an online pet store ships to cases of dog food and four bags of treats the dog food weighs 13 1/2 ounces per can and there are 12 cans in a case the dog treats are shown write and evaluate an expression to show the total weight of the items​

162

Step-by-step explanation:

13 and a half in decimal form is 13.5

you multipy 13.5 and 12 which gives you 162

(don't let the decimal confuse you just take it out and multipy like so then add it back again)

Hope this helps ;)

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.
