We have  \(AB=AM+BM=10+6=16;BC=BN+CN=6+x;CA=CP+AP=x+10\).

The triangle ABC has his edges   \(a=10+6=16;b=6+x;c=x+10\) . Call  \(p\)  is the halp perimeter of \(ABC\) then  \(p-a=10,p-b=6,p-c=x\) and the area of ABC is

                                      \(\sqrt{p\left(p-a\right)\left(p-b\right)\left(p-c\right)}=\sqrt{60x\left(16+x\right)}\) .

By the assumptions we have    \(60x\left(x+16\right)=\left(120\sqrt{3}\right)^2\Leftrightarrow x^2+16x-720=0\Leftrightarrow x\in\left\{20;-36\right\}\).

So, \(x=20;p=36\), the perimeter of  ABC is  72.

Suppose CH is the height of CAB, then \(CH=\dfrac{2.120\sqrt{3}}{16}=15.\)  The triangle CHA has

                                  \(CHA=90^0;CH=15;CA=30\Rightarrow A=60^0\). 

The measure of angle A is    \(60^0\) .

We have  AB=AM+BM=10+6=16;BC=BN+CN=6+x;CA=CP+AP=x+10

.

The triangle ABC has his edges   a=10+6=16;b=6+x;c=x+10

 . Call  p  is the halp perimeter of ABC then  p−a=10,p−b=6,p−c=x

 and the area of ABC is

                                      √p(p−a)(p−b)(p−c)=√60x(16+x)

 .

By the assumptions we have    60x(x+16)=(120√3)2⇔x2+16x−720=0⇔x∈{20;−36}

.

So, x=20;p=36

, the perimeter of  ABC is  72.

Suppose CH is the height of CAB, then CH=2.120√316=15.

  The triangle CHA has

                                  CHA=900;CH=15;CA=30⇒A=600

. 

The measure of angle A is    600

 .

We have :

\(=\dfrac{x+2}{89}+1+\dfrac{x+5}{86}+1>\dfrac{x+8}{83}+1+\dfrac{x+11}{80}+1\)

\(=\dfrac{x+91}{89}+\dfrac{x+91}{86}>\dfrac{x+91}{83}+\dfrac{x+91}{80}\)

\(=\dfrac{x+91}{89}+\dfrac{x+91}{86}-\dfrac{x+91}{83}-\dfrac{x+91}{80}>0\)

\(=\left(x+91\right)\left(\dfrac{1}{89}+\dfrac{1}{86}-\dfrac{1}{83}-\dfrac{1}{80}\right)>0\)

To \(\dfrac{1}{89}+\dfrac{1}{86}-\dfrac{1}{83}-\dfrac{1}{80}\) different 0

\(=x+91>0\)

\(=x< -91\)

e have :

=x+289+1+x+586+1>x+883+1+x+1180+1

=x+9189+x+9186>x+9183+x+9180

=x+9189+x+9186−x+9183−x+9180>0

=(x+91)(189+186−183−180)>0

To 189+186−183−180

different 0

=x+91>0

=x<−91

The amount of money she spends in all is:

18.03 + 19.94 = 37.97 (dollars)

The amount of money she spends in all is:

18.03 + 19.94 = 37.97 (dollars)

She spent in all : 18,03 + 19,94 = 37.97 ( dollars )

The messenger reaches the second army after : 10/(9 +1) = 1 hour.

At the time of the messenger leaving the second army, the distance between him and the first army is:  10 - 2.1 = 8 miles.

The messenger meets the first army after 8/(9 + 1) = 0.8 hours more.

When the messenger gets back to the first army, two armies take 1 + 0.8 = 1.8 hours.

And the distance between two armies is : 10 - (1 + 1) 1.8 = 6.4 miles.

\(x\div3\div2=9\)

\(\Rightarrow x=9.3.2\)

\(\Rightarrow x=54\)

Vậy \(x=54\) thì thỏa mãn

x:3:2=9

\(\Leftrightarrow x=9.2.3\)

\(\Leftrightarrow x=54\)

So the answer is 54

X : 3 : 2 = 9

X : 3 = 9 x 2

X : 3 = 18

X = 18 x 3

X = 54

Number of prize winners: 2562 - 1602 = 960 (you)
Call a number of Gold Medal students
Because: The number of Silver medal students is twice the number of Gold medal students, the number of Bronze medal students twice the number of Silver medal students, Won the bronze medal. Inference: The number of Gold Medal students is:
A + 2a + 4a + 8a = 960
15a = 960
A = 960: 15
A = 64
Because: There are 12.5% of the students winning the gold medal has an absolute score of 300 points. Find out: The number of Gold medalists scoring an absolute 300 points is: 64 x 12.5: 100 = 8 (you)
