is it B....????
Answer:
Step-by-step explanation:
No of students study math = 3/5 of 50 = 30
No of students study English = 3/10 of 50 = 15
Total = 30 + 15 = 45
Remaining students = 5
No of students study geography = 5
Fraction of geography to whole class = 5/45 = 9
Would it like.. not be C?? Im guessing its C (:
The equation of a circle centred at point (m,n) and radius r is given by
<span>(x-m)² + (y-n)² = r²
</span>-------------------------------------------------------------
Centre = (4,3)
radius = 5
Equation:
(x - 4)² + (y - 3)² = 5²
⇒ x² - 8x + 16 + y² - 6y + 9 = 25
⇒ x² + y² - 8x - 6y + 25 = 25
⇒ x² + y² - 8x - 6y = 0
The equation of the circle is x² + y² - 8x - 6y = 0
Hope it helps!
The picture is too small, but which equations can undo each other?
Addition and Subtraction is Inverse Operations
Multiplication and Division is Inverse Operations
