Answer:
25 boys.
Step-by-step explanation:
To solve this problem, first add the two parts of the ratio. 9 + 5 = 14. Then divide 70 by 14 to get 5. Since the total is 5 times the ratio total, multiply both sides of the ratio by 5. The result is 45 : 25. If you add them together, you get a total of 70. Therefore, there are 25 boys in the class.
Answer:
x² + y² +10x -6y - 69 = 0
Step-by-step explanation:
We need to write the standard equation of circle with , centre (-5,3) and radius 10 unit . The Standard equation of the circle ⭕ is ,
=> ( x - (-5))² + (y -3)² = r²
=> ( x +5)² + (y-3)² = 10²
=> x² + 25 + 10x + y² +9-6y = 100
=> x² + y² +10x -6y + 31 = 100
=> x² + y² +10x -6y - 69 = 0
<h3>• Hence the equation of the circle is x² + y² +10x -6y - 69 = 0.</h3>
