Jerry walked a dog from 6: 40 am to 7: 30am . if he was paid $6 per hour how much did he earn

Amount Jerry earned is $5

Step-by-step explanation:

Jerry is paid $6 per hour.

First we need to find the number of hours he walked the dog.

From 6.40 am to 7.30 am we have 50 minutes. Jerry walked the dog for 50 minutes.

An hour has 60 minutes.

We need to find how much Jerry gets paid for a minute.

Amount paid for a minute     =

                                               =$

Therefore,

Amount paid for 50 minutes = $ * minutes

                                                =$

answer: 0.95, d

step-by-step explanation:

first, you have to combine the percentages of costumers ordering pizza or salad. 25% (percent of salads ordered) plus 70% (percent of pizzas ordered) is equal to 95%. then, turn 95% into a fraction: 95/100. lastly, divide 95 by 100 and you will get 0.95, d.

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
