Atable and 8 chairs weigh 235.68lb together if the table weighs 157.84 lb, what is the weight of one chair in pounds

9.73 lb

Step-by-step explanation:

The total together is 235.68 lb.  Taking away the weight of the table, 157.84, we are left with

235.68-157.84 = 77.84 for the weight of all of the chairs.  Dividing this by 8 gives us the weight of one chair:

77.84/8 = 9.73

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
