Which person(s) solved each of the equation correctly?
and aren't those the names of the three main heroes of Harry Potter in the first question XD

Answer:

w = 4.

Step-by-step explanation:

-2/5 w+11 2/5=9 4/5

-2/5w + 57/5 = 49/5

Remove the fractions by multiplying thru by 5:

-2w + 57 = 49

-2w = 49 - 57

-2w = -8

w = 4.

Answer:

w=  -8/5

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

The smaller triangle seems to have dilated and formed the larger triangle. So, let's find the factor of increase.

9 / 3 = 3, so 3 is the factor of increase.

Now we need to do 4 x 3 = 12

So, ? = 12

Hope that helps!

Answer:

-5/6, -5, -√26, -31/6

Step-by-step explanation:

-5/6=-0.833

Answer:

x = 65

Step-by-step explanation:

The sum of the angles of a triangle add to 180

25+ 2x+25 = 180

Combine like terms

50+2x = 180

Subtract 50 from each side

2x = 180-50

2x =130

Divide by 2

2x/2 =130/2

x =65

Answer:

(4a - 11b)(4a + 11b)

Step-by-step explanation:

16a² - 121b² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

16a² - 121b²

= (4a)² - (11b)²

= (4a - 11b)(4a + 11b)

Answer:

Step-by-step explanation:

Rule: (a^2-b^2)=(a-b)(a+b) (‘difference of squares’)

16a^2-121b^2

(4a-11b)(4a+11b)

Answer:

i think its 25x^2

Step-by-step explanation:

5x×5x is 25x^2, because 5 × 5 = 25, and x × x = x^2

Answer:

or

Step-by-step explanation:

Area of Circle = π × radius²

Area of Circle = 12π cm

π × radius² = 12π

radius² = 12

radius = √12

radius = 3.46

Circumference = 2 × π × radius

Circumference = 2 × π × 3.46

Answer:

x = 46 degrees

Step-by-step explanation:

a triangle has a total of 180 degrees so 100 + 34 = 134 180-134 = 46

Answer:

Step-by-step explanation:

To find the value of x

x + 100 + 34 = 180. [Angle sum property of triangle]

=> x = 180 - 100 - 34

=> x = 46

Hence, required value of x is 46° (Ans)

hmmm i'm wondering if you can figure it out from here???  it's the same as the other two.. plug in that [tex]\sqrt{2}[/tex] /2  .. can you?   :)

Answer:

1

Step-by-step explanation:

every output has a different input so the answer would be one

Answer:

A function is a specific type of relation in which each input value has one and only one output value. An input is the independent value, and the output value is the dependent value, as it depends on the value of the input.

Answer:

(7B-5) +18

=2B +18

= 20 ans

Answer:

16

Step-by-step explanation:

The formula for finding the length of a side of a right triangle is:

A^2 + B^2 = C^2 (c being the hypotenuse.)

We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.

20^2 - 12^2 = 256

or in simpler terms

20^2 - 144 = 256

Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation

16^2 + 12^2 = 20^2

or in simpler terms

256 + 144 = 400

So the length of the missing leg is 16. I hope this helps :)

Answer:

C. 16

Step-by-step explanation:

In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]

We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.

To find A, put the values you already have into the formula as follows:

[tex]A^2+12^2=20^2[/tex]

Next, square each value:

[tex]A^2+144=400[/tex]

Subtract 144 from 400 to simplify the equation.

[tex]A^2=256[/tex]

And finally, find the square root of 256 to find A.

[tex]A=16[/tex]

Final answer:

C. 16

Have a nice day!

Answer:

A) x + 0

Step-by-step explanation:

In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)

In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)

Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.

Therefore, the rule for x-coordinates = x + 0

Answer: A) x + 0

Answer:

Fraction: 3/20

Decimal: 0.35

Step-by-step explanation:

a) 100% - 35% = 65

   So, 65% of the houses are NOT blue.

..............................................

Fraction: 3/20

Decimal: 0.35

Answer:

65/100 or 0.65

Step-by-step explanation:

To answer this problem all you have to do is subtract 35%.If an A+ is an 100 percent,Then subtract 100 and 35 giving you 65 percent.

But if you do not know how to turn a fraction or decimal,then i will show you.every time you have a number in the tens place,add a zero and the add the decimal and finally add 65 which making look like this:0.65.

Fraction is easy to do as long as you do a number out of 100,like this:65/100.

Answer:

That's wrong this is the answer Factor 6 out of 24 + 18 t .

the answer would be : 6 ( 4 + 3 t )

Step-by-step explanation:

Given:

Triangle QRS has coordinates Q(-2, -2), R(0, 3), and S(4, -2) and is dilated by a scale factor of 2.

To find:

The new coordinates of point S', and state whether the dilation is an enlargement or a reduction.

Solution:

If a figure is dilated by factor k with origin as center of dilation, then

[tex](x,y)\to (kx,ky)[/tex]

Where, 0<k<1 is reduction and k>1 is enlargement.

The figure is dilated by scale factor 2 which is greater than 1, so the dilation is an enlargement. The rule of dilation is:

[tex](x,y)\to (2x,2y)[/tex]

Using this rule, we get

[tex]S(4,-2)\to S'(2(4),2(-2))[/tex]

[tex]S(4,-2)\to S'(8,-4)[/tex]

Therefore, the new coordinates of point S' are (8,-4).
