Answer: -13/3

Step-by-step explanation: -1  5/8  -> -13/8        2  2/3->  8/3

-13/8 x 8/3 = -104/24

                  = -13/3  OR  -4   1/3      

-2/9 n= - 8

2n = 72

N=36

Answer:

[tex]n = \frac{1}{36} [/tex]

Step-by-step explanation:

[tex] \frac{ - 2}{9n} + 14 = 6[/tex]

[tex] - \frac{ 2}{9n} + 14 = 6[/tex]

[tex] - \frac{2}{9n} = 6 - 14[/tex]

[tex] - \frac{2}{9n} = - 8[/tex]

[tex]2 = 72n[/tex]

[tex]n = \frac{1}{36} [/tex]

Answer:

0

Step-by-step explanation:

To find the slope, we can use the slope formula

m = (y2-y1)/(x2-x1)

    = (0-0)/(4- -10)

    = (0-0)/(4+10)

    = 0/14

   =0

Answer:

x = 10

Step-by-step explanation:

By the Vertical Angles Theorem that states the vertical angles are congruent.

4x+8 = 2x + 28

    -8           -8

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

4x = 2x + 20

-2x    -2x

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

2x = 20

/2      /2

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

x = 10

Answer:

[tex](4x + 8) = (2x + 28) \\ \\ 4x + 8 = 2x + 28 \\ \\ 4x - 2x = 28 - 8 \\ \\ 2x = 20 \\ \\ x = \frac{20}{2} \\ \\ x = 10[/tex]

Answer:

62,144

Step-by-step explanation:

60,000 x (1 + 2%)^2 : growth in 2 years

+ 750: in migrants

- 410: out migrants

- 620: died

Answer:

62,144

Step-by-step explanation:

[tex]60,000 \times (1 + 2\%)^{2} [/tex]

➡️ [tex] = 62,424[/tex]

In-migrants:

➡️ [tex]750 - 410 = 340[/tex]

now:

[tex]62,424 + 340 - 620[/tex]

➡️ [tex] = 62,144[/tex]

So, the present of the municipality is 62,144

Answer:

Step-by-step explanation:

diagonal  = 32 cm

Area of square = [tex]\dfrac{d^{2}}{2}[/tex]

                        [tex]=\dfrac{32*32}{2}\\\\=512 \ cm^{2}[/tex]

Diagonal separate the square into two equal triangles.

Area of upper triangle that is shaded black = area of lower triangle = 512/2

= 256 cm²

Isosceles triangle:

a = 6 cm  ; b = 6 cm c = 8cm

[tex]s = \dfrac{a+b+c}{2}\\\\=\dfrac{6+6+8}{2}\\\\=\dfrac{20}{2}\\\\=10\\\\s-a = 10 - 6 = 4 \ cm\\\\s-b = 10-6 = 4 \ cm\\\\c - c = 10 - 8 = 2 \ cm\\\\Area = \sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{10*4*4*2}\\\\=\sqrt{2 * 2 * 4 * 4 * 5}\\\\=4*2\sqrt{5}\\\\=8\sqrt{5}\\\\=8*2.24\\\\=17.92 \ cm^{2}[/tex]

Area of black shade paper = 256 + 17.92 =  273.92 cm²

Area of white shade paper = 256 cm²

Area of the isosceles triangle = s(s-a)(s-b)(s-c)

Answer:

a=5 and b=9

Step-by-step explanation:

(x, y) = (s, t) => x=s and y=t

Hence, a+3=b-1 and b-2=2a-3, solving we get a=5 and b=9

Hey there! I'm happy to help!

A translation is just when they are staying the same. You just move the figure along but it doesn't switch the way it is facing.

A reflection is when it is like going over a mirror. It's kind of like it rolls over. So if you are facing left on the ground and you roll over then you are facing the right. That's basically what a reflection is.

A rotation is pretty self explanatory, it's when you twist it sideways, upside down, etc. A rotation can also end up in the same position as a reflection. For example if you diagonally reflect something it is the same as a 180 degree rotation, and that might be what is stressing you out.

With your answers, I'm assuming each number has all three possible answers, so if one seems to have both, just see which answer you haven't used yet.

1) Rotation, Translation Reflection

2) Rotation, Reflection, Translation

3) Translation, Rotation, Reflection

4) Rotation, Reflection, Translation

5) Reflection, Rotation, Translation

6) Reflection, Rotation, Translation

Answer:

honestly, the graph look totally fine...

If one ere pressed to find something to complain about it, one could suggest that  you do not know if this was the starting price of the stock or the ending price of the stock each day?... One could also argue that to be a bit more meaningful you might want to know the range of prices during each day...

look up what is called a candle stick graph.. each day looks like a candlestick... the top is the highest value each the bottom the lowest, and there is a line in the candle that  shows the closing price

Answer:

17

Step-by-step explanation:

Evaluate the 2 expressions by substituting x = 2 , y = 3 into them

3x² - 2y

= 3(2)² - 2(3)

= 3(4) - 6

= 12 - 6

= 6

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

3y² - 2x

= 3(3)² - 2(2)

= 3(9) - 4

= 27 - 4

= 23

Then 23 - 6 = 17

Answer:

160 cm²

Step-by-step explanation:

If the two rectangles are similar, that means they have equal scale factors.  The smaller rectangle has length of 8 cm and area of 40 cm, which means the width is 5 cm.  

The width of the larger rectangle is 10 cm, which is double the width of the smaller, similar rectangle.  So, to find the length of the larger rectangle, multiply 8 x 2, which gives you 16 cm for the length, since the scale factor is 2.

Now, just find the area of the larger rectangle by doing length x width.  16cm x 10 cm = 160 cm²

Answer:

160 cm^2

Step-by-step explanation:

Our strategy is to find the length of the larger rectangle so we can find the area. To find the length, we will rely on the fact the two rectangles are "similar": their sides are in equal proportions, or have the same "ratio."

We know that the smaller rectangle has a width of 5 cm because, when we substitute area and length into

A = lw

we get

40 = 8w

w = 5

when we divide both sides by 8.

Because of equal proportions:

Width : length of the smaller rectangle = Width : length of the larger rectangle

We can write an equation

5 / 8 = 10 / x

Cross multiply

5x = 80

x = 16

So the larger rectangle has a length of 16 cm and a width of 10 cm (given)

meaning the area is

16 * 10 = 160 cm^2

Answer:

Below

Step-by-step explanation:

You can use this formula to find the sum of an arithmetic series

     Sn = n / 2 (a1 + an)

You need to find the number of terms in each series before using the formula

     Tn = a + (n - 1) d

a) 53 = 5 + (n - 1) 3

      n = 17

Sn = 17 / 2 (5 + 53)

    = 493

b) 98 = 7 + (n - 1) 7

      n = 14

Sn = 14 / 2 (7 + 98)

   = 735

c) -102 = 8 + (n - 1) -5

        n = 23

Sn = 23 / 2 (8 + (-102))

   = - 1081

d) 41/3 = 2/3 + (n - 1) 1

        n = 14

Sn = 14 / 2 (2/3 + 41/3)

    = 301 / 3 or 100 1/3  

Hope this helped! Best of luck <3

Answer:

2x

Step-by-step explanation:

I'm going to guess that the diagram means that you have 4*(+x) and you subtract 2(x) leaving you with 2x

The ones are a bit harder
