Show that the line 4y=5x-10 is perpendicular to the line 5y+4x=35 plz quickly answer

Answer»

concept :-

When TWO lines are perpendicular , then the product of their slopes is equivalent to -1.

Equation of line in the form y = mx + C

have m as slope of line and c as y-intercept.

Solution:-

GIVEN equations of lines are-

4y = 5x-10

or, y = (5/4)x - (5/2). .....(i)

5y + 4x = 35

or,y = (-4/5)x + 7. .....(II)

Let m and n be the slope of equations i and ii, respectively.

Here, m = 5/4

n= -4/5

therefore, m× n = -1

Hence, the lines are perpendicular.

Answer» $\huge\underline\bold\red{AnswEr}$ 11 ====== answer Since 7 games is equal to 35% 1 game is equal to 5% Or 5% is equal to 1 game Therefore 100% is equal to 20 games (by multiplying both SIDES with 20, your target should be to MAKE that 5% to 100% which is POSSIBLE by multiplying with 20 so you will have to do the same by multiplying 1 with 20) answer 12 → Let the salary before increment = x increment = 20 % of x => 20 /100 × x => x/5 => given that if his new salary is rs. 30600 => the new salary is ALSO = x + x/5( the increment in the salary ) => 6x/5= 30600 => 6 x = 30600× 5 ==> x= 30600×5/6 x= 25500

34.

Please solve all these questions... no spam otherwise I will report ur answer..

Answer»

$\huge\underline\bold\red{AnswEr}$

11 ====== answer

Since 7 games is equal to 35%

1 game is equal to 5%

Or 5% is equal to 1 game

Therefore 100% is equal to 20 games (by multiplying both SIDES with 20, your target should be to MAKE that 5% to 100% which is POSSIBLE by multiplying with 20 so you will have to do the same by multiplying 1 with 20)

answer 12 →

Let the salary before increment = x

increment = 20 % of x

=> 20 /100 × x

=> x/5

=> given that if his new salary is rs. 30600

=> the new salary is ALSO = x + x/5( the increment in the salary )

=> 6x/5= 30600

=> 6 x = 30600× 5

==> x= 30600×5/6

x= 25500

A Piece of wire is used to make circles of the following pattern.The radius of the first circle is ‘ r ‘ cm and increased by 1 cm successively.Find the length of the wire that is required to make 5 such circles.(take π= 22/7)

Answer»

Given : The radius of the FIRST circle is ‘ R ‘ cm and increased by 1 cm successively

To find : the LENGTH of the wire that is required to make 5 such circles.(take π= 22/7)

Solution:

radius of 1st circle = r cm

radius of 2nd circle = r + 1 cm

radius of 3rd circle = r + 2 cm

radius of 4th circle = r + 3 cm

radius of 5th circle = r + 4 cm

Perimeter of circle = 2π* Radius

Total wire required = 2π ( r + (r + 1) + (r + 2) + (r + 3) + (r + 4))

= 2π(5r + 10)

= 10π(r + 2)

= 10 (22/7)(r + 2)

= 220(r + 2)/7 cm

10π(r + 2) cm or 220(r + 2)/7 cm is the length of the wire that is required to make 5 such circles
