Which of these is a unit of density?
Naddika [18.5K]
<h3><u>Answer:- </u></h3>

\longrightarrow \textsf{The unit of density is\;}\sf kg/m^3

<h3><u>Solution</u> :-</h3>

\green{ \underline { \boxed{ \sf{Density =  \frac{Mass}{Volume}}}}}

\longrightarrowThe unit of mass is kg and unit of Volume is m³ . Since density is division of mass by volume , the corresponding units will also get divided and unit of density would come out to be kg/m³

<u>Some basic </u><u>derived </u><u>Units :- </u>

  • area => m²
  • volume cubic meter => m3
  • speed meter per second => m/s
  • acceleration => m/s²
  • mass density meter => kg/m3
  • specific volume cubic meter per kilogram m³/kg

An isosceles triangle with legs measuring 10 in and a vertex angle of 30 degrees.
Ulleksa [173]

Isosceles triangle is a triangle which has at least two of it's sides equal to each other.

<u>Explanation:</u>

In geometry, an isosceles triangle is a triangle that has two sides of equivalent length. Here and there it is determined as having precisely different sides of equivalent length, and at times as having at any rate different sides of equivalent length, the last form subsequently including the symmetrical triangle as an extraordinary case.

An isosceles triangle is a triangle with (in any event) two equivalent sides. In the figure over, the two equivalent sides have length and the staying side has length. This property is equal to two points of the triangle being equivalent.

Find two consecutive numbers whose squares differ by 33
stich3 [128]

Answer:

Two consecutive numbers whose squares differ by 33 are 16 and 17

Step-by-step explanation:

lets assume first number be x

since numbers are consecutive , so other number will be x + 1

From given information in question

(x + 1)² - x² = 33

⇒ (x² + 1² + 2x)  - x² = 33       [   since (a+b)² = a² + b² + 2ab ]

⇒ x² + 1² + 2x - x² = 33

⇒ 2x + 1 = 33

⇒ 2x = 33 - 1

⇒ x = 32/2 = 16

so one number is x = 16 and other number is x + 1 = 16 + 1 = 17

lets recheck our solution

17² - 16² = 289 - 256 = 33 , And since difference is 33 , two required consecutive numbers are 16 and 17.
