The perimeter of a rectangular pool is 72 meters. If the length of the pool is twice its breadth. Its length is_________.

Answers

Answer:

Length = 18 meters

Step-by-step explanation:

Let the length of the rectangular pool = l meters

And breadth of the pool = w meters

Perimeter of the rectangular pool = 2(l + 2w)

Since, perimeter of the rectangular pool is 72 meters.

2(l + 2w) = 72

l + 2w = 36 --------(1)

If length of the pool is twice of its breadth,

l = 2w

w = [tex]\frac{l}{2}[/tex] -------(2)

By substituting the value of 'w' from equation (2) to equation (1),

[tex]l+2\times{\frac{l}{2}}=36[/tex]

2l = 36

l = 18 meters

Answers

Answer:

Step-by-step explanation:

Let the number be represented = x

Seven times the sum of a number and six subtracted from four times the number results in negative twenty

7 ×(x + 6) - 4 x x = -20

7(x + 6) - 4x = -20

7x + 42 - 4x = -20

7x - 4x = -20 - 42

3x = -62

x = -62/3

x = -20.67

The number is -20.67

Sry when Its wrong

Answer:

sin• = √13/7

tan•= -√13/4

Step-by-step explanation:

sin2•+ cos2• = 1

sin• = √1-cos2•

sin•= √1-(-4/7)2

sin•= √1-16/49

sin•= √ 49-16/49

sin•= √ 13/ 49

sin•= √13/7

tan• = sin•\cos•

= √13/7/-4/7

= -√13/4

What is the solution to this inequality?

−4x−8>−20

Answers

Answer:

x < 3

Step-by-step explanation:

−4x − 8 > −20

Add 8 to both sides.

-4x > -12

Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

-4x/(-4) < -12/(-4)

x < 3
