Answer:
![v = 180 {cm}^{3}](https://tex.z-dn.net/?f=v%20%3D%20180%20%7Bcm%7D%5E%7B3%7D%20)
Step-by-step explanation:
V= <em>lwh</em><em> </em>or <em>l</em><em> </em><em>*</em><em>w</em><em>*</em><em>h</em>
<em>Length</em><em>:</em><em> </em><em>15</em>
<em>Width</em><em>:</em><em> </em><em>3</em>
<em>Height</em><em>:</em><em>4</em>
<em>V</em><em>=</em><em>15</em><em>*</em><em>3</em><em>*</em><em>4</em>
V=180
Answer:
The second ramp needs to have 25°.
Step-by-step explanation:
Required ramp angle for driving the car from the ground = 35°.
First ramp angle = 15°
Therefore, second ramp angle equals required ramp angle minus first ramp angle, which is = 35° - 15° = 20°
The 20° ramp angle will make the total ramp angle to be equal to 35°.
That is 15° + 20° = 35°
Answer:
D, A, I cannot read the rest of #3, C, C.
Step-by-step explanation:
Given:
A prism with right triangular base.
Base of triangle = 6 ft
Height of triangle = 8 ft
Height of prism = 7
To find:
The volume of the given prism.
Solution:
The volume of prism is:
...(i)
Where, B is the base area and h is the height of the prism.
In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:
![B=\dfrac{1}{2}\times base\times height](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20base%5Ctimes%20height)
![B=\dfrac{1}{2}\times 6\times 8](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%206%5Ctimes%208)
![B=\dfrac{48}{2}](https://tex.z-dn.net/?f=B%3D%5Cdfrac%7B48%7D%7B2%7D)
![B=24](https://tex.z-dn.net/?f=B%3D24)
Substituting
in (i), we get
![V=24\times 7](https://tex.z-dn.net/?f=V%3D24%5Ctimes%207)
![V=168](https://tex.z-dn.net/?f=V%3D168)
Therefore, the volume of the prism is 168 cubic ft.
Answer:
30
l
because it is 10 major then we remove those ten and it gives us 60 that between 2 is 30 :))
