Answer:
169 sections
Step-by-step explanation:
A couple wants to install hardwood into their bedroom. The wood is bought in 0.5×5 square foot pieces
The area of the 0.5×5 square foot pieces
Area= 0.5*5.
Area= 2.5 square feet
They have 422 square feet of floor on which to install the hardwood.
Number of sections to be purchased
= 422/2.5
= 168.8 sections
Approximately= 169 sections
Answer:
6.50
Step-by-step explanation:
thats what i get
It is given in the question that the formula of volume of cone is
Where V is the volume, r is the radius and h is the height.
And we have to find an expression for h.
First we multiply both sides by 3, and on doing that we will get
Now to isolate h, we have to get rid of pi r square by dividing.
Therefore the correct option is B.
X + y = 9
x - y = 2
x = 5 + y
5 + y + y = 9
5 + 2y = 9
2y = 9 - 5
2y = 4
y = 2
----------
x = 9 - 2
x = 7
