Consider the rational numbers 4/13 and 3/10.

omeli [17]

I believe 4/13 is the bigger number because 0.36>0.3
I suggest using a calculator to check but I believe 3/10 is the rational number because it terminates and doesn't repeat

Find the area and the circumference of a circle with radius 6 m.

Ratling [72]

Answer:

(a) 113.04m²

(b) 37.68m

Step-by-step explanation:

(a)

Area = πr²

=π(6)²

=36π

=113.04m²

(b)

Circumference = 2πr

2π(6) = 12π

=37.68m

Which system of inequalities represents region Z?

ANTONII [103]

Answer:

The system of inequalities is

$y\geq 3x-2$

$y$

Step-by-step explanation:

step 1

Find the equation of the solid blue line

Let

$A(0,-2), B(1,1)$

Find the slope of AB

$m=(1+2)/(1-0)=3$

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

$m=3$

$b=-2$ ----> the point A is the y-intercept

substitute

$y=3x-2$ -----> equation of the solid blue line

The solution of the inequality is the shaded area above the solid line

therefore

The first inequality is

$y\geq 3x-2$

step 2

Find the equation of the dashed red line

Let

$C(0,2), D(5,1)$

Find the slope of CD

$m=(1-2)/(5-0)=-1/5$

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

$m=-1/5$

$b=2$ ----> the point C is the y-intercept

substitute

$y=-(1/5)x+2$ -----> equation of the dashed red line

The solution of the inequality is the shaded area below the dashed line

therefore

The second inequality is

$y$

The system of inequalities is

$y\geq 3x-2$

$y$
