Area = 1/2 base x height so you would find the area of one of the 3 larger sides which would be 12.2x6.1=74.42 then divide it by 2 which is 37.21. Then multiply it by 3 because of the other sides that are the same which gets you 111.63. Then you find the area of the bottom triangle by doing 5.3x6.1= 32.33 then divide it by 2 which is 16.165. Then you add both numbers together and you get 127.795. Answer is 127.795

MODULAR ARITHMETIC <br><br> If it is 9 o'clock now,what will it be in 111 <br> hours .
zhenek [66]

Answer:

12 o'clock.

Step-by-step explanation:

As we are talking time we work in mod 12.

9 mod12 + 111 mod12

= (9 + 111) mod12

= 120 mod 12

= 0.

So the time will be 12 o'clock.

Problem:thecentral Ohio ski and board club has 150 members. There are 34 more men than women let x represent the number of men a
Komok [63]
The total number of members should be the sum of the number of men, x, and women, y, and that should be equal to 150. In mathematical equation that should be,

                 <em>x + y = 150</em>

If we are to note that there are 34 more men than women in the team, we can say that,
              y = x - 34

The equation then would become,
             x + (x - 34) = 150

The value of x from the equation is equal to 92. With this, the number of the women is equal to 58.
