(b) a machine in a food canning factory produces 250 cans every hour. how many cans
would be produced in 25 minutes?
(c) if 14 pens cost $5.60, find the cost of 3 pens.

B ) The number of cans produce in 25 minutes is 104

C) The cost of 3 pens is $1.2

Step-by-step explanation:

Given as :

B) The number of cans produce every hour = 250

Let The number of cans produce in 25 minutes = x

Applying The unitary method

∵ 1 hour = 60 minutes

∵ The number of cans produce in 60 minutes = 250

So, The number of cans produce in 1 minute =

∴ The number of cans produce in 25 minutes = × 25

Or, x = 104.167

Or, x ≈ 104

Hence, The number of cans produce in 25 minutes is 104 . Answer

C) The cost of 14 pens = $5.60

Let The cost of 3 pens = y

Applying unitary method

∵ The cost of 14 pens = $5.60

So, The cost of 1 pen =

∴ The cost of 3 pens =   × 3

i.e y = × 3

Or, y = $1.2

Hence, The cost of 3 pens is $1.2   Answer

b.-4 units

all you   do is count how many times you move

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
