Answer: y=54
Step-by-step explanation: since a triangles angles =180 and you just have this equation 180-72=2y that equals 108=2y
First, let's review the formula for the "sum of two cubes:"
a^3 + b^3 = (a + b)(a^2 - ab + b^2).
Unfortunately, 9 is not a perfect cube. The cube root of 9 is 9^(1/3), and the square of the cube root of 9 is therefore 9^(2/3).
Thus,
9x^3 + 64 = (9^(1/3)*x + 4) * (9^(2/3)x^2 - 4*9^(1/3) + 16)
Answer:
I'm in class so I'll answer what I can!
1. okay so 25%=40 so to get to 100% we need to multiply 25% by 4 and so we so the same with the number 40x4 equals 160cm
2. so 8k from 20k think of 10k as 50% so it's around 5 per 1k so 8k would be 40% and so 60% would have been spent
3. (I might edit this one later I'm in class :(()
4. so 200cm last year and 240cm this year so it gre by 40cm so it'd be 20% (200=100% so that means it's twice as much as what the % would be!)
5. so 60 is 40% so 30 is 20% so just add up from there 20 x 5 = 100% so 30 x 5 = 150km
Answer:
Anna has $36.39 dollars.
Step-by-step explanation:
All we have to do is subtract
54 - (26.34 + 1.27) =
54 - 27.61 =
36.39
So, the answer is 36.39
Hope this helps! :)
