Brooke has a cylinder metal tin where he keeps his coins. The radius of the base is 5.5 inches and the height is 4 inches what is the area of a vertical cross section of the cylinder through the center of the base?

Answers

Answer:

44 square inches.

Step-by-step explanation:

radius of the base = 5.5 inches

height of the cylinder = 4 inches

The shape of the vertical cross section of the cylinder through the center of the base would give a rectangle with length of 2r, and its width is the height of the cylinder.

Area of the vertical cross section = height x diameter

diameter of the cylinder = 2r

                                        = 2 x 5.5

                                        = 11 inches

The diameter of the cylinder is 11 inches.

Area of the vertical cross section = 4 x 11

                                        = 44 square inches.

The area of a vertical cross section of the cylinder through the center of the base is 44 square inches.

Answers

B .......................................

120l NaBr solute is saturated at 70 degrees. In this case option b is correct when  saturated at 70 degrees.

NaBr is the chemical formula for sodium bromide. It is an inorganic compound composed of sodium (Na) and bromine (Br). Sodium bromide is a white, crystalline solid that is highly soluble in water.

In terms of its properties and uses, sodium bromide has various applications. It is commonly used in the pharmaceutical industry as a sedative and anticonvulsant drug. Sodium bromide is also used in the oil and gas industry as a completion fluid in well drilling and workover operations. Additionally, it finds applications in photography as a component of some film developers.

As a salt, sodium bromide dissociates into sodium ions (Na+) and bromide ions (Br-) when dissolved in water. These ions can participate in various chemical reactions and have different effects depending on the specific application or purpose.

Find the measure of the angle indicated... please help

Answers

Answer:

Step-by-step explanation:

41). Measure of an external angle of a triangle is equal to the sum of teh opposite two angles.

140° = (13x + 9)° + (5x + 5)°

140 = 18x + 14

18x = 140 - 14

18x = 126

x = 7

m∠R = (13x + 9)

        = 13×7 + 9

        = 100°

42). m∠DCA = m∠E + m∠D

126° = (6x + 2)° + (5x + 3)°

126 = 11x + 5

11x = 126 - 5

11x = 121

x = 11

m∠D = (5x + 3)

         = 5(11) + 3

         = 58°

43). m∠DPQ = m∠Q + m∠R

11x + 3 = 70° + (x + 13)°

11x + 3 = x + 83

11x - x = 83 - 3

10x = 80

x = 8

m∠R = (x + 13)

        = 21°      

44). m∠QST = m∠T + m∠U

13 + 13x = 100 + (3x + 3)

13 + 13x = 3x + 103

13x - 3x = 103 - 13

10x = 90

x = 9

m∠U = 3x + 3

        = 3(9) + 3

        = 27 + 3

        = 30°

"The price of books for our students is justgetting higher and higher and, combined with the rising cost of tuition, it's killing these kids," said PeterJason, Ph.D. "Remember, students are one of the poorest groups of people in America. Almost half of themhave at least one part-time job. In fact, one of my students has three jobs. She is a part-time sales clerk at aclothing store three days a week, then works three evenings a week as a pizza cook, and on weekends shedoes manicures at a beauty salon. And she still manages to have a high GPA and go to school full-time."Textbook prices are traditionally high. Adding to that problem, many college instructors changetextbooks year after year; they either upgrade to a new edition or switch to an entirely different textbook.This further hurts students because if an instructor no longer uses a particular textbook, that book has noresale value.Dr. Jason decided to make life a little easier and a lot cheaper for his students by writing his own bookon public speaking. "Many books have an increased price because of bells and whistles: CD-ROMs, lots ofcolor photographs, and lots of graphics. I talked to my students, and many of them, like me, prefer to keepthings simple. So, during a sabbatical a few years ago, I wrote my own textbook. I made sure that it wasn'tlong-winded. I called it Successful Public Speaking: How To Be Brief, Concise, and to the Point."Compared to most other public speaking primers, mine is half the number of pages, and one-third theprice. That is, $30 instead of $90. Plus, it is published in a three-ring binder format. So, when I wrote asecond edition last year, students only had to buy the 35 new pages and delete 35 of the original pages. Foronly $7.00, they had upgraded to the new edition.
