Answer:

the number = 8/5 or 1 3/5 or 1.6

Step-by-step explanation:

n = the number

5/2n - 11 = 4

5/2n - 11 + 11 = 5 / 2n

5/2n = 4

5/2n / 5/2 = n

4 / 5/2 = 8/5

a square has a perimeter given by the expression 16x + 32y . Write an expression for the length of one side of the square

Lady_Fox [76]

Perimeter=4*side so

side=p/4 and we are told p=16x+32y so

s=(16x+32y)/4

s=4x+8y

s=4(x+2y)

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

$4.9\%$
