So if one bit of the length, is half the size of the other bit then we can make the following equation, for x being the length of rope:
x + 2x = 66
3x = 66
x = 22
That is the length, of the smaller one (half the big one), so 2x = 44. Hence d) is your answer.
Hope I helped!
Answer:
see below
Step-by-step explanation:
x = 63 and y = 27
180 - 117 Gives 63
Answer:
8.9 grams per centimeters cubed
Step-by-step explanation:
The formula for density is D=M÷V
Just divide 222.50 by 25.00 and you are done.
The quadratic formula is
.
From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:
![x=\frac{-(-1(-1)\pm\sqrt{(-1)^2-4(1)(12)} }{2(1)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-%28-1%28-1%29%5Cpm%5Csqrt%7B%28-1%29%5E2-4%281%29%2812%29%7D%20%7D%7B2%281%29%7D)
Because there is a square root of a negative number, there is no solution.
