Answer:

Aurora used 4 gigabytes.

Explanation:

Knowing that her total bill for September is $113, we can subtract $65 since that is the phone service. We are left with $48, which is the total amount paid for gigabytes. We can divide that by 4 to get $12, and since each gigabyte is worth $12, it means that Aurora used 4 gigabytes.

Complete the following: a^2 − 16 = (a +______ )(a - _____ )

snow_tiger [21]

Answer:

$a^{2} -16$ = (a + <u>4</u>) (a - <u>4</u>)

Step-by-step explanation:

The given equation is $a^{2} -16$

Now, By ALGEBRAIC IDENTITY:

$a^{2} -b^{2} =(a - b) (a + b)$

Here, taking $b^{2} = 16$ , we get b = 4

as $4^{2} = 16$

So, the right hand side of $a^{2} -16$ is (a + 4) (a-4)

Beach Bicycles sells two-seater bicycles. Its markup rate is 68%. Which equation represents the new price for a bicycle, y, give

lesantik [10]

Answer:

y = 1.68x

Step-by-step explanation:

The markup rate of a product or service refers to how higher the selling price is than the total production cost. In this case, this company doesn't produce the bikes, instead it purchases them from a wholesaler, distributor or even the factory, and then resells them in order to make a profit.

E.g. Beach Bicycles purchases two-seater bikes at $200 each, and then it will resell them to their customers at 1.68 x $200 = $336. The total markup in this example is $136, which represents $136/$200 = 68% of the purchase price.
