Answer:
Johnny needs to score 98 on third test to raise average to 94
Step-by-step explanation:
Given that average of two tests is 92.
The score of next test has to be found that means there will be a total of 3 tests.
The average will be:
It is also given that he has to raise his average to 98
We have to use the average formula for finding the third value
So,
Hence,
Johnny needs to score 98 on third test to raise average to 94
Step-by-step explanation:
x² + y² + 2x + 6y = 39
( x + 1)² - 1 + ( y + 3)² - 9 = 39
( x + 1)² + ( y + 3)² - 10 = 39
(x + 1)² + (y + 3)² = 49
radius= √49 = 7
center = ( -1 , -3)
x² + y² - 4x - 2y + 1 = 0
(x - 2)² - 4 + (y - 1)² -1 + 1 = 0
(x - 2)² + (y - 1)² = 4
radius = √4 = 2
center = (2 , 1)

Answer:
11 m
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 = s^2
Take the square root of each side
sqrt(121) = sqrt(s^2)
11 = s
