For each new desk that is purchased, by how much does the amount of money left in the school's desk
fund decrease?
O $110
0 $135
$165
$190

is there more to the question?

Step-by-step explanation:

is there anything before that relating to the question or a picture? like “they got ___ desks for ___“ ? i’m not good without context ahaha

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

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
