Answer:

The answer would be A.) 111

If the sales tax in your city is 11.4%, and an item costs $160 before tax, how much tax would you pay on that item? Round to the
Oksana_A [137]
First we calculate the tax on the item:
11.4%($160) = 11.4(160)/100 = 18.24
hence the tax for the item is $18.24
The total price for the item would be:
160 + 18.24 = 178.24
hence the total price for the item including tax is:

The Rogers family drove a total of 482 miles, starting on
Trava [24]

you add up 138+225 and you get 363 then you subtract 482-363 this is how you set it up:

   4  8  2

- 3  6  3

------------

you have to borrow because 3 does not go into 2 so you change the 8 into a 7 then you 10 to 2 and you get 12 so this is what it looks like:


     4   7   12

-    3   6   3

-------------------

 so you then subtract 12-3=9 then 7-6=1 then 4-3=1

so this is what it looks like

    4     7    12

--- 3    6     3

--------------------

    1     1     9

so on Sunday they rode 119 miles

Alchen [17]

g(-3)=\frac{-3+1}{-3-2}=\frac{2}{5} \\ \\ h(-3)=4-(-3)=7 \\ \\ (g\times h)(-3)=7\left(\frac{2}{5} \right)=\boxed{\frac{14}{5}}

A parking lot has seventy-eight parking spaces numbered from 1 to 78. There are no cars in the parking lot when Jillian pulls in
polet [3.4K]

Answer:

49/78

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that the number on the parking space where she parks is greater than or equal to 30 = numbers greater than or equal to 30 / total numbers

49 / 78
