With a full ink cartridge, the printer can print 2,500 pages. The printer cartridge is now 37% full. Which is the best estimate

stira [4]

Answer: 925 pages

Step-by-step explanation:

From the question, we are told that with a full ink cartridge, a printer can print 2,500 pages but that the printer cartridge is now 37% full.

The best estimate of the number of pages the printer can still print will be calculated as:

= 37% × 2500

= 0.37 × 2500

= 925 pages

Compute the sales tax on the following transactions. An article retails for $37.50. The city sales tax is 6%, and the federal ex

ratelena [41]

First you must find the rate of both taxes. Since its 8% and 6%, you must add them both together, then divide them by 100.

14/100 = .14

Then for both rates you must add 1 because it is a tax increase.

1 + .14 = 1.14

Finally times 37.50 with 1.14

37.50(1.14) = <span>42.75

<span>$42.75 is the answer.</span>

The production cost, represented by y, of smart phone devices are equal to the product of computing components (a) and the squar

Marta_Voda [28]

The production cost is an illustration of a quadratic function

<h3>How to determine the equation</h3>

We have the following parameters:

Computing components (a)
Number of devices (x),
Labor (b)
Savings on reusable material (c)

Using the instructions in the question, the equation of the production cost would be:

$y =ax^2 + bx -c$

Hence, the production cost is $y =ax^2 + bx -c$

<h3>Change the subject of the equation</h3>

In (a), we have:

$y =ax^2 + bx -c$

Subtract bx - c from both sides

$y - bx + c = ax^2$

Divide through by x^2

$a = \frac{y - bx + c}{x^2}$

Hence, the equation that represents the computing component is $a = \frac{y - bx + c}{x^2}$
