Answer:
The answer to your question is Area = 49n² - 70n + 25
Step-by-step explanation:
Data
Length of the side = 7n - 5
Formula
Area of a square = side x side
Process
1.- Substitute values
Area = (7n - 5)(7n - 5)
2.- Expand
Area = 49n² - 35n - 35n + 25
3.- Simplify
Area = 49n² - 70n + 25
4.- The polynomial is 49n² - 70n + 25
Answer:
X = 119, Y = 61, Z = 119
Step-by-step explanation:
These are supplementary angles and equal 180.
180 - 61 = 119
Opposite angles are congruent
Answer:
very less
Step-by-step explanation:
When rolling a fair 6 sided die 5 times there are 6^5 possible combinations.
Of those, there are 5 ways to roll exactly four sixes, and each of those ways have 5 possible results on the die which has not rolled a six, plus there is 1 way to roll five sixes. 5*5+1=26 combinations with at least four sixes.
Now, take the number of results which fit your conditions, divide by the number of possible results and you get your answer: 26/7776 which can be reduced to 13/3338, a bit less than 0.4%
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
