Answer: It has 4 sides
zmey [24]3 years ago

Answer:

6 sides

Step-by-step explanation:

The interior angle and exterior angle sum to 180° , then

12x + 12 + 5x + 15 = 180

17x + 27 = 180 ( subtract 27 from both sides )

17x = 153 ( divide both sides by 17 )

x = 9

Then

exterior angle = 5x + 15 = 5(9) + 15 = 45 + 15 = 60°

The sum of the exterior angles of a polygon = 360° , thus number of sides n is

n = 360° ÷ 60° = 6

Can anyone help me solve this please?
shutvik [7]

Answer:

The linear equations for the given Rectangle are

  1. y = 4x +4
  2. y = 6x - 6

Step-by-step explanation:

Given:

area given by 'y'

For figure 1,

Length  = x +1\\Breadth = 4\\\textrm{Area of Rectangle} = Length\times Breadth\\y= (x+1)\times 4\\y= 4x + 4

For figure 2,

Length  = 2x -2\\Breadth = 3\\\textrm{Area of Rectangle} = Length\times Breadth\\y= (2x-2)\times 3\\y= 6x - 6

Now we will plot the these two line on DESMOS so, we will have the intersection of these two line.

So, the intersection points are (5,24) that is x coordinate '5' and y coordinate '24'.

∴ x=5\ and\ y=24

For figure 1,

∴ Length =x+1\\=5+1\\=6\ unit\\Area=4x + 4\\=4\times5 +4\\=24\textrm{ square units}

For figure 2,

∴ Length =2x-2\\=2\times5-2\\=8\ unit\\Area=6x - 6\\=6\times5 -6\\=24\textrm{ square units}

Mary is making some shirts for her school's drama department. The fabric store has 3 1/6 yards of the fabric she wants in stock.
ddd [48]
The answer is <span>4 3/4 yards of the fabric.</span>

This can be calculated using the proportion.
If the 3 1/6 yards of the fabric is enough for <span>1 1/3 shirts, how many yards are necessary of 2 shirts:
</span>3 \frac{1}{6} yards :1 \frac{1}{3}shirts =xyards:2shirts

Let's express 3 1/6 as 19/6:
3 \frac{1}{6} =3+ \frac{1}{6} = 3* \frac{6}{6}+ \frac{1}{6} = \frac{18}{6} + \frac{1}{6} = \frac{18+1}{6} = \frac{19}{6}

Similarly, 1 1/3 = 4/3:
1 \frac{1}{3} =1+ \frac{1}{3} = 1* \frac{3}{3}+ \frac{1}{3} = \frac{3}{3} + \frac{1}{3} = \frac{3+1}{3} = \frac{4}{3}

Now, let's use this in the proportion:
<span>3 \frac{1}{6} yards :1 \frac{1}{3}shirts =xyards:2shirts
</span>\frac{19}{6} : \frac{4}{3} = x:2

Crossing the products:
x* \frac{4}{3} =2* \frac{19}{6}
⇒ x* \frac{4}{3} = \frac{19}{3}
⇒ x = \frac{19}{3} : \frac{4}{3}
x= \frac{19}{3} * \frac{3}{4}
⇒ x = \frac{19}{4} = \frac{16+3}{4} = \frac{16}{4} + \frac{3}{4} =4+ \frac{3}{4} =4 \frac{3}{4}

Therefore, Mary needs in total 4 3/4 yards of the fabric.
