Answer:
The properties of right angle triangle are as follows
- the hypotenuse is the longest side
- one angle is 90 degree then other angle will be also 90 degree.
Let S be the sum,
S = 2 + 4 + 6 + ... + 2 (n - 2) + 2 (n - 1) + 2n
Reverse the order of terms:
S = 2n + 2 (n - 1) + 2 (n - 2) + ... + 6 + 4 + 2
Add up terms in the same positions, so that twice the sum is
2S = (2n + 2) + (2n + 2) + (2n + 2) + ... + (2n + 2)
or
2S = n (2n + 2)
Divide both sides by 2 to solve for S :
S = n (n + 1)
Answer: step one is correct and the second step is incorrect
Step-by-step explanation:
First, we will convert the fraction and percentage to decimal
Then arrange from least to greatest
Bears 57% = 0.57
Tigers 5/8 =0.625
Mustangs = 0.65
Re-arranging from least to greatest
0.57, 0.625, 0.65
Bears, Tigers, Mustangs
