A rectangular tank measuring 12 m length, 8 m width and 6 m height is being filled with water at a rate of 550 Literminute−1 . W

marusya05 [52]

Answer:

It will take 720 minute to fill the tank

Explanation:

We have given that length of rectangular tank l = 12 m

Width w = 8 m

Rate at which water is filled in the tank = 550 l/min

And rate at which water come out from the tank = 150 l/min

So net rate of filling the tank = 550-150 = 400 l/min

Height up to which we have to fill the tank h = 3 meter

So volume of the tank $V=12\times 8\times 3=288m^3$

We know that $1m^3=1000liters$

So $288m^3=288000liters$

So required time to fill the tank $time=\frac{288000}{400}=720 minute$

It's urgent please help! find the perimeter of the triangle with vertices listed (-5,2), (3,2), (1,6)

vovangra [49]

Answer:

19.68

Explanation:

Given:

Vertices : (-5,2), (3,2), (1,6)

To get the length of each side, we need to

Length = √(x2 - x1)^2 + (y2 - y1)^2

calculate the distance between the points ;

Taking, (-5,2), (3,2)

L1 = √(3 -(-5))^2+ (2 -2)^2

L1 =√(3 + 5)^2 + 0^2

L1 = √8^2 = √64 = 8

Taking L2 ; (3,2), (1,6)

L2 = √(1 -3)^2 + (6 - 2)^2

L2 = √ (-2)^2 + 4^2

L2 = √ 4 + 16

L2 = √20 = 4.47

Taking L3 ; (-5,2), (1,6)

L3 = √(1 - (-5))^2 + (6 - 2)^2

L3 = √(1 + 5)^2 + (6 - 2)^2

L3 = √6^2 + 4^2

L3 = √36 + 16 = √52

L3 = 7.21

Therefore, perimeter = L1 + L2 + L3

8 + 4.47 + 7.21 = 19.68

Identify the sentence that depicts poor environmental quality in Sam's region.

ArbitrLikvidat [17]

Answer:

Though there is no lake or river flowing through Sam's region,

Explanation:

Environmental quality refers to the features and the properties which are ideal for a good environment. The characteristics may be either in a generalized tone or in the local aspect. These characteristics help in maintaining the life of living organisms. The quality of air, water, and sound can be stated under the features of environmental quality.

In the given passage, the quality of air in Sam's region meets good environmental quality. On the other hand, the region does not have any lake or river. Since any water body is absent, therefore, the given sentence depicts the poor environmental quality.
