slope (m)= -a/b m= -1/2

why you are reply me wrong answer you are mc bc

6 men do work in 7 days1 men do work = 7/6 daythen21 men work same work = 7/6 * 21 = 49/2 = 24.5 days

6 men do in 7 days=42 men*days21 men can do in days=42/21=2 days

6 man together perform d work in 1 day is = 1/6+1/6= 2/6 parts3 man 1 day work 1/63 man 2 days work 2/6Remaining (1-2/6)=2/3 parts2/6 parts completed in 1 day2/3 parts wil b completed in = 2 days

distance between the foot of the tree and the broken part of the tree that touches the ground = 30 mlet ,the height ofstanding part of the tree be = htheheight of fallen part (forms hypotenuse) be = xthen the total height of the tree will be = h + xnow,tan 30 = h/30 m 1/√3 = h/30 m 30/√3 = h ⇒ h= 30/√3 m ..... 1similarly,cos30 = 30 m/ x √3/2 = 30/ x√3x = (30)2√3x = 60 m⇒x = 60 /√3 m ......2 (we now have both value of h and x ) on adding equation1 & 2 :⇒h + x = 30 /√3 +60 /√3 =90 /√3 m = 60√3 mso , the total height of the tree is 60√3 m .

So to find cube root easily ( works good for perfect cube)

1. Note the unit digit of given number.2. Think of number from 1 to 9 whose cube have same unit digit.3. Use some intuition to find the nearest number with it.

Ex:

cube root of 10648So,2³ is 8 So last digit of cube root must be 2we know cube of 20³ = 8000So, cube root must be 20 to 25,Therefore only possible number is 22.whose cube is 10648.

Fractions whose denominators are not same those are unlike fractionHence example of unlike fraction will be3/5,1/2,4/8,etc

Like Fractions:The fractions having the same denominators are known as like fractions.

We know that fractions such as 2/5, 3/5, 5/5, 7/5, 9/5, ….etc., arelike fractions

Unit Fractions:The fractions having one (1) as their numerator are called unit fractions.

1/3, 1/5, 1/7, 1/9, …………, etc., areunit fractions.

The fractions with different denominators are calledunlike fractions.

Examplesunlike fractions are:

(a) (1/2, 1/4, 2/3, 5/6)

(b) (3/8, 2/3, 3/5, 2/7)

(c) (1/9, 2/7, 3/4, 2/5).

A. 8x², x² and -9x²y B. -3b², b² and 9b³

insulators are made of glass, porcelain or composite polymer materials so A is the right option

Step-by-step explanation:

A1=2x5=10

A2=2x(5+3)=16

A3=2x(5+3+3)=22

S10=10/2(2x10+(10-1)6)

=5(20+9x6)

=5x(20+54)

=5x74

S10=370

So the answer is 370

The answer of this question is 320 papads

335x15=5025 potato papads

335x15=5025 potato papads

(x^4*y^4)^1/4 ÷ (x^3*y^3)^1/3

= (xy)^4*1/4 ÷ (xy)^3*1/3

= (xy) ÷ (xy)

Given AP 3, 6, 9......897

Now, reverse the AP897,............. 9, 6, 3

We have to find 9th term of reversed AP which is equal to 9th term from last for given AP

For reversed AP,First term a = 897, common difference = 6 - 9 = - 3

9th terma9 = a + 8d = 897 + 8*(-3)a9 = 897 - 24 = 873

Therefore, 9th term from last is 873
