Answer:

D) Their slopes are equal.

Step-by-step explanation:

For a line to be parallel, both lines need to be going at the same angle forever and never intersect. So if the slopes of the lines are equal, both of the lines would be at the same angle going the same direction. It does not matter where the lines are on the graph! It can be on top of the other line or far away from the other line, it just needs to have the same slope.

Total Price: The sales tax rate is 5%. If the sales tax on a 10-speed bicycle is $9, what is the purchase price?

Lesechka [4]

Answer:

The purchase price is $180

The total price is: $189

Step-by-step explanation:

Sales tax rate = 5\%

Sales tax on bike = $9

We need to find the purchase price.

Let purchase price = x

We know that Sales tax = 5% of x

and Total price = Purchase Price + Sales tax

So, we can write:

Sales tax = 5% of x

Putting values and finding x

$9 =5\% \:of\: x\\9=\frac{5}{100}\:of\:x \\x= \frac{9*100}{5}\\x=180$

So, the value of x i.e Purchase price = $180

The purchase price is $180

Now finding the total price of bicycle

Total price = Purchase Price + Sales tax

Total price = 180 + 9

Total price = $189

So, The total price is: $189

the populatipn of a school of fish increases at a rate of 18% a Month. There are currently 500 fish in the school.

ruslelena [56]

You first must find the 18% of the fish population.

You multiply 500 by .18 . You are supposed to get 90.

90 is the 18% fish increase.

Then you just add 500 + 90 and you will get 590 fish that are now in the school.
