Okay a ton is 2000 pounds i think you divide it 1/4
and that is it is 8000 i think
The correct answer is d. 9 + 0 = 9
Further explanation:
If x is an element of a set, and adding a number to it doesn't change it i.e. the result is also x then the number is called additive identity.
In mathematics, 0 is considered as additive identity because no matter with which number it is added, the number always remains same.
In the given options:
Option a. 5*1=5 demonstrates multiplicative identity
Option b. 3+5=5+3 demonstrates commutative property
Option c. 4+ (6 + 8) = (4+6) +8 demonstrates associative property
While the last option
d. 9 + 0 = 9 demonstrates additive identity as zero is being added to 9 and the answer is also 9.
The correct answer is d. 9 + 0 = 9

Answer:
99 degrees
Step-by-step explanation:
angle 8 = 99 degrees because corresponding or 'f shaped' angles are equal
Answer:
[4,5]
Step-by-step explanation:

25123.5325 square feet of tin is needed to make the roof
<em><u>Solution:</u></em>
Given that the roof of a farm silo is the shape of a hemisphere and is made of sheet tin
Given diameter of silo = 126.5 feet
![Radius = \frac{diameter}{2}](https://tex.z-dn.net/?f=Radius%20%3D%20%5Cfrac%7Bdiameter%7D%7B2%7D)
![r = \frac{126.5}{2} = 63.25](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B126.5%7D%7B2%7D%20%3D%2063.25)
<em><u>To find: sheet tin is needed to make the roof</u></em>
So we have to find the curved surface area of hemisphere
The curved surface area of hemisphere is given as:
![\text{ curved surface area } = 2 \pi r^2](https://tex.z-dn.net/?f=%5Ctext%7B%20curved%20surface%20area%20%7D%20%3D%202%20%5Cpi%20r%5E2)
Substitute r = 63.25 in above formula
![\text{ curved surface area } = 2 \times 3.14 \times (63.25)^2\\\\\text{ curved surface area } = 6.28 \times 4000.5625\\\\\text{ curved surface area } = 25123.5325](https://tex.z-dn.net/?f=%5Ctext%7B%20curved%20surface%20area%20%7D%20%3D%202%20%5Ctimes%203.14%20%5Ctimes%20%2863.25%29%5E2%5C%5C%5C%5C%5Ctext%7B%20curved%20surface%20area%20%7D%20%3D%206.28%20%5Ctimes%204000.5625%5C%5C%5C%5C%5Ctext%7B%20curved%20surface%20area%20%7D%20%3D%2025123.5325)
Thus 25123.5325 square feet of tin is needed to make the roof
