◆ NUMBER SYSTEMS ◆

Let 0.393939... = x
Or , x = 0.393939... ---eq.(1)

Multiplying both sides by 100

We get ,
_____ 100x = 39.393939... --- eq.(2)

Subtracting eq.(1) from eq.(2)

We get ,
100x-x = 39.393939... - 0.393939...
_____ 99x = 39

_____x = \frac{39}{99} \\ \\ x = \frac{13}{33} \: \: \: \: \: \: \: \: \: \: \: Ans.

State if each triangle is acute, obtuse,or right using Pythagorean theorem converse.
shtirl [24]

Answer:

Right triangle

Step-by-step explanation:

Properties for acute, obtuse or right triangle,

1). Given triangle will be a right triangle if,

   Hypotenuse² = (Leg 1)² + (Leg 2)²

2). Triangle will be an acute triangle if,

   (Largest side)² < (leg 1)² + (leg 2)²

3). Triangle will be an obtuse triangle if,

   (Largest side)² > (leg 1)² + (leg 2)²

Now we apply these properties in the given triangle,

(Largest side)² = (√11105)²

                        = 11105

(leg 1)² = (76)²

           = 5776

(leg 2)² = (73)²        

            = 5329

Since 11105 = 5776 + 5329 (First Property)  

11105 = 11105

Therefore, given triangle is a right triangle.

There are 52 weeks in a year. Ben has lived in london for two fifths of year. How many weeks has ben lived in london?
masha68 [24]

Answer:

\frac{104}{5} weeks or 20\frac{4}{5} weeks

Step-by-step explanation:

To do this we can set up a proportion

\frac{52}{1} *\frac{2}{5}

This will tell us how many weeks are in 2/5 of a year

Let's evaluate this

\frac{104}{5}

We cannot simplifiy this anymore, so we will leave it as an improper fraction, or a mixed number as shown below

20\frac{4}{5} weeks

The figure shows the construction steps to bisect an angle. The steps are in an incorrect order. What is the correct order of th
klemol [59]

Answer:

The correct order of the steps is CEABD ⇒ B

Step-by-step explanation:

Let us arrange the figures

To construct a bisector of an angle

First: Draw angle AOB

First step is figure C

Second: Place the pin of the compass on point O and draw an arc intersects the two sides of the angle OA and OB at points D and E

Second step is figure E

Third: Place the compass on point D and draw an arc in the interior of the angle

Third step is figure A

Fourth: without change the open of the compass place its pin on point E and draw an arc which intersects the arc drawn from point D at point C

Fourth step is figure B

Fifth: Draw a line from point A to point C, this line AC is the bisector of angle AOB

Fifth step is figure D

The correct order of the steps is CEABD
