In a class, 60% of the students are boys and the rest are girls. If the number of boys is 30, how many students are there? ​
irga5000 [103]

50 total students

  • 20 girls

Explanation:

total students: 100%

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

  • 60% → 30
  • 1% → 30/60
  • 1% → 0.5
  • 100% → (0.5 * 100)
  • 100% → 50

number of girls:

  • total students - number of boys
  • 50 - 30
  • 20

Solve for x and graph the solution on the number line<br> 15 &gt; 2x – 9 &gt; -23
Monica [59]

The answer is 12>x>-7

Step-by-step explanation:

it's first divided into 2 parts

1 . 15 > 2x - 9

2. 2x - 9 > -23

Then solve them individually.

let's do it,

<u>First half</u>

15 > 2x - 9

15+9 > 2x

24 > 2x

24/2 > x

12>x

<u>Second half</u>

2x-9>-23

2x>-23+9

2x>-14

x>-14/2

x>-7

<u>Joining of the two halves</u>

We have :

12>x>-7

Triangle A E C is shown. Line segment B D is drawn near point C to form triangle B D C.
AVprozaik [17]

∠BDC and ∠AED are right angles, is  a piece of additional information is appropriate to prove △ CEA ~ △ CDB

Triangle AEC is shown. Line segment B, D is drawn near point C to form triangle BDC.

<h3> What are Similar triangles?</h3>

Similar triangles, are those triangles which have similar properties,i.e. angles and proportionality of sides.

Image is attached below,
as shown in figure
∡ACE = ∡BCD ( common angle )
∡AED = ∡BDC ( since AE and BD are perpendicular to same line EC and make right angles as E and C)
∡EAC =- ∡DBC ( corresponding angles because AE and BD are parallel lines)

Thus, △CEA ~ △CDB , because of the two perpendiculars AE and BD.

PLEASE HELP ME! Images below &amp; I give Brainliest
neonofarm [45]

Answer:

Graph C with the green dots.

Step-by-step explanation:

y = 0.5x + 5 is a linear equation, so we can rule out A because it is not straight.

5 represents the y-intercept, so we rule out B because that graph doesn't intercept the y-axis at (0,5).

Graph C represents a straight line that passes through (0, 5) & has a 0.5 slope, so that is our answer.

Hope this helps. :0)
