You can proceed like this,

650 kb for a pic
and 2200kb for song ( 650 + 1550)

total= 18150 kb and 16 files

so, 650 kb each in both pic and song = 16 * 650= 10400

remaining = 18150-10400 = 7750 , which is contributed by additional 1550 of songs that is
7750/1550 = 5

so, a total of 5 songs and 11 pictures were sold..

hope it helped

A cell phone cost $210 a battery charger costs $15 and batteries cost $5 .what is the sales tax and total price for purchasing t

Savatey [412]

The total price with sales tax is $ 246.1

<h3><u>Solution:</u></h3>

Cost of cellphone = $ 210

Cost of battery charger = $ 15

Cost of batteries = $ 5

So total cost can be calculated by adding cost of cellphone and Cost of battery charger and Cost of batteries

Total cost = 210 + 15 + 5 = $ 230

Given that sales tax is 7%

sales tax = 7% of total cost

sales tax = 7 % of 230

$\text {sales tax }=\frac{7}{100} \times 230=16.1$

Total cost including sales tax = 230 + 16.1 = $ 246.1

Thus the total price with sales tax is $ 246.1

Is the graph of the linear inequality y > -x - 3?

klasskru [66]

Answer:

Second Graph

Step-by-step explanation:

Given the linear inequality, y > -x - 3, an easier way of determining its graph is through a test point.

A test point is an ordered pair that is not on the actual line of the graph. The point of origin, (0, 0) is often used for this purpose.

Substitute the values of (0, 0) into the linear inequality to find out whether it satisfies the given inequality statement:

y > -x - 3

0 > - (0) - 3

0 > - 0 - 3

0 > -3 (True statement). Therefore, the shaded region must contain the test point since it is one of the solutions to the given linear inequality.

Hence, the correct answer is the second graph.
