Lori bought a 25 pound bag of dog food. Every day, her dogs eat two pounds of food. How many days will the bag last? Between what two whole numbers does your answer lie?

a) Number of days the bag will last = 12.5 days

b) The answer lies between 12 and 13.

Step-by-step explanation:

Step 1 :

Total quantity of the dog food = 25 pounds

Total quantity of food the dog eats per day = 2 pounds

We need to find number of days the bag will last

Step 2 :

The number of days the food will last can be obtained by dividing the total quantity of food by the quantity consumed per day.

Hence

Number of days =  = 12.5 days

The answer lies between 12 and 13.

Step 3:

Answer :

a) Number of days the bag will last = 12.5 days

b) The answer lies between 12 and 13.

answer are

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
