Write 90 out of 120 as a fraction-90/120. Simplify that until you can't any more and you get 3/4 of the original price.
Y-E = (3/4)(F -E)
Y = (3/4)F -(3/4)E +E
Y = (3F +E)/4
Y = (3(-1) +(-3))/4 = -6/4 = -3/2
the appropriate choice is D. -1.5
Answer:
B . ![f(x+h)=\frac{x+h}{1+x+h}](https://tex.z-dn.net/?f=f%28x%2Bh%29%3D%5Cfrac%7Bx%2Bh%7D%7B1%2Bx%2Bh%7D)
Step-by-step explanation:
Given function is:
![f(x)=\frac{x}{1+x}](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7Bx%7D%7B1%2Bx%7D)
Sall h is used to denote minor change in function. The value of the new function f(x+h) will be calculated by putting x+h in place of x in the function.
So putting x+h in place of x
![f(x+h)= \frac{x+h}{1+(x+h)}\\=\frac{x+h}{1+x+h}](https://tex.z-dn.net/?f=f%28x%2Bh%29%3D%20%5Cfrac%7Bx%2Bh%7D%7B1%2B%28x%2Bh%29%7D%5C%5C%3D%5Cfrac%7Bx%2Bh%7D%7B1%2Bx%2Bh%7D)
So, option B is the correct answer ..
What is the volume of the crushed ice?
volume of the cone = π r² h/3
volume of the small cone = 3.14 * (3in)² * 3in/3
volume of the small cone = 3.14 * 9in² * 1in
volume of the small cone = 28.26 in³
volume of the big cone = 3.14 * (3in)² * 15in/3
volume of the big cone = 3.14 * 9in² * 5in
volume of the big cone = 141.30 in³
volume of the crushed ice = 141.30 in³ - 28.26 in³ = 113.04 in³
