a truck holds at most 20.000 lb. there are 18 boxes on the truck. eaxh weighs 750 lb. how many additional boxes can the truck hold? graph the solution show your work

6

Step-by-step explanation:

750 x 18 = 13,500lb

Remaining weight until truck is full = 20,000 - 13,500 = 6,500

6,500 ÷ 750 = 8.66666666667

You cannot have 8.666... of a box and therefore, the answer = 6

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
