An empty rectangular tank, 40 cm long and 25 cm wide, contains 2 metal cubes of edge 10 cm. the tank is being filled with water flowing from a tap at a rate of 10 liters per minute. If it takes 3 minutes to fill up the tank, find the height of the tank.

Answers

Final answer:

The height of the tank is 0.5 cm.

Explanation:

To find the height of the tank, we can use the formula:

Volume of water = base area × height

The base area of the tank can be found by multiplying the length and width: 40 cm × 25 cm = 1000 cm².

The volume of water flowing from the tap is given as 10 liters per minute, which is equivalent to 10000 cm³ per minute or 166.667 cm³ per second. Since it takes 3 minutes to fill up the tank, the total volume of water will be 3 minutes × 166.667 cm³ per second = 500 cm³.

Now, we can plug these values into the formula to find the height:

500 cm³ = 1000 cm² × height

Dividing both sides by 1000 cm² gives:

height = 0.5 cm

Therefore, the height of the tank is 0.5 cm.

The diagonal of a square unit is x units. What is the Area of the square in terms of x

Answers

The diagonal of a square is:

d^2=s^2+s^2

d^2=2s^2  we are told that d=x  so

x^2=2s^2

Square

A square is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. All the sides of a square have the same length and each angle measure 90 degrees.

let l represent the length of the side of the square and x be the length of the diagonal. Using Pythagoras theorem:

l² + l² = x²x² = 2l²l = x√(1/2)

Area of square = l * l = x√(1/2) * x√(1/2) = x² * 1/2 = (1/2)x² unit²

A pyramid and prism have the same base area and height. The prism's base area is 8 square units and its height is 16 units. What is the volume of the pyramid? The volume of the pyramid is __________ cubic units. Enter the number that correctly fills in the blank in the previous sentence.

Answers

Prism dimensions:
8 units² (base area)
16 units (height)

Because the dimensions are the same...

Pyramid dimensions:
8 units² (base area)
16 units (height)

The volume for a pyramid = 1/3 ba * h

Substitute and solve.

   1/3 8 * 16
= 1/3 (128)
= 42.66...

Therefore the volume is approximately 42.67cm³

The volume of the pyramid with a base area of 8 square units and a height of 16 units is 42.67 cubic units.

The volume of a pyramid is calculated as one-third of the base area times the height. The base area of the given pyramid is 8 square units and the height is 16 units. Using the formula for volume V =  rac{1}{3}Ah, where A is the base area and h is the height, the volume of the pyramid can be found as follows:

V =  rac{1}{3}  imes 8  imes 16

V =  rac{1}{3}  imes 128

V = 42.67 cubic units (rounded to two decimal places).

Therefore, the volume of the pyramid is 42.67 cubic units.

a straight line is 180 degrees so we can find C by subtracting 140 from 180

180-140 = 40 degrees

all 3 inside angles need to equal 180 so now we have

180 = 40 + (2x) + (x+2)

180 =  40 +3x +2

180=42+3x

138=3x

x= 138/3 = 46


 check : 2x= 2*46 = 92

x+2 = 46+2 = 48

92 +48 +40 = 180

 so x = 46 degrees

 so angle B = 2x46 = 92 degrees

What is expansion?

Expanded form is the term used in mathematics to refer to the process of expanding a number to convey the value of every digit and place value.

In mathematics, every real-world issue may be transformed into an equation, sometimes in the form of a factor, which must then be expanded to get a solution.

If you solve a factor by opening the bracket then you will go to get on some expanded term called expansion.

Area of rectangle = length × width

Given,

Area of rectangle rug =  (3x + 9)

So,

length × width =  (3x + 9)  

length × width = 3(x + 3)

So out of 3 and (x + 3), one would be the length and one would be the width.

If the divisor is 40 what is the least three digit dividend that would give a reminder four

Answers

The "division algorithm" states that:

Dividend = Divisor × Quotient + Remainder, where R<D

for example:

115 = 7*16+3, tells us that we can fit 7 into 115 at most 16 times,


Back to our problem, the Dividend is a 3 digit number, say abc, the divisor is 40 and the remainder is 4, so we have:

Dividend = Divisor × Quotient + Remainder

abc = 40 × Quotient + 4

we can try some values for the Quotient, but it almost immediately clear that the smallest Quotient that will produce the smallest dividend is 3:

40*2+4=80+4=84 (not 3 digit)
40 * 3 + 4=120+4=124 (the smallest 3 digit dividend)

Write y less than 21

Answers

I'm assuming you want us to translate the phrase into a mathematical inequality. 

"y less than..." means the y variable is less than something. "... 12" Which is 12.

In mathematics we use the < symbol to indicate "less than"

So, y < 12 is the answer.

Answer:

21-y

Step-by-step explanation:

In mathematics the signs used for more than is + and for less than is -.

The question is asking us to write y less than 21 in mathematical statement form.

y less than 21 means 21-y,

Hence the mathematical statement for y less than 21 is 21-y.

I'm quite stuck on it. Here is the essay.Some jellyfish are smaller than a pinky finger, but some are the most toxic, like the Irukandji jellyfish. Jellyfish are some of the most dangerous creatures in the ocean, let alone the world, while some are practically harmless others, have caused multiple deaths. These jellyfish are invading the oceans that surround us, this can lead to the endangering and possibly the extinction of some creatures in the ocean. Jellyfish not only, harm people with their possibly deadly stings but many animals in the ocean are affected by the invasion and the stings of the jellyfish. Though, its hard to stop global warming and stop pollution amongst 7 billion people, there are ways to decrease the number of these jellyfish. Barriers can be created and used to somewhat stop human interaction amongst humans and jellyfish, human interaction is one thing that is causing an increase in the population of jellyfish.In the oceans, many species of dangerous jellyfish are invading. Many issues within the oceans and that are also dealt with on land are causing this to occur. Ports provide more space for jellyfish and their offspring and eggs. Pollution, global warming, and human interaction are also main factors leading to this invasion. The main issue with the jellyfish invasion is that it is putting people, sea-life, and the food chain in great danger, but another issue is that there is just way too many, in fact some jellyfish lay up to 40,000 eggs in a day, "Science data shows that over the past few years there has been an increase in swarms of jellyfish, said Steve Hay, a plankton ecologist. Even though some jellyfish are quite harmless, some are extremely dangerous and its hard to tell the difference, especially to those who dont know the difference and the different species.Many things, including the food chain are in critical danger if the jellyfish invasion isnt fixed. Some jellyfish kill sea-creatures and even people with their possibly deadly stings, and jellyfish eat preys offspring and eggs. If the invasion isnt stopped, the food chain could possibly be demolished. The demolition of the food chain, could lead to the extinction of multiple species, at the very worst it could lead to the extinctions of humans. For sea-creatures, jellyfish create a rather harsher environment for them. Also, jellyfish have clogged up power plants in multiple countries including Japan, Philippines, and Israel. This has caused power outages amongst many in those countries.There are ways to stop this invasion, but many of them are rather tough to accomplish. Stopping global warming and pollution would be very hard to accomplish amongst the more than 7 billion people in the world. But, there are some other ways that could prevent at least some of the over-growth. Decreasing the amount of ports, would decrease the amount of space where jellyfish can breed, which can lead to at-least a small decrease in jellyfish. Also, denying human interaction in some areas can decrease the jellyfish population a bit, as human interaction is a main factor in the increase of jellyfish. Also, increasing the number of Bereo jellyfish in the Black Sea can do some good for it, these jellyfish eat Mnemiopsis jellyfish, which do harm to the eco-system. But, decreasing the number of Mnemiopis is creating a more balanced system or at least in the Black Sea, We are thinking about using the Bereo in other areas, but we are concerned. There is a real fear of negative ecological consequences from introducing new species. Experts say. In Japan where their power plants are being clogged and disturbed by the increasing number of jellyfish, some high school students from Fisheries High School in Uwajima, Ehime Prefecture Japan decided to cook the jellyfish and turn them into a caramel candy hoping this can help at least a bit.
