Answer» $Answer :$ The statement that is not correct with reference to REFLECTION of light by a plane SMOOTH SURFACE is: (2) The angle of reflection is the angle between the reflected ray and the plane of the mirror. When a ray of light is incident on a plane surface, it gets reflected. The angle with which the ray strikes the surface is equal to the angle with which it is reflected BACK. The angle of incidence is the angle between the incident ray and the normal at the point of incidence. Similarly, The angle of reflection is the angle between the reflected ray and the normal. All the three rays i.e. normal, incident ray and reflected ray lies on the same plane and at the same point.

diary entry in about 150-200 words describing how your family and other families in the

Step-by-step explanation:

Fear is defined as “a feeling of concern about somebody's safety or about

self protection and fear itself misplaced can lead one towards self sabotage

and destruction. Fear arises with the THREAT of harm, either physical,

protection against danger. Fear by itself is an emotion which can be a tool for

self - protection. It helps one , avoid imminent danger. It is the fear of being

run over that makes people alert before crossing the road.

Wearing masks,

sanitizing the hands, has been a protective measure that one is taking against

the deadly corona virus attack. Fear alerts us. In some circumstances we

become extra alert and extra aware. The fear of a "If I don't save for a rainy

day, I will have no money, so I better save now."is a rational protective fear

By the given condition , ⅓× x = ½ ( 100 - x) $\longrightarrow\sf{x/3 = 100/2 - x/2}$ $\longrightarrow\sf{x/3 = 100-x/2}$ $\longrightarrow\sf{x×2/3= 100-x}$ $\longrightarrow\sf{2x/3= 100-x}$ $\longrightarrow\sf{2x= 3(100-x)}$ $\longrightarrow\sf{2x= 300- 3x}$ $\longrightarrow\sf{2x + 3x = 300}$ $\longrightarrow\sf{5x = 300}$ $\longrightarrow\sf{x = 300/5}$ $\longrightarrow\sf\pink{x = 60 }$ Therefore first part is x that is 60 Therefore second part is 100 - x $\longrightarrow\sf{100-60}$ $\longrightarrow\sf\pink{40}$ Therefore the second part is 40 @MissOxford

Divide ₹100 into two parts such that ⅓rd of the first and ½ of the second are equal. (explain in detail)

Answer»

QUESTION. :

Divide ₹100 into TWO PARTS such that ⅓rd of the first and ½ of the second are equal

Answer :

$\sf\purple{Given}$

Let ONE part be x .

Therefore other part = 100 - x.

By the given condition ,

⅓× x = ½ ( 100 - x)

$\longrightarrow\sf{x/3 = 100/2 - x/2}$

$\longrightarrow\sf{x/3 = 100-x/2}$

$\longrightarrow\sf{x×2/3= 100-x}$

$\longrightarrow\sf{2x/3= 100-x}$

$\longrightarrow\sf{2x= 3(100-x)}$

$\longrightarrow\sf{2x= 300- 3x}$

$\longrightarrow\sf{2x + 3x = 300}$

$\longrightarrow\sf{5x = 300}$

$\longrightarrow\sf{x = 300/5}$

$\longrightarrow\sf\pink{x = 60 }$

Therefore first part is x that is 60

Therefore second part is 100 - x

$\longrightarrow\sf{100-60}$

$\longrightarrow\sf\pink{40}$

Therefore the second part is 40

Answer»

Answer:

i. (X + 3) (x + ⅓)

= $\Large \: x² + \frac{x}{3} + \: 3x + <klux>1</klux>$

= $\Large \: x² + \frac{10x}{3} + \: 1$

iii. (q² + 5)(q² - 1)

= q⁴ + 4q² - 5

iv. (x³ + 2)(x³ - 3)
