Answer:

13.3

Step-by-step explanation:

shaded area = area of rectangle - area of semicircle.

5 inch = 12.7cm

6 inch = 15.24 cm

diameter = 12.7

radius = 12.7/2

= 6.35 cm

hence shaded area = (12.7 x 15.24) - (3.14 x 6.35 x 6.35 / 2)

= 193.548 - 63.306325

= 130.241675

= 130.24 (approx.)

Answer:

Step-by-step explanation:

The formula gives you a relation between S and n. For every n, you can perform the calculation and obtain an S.

So, for n=0 we get 0/2 (0+1) which equals 0. So (0,0) is an (n,S) pair.

The given polygons are similar

Step-by-step explanation:

By observing the given diagrams, we can see that the respective angles are congruent.

Two shapes are said to be similar if they have same shapes or one shape is created by uniformly increasing or decreasing the side of other.

For this purpose we find the scale factor of greater to smaller image, if the scale factor is same for each side then the two shapes are similar

So,

The scale factor is:

$\frac{EF}{AB} = \frac{3}{1} = 3\\\\\frac{FG}{BC} = \frac{9}{3} = 3\\\\\frac{GH}{CD} = \frac{15}{5} = 3\\\\\frac{EH}{AD} = \frac{21}{7} = 3$

We can see that the scale factor is same for all sides.

Hence,

The given polygons are similar

It's gonna be 5 - (2 + 4 -2)
according to order of operations, we have to solve inside the parentheses/brackets first (from left to right)

therefore, it will be
5 - (6 - 2)
=5 - (4)

Next, distribute the negative to the four and add normally.

= 5 - 4
= 1
