Answer:

Atomic mass

Step-by-step explanation:

That number is the atomic mass of the element. It is also the same numerical value as the molar mass, which is the mass of 1 mole of the element.

So, in this case, sodium (Na) has an atomic mass of 22.99 atomic mass units (amu).

Hope this helps!

Answer: Correct Answer is 4th option , 28


Step-by-step explanation:


We can find the measure of the angle using the tangent.


We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.


So, Tan of angle T = RG / RT

or, Tan of angle T = 8/15

or, angle T = tan inverese of 8/15

or, angle T = 28.07


So, angle T rounded to nearest degree = 28


Hope this helps.


Thank you.

PLS HELP I WILL GIVE YOU A BRAINLIST AND A THANK YOU!!!!

Answer:

75

Step-by-step explanation:

We have a 90 degree angle and a 15 degree angle that add up to 105. The angle that is missing can be found by doing 180 - 105 = 75 (since it's a straight line). X is vertical from the 75 degree angle, so 75 is your answer.

Lakshmi has 11 more20-rupee notes than 10-rupee notes. If she has Rs 550 in total, how many notes of each kind does she have?
olganol [36]

Answer:

10rupee notes are 11

20rupee notes are 22

Step-by-step explanation:

Let 10-rupee note be x

20-rupee note will be x + 11

The equation will be

10x + 20(x + 11) = 550

10x + 20x + 220 = 550

30x = 330

x = 330/30 = 11 = 10rupee notes

y = 11+11 = 22 = 20rupee notes
