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 - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form
centre = (6, - 1) and r =
= 2
Answer:
r= 
Step-by-step explanation:
The sum to infinity of a geometric series is calculated as
S∞ =
; | r | < 1
where a₁ is the first term and r the common ratio
here a₁ = 15 and S∞ = 45 , then
45 =
( multiply both sides by (1 - r ) )
45(1 - r) = 15 ( divide both sides by 45 )
1 - r =
=
( subtract 1 from both sides )
- r =
- 1 = -
( multiply both sides by - 1 )
r = 
Lets say the final price of the bike is SP plus 13% VAT. So:
1.13 * SP = 6356.25
SP = 5625
Now SP was after 10% discount on Original Price, say MP. So:
0.9 * MP = 5625
MP = 6250
Therefore, the percent of Marked Price above Cost Price is:
(6250 - 5000) * 100/5000 = 25%
Answer:
40 by 2.5 ?
Step-by-step explanation:
Make them both over 54:
so 7/9= 42/54
and 5/6= 35/54
now you can easily see that 7/9 is larger than 5/6
