Answer:
$0.90
Step-by-step explanation:

3 dozen = 36

0.4 × y = 36 × 0.1
0.4y = 3.6
0.4y ÷ 0.4 = 3.6 ÷ 0.4
y = 9
mitosis
Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell. divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.
Answer: 8.2 mm
Step-by-step explanation:

Answer: 33.13 in
Step-by-step explanation:
First, let's start with the perimeter of the semicircles.
Since there are two, it is easier to do because the perimeter of the two halves will add to one full circle; so we can just calculate without having to halve anything.
The formula for the perimeter (aka circumference) of a circle is 2πr
Plug the radius into the equation to get 2π4, or 8π
8π ≈ 25.13
The perimeter of the rectangle is 6(4) = 24.
We now have to subtract the diameters of the circles, as they are not on the outside of the figure and won't be counted in the total perimeter. From the 24, we subtract the two diameters, or 16 in.
24 - 16 = 8
The total perimeter then comes out to be 25.13 + 8, or 33.13 in

Determine the scale
The scale is calculated using the following ratio:

Substitute values for Scale and Actual Measurements

Divide ratio by 20.5


This implies that: <em>1 inch on scale represents 8 ft in actual measurement</em>
