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.

Answer:

R = 10 cm

Step-by-step explanation:

The area of a spherical shape is given by :

[tex]A=4\pi r^2[/tex]

Where

r is the radius of the sphere

ATQ,

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.

The radius of each small bubble is 5 cm

Using the given condition,

[tex]4\pi R^2=4\times (4\pi r^2)\\\\R^2=4r^2\\\\R=\sqrt{4r^2} \\\\R=2r\\\\R=2\times 5\\\\R=10\ cm[/tex]

So, the radius of the large bubble is equal to 10 cm.

Answer:

20cm

Step-by-step explanation:

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.

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°

Omitted / Incomplete Question : Judy has read 4 Less than three times as many as Jason

Answer:Jason has read  7 mystery novels and Judy has read  17 mystery novels

Step-by-step explanation:

Total number of mystery books read by  Jason and Judy =24

Let Number of mystery books read by Jason=x

and  Number of mystery books read by Judy= 3x-4

So that the total number of book read by both of them will be expressed as

x +(3x-4) =24

x +3x-4 =24

4x=24+4

4x=28

x=28/4=7

There fore  Jason has read  7 mystery novels

and Judy = 3x-4 = 3 X 7- 4 =21-4=17mystery novels

Answer:

x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x+5)^2=21

Step 1: Simplify both sides of the equation.

4x^2+40x+100=21

Step 2: Subtract 21 from both sides.

4x^2+40x+100−21 =21−21 4x^2+40x+79=0

For this equation: a=4, b=40, c=79

4x^2+40x+79=0

Step 3: Use quadratic formula with a=4, b=40, c=79.

x= −b±√ b^2−4ac/2ax

= −(40)+√ (40)^2−4(4)(79)/2(4)

x = 40^2±√ 336/8

x= −5+1/2 √ 21 or x = −5+ − 1/2√ 21

Answer: x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21
