Red area = pi x r^2 = pi (1^2) = pi
Green area = pi r^2 - the red area = 9 pi - pi = 8 pi
Blue area = pi r^2 - green - red areas = 25pi - 8pi - pi = 16 pi
Total area is pi r^2 = 25 pi (16pi + 8pi + pi)
green area is 8 pi
8pi/25pi = 8/25
4 cooks
4 hours
4 cakes
4 cakes / (4 cooks X 4 hours) = 4 cakes / 16 cook-hours = 1 /4 cake/cook-hours
8 cakes / 1/4 cake/cook-hour = 32 cook hours
32 cook-hour / 8 cooks = 4 hours
If 4 (b-c)(c-a) = 0 then either b-c = 0 or c-a = 0
then (b-c)/(c-a) either equals 0 (when b-c = 0) or is 'undefined'
x = number of two wheel bikes
2x = bike tires for two wheelers
47 - x = three wheel bikes
3(47-x) = tires for three wheelers
2x + 3 (47-x) = 112 solve for x (the number of two wheel bikes)
Nice work!
....I have no idea if your answer is correct...There may be multiple answers for a b c d ...BUT question asks for MINUMUM value of a+b+c+d
You're welcome....I hope you understand the answer !
There are two,
here is one x=3 y = -4 h,k is then 3,-4
(x-3)^2 + (y+4)^2 = 25 can you find the other one?
Nice ! I forgot about the other THREE !
a/b = 4 multiply both sides by b
a = 4b divide both sides by a
1 = 4 b/a divide both sides by 4
1/4 = b/a
