QveST [7]

Answer: 9 L

Step-by-step explanation:

Given

The dimension of the rectangular container is $40\times 30\times 25\ cm^3$

It is filled with $\frac{3}{5}$ of the height

Water present in the container

$\Rightarrow 40\times 30\times 25\times \dfrac{3}{5}\\\\\Rightarrow 18000\ cm^3$

Also, $1\ L=1000\ cm^3$

$\therefore 18,000\ cm^3=18\ L$

Now, half of the water is poured out

So, half is left

$\Rightarrow \dfrac{18}{2}=9\ L$

Thus, 9 L of water is left in the container

Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A \sqrt4, 10,

Vika [28.1K]

Answer:

(C)

Step-by-step explanation:

In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.

A. $\sqrt{4}$ , 10 and 116

According to Pythagoras theorem,

⇒ $(116)^2=4+100$

⇒ $13456=104$

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

B. 3,6 and 8

According to Pythagoras theorem,

⇒ $(8)^{2}=(3)^2+(6)^2$

⇒ $64=9+36$

⇒ $64=45$

which does not satisfy the condition, therefore these side lengths do not form a right triangle.

C. 30, 40 and 50

According to Pythagoras theorem,

⇒ $(50)^{2}=(30)^2+(40)^2$

⇒ $2500=900+1600$

⇒ $2500=2500$

which satisfies the condition, therefore theses side lengths form right triangle.
