Answer:
b. 495
Step-by-step explanation:
Given
15, 21, 27, 33, 39, ...., 75
Number of terms = 11
Required
Evaluate
To evaluate means to add up all term of the series above;
The first step is to determine if the series is arithmetic or exponential;
If its arithmetic, then the difference between successive terms must be equal;
In other words;
21 - 15 = 27 - 21 = 33 - 27 = 39 - 33 = 6
<em>Since the result of the above expression gives 6, then it is an arithmetic series;</em>
<em></em>
The sum of n terms of an arithmetic series is calculated as this
Where n = 11
a = First term = 15
T_n = Last term = 75
The formula becomes
Hence, the series when evaluated is 495
Answer:
Step-by-step explanation:add 4 to the side that has "13" then you will get "17" then divided -7 from x and "17"and your answer is x=idk
Answer: The four angles will fit together at a point with no gaps.
Step-by-step explanation:
Given: The ratio of four angles 2:3:4:11.
Let the angles be 2x , 3x, 4x and 11x.
Larget angle= 11x
As per given,
Then,
All angles are :
Sum of all angles = they
Hence, the four angles will fit together at a point with no gaps.
