60% of 90

= (60/100) x 90

= 6/10 x 90 = 54.

Half of 100 = (1/2) x 100 = 50.

Therefore 60% of 90 is greater.

(90/100) x 60 = 54
60% of 90 = 54.
(100/100) x 50 = 50
50% of 100 = 50

<em>60% of 90 is bigger than 50% (half) of 100. </em>

The variable x varies directly as the cube of y, and y varies directly as the square root of z. If x equals 1 when z equals 4, w

Aloiza [94]

Answer:

Step-by-step explanation:

According to the question,

$x$ ∝ $y^3$ .......(1)

$y$ ∝ $\sqrt{z}$ .......(2)

From equation 1,2 let constant of proportionality be $k1,k2$ respectively.

⇒ $x=k1(y^3)$ .......(3)

⇒ $y=k2(\sqrt{z} )$ .......(4)

From the above equations putting 4 into 3,

$x=k1((k2\sqrt{z})^3) =k1.k2^3.(\sqrt{z})^3$

Let the new constant to the above equation be $k3$ ,

$x=k3(\sqrt{z})^3$

Given,if x=1, when z=4

$1=k3(\sqrt{4} )^3=k3(8)$

⇒ $k3=\frac{1}{8}$

Now if x=27, then z=?

$27=\frac{1}{8} (\sqrt{z} )^3$

⇒ $(\sqrt{z} )^3=27(8)$

⇒ $\sqrt{z}=3(2)=6$

$z=36$

The width of a rectangle is 9 centimeters greater than the length. Find the dimensions of the rectangle if the perimeter is 66 c

g100num [7]

Answer: Length = 12cm , width = 21cm

Step-by-step explanation:

Let the length be x , then the width is x + 9, That is

Length = x

Width = x + 9

The formula for calculating the perimeter of a rectangle is given by:

Perimeter = 2 ( Length + Width )

substituting the values , we have :

66 = 2 ( x + x + 9 )

66 = 2 ( 2x + 9 )

divide through by 2

66/2 = 2x + 9

33 = 2x + 9

subtract 9 from both sides

33 - 9 = 2x

24 = 2x

divide through by 2

therefore :

x = 12

This means that

Length = 12cm

Width = 12 + 9 = 21 cm
