Step-by-step explanation:

number of cups of chocolate syrup= 11 1/4 cups

For ever sundae, he decides to make, it will require 3/4 cup of chocolate

Number of sundae , Danny can make = number of cups of chocolate syrup /3/4 cup of sundae

Solve for t. d=−16t2+4t t=12±41−4d‾‾‾‾‾‾√ t=8±1−4d‾‾‾‾‾‾√ t=18±1−4d√8 t=12±41−4d√2

Answer:

$t=\dfrac{1}{8}\left(1\pm\sqrt{1-4d}\right)$

Step-by-step explanation:

Rearranging your quadratic to standard form, you get ...

16t^2 -4t +d = 0

For the quadratic formula, you have ...

a = 16

b = -4

c = d

so the solution is ...

$t=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(16)(d)}}{2(16)}=\dfrac{4\pm 4\sqrt{1-4d}}{32}\\\\t=\dfrac{1}{8}\left(1\pm\sqrt{1-4d}\right)$
