Answer:

  x = (10√3)/3 ≈ 5.7735 m

Step-by-step explanation:

The 30°-60°-90° right triangle is one of the "special" right triangles, so you know its side ratios are ...

  BC : AB : AC = 1 : √3 : 2

Then ...

  x = BC = AB/√3 = (10 m)/√3 = (10√3)/3 m ≈ 5.7735 m

Find the solution to the system of equations!
Crazy boy [7]
The answer to the system of equations is x = 3, y = -2 and z = 5. 

In order to find this you can use elimination to create two equations with only x and y. First we will add equation one with equation 2 multiplied by 2. 

-x + 2y + 2z = 3
6x + 2y - 2z = 4
---------------------
5x + 4y = 7

Then  we can add equation 2 with equation 3. 

3x + y - z = 2
2x + y + z = 9
------------------
5x + 2y = 11

Now we can use these two equations together to solve for y. It will be easiest if we multiply the second one by -1. 

5x + 4y = 7
-5x - 2y = -11
------------------
2y = -4

And then we can solve for y. 

2y = -4
y = -2

With that answer we can go back to any equation with just y and x and solve for x. 

5x + 4y = 7
5x + 4(-2) = 7
5x - 8 = 7
5x = 15
x = 3

Now we can use x and y in any equation to find z. 

2x + y + z = 9
2(3) + (-2) + z = 9
6 - 2 + z = 9
4 + z = 9
z = 5

five silver coins weigh 125gm and are worth $6. Ten bronze coins weigh 500gm and are worth 80 cents. A number of silver and bron
Kisachek [45]

Answer:

100 silver coins and 175 bronze


Step-by-step explanation:

let x be the number of silver coins and y the number of bronze coins.  

Worth of these coins together = 6x/(5)+0.08/(10)y

=1.2x+0.008y

Weight of one silver coin = 125/5 = 25 gm

and one bronze coin = 500/10 = 50 gms.

Weight of these coins together = 25x + 50y

Equate these two items i.e. value and weight to actuals given.

i.e. 1.2x+0.08y = 134 and    ... i

25x+50y = 11 kg 250 gm = 11250 gms. ... ii

Divide the second equation by 25

x+2y = 450   ...  iii

Multiply I equation by 25

30x+2y =3350   ... iv

iii-iv gives -29x = -2900 or

x =100

Substitute in x+2y = 450

2y = 350 or y =175
