Nathaniel purchases a one-year membership pass to an art museum. As a member, he receives a discounted entrance fee. The total c
wolverine [178]

It's a linear function with y-intercept = 12.

The slope-intercept form:

f(x)=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

Let's read the coordinates of two points on the graph:

(2, 15) and (4, 18)

Substitute to the formula of a slope:

m=\dfrac{18-15}{4-2}=\dfrac{3}{2}=1.5

We have the equation of a line:

\boxed{f(x)=1.5x+12}

We need calculate the value of function for x = 1 and x = 20.

Substitute:

f(1)=1.5(1)+12=13.5

f(20)=1.5(20)+12=30+12=42

$12 is the "Fixed Fee", therefore the discounted entrance fee to the art museum is

\$13.50-\$12.00=\$1.50

The total cost is $42.00 after 20 visits.

(a) Which department accounts for approximately one-fifth of the annual budget? Select One (b) Approximately what percentage of
Goshia [24]

a. The department that accounts for approximately one-fifth of the annual budget, based on the pie chart, is the <u>Research Department</u>.

b. The percentage of the annual budget used by the Marketing and Sales departments combined is 30%.

c. If 18% of the annual budget is used for Research, approximately the percentage used for Marketing is 9%.

<h3>What is a pie chart?</h3>

A pie chart is a graphical representation of data in a circle.  In this pie chart, the area or percentage of the whole circle is 100%

Thus, we can obtain the values of the different groups represented in the pie chart by systematically dividing the circle accordingly.

The rule to follow is that vertical angles are always congruent (equal) as they have two lines that intersect to form opposite angles.

<h3>Data and Calculations:</h3>

Research, Sales, and Marketing = 50% of the budget (half of the pie chart)

Research = 18%

Sales and Marketing = 32% (50% - 18%)

Research equals Media and Support and Media and Support are equal.

Therefore, Media is 9% (18%/2) and Support is also 9%.

Since opposite angles are always equal, Engineering (opposite to Sales and Marketing combined) is 32%.

This results in a total of 100% (18% + 32% + 9% + 9% +32%)

<h3>Question Completion:</h3>

The pie chart attached shows how the annual budget for Equipment Producers Incorporated is divided by department. Use this chart to answer the questions below.

c) If 18% of the annual budget is used for Research, approximately what percentage is used for Marketing?

Thus, the department that accounts for approximately one-fifth of the annual budget, based on the pie chart, is the <u>Research Department</u>.

The scale of a map is 1cm:12 km. find the actual distance for 12cm
anzhelika [568]
This is simply a question about ratios. This ratio means that for every 1 cm on the map, there are 12 km in actuality. You can set this problem up in fractions:

1 cm           12 cm
--------   =   ----------
12 km             x

To solve for x, we cross-multiply, for the moment ignoring units. Remember, your answer will be in km.

1*x=12*12

x=144

If x=144, then for 12 cm, there are 144 km.
