Answer:

Second Term : T2 = (2)² - 3 = 1

Third Term : T3 = (3)² - 3 = 6

Tenth Term : T10 = (10)² - 3 = 97

What is 20% of 40, work it out

Darina [25.2K]

Hey there

Answer:

20% of 40 is 8 .

Step-by-step explanation:

In this question we are given a number that is 40 . And we have asked to find 20% of it .

Solution : -

$\longmapsto \qquad \: \: 20\% \times 40$

We know that ,

Percent ( % ) represent 1/100

So ,

 $\longmapsto \qquad \: \: ( 20 \times \dfrac{1}{100}) \times 40$ 

or ,

 $\longmapsto \qquad \: \: \dfrac{20}{100} \times 40$ 

Now cancelling zero :

$\longmapsto \qquad \: \: \dfrac{2 \cancel{0}}{1 \cancel{0} \cancel{0}} \times 4 \cancel{0}$

We get ,

$\longmapsto \qquad \: \: 2 \times 4$

$\longmapsto \qquad \: \: \blue{\underline{\boxed{\frak{8}}}} \quad \bigstar$

Therefore , 20% of 40 is 8 .
