It would take 20 hours since 8,000 times 5 is 40,000 so 4 times 5 is 20.
Logic.
Answer: 4 pancakes
Step-by-step explanation: because 30min÷6pancakes=5
So, 20min÷5=4
For this case we can make the following rule of three:
1/4 --------> 1/8
1 ----------> x
From here, we clear the value of x.
We have then:
x = (1 / (1/4)) * (1/8)
Rewriting:
x = 4 * (1/8)
x = 4/8
x = 1/2 minutes
Answer:
it takes her 1/2 minutes to write a full page
Let's take a look at D:
<span>D) y = (x-1)^2 - 16 Compare this to
y = (x-h)^2 + k This is the std. equation of a parabola in vertex form.
You can see, by comparison, that h=1 and k= -16; these are the coordinates of the vertex, clearly shown in the diagram.
Since the coefficient of (x-h)^2 is +1, the graph opens upward (which the given graph confirms), and is neither compressed nor stretched vertically.</span>
