Vulgar fractions are fractions with denominator not 10,100,1000 and etc. Ex:45/56,89/90 etc

## Ans 2:

Class : Class 7
A fraction whose deno minator is a whole number,other than 10,100,1000, etc., is called a vulgular fraction. Ex. 2/9, 4/13 ,etc.,are vulgular fraction

## Ans 3:

Class : Class 9
The fraction whose denominator is a whole number other than 10,100,1000 is called vulgar fraction. for ex 5/7,8/6,6/8.

yeah the answer is 1000 trees. bro because see 4km 800m = 4800 by multiply we had converted it to metres to solve the sum. then step2= we will divide it to 9.6 because it has said to have intervals and to find the intervals we need to divide as we dont know how is the length is by after the interval and after the answer will be 500 step3= then the trees are planted both sides of the roads so multiply with or by 2 and the answer is 1000 trees.

Hypotenuse=(side1)*2+(side2)*2

Class : Class 9
(H)2=(P)2+(B)2

AB2+BC2=AC2 THIS MEANS THAT IN A TRIANGLE WHEN WE ADD THE SQUARE OF THE BASE AND PARALLEL ANGLE IT WILL ALWAYS BE EQUAL TO THE HYPOTENUSE.

Class : Class 8
a2+b2=c2

Hypotenuse=base×base+hieght×height Base=hypotenuse×hypotenuse -height ×height Height=base×base - hypotenuse×hypotenuse

Asquare+B square = C square (hypotenuse)

## Ans 7:

Class : Class 7
Square of hypotenuse=Square of its legs

## Ans 8:

Class : Class 7
The pythagoras' theorem states that the square of the hypotenuse is equal to the sum of the square of the other 2 sides. The equation would be hyp2=S12+S22 note: the 2 is the power of two

## Ans 9:

Class : Class 10
a = 1 side, b = another side, c = hypotenuse (the longest side). The formula is: a2 + b2 = c2 (the two means squared, not multiplied by two). The formula only works in right-angled triangles.

Class : Class 7
(H)2=(P)2+(B) 2

Class : Class 7
A2+B2=C2

## Ans 12:

Class : Class 10
Hypotenuse^2= P^2 + B^2 Here, P=perpendicular height and B=base.

Class : Class 7
(H)2=(P)2+(B) 2

## Ans 14:

Class : Class 9
square of hypotenuse=sum of square of other 2 legs in a right angled triangle

## Ans 15:

Class : Class 8
square of base + square of perpendicular side = square of hypoteneuse

## Ans 16:

Class : Class 7
(H)2=(P)2+(B) 2

Absolute value means you have to ignore the plus / minus sign. 4*7+3*(2-5) = 4*7+3-3 = 28
