An easier way to do this is to look at the number of sides (9) and subtract it by 2 (7). Then you can just multiply that number by 180
this works for every polygon

Answer:

1260

Step-by-step explanation:

First you will need to find the amount of sides of the polygon:

(After looking it is 9)

Each angle of the side of a nonagon is 140 degrees.

Multiply by 9 since you can make 9 triangles:

140 x 9 = 1260

Mrs. Clark has a glass vase with a base shaped like a hexagon, as shown. The vase is 30 cm tall and the hexagon base has an area
Lisa [10]

Answer: The correct option is fourth, i.e., 1935 cm³.

Explanation:

It is given that the vase is 30 cm tall and the hexagon base has an area of 64.5 cm².

The area of a hexagon base is,

A=\frac{3\sqrt{3}} {2}a^2

Where, a is the side length.

The volume of the a hexagon glass is,

V=\frac{3\sqrt{3}} {2}a^2\times h

V=A\times h

Where, A is area of base of hexagon and h is height of the hexagon glass.

V=64.5\times 30

V=1935

Therefore the volume of the glass is 1935 cm³ and the glass can hold 1935 cm³ water. So, fourth option is correct.

7. Marco is making beaded bracelets. Each
stiks02 [169]

One way to find the least common multiple of two numbers is to first list the prime factors of each number.

8 = 2 x 2 x 2

Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

2: three occurrences

3: one occurrence

So, our LCM should be

2 x 2 x 2 x 3 = 24.

So, Marco can buy, at the very least, 24 beads of each color to have equal colors of beads.
