xxTIMURxx [149]

Answer:

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

Step-by-step explanation:

Given:

Consider a rectangle ABCD as shown in the figure below where,

Area (ABCD) = 635 × 7 = 4445

Therefore length and width of a rectangle will be

LENGTH =635 = AB

WIDTH  = 7 = AD

To Find:

AE =?

EF = ?

FB = ?

Ar(EFGH)=?

Ar(ABCD) =?

Solution:

We know that area of the rectangle is given by

\textrm{Area of rectangle}= LENGTH\times WIDTH

\textrm{Area of rectangle ABCD}= 635\times 7=4445\ unit^{2}

Substituting the values we get

\textrm{Area of rectangle AEHD}= AE\times 7\\\\4200=AE\times 7\\\therefore AE=\dfrac{4200}{7}=600

Similarly for area rectangle FBCG,

\textrm{Area of rectangle FBCG}= FB\times 7\\\\35=FB\times 7\\\therefore FB=\dfrac{35}{7}=5

Now we have

AB = 635,

AE + EF + FB = 635\\\\600+EF+5=635\\\\EF=635 -605=30\\\therefore EF = 30

Similarly for area rectangle EFGH,

\textrm{Area of rectangle EFGH}= EF\times 7\\\\=30\times 7=210\ isunit^{2}

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

Four big water bottles can hold 8 gallons of water. How much water can ten big water bottles hold.
g100num [7]

Step-by-step explanation:

<u>Part 1</u>

To find out the amount of water ten big water bottles can hold, we have to find out how much water is in each water bottle. To do this, we divide the amount we are looking for by the number of items.

8 ÷ 4 = 2

Part 1 answer: Each water bottle can hold <u>2 gallons</u> of water.

<u>Part 2</u>

Now that we know the amount of water in each water bottle, we can find out how much water 10 water bottles can hold. To do so, we multiply our previous answer, 2, by the number of items (10).

2 • 10 = 20

Part 2 answer: 10 water bottles can hold <u>20 gallons</u> of water.

Our final answer: 20 gallons

I hope this helps you!

The sum of three consecutive natural numbers is 450 find the numbers. The three numbers in increasing order are?
pantera1 [17]

Answer: 149,150,151

Step-by-step explanation:

1.st solution

Let the smallest number is x.

So next consecutive number is x+1

So the third consecutive number is x+2

So the sum of these three numbers is:

x+x+1+x+2=450

3x+3=450

3x=447

x=149  - first number

Second number is 149+1=150

Third number is 150+1=151

2-nd solution

The sum of 3 numbers in row is 450. It means that average  number is 450:3=150 - is the number which is in the middle

So the first one number is 150-1=149 and the third number is 150+1=151

Solve the equation for x 25=1/x​
Mkey [24]

Answer:

x = 1/25

Step-by-step explanation:

Solve for x:

25 = 1/x

25 = 1/x is equivalent to 1/x = 25:

1/x = 25

Take the reciprocal of both sides:

Answer:  x = 1/25

Atraeus is solving the quadratic equation by completing the square. 7x2 – 14x + 6 = 0 7x2 – 14x = –6 A(x2 – 2x) = –6 What is the
Vedmedyk [2.9K]
So we first minus 6 both sides
7x^2-14x=-6
then we have
A(x^2-2x)=-6
what is A?

hmm (this should be painfully obvous, but if not, here are steps)

7x^2-14x=-6
A(x^2-2x)=-6

7x^2-14x=-6=A(x^2-2x)
7x^2-14x=A(x^2-2x)
undistribute 7
7(x^2-2x)=A(x^2-2x)
divide both sides by (x^2-2x)
7=A

A=7
