A cappella grandmas in Magalloway 7N and I’m gonna set alarm when I get
Y/x=6 is the equation hope this helped.
Answer:
it would be 20%
Step-by-step explanation:
out of 100% you would subtract the 23%, 30%, 15% and, 12% and you would get 20%
By proportion ( let x = height of the tree):-
1.38 / 1.87 = 3.03 / x
x = 3.03 * 1.87 / 1.38 = 4.11
Height of the tree is 4.11 meters to nearest hundredth.
Answer: 0.68 or 13.92
Step-by-step explanation:
If the height is 47 meters, then the height, h, is equal to 47.
![47=73t-5t^2\\\\5t^2 - 73t+47=0](https://tex.z-dn.net/?f=47%3D73t-5t%5E2%5C%5C%5C%5C5t%5E2%20-%2073t%2B47%3D0)
Using the quadratic formula,
![t=\frac{-(-73) \pm \sqrt{(-73)^{2}-4(5)(47)}}{2(5)}\\\\\\t=\frac{73 \pm \sqrt{4389}}{10}\\\\\\ t=\frac{73+\sqrt{4389}}{10}, \frac{73-\sqrt{4389}}{10}\\\\\boxed{t \approx 0.68, 13.92}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B-%28-73%29%20%5Cpm%20%5Csqrt%7B%28-73%29%5E%7B2%7D-4%285%29%2847%29%7D%7D%7B2%285%29%7D%5C%5C%5C%5C%5C%5Ct%3D%5Cfrac%7B73%20%5Cpm%20%5Csqrt%7B4389%7D%7D%7B10%7D%5C%5C%5C%5C%5C%5C%20t%3D%5Cfrac%7B73%2B%5Csqrt%7B4389%7D%7D%7B10%7D%2C%20%5Cfrac%7B73-%5Csqrt%7B4389%7D%7D%7B10%7D%5C%5C%5C%5C%5Cboxed%7Bt%20%5Capprox%200.68%2C%2013.92%7D)
