Snowcat [4.5K]

Answer:

v/2

Step-by-step explanation:

First, if we expand the expression we know that it is equal to (4/8)*(v^3/v^2)

We can simplify the numbers to get (1/2)*(v^3/v^2)

We know that division of exponents is just subtraction of them, so v³/v² = v^(3-2) = v^1 = v

So, the answer is 1/2 * v or v/2

I hope this helps!

Toski is building a room that is 18 feet long and 14 feet wide. Construct a scale drawing of the shed. Use a scale of inch = 2 f

AURORKA [14]

Answer:

Option A is the answer

Step-by-step explanation:

Toski is building a room having length = 18 feet

Width of the room = 14 feet

Scale has been given as 1 inch = 2 feet

∵ 2 feet = 1 inch

∴ 1 feet = $\frac{1}{2}$ feet

∴ 18 feet length of the room = $\frac{18}{2}=9$ inches

Similarly 14 feet width of the room = $\frac{14}{2}=7$ inch

Now we count the small blocks in the given options.

Option A has 9 blocks or 9 inches as the length of the room and 7 blocks or 7 inches as the width of the room.

Option A is the answer.
