*PLEASE HELP MEEEEEE* You throw a dart at the board shown. Your dart is equally likely to hit any point inside the square board.

yawa3891 [41]

Answer:

19.63%

Step-by-step explanation:

The probability of scoring 8 points is the probability of getting a dart into the green circle.

That probability is equivalent to the area of the circle divided by the total area of the square board.

The area of the circle according to $A=\pi*r^2$ , is $25\pi$ cm squared

The area of the whole square board is one side squared: 20 squared = 400 cm squared

The probability is therefore equal to $25\pi/400 = \pi/16=0.19634=19.63%$ %

SOLVE FOR X IN THE DIAGRAM

$\orange{\underline{\huge{\bold{\textit{\green{\bf{FORMULA}}}}}}}$

SUM OF ALL ANGLES ON STRAIGHT LINE IS 180°

$\bold{ \pink{GIVEN :- }}$

ANGLES :- 5x , (x+54°),90

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

$5x + x + 54+ 90 = 180° \\ 6x + 144 = 180° \\ 6x = 180 - 144 \\ x = \frac{36}{6} \\ x = 6 \: \: ans$

If 2x+4 = (x²)²÷2 then what is x?

Leviafan [203]

Answer:

Below.

Step-by-step explanation:

2x+4 = (x²)²÷2

2x + 4 = x^4/2

x^4 = 4x + 8

x^4 - 4x - 8 = 0

We can try trial an error to solve this

Looks like x = 2 fits it:

2^4 - 4(2) - 8

= 16 -8 -8 = 0

so x = 2 is one solution.

I can't find any other solution among other integers.

To find the other solutions you can draw a graph manually or by using software.

There will be either 1 or 3 more real solutions.

I used software to draw the graph and found one other solution:

x = -1.296
