natta225 [31]

Answer:

Option d is correct.

The number of students that chose Target as their favorite store over Ross = 4 students.

Step-by-step explanation:

The graph of the question is obtained from another brainly question on here. But uploading it will lead to deletion of this answer as it would be violating the community guidelines here.

So, I'm going to describe the graph.

The graph provided with the question is a pie chart, with each region clearly shown and the corresponding percentage for each of the students' favourite stores that come up in the survey given as

TJMax - 20%

Wal-Mart - 25%

Ross - 20%

Target - 25%

Others - 10%.

How many more students surveyed chose Target as their favorite store over Ross?

Total number of students sampled = 80

Number of students that picked Target

= 25% × 80 = 20 students

Number of students that picked Ross

= 20% × 80 = 16 students.

Number of students that chose Target as their favorite store over Ross = 20 - 16 = 4 students.

Hope this Helps!!!

6 is added a number x.then the result is multiplied by 9. the final answer is greater than 99
drek231 [11]

So this inequality is going to be written as 9(x + 6) > 99


Firstly, you want to foil 9(x + 6), which will look like this: 9x + 54 > 99


Next, subtract 54 on both sides of the equation: 9x > 45


Lastly, divide both sides by 9, and your answer will be x > 5

A small pizza has an 8-in. Diameter a large pizza has a 15-in. Diameter. The pizzeria charges the same price per square inch for
vlabodo [156]

The cost of large pizza is $24.62, a small pizza has an 8-in. diameter a large pizza has a 15-in. diameter the pizzeria charges the same price per square inch for both pizzas and the small pizza cost $7.

Step-by-step explanation:

The given is,

                A small pizza has an 8-inches in diameter

                A large pizza has a 15-inches in Diameter

                The small pizza cost $7

Step:1

                Area of smaller pizza,

                                        Area, A_{S} = \pi  r^{2}...................................(1)

                 Where, r - Radius of small pizza

                 From given, r=\frac{d}{2}

                                         = \frac{8}{2}

                                       r = 4 inches

                  Equation (1),

                                    A_{S} = \pi  4^{2}

                                          =(3.14)(16)                             ( ∵ \pi=3.14 )

                                          = 50.24 Square inches

Step:2

              Area of smaller pizza,

                                        Area, A_{L} = \pi  r^{2}...................................(1)

                 Where, r - Radius of small pizza

                 From given, r=\frac{d}{2}

                                         = \frac{15}{2}

                                       r = 7.5 inches

                  Equation (1),

                                    A_{S} = \pi  7.5^{2}

                                          =(3.14)(56.25)                             ( ∵ \pi=3.14 )

                                          = 176.625 Square inches

Step:3

            Cost of pizza per square meter,

                                                = \frac{Cost of small pizza}{Area of small pizza}

                                                =\frac{7}{50.24}

                                                = $ 0.1393 per square meter

                Cost of Larger pizza = Area of Larger pizza × Cost per square meter

                                                = (176.625)(0.139331)

                                                = $24.62

Result:

          The cost of large pizza is $24.62, a small pizza has an 8-in. diameter a large pizza has a 15-in. diameter the pizzeria charges the same price per square inch for both pizzas and the small pizza cost $7.
