There was a fair at Brad's high school this weekend. It was open for 10 hours on Saturday and the ticket sales were recorded. Th
Masteriza [31]

Answer:

The rate of change is 4.6 tickets/hour.

Step-by-step explanation:

The equation that represents the ticket sales is the equation of a line:

y = 4.6*x - 12.2

The equation of any given line can be writen by the following formula:

y = m*x + b

Where "m" is the slope of the line, or the rate of change, while b is the value for "y" when "x" is zero. Therefore in this case the rate of change is the number multiplying "x", so 4.6 tickets/hour.

Suppose that work hours in new zombie are 200 in year 1 and productivity is $8 per hour worked. what is new zombie's real gdp? i
olasank [31]
Given that <span>work hours in new zombie are 200 in year 1 and productivity is $8 per hour worked.

The new zombie's real gdp in year 1 is given by 200 x $8 = $1,600

If work hours increase to 210 in year 2 and productivity rises to $10 per hour.

The new zombie's real gdp in year 2 is given by 210 x $10 = $2,100

The new zombie's rate of economic growth is given by

\frac{\$2,100-\$1,600}{\$1,600} \times 100\%= \frac{\$500}{\$1,600} \times100\%=31.25\%</span>

A regular polygon has a perimeter of 40 cm and a apothem of 6 cm. find the polygons area
Anestetic [448]

Answer:

a = 120 cm²

Step-by-step explanation:

n = number of sides

edge length

40/n

divide the polygon into n congruent triangles

a = (1/2)(edge * apothem) * number of triangles

a = (1/2)(40/n)(6) * n

n cancels out

a = (1/2)(40)(6)

a = 120 cm²

The time required to complete a job varies inversely as the number of people working. it took 4 hours for 7 electricians to wire
Solnce55 [7]
Let's assign variables

The time required to <span>wire a building: y
</span>
The number of electricians <span>to have done this job: x

</span>
<span>y varies inversely as x

so that:
y= k\frac{1}{x}
where  k is the proportional constant


To calculate the value of k, plug in the values of x and y:
x=7
y=4

4=k (\frac{1}{7}) \\~\\k=28


Now, write down the relation between x and y:
y=28x


"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
y=(28) \frac{1}{3} = \frac{28}{3} =9 \frac{1}{3} =9.333333~~hr

So it would take 9 hours and 20 minutes to have this job done.
