A large storage tank holds 2900 m3 of a liquid mixture that has 112% of the density of water. The tank is in an empty warehouse

frez [133]

Answer:

Part a) The height that the liquid forms equals 2.56 feet.

Part b) The number of trucks required are 361.

Step-by-step explanation:

When all the liquid mixture is spilled from the storage tank it will accumulate over the floor space.

Thus we infer

$V_{spilled}=V_{accumulated}$

where

$V_{spilled}$ is spilled volume of mixture = $2900m^{3}$

$V_{accumulated}$ is accumulated volume over the floor

Since the floor is smooth thus we conclude that the accumulated volume will form a prism of liquid with height 'h'

Thus

$V_{accumulated}=Area\times h=40000\times h$

Equating both the volumes we get

$40000\times h=2900m^{3}\times \frac{35.314ft^{3}}{m^{3}}=102412.533ft^{3}\\\\\therefore h=\frac{102412.533}{40000}=2.56 feet$

Thus the height formed by the liquid equals 2.56 feet.

Part b)

We know that the basic relation between density, mass and volume is

$Mass=density\times volume$

Since it is given that the density of the liquid is 112% the density of water thus we have

$density_{liquid}=1.12\times density_{water}\\\\density_{liquid}=1.12\times 1000=1120kg/m^3$

Thus the weight of the volume of liquid is

$mass=2900\times 1120=3248000kg$

Now since it is given that 1 truck can carry 9000 kg of liquid thus by proportion the number of trucks need to carry 3248000 kilograms of liquid equals

$n=\frac{3248000}{9000}=360.88\approx 361$

Are the triangles congruent? Why or why not?

Annette [7]

It would be C.

In the second triangle if you add the angles 58+33 to angle C 88, you get 179, not 180. So the triangle dont share the same angles meaning they arent congruent.
