The ratio 2.5 metres to 60 centimetres can be written in the form 1:n find the valur of n

Maslowich

Answer:

The value of n is $\frac{6}{25}$

Step-by-step explanation:

we know that

1 m=100 cm

step 1

Convert 2.5 m to cm

2.5 m=2.5*100=250 cm

step 2

Find the ratio

$\frac{250}{60}=\frac{25}{6}$

Divide by 25 both numerator and denominator

$\frac{1}{\frac{6}{25}}$

therefore

The value of n is $\frac{6}{25}$

Solve for x. <br><br> Please help !

Ne4ueva [31]

Answer:

x = 37 1/2
x = 2

Step-by-step explanation:

Parallel lines divide transversals proportionally. I like to write the proportions so the variable is in the numerator. Then the solution is obtained by multiplying by the denominator of the variable term.

1. x/20 = (46 -16)/16

x = 20(30/16)

x = 37.5

2. (x +4)/13.5 = 4/9

x +4 = 13.5(4/9) = 6

x = 6 -4

x = 2

If the volume of a cubical box is 1728cm find its total surface area

Lera25 [3.4K]

Answer:

Step-by-step explanation:

The formula of a volume of a cube:

$V=s^3$

We have

$V=1728\ cm^3$

Substitute:

$s^3=1728\to s=\sqrt[3]{1728}\\\\s=12\ cm[/texbecause[tex]12^3=1728$

The formula of a surface area of a cube:

$SA=6s^2$

(6 square faces of a cube)

Substitute:

$SA=6(12^2)=6(144)=864\ cm^2$
