$12.60 is the new price!
Step-by-step explanation:
20 x 0.7 = 14
14 x 0.9 = 12.6
Hope this helped!
5 = 15/3
3 1/3 = 10/3
15/3 - 10/3 = 5/3
so 5-3 1/3 is either 5/3 or 1 2/3.
Answer:
![\displaystyle V _{ \text{cuboid}} =280 {in}^{3}](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20V%20_%7B%20%5Ctext%7Bcuboid%7D%7D%20%3D280%20%20%7Bin%7D%5E%7B3%7D%20)
Step-by-step explanation:
we are given the base area and the height of a solid figure
since the base area is not perfect square
we assure the solid figure to be a cuboid
remember that,
![\displaystyle V _{ \text{cuboid}} = l\times w \times h](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20V%20_%7B%20%5Ctext%7Bcuboid%7D%7D%20%3D%20l%5Ctimes%20w%20%5Ctimes%20h)
we are given l×w is 40 and h is 7
so substitute
![\displaystyle V _{ \text{cuboid}} =40 \times 7](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20V%20_%7B%20%5Ctext%7Bcuboid%7D%7D%20%3D40%20%5Ctimes%207)
simplify multiplication:
![\displaystyle V _{ \text{cuboid}} =280](https://tex.z-dn.net/?f=%20%5Cdisplaystyle%20V%20_%7B%20%5Ctext%7Bcuboid%7D%7D%20%3D280)
hence,
the volume of the figure is 280 in³
