The area of a circle is 3.14 square meters, What is the circle's diameter?

Answer:

[tex]\huge\boxed{\sf (10x+9)^2}[/tex]

Step-by-step explanation:

[tex]\sf 100x^2 + 180x+81\\\\= (10x)^2 + 2(10x)(9)+ (9)^2\\\\Using \ Formula \ a^2 +2ab+b^2 = (a+b)^2\\\\= (10x+9)^2\\\\\rule[225]{225}{2}[/tex]

Hope this helped!

Answer:

[tex](10x + 9 {)}^{2} [/tex]

Step-by-step explanation:

1) Rewrite it in the form a² + 2ab + b², where a = 10x and b = 9.

[tex](10x) ^{2} + 2(10x)(9) + {9}^{2} [/tex]

2) Use square sum: ( a + b )² = a² + 2ab + b².

[tex](10x + 9 {)}^{2} [/tex]

Hence, the answer is (10x + 9)².

Answer:

3

Step-by-step explanation:

Evaluate F(x) = –x^2 – 4x by substituting -1 for x:

              F(-1) = –(-1)^2 – 4(-1)

This becomes:

               F(x) = –1 + 4  =  3

Answer:

a = 4

Step-by-step explanation:

a² = 5² - 3²

a² = 25 - 9 = 16

√16 = 4

a = 4

Answer:

a = 4

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 3² = 5²

a² + 9 = 25 ( subtract 9 from both sides )

a² = 16 ( take the square root of both sides )

a = [tex]\sqrt{16}[/tex] = 4

Answer:

1.) 138

2.) 55

Step-by-step explanation:

1.) 8 x 6 = 48 x 2 = 96

   (middle) 8 x 3 = 24

   (triangles) 6 x 3 = 18 divided by 2 = 9 x 2 = 18

96 + 24 + 18 = 138

2.) (middle) 5 x 5 = 25

    (triangles) 5 x 3 = 15 divided by 2 = 7.5 x 4 = 30

     30 + 25 = 55

Hey mate.....

Step-by-step explanation:

This is ur answer.....

M.A 1 = 180 - 125 ( Supplementary angle)

M.A 1 = 55

M.A 3 = 125 (Vertically Opposite Angles)

M.A 4 = 55 (Vertically Opposite Angles)

M.A 5 = 55 ( Corresponding Angle)

M.A 6 = 125 ( Corresponding Angle)

M.A 7 = 125 ( Vertically Opposite Angle)

M.A 8 = 55 ( Vertically Opposite Angle)

Answer:

∠1 = 55°

∠3 = 125°

∠4 = 55°

∠5 = 55°

∠6 = 125°

∠7 = 125°

∠8 = 55°

Step-by-step explanation:

This is the detective case for vertical angles!!(dun-dun-dun!!!!)

Ok the info we have is that Angle 2 is 125°

Ok, quick,  take ten seconds, the other group might take the victory coin. What is the vertical angle for angle 2?

-----

3! Correct

3 is the vertical angle because it is one part of the pair of opposite angles made by two intersecting lines.

3 is now 125°

The sum of all angles 1,2,3,4 is 360°

360° - 125° - 125° = 110°

110° / 2 (because 1 and 4 are vertical, they are equal) = 55°

1 = 55° and 4 = 55°

Lets do this for 5,6,7, and 8

Angle 1 = angle 5 because it is the law of same side interior(corresponding) angles, or they are the same because the lines are parallel to each other.

So angle 5= 55°

then angle 8 = 55°

6 = 125° and 7 = 125°

Yay you beat the other team. Great job you win a victory coin(which basically is something that is absolutely nothing)

Answer:

6.45 cm by 1.8 cm

Step-by-step explanation:

Ratio of label to actual measurement ; 2 : 3

For a flyer label size of 4.3

Actual label size equals :

(Flyer ratio / total ratio) * total size = flyer size

2/5 * x = 4.3

2x / 5 = 4.3

2x = 21.5

x = 21.5 / 2

x = 10.75

Actual size =. 10.75 - 4.3 = 6.45 cm

2/5 * x = 1.2

2x / 5 = 1.2

2x = 6

x = 6 / 2

x = 3

Actual size = 3 - 1.2 = 1.8 cm

6.45 cm by 1.8 cm

The other triangle has 2 dashes for the side. THe other two have the same markings.

19.87 = 100%

If you divide both sides by ten, you would get what ten percent is.

1.987 = 10%

Multiply this by two to get 20%.

3.974 = 20%

Minus twenty percent from the original amount.

18.87 minus 3.974 = 15.886 after the discount.

Answer:

Ava's altitude is 3 meters.

Step-by-step explanation:

The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.

So that applying the Pythagoras theorem, we have;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]

25 = 16 + [tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 25 - 16

   = 9

x = [tex]\sqrt{9}[/tex]

   = 3

x = 3 meters

Thus, Ava's altitude is 3 meters.

Answer:Matti has 3pencils

Step-by-step explanation:

Given that Jorge has 5pencils

Renaldo has 1more than Jorge that means ,he has 5 +1=6pencils

But also

Renaldo =3Chang-Lin

6==3Chang-Lin

Chang-Lin = 6/3 =2

Since Chang-Lin has 2, Matti having 1more I than Chang-Lin will have 2+1=3pemcils

Step-by-step explanation:

Use the cone area theorem

Answer: The answer would be B

Write out the equation in slope-intercept form:

y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)

Subtract -5/3 from both sides of the equation:

y+5/3x=6

Subtract 6 from both sides:

y+5/3x-6=0

Multiply both sides by 3 to get rid of the fraction:

3y+5x-18=0

Then arrange the numbers to x and y are on one side by itself:

3y+5x=18

And that's your answer!

Hope this helped you!
