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.

cat face x+4/5=45 sa il aflu pe x
Given:
The equation is
[tex]x+\dfrac{4}{5}=45[/tex]
To find:
The value of x.
Solution:
We have,
[tex]x+\dfrac{4}{5}=45[/tex]
Isolating the variable, we get
[tex]x=45-\dfrac{4}{5}[/tex]
[tex]x=\dfrac{225-4}{5}[/tex]
[tex]x=\dfrac{221}{5}[/tex]
[tex]x=44.2[/tex]
Therefore, the value of x is 44.2.

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. Each small bubble has a radius of 5 centimeters. What is the radius of the large bubble?
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:
5cm+5cm+5cm+5cm=20cm
PLEASE HELP I WILL MARK YOU BRAINLIEST determine the exact and approximat solutions for 4(x + 5)^2 = 21 show your steps
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

Together Jason and Judy have read 24 mystery novels. Judy has read less than three times as many as Jason. How many mystery novels have each of them read.
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

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