Molly's basic cell phone plan charges $35.99 for service plus $0.21 per minute beyond the included 250 minutes in the plan. How
Ilia_Sergeevich [38]
The answer is $84.29

Let the number of minutes be x.
$35.99 is fixed price and does not depend on the number of minutes x. Each minute costs $0.21 so it depends on x and we have 0.21x in the function. However, 250 minutes are already included and should not be included in x. Therefore, the function that represents the monthly cost looks like this:
f(x) = 35.99 + 0.21 * (x - 250)

Now, let's calculate for x = 480 minutes:
f(480) = 35.99 + 0.21 * (480 - 250)
f(480) = 35.99 + 0.21 * 230
f(480) = 35.99 + 48.30
f(480) = 84.29

Calculate the volume of a cylinder of radius 5cm and height 14cm (take pie 22/7)
HACTEHA [7]

Answer:

<em>Volume of a cylinder = 1,100cm³</em>

Step-by-step explanation:

<em>Volume</em><em> of</em><em> a</em><em> cylinder</em><em> </em><em>=</em><em> </em><em>πr²</em><em>h</em>

<em>Given</em>

<em>π </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>7</em>

<em>r </em><em>=</em><em> </em><em>5</em><em>c</em><em>m</em>

<em>h </em><em>=</em><em> </em><em>1</em><em>4</em><em>c</em><em>m</em>

<em>Substitute</em><em> the</em><em> </em><em>given</em><em> </em><em>information</em><em> </em><em>in</em><em> the</em><em> </em><em>problem</em><em>.</em>

<em>Volume</em><em> of</em><em> a</em><em> cylinder</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>7</em><em> </em><em>×</em><em> </em><em>(</em><em>5</em><em>c</em><em>m</em><em>)</em><em>²</em><em> </em><em>×</em><em> </em><em>1</em><em>4</em><em>c</em><em>m</em>

<em>Volume</em><em> of</em><em> a</em><em> cylinder</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>7</em><em> </em><em>×</em><em> </em><em>2</em><em>5</em><em>c</em><em>m</em><em>²</em><em> </em><em>×</em><em> </em><em>1</em><em>4</em><em>c</em><em>m</em>

<em>Volume</em><em> of</em><em> a</em><em> </em><em>cylinder </em><em>=</em><em> </em><em>1</em><em>,</em><em>100c</em><em>m</em><em>³</em>

which equation in point slope form correctly represents zadas pay in dollars, y, when she works x hours?
Firlakuza [10]

ANSWER

The correct answer is A

y-68=2(x-4)


<u>EXPLANATION</u>

We were told that Zada is paid at an hourly rate of $12 per hour.


The unit rate of payment represents the slope of the straight line graph that models Zada's earnings. Thus m=12


When she works for 4 hours she earns a total of $68 tells us that the point,(4,68) lies on the model straight line.


Using the formula for the point slope form

y-y_1=m(x-x_1)

we obtain the equation as follows.

y-68=2(x-4)
