X=162, if you multiply 18*9 which is the way to get the answer you get 162
Answer:
The sum of the first 650 terms of the given arithmetic sequence is 2,322,775
Step-by-step explanation:
The first term here is 4
while the nth term would be ai = a(i-1) + 11
Kindly note that i and 1 are subscript of a
Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula
Sn = n/2[2a + (n-1)d)
Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.
Plugging these values, we have
Sn = (650/2) (2(4) + (650-1)11)
Sn = 325(8 + 7,139)
Sn = 325(7,147)
Sn = 2,322,775
The perimeter is 20 units
Step-by-step explanation:
The end-point of a side of square can be used to calculate length of a side. And the side will be used to calculate the perimeter.
Given
(3,-1) and (7,2)
Let
(3,-1) = (x1,y1)
(7,2) = (x2,y2)
We have to calculate the distance
The formula for distance is:
Let s be the side of a square
then,
The side of square is 5 units. Then,
The perimeter is 20 units

Answer:
The correct option for the answer is C.) $3.29 / $2.96
Step-by-step explanation:
i) national average for a gallon of gas = $2.74
ii) for transportation New York is 1.2 times the National average
therefore one gallon of gas in New York will cost = 1.2 $2.74 = $3.29
iii)for transportation Los Angeles is 1.08 times the National average
therefore one gallon of gas in New York will cost = 1.08 $2.74 = $2.96
Therefore you should expect to pay for gas in New York versus Los Angeles C.) $3.29 / $2.96
