Answer»
Let length and breadth of rectangle be 3x and 4x. we know that, where,
➻ 2( 3x + 4x ) = 70 ➻ 7x = 70/2 ➻ 7x = 35 ➻ X = 35/7 ➻ x = 5 Hence, ● Length of rectangle 3x = 3× 5 = 15 ● Breadth of rectangle 4x = 4 × 5 = 20 ━━━━━━━━━━━━━━━━━━━━━━━━━ ⠀⠀༒Some formulas :- ⪼ Area of rectangle = l × b ⪼ Perimeter of rectangle = 2(l + b) ⪼ Length of rectangle = Area/Breadth ⪼ Breadth of rectangle = Area/length ⪼ DIAGONAL of rectangle = √l² + b² ━━━━━━━━━━━━━━━━━━━━━━━━━ |

A^b how much indicator ? |
|
Answer» At a low pH, a weak acid indicator is almost entirely in the HIn form, the color of which PREDOMINATES. As the pH increases, the intensity of the color of HIn decreases and the equilibrium is pushed to the right. THEREFORE, the intensity of the color of In- increases. An indicator is most effective if the color change is distinct and over a small pH range. For most INDICATORS the range is within ±1 of the pKln value. Plz mark me a Brainliest answer |

11. The denominator of a rational number is 2 less than twice the numerator. If numerator anddenominator are increased by 1 each the rational number becomes4/5Find the number. |
|
Answer» -6/11 or 6/11 Answer Step-by-step explanation: Let denominator = x So, numerator = 2 - 2x In the question , if they are increase by 1 then the , denominator = x + 1 numerator = 2 - 2x + 1 (2 - 2x + 1) / x + 1 = 4 /5 = (3 - 2x) / + 1 = 4/5 [ in 2 - 2x + 1 , 2 + 1 = 3.] = 5(3 - 2x) = 4(x + 1) [cross - MULTIPLICATION between (3 - 2x) / x + 1 & 4/5.] = 15 - 10x = 4x + 4 = -10 x - 4x = + 4 - 15 [ +4 x moves yo LHS and becomes -4 x , likewise, +15 moves to RHS and becomes -15. Because x terms cannot be subtracted by non - x terms. ] = -14 x = -11 Therefore x = -11/-14. So, now we will substitute the ANSWERS., denominator = 11/14 and, numerator = 2 - 2 x 11/14 = 2 - 11/7 [ we divided 14 by 2 which is EQUAL to 7.]
Now, numerator = 3/7
3/7÷11/14 [ as numerator = 3/7 and 11/14 = denominator.] It can also be written as (3/7)/(11/14). 3/7 x 14/11 [ as we know that in multiplication of rational numbers the second number is reversed .] = 3/1 x 2/11 = 6/11 THEREFORE , THE NUMBER IS 6/11. I HOPE IT WILL HELP YOU. And , if it helped then plz mark it as the brainliest answer.plz. |
