19 chairs.
650-176 is 474 and 474 divided by 25 is 18.96 so round up and 19 or 18 per row
First one is -3
Second one is 1
Answer:
3.14×5(2)×6=471.24
Step-by-step explanation:
you have to take square of 5
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y + 6)² = 16 is in this form
with r² = 16 ⇒ r =
= 4
---------------------------------------------------------------
given (h, k) = (5, 2) and r = 20, then
(x - 5)² + (y - 2)² = 400 ← represents the delivery area
Answer: {x,y} = {2,-4}
[1] x - y = 6
[2] 2x + y = 0
