The length of an aquarium, which has the form of a rectangular solid, is equal to 5 decimeters, and the width is 4/5 the length. when you put 40 liters of water into the aquarium, it was full to 2/3 its volume. what part of the length makes up the height of the aquarium? (1 liter is equal by volume to 1 decimeter3)

of the height makes up the height.

Step-by-step explanation:

The length of an aquarium, which has the form of a rectangular solid, is

The width is of the length, so teh width is,

Let us assume the height is 'h' dm.

So the volume will be,

As 1 liter of water occupies volume of  1 dm³, so volume of 40 liters of water will be,

This is the th of total volume.

Hence total volume will be,

Therefore,

So the part of length makes up to the height will be,

2 x t divided by n

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
