Answer:
Step-by-step explanation:
area of the square =10*10=100
area of the circle =pi r^2=pi*1^2=3.142
part a
p(hitting the circle =3.142/100=0.03142 Which is closer to 0
part b
p( hitting the white portion ) =1-0.03142=0.96858 which is closer to 1
Answer:
Use the information given to write an equation in standard form.
Slope is -3, and (0, -4) is on the line.
Step-by-step explanation:
Answer:
1x^2+8x
Step-by-step explanation:
Combine like terms
6x^2+(-5x^2)+10x+(-2x)+(-1)+1
1x^2 +8x+0
And there you go
The ratio of the surface areas are 361/81.
surface area is a 2D measurement.
similarity is a 1D ratio.
square root of 361/81 is 19/9.
<span>20 - 2 * 3^2
Remember PEMDAS.
Parentheses
Exponents
Multiplication/Division
</span>Addition/Subtraction
There are no parentheses, but there is an exponent. So first you must do 3^2.
<span>20 - 2 * (3*3)
</span>20 - 2 * 9
Next is multiplication/division. Multiply -2 by 9.
20 - 2 * 9
20 - 18
Lastly, you subtract.
20 - 18
2
The answer is 2.
