A game has a circular playing area in which you must hit a ball into a circular hole. The area of the playing area is 16ft2. The

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

$P=\frac{x}{y}$

we have

$y=16\ ft^2$

Find the area of the hole

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

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

$A=0.785\ ft^2$

Find the probability

$P=\frac{x}{y}$

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

$4.9\%$

Use in the elimination mentioned for this problem 6x+5y=11 x+y =6

Oliga [24]

Answer:

{x = -19 , y = 25

Step-by-step explanation: System solved by elimination

Solve the following system:

{6 x + 5 y = 11 | (equation 1)

{x + y = 6 | (equation 2)

Subtract 1/6 × (equation 1) from equation 2:

{6 x + 5 y = 11 | (equation 1)

{0 x+y/6 = 25/6 | (equation 2)

Multiply equation 2 by 6:

{6 x + 5 y = 11 | (equation 1)

{0 x+y = 25 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{6 x+0 y = -114 | (equation 1)

{0 x+y = 25 | (equation 2)

Divide equation 1 by 6:

{x+0 y = -19 | (equation 1)

{0 x+y = 25 | (equation 2)

Collect results:

Answer: {x = -19 , y = 25

One fifth of sum of two angles is 24 and their diffetence is 14 find the two angles

Serggg [28]

Answer:

Angles are $67^0,53^0$

Step-by-step explanation:

Let the angles be $x,y$

One fifth of sum of two angles is 24

$\frac{x+y}{5} =24\\\\x+y=120$

The difference is $14$

$x-y=14$

$2x=134\\\\x=67^0$

$y=120-67\\\\=53^0$
