%20m)

I think its A
Step-by-step explanation:
Answer:
28.3 cm
Step-by-step explanation:
The formula to find the circumference is 2•π•radius. The diameter is 9 cm, so the radius is 9/2 = 4.5 cm. So, the circumference is:
2•4.5•3.14 = 28.26 ≈ 28.3 cm
