Bad White [126]

Answer:

4.9\%

Step-by-step explanation:

we know that

To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area

Let

x ----> the area of the hole

y ----> the area of the playing game

so

P=\frac{x}{y}

we have

y=16\ ft^2

<em>Find the area of the hole</em>

The area of the circle (hole) is equal to

A=\pi r^{2}

we have

r=1/2=0.5\ ft ----> the radius is half the diameter

assume

\pi =3.14

substitute

A=(3.14)(0.5)^{2}

A=0.785\ ft^2

<em>Find the probability</em>

P=\frac{x}{y}

we have

x=0.785\ ft^2

y=16\ ft^2

substitute

P=\frac{0.785}{16}

P=0.0491

Convert to percentage

0.0491*100=4.91\%

Round to the nearest tenth

4.9\%

Answer:

The simplified form is x\geq -99.

Step-by-step explanation:

Given : Expression \frac{x}{3}\geq -33

To find : The simplified expression ?

Solution :

Expression \frac{x}{3}\geq -33

Multiply 3 both side,

\frac{x}{3}\times 3\geq -33\times 3

x\geq -99

Therefore, the simplified form is x\geq -99.
