if 5x=100, x=20. If we plug this in the equation we get 5(20+2)= 5(22)= 110
I tried 24 but thats not it
arc LPM on the larger circle = 360 - 72 = 288°
arc LOM on the smaller circle = 360 - 2 (72) = 360 - 144 = 216°
so we have 17-3+9-3=14+6=20 so 30 people own a cat or a dog
Alternate way:
there is 17+9-3=23 people we then do 23-3=20 people who own a cat or a dog
The discriminant of the quadratic formula must = 0 to have only one root
b^2 - 4ac = 0
b in the quadratic formula for this case is -2b+2 a is 2b-5 c is 3
Plug these values into the red equation to find b = 4
Don's apples = D Alan's apples = A D = A * 1.666
A - 30 = (D -30)/5 A = 54 D = 90 Alan had 54 apples at first
can you explain why
maybe explain if possible since i'm still confused on how you got to the answer
can you explain if possible?
This is the question I need help with idk why it wasn't showing up before
4 < sqrt(n) < 10
Is something wrong with web calc? when I type in things and post it, it doesn't show up
Must have been A glitch or something since it says for me "Find the number of positive integers n so that 4
Hope this helps, feel free to tell me if i'm wrong :)
2 log (a - 2b ) = loga + log b
log (a - 2b)^2 = log (a*b)
This implies that
(a - 2b)^2 = ab
a^2 - 4ab + 4b^2 = ab
a^2 - 5ab + 4b^2 = 0
(a - 4b) (a - b) = 0
a = 4b ⇒ a/b = 4 or
a - b = 0 ⇒ a = b ⇒ a/b = 1
