(7/8) of an hour is 52.5 minutes.
If you are looking for half of that, it would be 26.25 minutes or 26 minutes and 15 seconds.
Answer:
b=36-d
Step-by-step explanation:
b=balloons after being popped
d=balloons popped
Answer:2.5 cups
Step-by-step explanation:
Given
Rosanne runs 6 miles in an hour
If she drinks 0.5 cups of water every 
of an hour
So in 1 hour Rosanne drinks 1.5 cups
So, for 6 miles Rosanne drinks 1.5 cups
i.e. For 
for 
From the function y=x^2-4x+7
to complete the square we proceed as follows:
The vertex form is given by:
y=(x-h)^2+k
where (h,k) is the vertex:
thus from the function we shall have:
y=x^2-4x+7
c=(b/2a)²
c=(4/2)²=4
thus adding an subtracting 4 in the expression:
y=x^2-4x+4-4+7
y=(x-2)^2+3
thus the vertex will be:
(2,3)
The answer is:
<span>D. Minimum at (2, 3)</span>
