A jar contain 0.75 L of blackberry juice and 0.60 L of blueberry juice Patrick poured 0.25 L of Java juice into the jar he drank 0.20 of the mixture pour a writing expression to represent the total amount of juice left in the jar part B identify which property is used in each step simplify the expression

1.4 L

Step-by-step explanation:

It is given that a jar contains 0.75 L of blackberry juice and a 0.60 L of blueberry juice. After some time, Patrick tried to poured 0.25 L of Java juice into the mixture. He than drank 0.20 L of the juice mixture.

As the question is asking how many litres of juice is left in the jar, we will add 0.75, 0.60 and 0.25 litres together and then subtract the amount of juice Patrick had drunk, i.e. 0.20

∴( 0.75 + 0.6 + 0.25 )- 0.2

  = 1.4

The associative property is used in each step for the expression. It means that no matter how we group the numbers, the outcome will be he same.

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
