Answer: 27
Step-by-step explanation:
The given sequence : 13, 24, 35, ....
Here, first term : a= 13
Common difference: d=24-13 =11
The nth term of arithmetic sequence is given by :-
It is given that the nth term is 299, so put 
Subtract 13 from both sides , we get
Divide both sides by 11, we get
Add 1 on both sides , we get
Hence, the value of n= 27
Answer:
the area of the striped rectangle= length ×breadth
Hello,
Let y=sin^(-1)(12/13.
==>sin y=12/13
==>cos y=√(1-(12/13)²)=√(25/169)=5/13
Answer 5/13
Answer:
-12a - 48
Step-by-step explanation:
you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48
since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.
Answer:
24 cm
Step-by-step explanation:
Perimeter of equilateral triangle = 12 cm
Therefore, measure of one side of equilateral triangle = 12/3 = 4 cm
Perimeter of hexagon = 6 * measure of one side of equilateral triangle
= 6 * 4 = 24 cm
