Step-by-step explanation:

Given:

Height of solid box (h) = 20 cm

Width (w) = 80 cm

Length (l) = 10 cm

Cost of paint = £0.04 per cm²

Required:

Cost of painting the box

Solution:

✔️First, find the surface area of the box

Surface area = 2(l*w + l*h + w*h)

S.A = 2(10*80 + 10*20 + 80*20)

S.A = 2(800 + 200 + 1,600)

S.A = 2(2,600)

S.A = 5,200 cm²

✔️Find the cost of painting 5,200 cm² surface area of the box.

Cost of pianting 1 cm² = £0.04

Cost of painting 5,200 cm² = 5,200 × 0.04

Cost of painting the box = £208

Answer: The length of the fence will be 150 feet

Step-by-step explanation:

The question is asking you to find the hypotenuse of a rectangle with a length of 120 feet and a width of 90 feet. To find the hypotenuse we will need to use the formula   a^2 + b^2 = c^2

120 feet will be a

90 feet will be for b  

this is because a and b are the two legs of the rectangle.

120^2 + 90^2 = c^2

14400 + 8100 = c^2

22500 = c^2

   c =√22500

 c= 150

I think its 15^-7

Step-by-step explanation:

you can forget about the one and just look at the 15 and 7 which you get 15^-7

The fraction (1/15)⁷ can be written as 15⁻⁷ after using the properties of the integer exponent.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

Answer:

There is not an actual question here, so i will answer this in a general way.

The initial height of the tree is 4 ft.

We know that every 5 weeks, the tree grows 2 ft

Then the rate at which the tree grows can be calculated as:

R = (how much it grows)/(in how much time)

Then:

R = (2 ft)/(5 weeks) = 0.4 ft/week

This means that the tree grows 0.4 feet per week.

Then we can write the equation:

H(w) = 4ft + (0.4ft/week)*w

Where w is the number of weeks since John planted the tree.

So if we want to know the height of the tree in a particular week, like week 3, we just need to replace w by 3 weeks in the above equation:

H(3 weeks) = 4ft + (0.4 ft/week)*(3 weeks)

                   = 4ft + 1.2 ft = 5.2 ft

All positive real numbers

Step-by-step explanation:

Given

The model can be represented as:

[tex]y = f(x)[/tex]

[tex]y = distance[/tex]

[tex]x = time[/tex]

Required

Determine the domain

This means that we list out possible values of x.

If x represents time, then it is impossible for x to be negative.

This implies that x can take any value as long as it is greater than or equal to 0.

Hence, the domain is all positive real numbers

Question 20: Cumulus

Step-by-step explanation:

The force applied moves the object in the direction of the force. Suppose if the force is applied to the moving object in that case object moves in the direction of the stronger force. Thus, according to the given question the applied force moves the object in its direction

Work is when there is energy that is exerted throughout an object using force and action. Which displaces the measure of the force and the application of that specific action.

Given:  

Force applied F = 50 N  

Distance s = 15 m  

Find:  

Work done W  

Computation:  

Work done W = Force x distance  

Work done W = 50 x 15  

Work done W = 750 J

A Pair of tweezers is an example of a Third Class lever. The force is applied in the middle of the tweezers which causes a force at the tips of the tweezers. The fulcrum is where the two halves of the tweezers are joined together.   Whereas a pair of scissors and a pair of pliers is an example of a first class lever.

Power is the rate of using energy or the rate of doing work. Basically, any units of energy (or work) and time can be used to generate a unit of power and can be computed as Work/time. Watt is the standard metric unit of power.

We can use a case scenario to illustrate what Power is. If you take a book and lift it a meter high, you will end up doing the same amount of work regardless of whether you lift the book slowly or quickly. However, you can increase your power which is the rate of doing work when you lift the book quickly.

Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 - 1819)

energy which a body possesses by virtue of being in motion is kinetic

Kinetic energy is when an object has the power to move, Potential energy would be when its resting on the shelf.

Earth is surrounded by invisible gases that form a thin protective blanket that we call the atmosphere. It contains the oxygen that we breath as well as other important gases such as nitrogen, carbon dioxide, water vapor, and ozone.

The permanent gases whose percentages do not change from day to day are nitrogen, oxygen and argon. Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.

Problem 3

-----------------------------

Explanation:

It doesn't matter what shape the base is, so the fact it's a hexagon isn't useful info here. What is useful is that the area of the base is 25 square inches.

We multiply this base area by the height, and then divide by 3 to get the volume of the pyramid.

V = (BaseArea*height)/3

V = (25*9)/3

V = 75 cubic inches

==========================================================

Problem 4

The approximate volume is found by using pi = 3.14

-----------------------------

Explanation:

We apply this formula to find the volume of a cone

V = (1/3)*pi*r^2*h

In this case, r = 12 is the radius (half the diameter) and h = 30 is the height.

So,

V = (1/3)*pi*12^2*30

V = (1/3)*pi*4320

V = (1/3)*4320*pi

V = 1440pi ...................... exact volume in terms of pi

V = 1440*3.14

V = 4521.6 ....................... approximate volume if you use pi = 3.14

==========================================================

Problem 5

-----------------------------

Explanation:

Mary's cube has side lengths of 5 inches, so the volume of this cube is 5*5*5 = 5^3 = 125 cubic inches.

James then wants to triple the side lengths of her cube to have a new larger cube that has side lengths of 3*5 = 15 inches. The volume of this new larger cube is going to be 15*15*15 = 15^3 = 3375

To compare the two volumes, we'll divide the larger over the smaller

(larger volume)/(smaller volume) = (3375)/(125) = 27

This number 27 is due to cubing the value 3, ie 3^3 = 3*3*3 = 27

So the larger cube is 27 times larger compared to the smaller cube.

As another example, let's say he wanted to only double the side lengths. This would mean the larger volume is 8 times larger, since 2^3 = 2*2*2 = 8. Whatever the linear scale factor is, cube it and you'll get the volume scale factor.

Answer :

[tex]\boxed{\textsf{ The final answer is \textbf{n}$^{\textbf{3}}$ .}}[/tex]

Step-by-step explanation:

Its given that n is the middle out of the three consecutive integers . So ,

The last integer will be :-

[tex]\sf\implies Last \ Integer \ = \ n - 1 [/tex]

The next Integer will be :-

[tex]\sf\implies Next \ Integer \ = \ n + 1 [/tex]

Now the Question says that the three integers are multipled to give a product . So that would be.

[tex]\sf\implies Product_{(three\ consecutive\ integers)}= (n-1)n(n+1) = (n^2-1)(n) = \pink{n^3-n}[/tex]

Now thirdly it's given that n is added to the given integer . That would be ,

[tex]\sf\implies Adding\ n = \ n^3 - n + n = \pink{n^3} [/tex]

Here - n and +n gets cancelled. So we are ultimately left out with n³.

Hence the final number is a cube of some number.

The result is n³.

Numbers that appear in a particular order are known as consecutive numbers. Every pair of numbers has a difference of one. The mean and median of consecutive numbers are equal. In the event that n is a number, n, n+1, and n+2 would be consecutive numbers.

Given three consecutive positive integers,

and middle integer is n

the integer before n is (n - 1)

the integer after n is (n + 1)

product of three integer is

(n - 1) × n × (n + 1)

(n² - 1) × n

n³ - n

now add n in product

n³ - n + n

n³

Therefore, the result is n³.
