The perimeter of a rectangular plot is 36 metres. The length is 6 metres more than the width. What is the area of the rectangular plot?​

Answers

Answer:

72 m^2

Step-by-step explanation:

Perimeter = 36

Length + width = 18

w + w + 6 = 18

2w + 6 = 18

2w = 12

w = 6

Length + 6 = 18

Length = 12

Area = 6 * 12 = 72 m^2

Answer:

200

Step-by-step explanation:

Given: they can type 120 words in 3 minutes

Find number of words they can type in 1 minute: Words typed in 1 minute = 120/3=40

Solution: Words typed in 5 minutes = 40 * 5 = 200

Answer:

200 words

Step-by-step explanation:

First we need to find the words per minuite the student can type

we can do this by taking the number of words typed in 3 mins and dividing it by 3

120/3 = 40

Now we know she types 40 words per min

multiply 40 by 5 to get the no. of words typed in 5 mins

40*5=200

f={(−2,−5),(3,−1),(1,−1)} and g={(1,1),(−1,−2),(−4,1),(−3,−1)}
Find (f+g)(1).

Answers

Answer:

[tex](f+g)(1)=0[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle f=\left\{(-2, -5), (3, -1), (1, -1)\right\}\text{ and } \\ \\ g = \left\{(1, 1), (-1, -2), (-4, 1), (-3, -1)\right\}[/tex]

And we want to find the value of (f + g)(1).

Recall that this is equivalent to:

[tex]=f(1)+g(1)[/tex]

According to the set, f(1) = -1 and g(1) = 1. Hence:

[tex]=(-1)+(1)=0[/tex]

Answers

Answer:

[tex]Area = 60x - x^2[/tex]

Step-by-step explanation:

Given

[tex]Perimeter = 120[/tex]

[tex]Side\ 1 = x[/tex]

Required

The area of the garden

First, we calculate the length of the other side using:

[tex]Perimeter = 2 *(Side\ 1 + Side\ 2)[/tex]

This gives:

[tex]120 = 2 *(x + Side\ 2)[/tex]

Divide both sides by 2

[tex]60 = x + Side\ 2[/tex]

Make Side 2 the subject

[tex]Side\ 2 = 60 - x[/tex]

So, the area of the garden is:

[tex]Area = Side\ 1 * Side\ 2[/tex]

[tex]Area = x * (60 - x)[/tex]

Expand

[tex]Area = 60x - x^2[/tex]

let y = f(x) and rearrange making x the subject

y = 2x - 10 ( add 10 to both sides )

y + 10 = 2x ( divide both sides by 2 )

[tex]\frac{y+10}{2}[/tex] = x

Find the value of x and y from the equation ​

Answers

Answer:

x = 5 and y = 3

Step-by-step explanation:

5x - 3y = 16

3x - y = 12 multiply second equation by (-3)

(-3)*(3x-y) = 12*(-3) (remember we need to multiply both sides of the equation)

-9x + 3y = -36 now subtract this from the first equation

5x - 3y -9x + 3y = 16 - 36 (-3y will eliminate +3y)

-4x = -20 and 4x = 20 divide both sides by 4

x = 5 if 3x - y = 12 then 3*5 - y = 12

15 - y = 12

-y = -3 and y = 3

If x^2 + kx + 6 = (x+n)(x + 3) for all values of x, where k and n are constants, what is the value of k?
A) 5
B) 3
C) 2
D) 1

Answers

Answer:

A) 5

Step-by-step explanation:

We are given that:

[tex]x^2+kx+6=(x+n)(x+3)[/tex]

Where k and n are constants.

And we want to find the value of k.

We can expand the right-hand side:

[tex]\displaystyle =x(x+n)+3(x+n)\\ \\ = x^2+nx+3x+3n \\ \\ = x^2 + (n+3)x+3n[/tex]

Hence:

[tex]x^2+kx+6=x^2+(n+3)x+3n[/tex]

The coefficients of each term must be equivalent. In other words:

[tex]k=n+3\text{ and } 6=3n[/tex]

Solve for n:

[tex]n=2[/tex]

Now, we can solve for k:

[tex]k=(2)+3=5[/tex]

a train leaves Westchester at 6:30. What time should it arrive at Middlewich

Answers

Answer:

a). 6:51

b). 6:30 am

c). 34 minutes

Step-by-step explanation:

a). Train leaves Westchester at 6:30.

   From the arrival - departure table in column (2),

   Arrival time of the train at middlewich = 6:51

b). Kate has to reach Southam before 9:00 am

   Therefore, time of the latest train that she can catch to get to work on time is 6:30 am

    By this train she can reach at 07:19 at Southam.

c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00

                                                                                        = 00:34

In general, a gallon of paint can cover 400 square feet. Muhanmmad needs to cover a 21 foot by 17 foot wall and a circular area with a 5 foot radius. How many gallons will he have to buy?

Answers

Answer:

1.1 gallons of paint

Step-by-step explanation:

The wall measures;

21 foot by 17 foot

Thus, area of wall = 21 × 17 = 357 ft²

Circular area has a radius of 5 ft.

Thus;

Area of circle = πr² = π × 5² = 78.54 ft²

Total area covered = 357 + 78.54 = 435.54 ft² ≈ 436 ft²

A gallon of paint can cover 400 ft²

Thus gallons Muhammad would need = 436/400 = 1.09 gallons ≈ 1.1 gallons

Glass bottles are worth 10 cents and aluminum cans are worth 5 cents. If Joe returns 12 glass bottles and 48 aluminum cans, how much money will he receive?


$1.20


$3.60


$2.40


$4.80

Answers

Answer: The answer is 3.60 dollars.

Step-by-step explanation:

1 bottle = 10 cents

12 bottles = 120 cents

100 cents = 1 dollar

1 cent = 1/100

120 = 1/100 * 120 = 1.2 dollars

now

1 aluminium can = 5 cents

48 cans = 5*48 = 240 cents

240 cents = 1/100 * 240 = 2.4 dollars

so total = (1.2+2.4) dollars

= 3.6 dollars

Answers

Answer:

it is not a deficiency, a measurement of above 60 inches is required for mon tempered glass, and given that the measurement is 63 inches, it is within the acceptable limits

Step-by-step explanation:

Tempered glass are tough glasses that are strong and do not normally break easily, tempered glass is required where the bottom edge is less than 5 feet or 60 inches above the bath the hath tub, so as to reduce the chance of the window being broken by the elbow while showering, and glasses lower than 60 inches are considered as being at risk of breaking, and should be made of tempered glass

Given that the measurement is 63 inches, the glass is not at risk and the 63 inches measurement for the given non tempered glass is not a deficiency

PLEASE PLEASE HELP ME WITH THIS QUESTION PLEASE HELP The aim of opinion writing, or persuasive writing, is to have your reader agree with your opinion/ point of view by the time they finish reading your work. This is a chance to use your persuasive skills, and your writing expertise to convince them that your stance on a particular issue or topic is the right one. This can be anything from your favourite ice cream flavour (mint chocolate chip!) to the political party you support. There are 3 main ways to frame your written arguments (or reasons) that will change your readers mind: 1. Logic: using reason or common sense is one way of helping to prove why your stance on a particular issue is the right one. For example, if I wanted to persuade you that mint chocolate chip was the best ice cream flavour (it definitely is), I might say that when you eat it, you feel refreshed, which is the exact feeling you want on a hot summer day. The logic of wanting to feel refreshed on a hot summer day is the logical argument I used to make my point. 2. Emotion: pulling at the heartstrings of your audience, or "hitting them in the feels" as the kids say, is another very effective way to persuade someone to agree with you. As an example, think of the ads that you see on TV for the SPCA, or to donate money to a cause from a developing country. Showing the sad faces of pets and children make the audience feel emotional; upset and guilty, so we pick up the phone to donate. 3. Expertise: being able to speak with authority/expertise on a specific topic, is the final way to form an argument. If you are someone who does a lot of gaming, and you are trying to tell me which video game is the best in terms of quality and overall experience, I would be inclined to believe you since you know a lot about the gaming community and would be able to give accurate information. Now that we know more about the specific ways you can argue/persuade/defend your opinion on any given topic, let's try out our new skill! Below are some questions where I will ask you to pick ONE of two things. Your task is to tell me which one is better, and WHY. For example, use persuasive writing to tell me why Coke is better than Pepsi. Once you have done this, reread your writing and tell me if your argument was one of logic, emotion, or expertise. Example: Hot OR Cold? Cold is always better than hot. In cold weather, you can bundle up in cute, cozy clothes, and snuggle with your pets to keep warm. In hot weather, I feel yucky and grumpy. Here, I used emotional arguments. *Your answers will be more detailed, but I included the above just so you have an idea of what I am asking for. *Written responses should be a paragraph EACH. 1.
