Answer:
Well by looking at the products,it must be sodium bicarbonate (NaHCO3)
Step-by-step explanation:
but then sodium bicarbonate does not remove permanent hardness of water,that compound is washing soda(Na2CO3) which should not be confused with NaHCO3. So as it would appear,the premise of the question is wrong but there is a compound that reacts with HCl to give those products

Explain how to find the estimated sum of 5/8 + 2/9 .
Answer:
0.847Step-by-step explanation:
In this expression, you would have to use the PEMDAS method. First divide, so (5 divided by 8) + (2 divided by 9).
The answer you would get is: (0.625) + (0.222)
The final answer is: 0.847

PLEASE HELP ME THIS IS FOR GEOMETRY I CANT FIGURE THIS OUT
9514 1404 393
Answer:
40°
Step-by-step explanation:
Triangles QRS and QTS are congruent (HL), so the marked angles are also congruent:
3x +2 = 4x -4
6 = x
Then the total angle measure of angle RST is ...
(3x +2) +(4x -4) = 7x -2 = 7(6) -2 = 40 . . . degrees
m∠RST = 40°
Which set of points includes all of the solutions for y = negative three halves times x plus two?
line going through 0 co
(x, y) for all real numbers
(x, negative three halves times x plus two) for all real numbers
(−2, 5), (0, 2), and (4, −4)
(−4, 8), (−2, 5), (0, 2), (2, −1), (4, −4)
Given:
[tex]y=-\dfrac{3}{2}x+2[/tex]
To find:
The set of points that includes all of the solutions for the given equation.
Solution:
From the given equation, it is clear that y-values depend on the x-values.
If x is a real number, then y-values are real numbers such that [tex]y=-\dfrac{3}{2}x+2[/tex].
So, the set of points that includes all of the solutions for the given equation is defined as [tex]\left(x,-\dfrac{3}{2}x+2\right)[/tex] for all real numbers.
Therefore, the correct option is B.
round off 0.02435 to three significant and add to 0.00732
Answer:

Step-by-step explanation:
An experimenter studies vision in low light by
having participants sit in a darkened room for
either 5, 15, or 25 minutes and then testing their
ability to correctly identify 20 objects. (a) What is
the independent variable here? (b) What are the
conditions? (c) What is the dependent variable?
(d) You would use the scores from which variable
to create a frequency distribution?
Answer:
Independent variable- time spent in the dark room
Dependent variable - number of objects correctly identified
Conditions of the experiment- low light environment and lighted environments
Scores from the independent variable are used to construct the frequency distribution
Step-by-step explanation:
The independent variable is the factor that is being manipulated in an experiment and this time it is the time spent in a darkened room.
The dependent variable is the response variable, in this case, the number of objects correctly identified.
The experimental conditions involved bringing people from a lighted area into a darkened room.

How many times the volume of the small cube is the volume of the large cube? Small cube 3x large cube 6x
Answer:
8 times
Step-by-step explanation:
volume if cube = l³
volume of small cube = (3x)³ = 27x³
Volume of Large cube = (6x)³ = 216x³
216x³/27x³ = 8
The volume of large cube = 8 × Volume of small cube

The LA Dogers hit the most home runs in 2014. The number of home runs accounted for 6% of the entire major league Baseball home run count.If 583 total home runs were hit, then how many did the LA Dogers hit
Given:
Total number of home runs = 583
Home runs hit by LA Dogerse = 6% of the total home runs
To find:
The number of home runs hit by LA Dogers.
Solution:
We have,
Home runs hit by LA Dogerse = 6% of the total home runs
[tex]=\dfrac{6}{100}\times 583[/tex]
[tex]=\dfrac{3498}{100}[/tex]
[tex]=34.98[/tex]
[tex]\approx 35[/tex]
Therefore, LA Dogerse hits about 35 home runs.

Factorise
2х^2 — 3x— 14
Answer:
(x + 2)(2x - 7)
Step-by-step explanation:
Given
2x² - 3x - 14
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 14 = - 28 and sum = - 3
The factors are - 7 and + 4
Use these factors to split the x- term
2x² + 4x - 7x - 14 ( factor the first/second and third/fourth terms )
= 2x(x + 2) - 7(x + 2) ← factor out (x + 2) from each term
= (x + 2)(2x - 7)
Thus
2x² - 3x - 14 = (x + 2)(2x - 7) ← in factored form
which number in scientific notation represents 9,832,000?
solve for x I need help on questions 5 & 6
Answer:
#5 x=8, #6 x=5
Step-by-step explanation:
Theyre vertical so for number 5 you would have the equation
5x+15=55
-15 -15 from both sides
5x=40
divide by 5 from both sides and you get
x=8
Same thing vertical so you would have
16x+7=87
-7 -7 from both sides
16x=80
divide by 16 from both sides
x=5

Answer:
Espero y esto te ayude :) si me falto algo lo siento.
Step-by-step explanation:
Si se oferta un producto al 10% de descuento, esto significa que el precio final del producto será 90% del precio original. Para hallar estos datos, debemos usar una regla de tres, de la siguiente forma:
100% 90%
-------------------- → ---------------------------
Precio Original Precio con Descuento?
SARAPES
- Ana: descuento (14), precio rebajado 126
Precio rebajado = 140.90 / 100 = 126
Descuento: 140 - 126 = 14
- Javier: descuento (8), precio rebajado 72
Precio rebajado = 80.90 / 100 = 72
Descuento: 80 - 72 = 8
ARETES
- Luis: descuento (5), precio rebajado 72
Precio rebajado = 50.90 / 100 = 45
Descuento: 50 - 45 = 5
- Ana: Precio original (60) , descuento (6), precio rebajado 54
Precio original: X.0,10 = 6
X = 60
Precio rebajado: 60 - 6 = 54
- Javier: Precio original (40) , descuento (4), precio rebajado 36
Precio original: X.0,10 = 4
X = 40
Precio rebajado: 40 - 4 = 36
