The answers are
1: False
2: True
3: True
4: False
Answer:
72 cubic ft
Step-by-step explanation:
To find volume you multiply length × width × height
Length is 4, width is 6 and height is 3
4×6×3= 72
900x300=270,000 plus 2 would equal 270,002.4 devided by 3-2001 would equal 87,999.8
The answer will be B because all three angles of the triangles add up to180 degrees, and we already know the total of two other angles are 100 degrees, which made the unknown angles have 80 degrees. Hope it help!
From the given information, a exists jointly proportional to b and c.
then ![$$a \propto b c$](https://tex.z-dn.net/?f=%24%24a%20%5Cpropto%20b%20c%24)
Therefore, the value of a exists 2.

What is the value of a?</h3>
Given, a exists jointly proportional to b and c.
![$$a \propto b c$](https://tex.z-dn.net/?f=%24%24a%20%5Cpropto%20b%20c%24)
Taking K as the constant of proportionality.
a = K b c
For b = 8 and c = 9, the value of a = 4
4 = K(8)(9)
4 = 72 K
Dividing the equation by 72, we get
![$K=\frac{1}{18}](https://tex.z-dn.net/?f=%24K%3D%5Cfrac%7B1%7D%7B18%7D)
Using the value of K in the equation:
![$a=\frac{b c}{18}](https://tex.z-dn.net/?f=%24a%3D%5Cfrac%7Bb%20c%7D%7B18%7D)
Substitute the values of b = 2 and c = 18, in the above equation
![$a=\frac{2 \times 18}{18} \\](https://tex.z-dn.net/?f=%24a%3D%5Cfrac%7B2%20%5Ctimes%2018%7D%7B18%7D%20%5C%5C)
a = 2
Therefore, the value of a exists 2.
