I am going off the assumption that by "She used a cup of sugar" you mean that she used 1 cup of sugar. Since the model shows that her first step starts with 1.5, that means that she loses 1 cup, and moves 1 unit to the left. She is left with 0.5 cups of sugar.
B. She only moves 1 unit to the left.
It is quadratic equation.
First we have find delta given by formula: delta=

where our
a=16
b=-24
c=7
so, delta=

Because delta is positive, there is real results.
Now we can use next formula x=

, to find roots (results, 2 results because its quadratic equation and delta is greater than 0)
x1=

x2=
Answer:
175 cm³
Step-by-step explanation:
the volume( V) of a rectangular prism is
V = area of base × height = 5² × 7 = 25 × 7 = 175 cm³
P(A) =0.54
P(B)= 0.68
P'(A)= 1-0.54 = 0.46
P'(B)= 1- 0.68 = 0.32
The probability of neither of both event will occur:
= P'(A)×P'(B)
=0.46 × 0.32
=0.1472
