Answer: y = -1
Step-by-step:
-8y + 1 = -9y
Subtract 1 from both sides
-8y = -9y-1
Add 9y to both sides to isolate y
y = -1
We are given an equation d = 5h, where d is the depth of snow and h is the number of hours of a snowstorm.
We need to find the number of hours of a snowstorm that accumulate the snow to 1 centimeter.
In order to find the number of hours that accumulate the snow to 1 centimeter, we need to plug d=1 in the given equation.
On plugging d=1, we get
1= 5h.
Dividing both sides by 5, we get
1/5 = h.
<h3>Therefore, it would take 1/5 hour for 1 centimeter of snow to accumulate in Harper's yard</h3>
Answer: a = 8
Step-by-step explanation:
Volume of a square based pyramid is given as
.
where a is the length of the side and h is the height.
Substituting into the formula , we have
V = 
128 =
/3
384=
X 6
Divide through by 6
384/6 = 
64 = 
Therefore :
a = 
a = 8
