Answer:

8. 16,648

9. 1,394

10. 3

11. 9,570

Step-by-step explanation:

8. Total means all together so you need to add all of the attendants together.

2118 + 3391 + 4785 + 6354 = 16,648

9. How many more signifies the need to use subtraction to get your answer so you need to subtract the number of attendants in 2011(3,391) from the number of attendants in 2012(4,785)

4,785 - 3,391 = 1,394

10. How many times more signifies the need to use division in order to get the answer since it is the opposite of multiplication. So, you need to divide the number of attendants in 2010(2,118) from the number of attendants in 2013(6,354)

6,354 / 2,118 = 3

11. Twice the attendance signifies the need to use multiplication to find your answer so you need to multiply the number of attendants in 2012(4,785) twice(2).

4,785 x 2 = 9,570

Hope this helped! <3

Find the area of the rhombus . Each indicated distance is half the length of its respective diagonal.
lukranit [14]

Given:

The length of diagonals of a rhombus are 12 ft and 5 ft.

To find:

The area of the rhombus

Solution:

Area of a rhombus is:

Area=\dfrac{d_1d_2}{2}

Where, d_1,d_2 are two diagonals of the rhombus.

It is given that the length of diagonals of the rhombus are 12 ft and 5 ft.

Putting d_1=12,d_2=5, we get

Area=\dfrac{12\times 5}{2}

Area=\dfrac{60}{2}

Area=30

Therefore, the area of the rhombus is 30 square ft.
