Answer:

257/2

Step-by-step explanation:

So in condition we need to know π=180 so when you multiply by π/180 or 180/π is one

it says we need to change from radian to degree so we need time 180/π

so it like this:

(257π)/360*(180/π)=257/2.

Twenty toothpicks, each 6 cm long, form a figure consisting of six equilateral triangles and a rectangle as shown. What is the t

Roman55 [17]

The total area of the figure is 139.20 square centimeters

Areas

The area of a shape is the amount of space it occupies

<h3>Composite figure</h3>

The figure (see attachment) is a composite figure, and the total area is the sum of the areas of each shape that makes up the complete figure

The shape has 6 equilateral triangles, each of which has an area of:

$A_1 = \sqrt{\frac{3s^2}{4}}$

Where:

$s = 6$ --- the length of each toothpick

The area of the rectangle is then represented as:

$A_2 =3s \times s$

$A_2 =3s^2$

So, the total area of the figure is:

$Total = 6A_1 + A_2$

This gives

$Total =6 \times \sqrt{\frac{3s^2}{4}} + 3s^2$

Substitute 6 for s

$Total =6 \times \sqrt{\frac{3(6)^2}{4}} + 3(6)^2$

$Total =6 \times \sqrt{27} + 108$

$Total =6 \times 5.20+ 108$

$Total =139.20$

Hence, the total area of the figure is 139.20 square centimeters

Calculate the length of the diagonal of a rectangle whose sides measure : (a) 12 meters and 48 meters (b) 11 centimetres and 60

Serggg [28]

When solving this problem, you need to imagine the diagonal line through the rectangle. This makes two triangles which you can use the pythagorean theorem for. 12 squares plus 48 squared equals 2,448. Find the square root of that at it will be your answer (I don’t have the time to figure it out). 11 squared plus 60 squared is 3,712. Square root tbd... add the label and you’re finished!

Y = x + 3<br> 4x + y = 18

Drupady [299]

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+x+3=18

(4x+x)+(3)=18(Combine Like Terms)

5x+3=18

Step 2: Subtract 3 from both sides.

5x+3−3=18−3

5x=15

Step 3: Divide both sides by 5.

5x/5 = 15/5

x=3
