Answer:28 dollar
Step-by-step explanation: 140 x (20/100)= 28 dollar
140-28= 112 the price after the sale
B = x^2−x / 3g

Answer:
216= 7/8 x L -8
Step-by-step explanation:
Given that,
One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder
The first cylinder’s volume is 216 centimeter cubed
From given,
Let "x" be the volume of second cylinder
Therefore,
Volume of first cylinder = 7/8 of the volume of a second cylinder - 8
Thus the volume of second cylinder is 256 centimeter cubed
Answer:
There are vertical asymptotes at x: {-1, 0, 5}
Step-by-step explanation:
It's easier (at least for some) if you write this function as
3
F(X) = ------------------
x(x-5)(x+1)
Can you now see that if x = 0, this function is undefined? Same for x = 5 and x = -1? There are vertical asymptotes at x: {-1, 0, 5}
Let the amount deposited (principal) be x, then the amount after the required time = 2x.
A = P(1 + r/n)^nt: where A is the future value = 2x, P is the principal = x, r is the rate = 0.75%, n is the number of accumulation in a year = 12, t is the number of years.
2x = x(1 + 0.0075/12)^12t
2 = (1 + 0.000625)^12t
log 2 = 12t log (1.000625)
log 2 / log (1.000625) = 12t
1109.38 = 12t
t = 92 years
