Answer:

6/12 = 0.5

Solution:

<u>Note that:</u>

Probability that the tile will be green: Green tiles/Total tiles

  • Green tiles/Total tiles
  • => 6/6 + 3 + 3
  • => 6/12 = 1/2 = 50/100 = 0.5

The probability (In decimal) of obtaining a green tile is 0.5.

The sides of a triangle are x,x+1,2x-1 and its area is x root 10. Find the value of x
Marianna [84]
<span>You can use Heron's formula to solve this problem.

</span>A= \sqrt{s(s-a)(s-b)(s-c)} , where A is the area; a,b,с are the sides;  s<span> is the </span>semiperimeter<span> of the triangle
</span>s= \frac{a+b+c}{2}

<span>According to conditions:
</span>a = x
b = x+1
с = 2x-1

<span>Calculate the semiperimeter:
</span>s= \frac{x+x+1+2x-1}{2} = \frac{4x}{2}=2x

<span>Now we can compose and solve the equation according to Heron's formula:
</span>\sqrt{2x(2x-x)(2x-(x+1))(2x-(2x-1))}=x \sqrt{10}   \\  \sqrt{2x(x)(2x-x-1)(2x-2x+1)}=x \sqrt{10} \\  \sqrt{2x^2(x-1)(1)}=x \sqrt{10} \\  \sqrt{2x^3-2x^2}=x \sqrt{10}  \  \  \ |()^2 \\ 2x^3-2x^2=10x^2 \\ 2x^3-2x^2-10x^2=0 \\ 2x^3-12x^2=0 \ \ |:2 \\ x^3-6x^2=0 \\ x^2(x-6)=0 \\  \\ x^2=0 \\ x=0 \ \ \ \O \\ or \\ x-6=0 \\ x=6

<span>As a result, x = 6 is your answer.

Translate the graph according to the rule (x, y) → (x + 2, y).
IRISSAK [1]

(x, y) → (x, y + n) - translate the graph n units up

(x, y) → (x, y - n) - translate the graph n units down

(x, y) → (x - n, y) - translate the graph n units left

(x, y) → (x + n, y) - translate the graph n units right

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

(x, y) → (x + 2, y)

translate the graph 2 units right.

How many solutions are there to<br>the Equation below? 5(x+10)-25=54+25​
Snowcat [4.5K]

Answer:

54/5

Step-by-step explanation:

5(x+10)-25=54+25

5x + 50 - 25 = 54 + 25

5x + 50 - 25 = 79

5x + 25 = 79

5x = 79 - 25

5x = 54

x = 54/5
