Machine A can produce 435 widget in 3 hours. At this rate how many widget can machine A produce in 7 hours?

Vesna [10]

Answer:

1015 widgets

Step-by-step explanation:

First investigate how many widgets can machine A produce in 1 hour:

If it produces 435 in 3 hours, then it will produce one third of that in one hour:

In ONE (1) hour $\frac{435}{3} = 145$ widgets

Therefore in seven (7) hours it will produce seven times the amount it does in one hour, that is:

$145 * 7 = 1015$ widgets

Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.

<h3>Slope of a function</h3>

Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.

The formula for expressing the slope of a function is given as;

f'(x) = f(b)-f(a)/b-a

a and b are the intervals

The slope can also be expressed as a function of its coordinate (x, y)

Slope = y2-y1/x2-x1

Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the numb

Karo-lina-s [1.5K]

Answer:

Yes

Step-by-step explanation:

The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).

The number of hours worked is $x$ and the money earned is $y$ .

Let us divide the values of $y$ by $x$

$\dfrac{72}{6}=12$

$\dfrac{96}{8}=12$

$\dfrac{66}{5.5}=12$

$\dfrac{108}{9}=12$

$\dfrac{84}{7}=12$

The fuction which defines the above ordered pairs is $y=12x$

It can be seen that the amount of money earned is 12 times the number of hours worked.

So, per hour Jerry earns 12 dollars.

Hence, the ordered pairs are relation.

Kevin works for a company which produces printers. A printer sells for $163.95 and costs $48.28 to produce. In one month, Kevin’

victus00 [196]

Answer:

Option D $26,792

Step-by-step explanation:

When producing 427 printers, the cost of production is 427*$48.28=$20,615.56

When selling each printer, profit per printer is $163.95 - $48.28= $115.67

Total money after selling the 427 printers is 427*$163.95 =$70006.65

Subtracting cost of production from value of sales we deduce

$70006.65-$20,615.56=$49391.09

Non-profit overhead expenses will be the difference between the expected profit and the actual profit earned

$49391.09 -$22,599.09.=$26,792

Therefore, option D, $26,792 is the right choice
