The mean age of 5 people in a room is 39 years.
A person enters the room.
The mean age is now 36.
What is the age of the person who entered the room?​

Answers

Answer:

fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help

Answer:

The age of the person who entered the room is 21.

Step-by-step explanation:

Mean of 5 peoples = 39

i.e.

Sum / 5 = 39

Sum = 39 x 5

Sum = 195

Mean after one person enters the room = 36

Let x be the age of the new person.

Then

Mean = (Sum + x)/ 6

36 = (195 + x)/6

36 x 6 = 195 + x

216 = 195 + x

x = 216 - 195

x = 21

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°

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.

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.
