can you help with this is it right or wrong

a) The length of shelf in centimeters is 72 cm

b) The length of shelf in metres is 0.72 m.

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.

Given:

A shelf measures 720 mm long.

a) As 1 cm = 10 mm

So, the length of shelf in centimeters

= 720 /10

= 72 cm

b) As 1 m = 1000 mm

So, the length of shelf in meters

= 720 /1000

= 0.72 m

[tex]\boxed{\textsf{ The amount shared by Nandi is \textbf{ Rs 500. }.}}[/tex]

[tex]\boxed{\textsf{ The amount shared by Thabo is \textbf{ Rs 1,000. }.}}[/tex]

Step-by-step explanation:

Given that Nandini and Thabo share Rs 1500 in the ratio 1:2 . And we need to find how much each gets . So lets take the given ratio be 1x :2x . Now here we can find the share of both as ,

[tex]\qquad\boxed{\boxed{\sf Share =\dfrac{ Ratio \ number }{Sum \ of\ ratio\ nos. }\times Amount }}[/tex]

Hence here the sum of ratio numbers would be 1+2 = 3 . Here the ratio number of Nandi is 1 and that of Thaboo is 2 . So ,

Share of Nandi :-

[tex]\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Nandi)}= Rs\ 500 }}}[/tex]

[tex]\rule{200}2[/tex]

Share of Thabo :-

[tex]\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Thabo)}= Rs\ 1,000 }}}[/tex]

The expression (2x-3)(2x-3) can be written as (2x-3)² or 4x² - 12x + 9 after expanding by using the identity (a - b)² = a² -2ab + b²

It is defined as the combination of constants and variables with mathematical operators.

We have given an expression:

= (2x-3)(2x-3)

After multiplication:

= (2x-3)²

We can also expand the above expression by using the identity:

(a - b)² = a² -2ab + b²

= 4x² - 12x + 9

Thus, the expression (2x-3)(2x-3) can be written as (2x-3)² or 4x² - 12x + 9 after expanding by using the identity (a - b)² = a² -2ab + b²

Step-by-step explanation:

sides opposite to equal angles are equal in length :

angle45 = angle 45

r = s

by Pythagoras theorem :

r² + s² = (9√2 )²

s²+s²= 9 × 9 × 2

2s²= 9× 9×2

s²= 9 × 9

s= √9× 9

s = 9

r= s = 9 units .

5x + 70 = 320

Step-by-step explanation:

We know that Carmine paid an electrician a certain amount per hour, we also know that they worked for 5 hours. Therefore we have 5x.

He also got paid 70 for parts, meaning an extra $70

And we know that we have the total charge and that the main point of this question is to determine how much the electrician was paid per hour.

Therefore :

5x + 70 = 320

x = -4

Step-by-step explanation:

Lets divide both the sides by -3.

[tex] = > \frac{ - 3x}{ - 3} = \frac{12}{ - 3} [/tex]

[tex] = > x = - 4[/tex]

x= -4

-3x=12

divide x by -3 and do the same on the other side

12÷(-3)= -4

hence, x= -4
