The formula for the area of a circle is PI x radius^2.

To find the area of the sector, you would multiply the area by the ratio of the the sector angle over 360.
 The formula would become PI x r^2 x 30/360.
 The 2nd choice is correct.

What is the selling price of an item if the original cost is $784.50 and the markup on the item is 6.5 percent?
kotegsom [21]

Answer:

835.49

Step-by-step explanation:

selling price = original cost + markup value

We need to find the markup

markup = original cost * markup percent

             = $784.50 * 6.5%

           = $784.50 *.06.5

           =50.9925

Rounding to the nearest cent

            =50.99

selling price = original cost + markup value

                     =784.50+50.99

                      835.49

1. Which situation does NOT represent a functional relationship?
Alex

Answer:

  • 1. D
  • 2. C

Step-by-step explanation:

1. .....................................................................................................

A. This is a functional relationship as the number of workers depend on the number of job sites.

  • y = 5x

B. This is a functional relationship as the amount of money is dependent on the number of withdrawals

  • y = 2500 - 200x

C. This is a functional relationship as the number of vitamins depend on the number of monkeys

  • y = 3x

D. This is NOT a functional relationship as the output is a fixed value. The performance and scoring may repeat.

2. .....................................................................................................

<h3>Given</h3>
  • A = 62x -100
  • B = 2x - 3
<h3>To find </h3>
  • A/B
<h3>Solution</h3>
  • A/B =
  • (62x - 100)/(2x - 3) =
  • (31*2x - 31*3 - 7)/(2x - 3) =
  • (31(2x - 3) -7)/(2x - 3) =
  • 31 - 7/(2x - 3)

Correct option is C.

Karolina [17]

Answer:

a) The ratio of passenger cars to pickup trucks is \frac{5}{7}

The ratio of pickup trucks to passenger cars is \frac{7}{5}

The ratio of passenger cars to total vehicles is \frac{5}{12}

The ratio of pickup trucks to total vehicles is \frac{7}{12}

b) The tape diagram is shown in the attached picture.

c) The tape diagram has 12 equal-sized parts.

d) The total quantity that the tape diagram represent is 192.

e) The value of each individual part of the tape is 16.

f) There were registered 80 passenger cars and 112 pickup trucks.

Step-by-step explanation:

a) According to the information in the problem, that for every 5 passenger cars registered, there were 7 pickup trucks registered.

So the ratios are:

Passenger cars to pickup trucks: \frac{5}{7}

Pickup trucks to passenger cars: \frac{7}{5}

If we calculate the total vehicles: 5+7=12

So, we can get two ratios more:

Passenger cars to total vehicles is \frac{5}{12}

Pickup trucks to total vehicles is \frac{7}{12}

b) We make a tape diagram where each box represents a vehicle so we draw 5 boxes for cars and 7 boxes for pickup trucks.

c) If we count the total quantity of boxes, there are 12.

d) This diagram represents the total quantity of registrations in August which is 192.

e) To get the representation of each part of the tape diagram we have to divide 192 by 12. 192÷12=16

f) Finally, we multiply 16 by the number of boxes of each type of vehicle:

Cars: 16×5=80

Pickup trucks: 16×7=112
