Step-by-step explanation:
A compound used to remove permanent
hardness of water reacts with HCl to
produce NaCl, CO2 and H2O? Identify
the compound.
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

5) 36% of 68.1 is what?
Answer:
I'm pretty sure it's 24.516
Answer/Step-by-step explanation:
36% of 68.1 is 24.516.
1. To find a percentage of a number, turn the percentage into a decimal that is represented out of 100% where 1 is equal to 100%.
36% is represented as 0.36.
2. Now, multiply that decimal by the number.
68.1 x 0.36 = 24.516
This leaves us with the answer.

what is the equation of the line in slope intercept form
Answer:
y=3/2x-1
Step-by-step explanation:
Answer:
y=3/2x-1
Step-by-step explanation:
It goes up by 3 units and goes to the left by 2, 3/2. And the line intercepts the axis at -1.
The polygons below are similar. Find the scale factor of the SMALLER figure to the LARGER.
A. 5:6
B. 3:5
C. 5:8
D. 2:5
Answer:
A. 5:6
Step-by-step explanation:
The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.
Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.
Therefore:
Scale factor = 25:30
Simplify
Scale factor of the smaller figure to the larger = 5:6

The point (0, 0) is a solution to which inequality? A. y – 9 3x + 10 C. y – 9 > 3x – 10 D. y + 9 > 3x + 10
Let x = 0
Let y = 0
Look at choice A. There is a typo here. This is not an inequality. Where is choice B? No choice B given.
Let us play with choice C and D.
y - 9 > 3x - 10
0 - 9 > 3(0) - 10
-9 > 0 - 10...This is a true statement. We know that -9 is bigger than -10. Do you know why this is true?
How about D?
Again let y = 0 and x = 0.
0 + 9 > 3(0) + 10
9 > 0 + 10
9 > 10...This is untrue. We know that 9 is NOT BIGGER than 10.
Without knowing A and B, I figured out that choice C is true. We conclude that the point (0,0) AKA the origin is a solution to the inequality given by choice C.

f(x)=4x+7. Find the inverse of f(x).
A.{f^{ - 1}}\left( x \right) = \frac{{x - 7}}{4}f −1 (x)= 4x−7
B.{f^{ - 1}}\left( x \right) = 7 - 4xf −1 (x)=7−4x
C.{f^{ - 1}}\left( x \right) = \frac{{x - 4}}{7}f −1 (x)= 7x−4
D.{f^{ - 1}}\left( x \right) = 4x - 7f −1(x)=4x−7
it a i need for later
Answer:
Step-by-step explanation:
f(x) = y = 4x + 7
Solve for "x"
4x + 7 = y ⇒ x = [tex]\frac{1}{4}[/tex] y - [tex]\frac{7}{4}[/tex]
Exchange the places "x" and "y"
[tex]f^{-1}[/tex](x) = [tex]\frac{1}{4}[/tex] x - [tex]\frac{7}{4}[/tex]
or [tex]f^{-1}[/tex] (x) = [tex]\frac{x-7}{4}[/tex]
Find x when f(x) = 32.
Answer:
Step-by-step explanation:
i think you are forgetting to put the equation into your question because you cannot find x if y=32 x would be non existent

Kim ate 50% of candles in the bag if Kim ate 35 candies how many are left
Answer:
If Kim eats half of the bag, 50%, and 50% is 35 then the other 50%, the other half, is also 35. That means if Kim ate 50% of candies, 35, she has 35 candies left.

Step-by-step explanation:
A shift 5 units to the right, and then a shift 3 units up.
k = +3

h = -5
x+h shifts function left; x-h shifts function right, so 5 units right

Answer:
11/4800
Step-by-step explanation:
A worker has four different job offers, each with a contract for six years. Assuming the job descriptions are identical,
which offer will allow the worker to earn the most over six years?
O a starting salary of $49.000 with a 3% increase each year
O a starting salary of $51 000 with a 1% increase each year
O a starting salary of $48,000 with a 6% increase each year
a starting salary of $50,000 with a 2% increase each year
9514 1404 393
Answer:
$48,000 to start, with 6% raises
Step-by-step explanation:
The starting salaries are within a few percentage points of each other, so the majority of the difference in earnings will come because of the raises. The offer with the largest raise percentage is likely the best.
The earnings total can be figured as the sum of a geometric series with a first term of "starting salary" and a growth factor of (1+raise percentage). For starting salary 's' and raise percentage 'r', the total earnings in 6 years will be ...
S = s((1+r)^6 -1)/r
Here are the total earnings, in thousands, for each of the offers:
a) s = 49, r = .03, S = 316.95
b) s = 51, r = .01, S = 313.75
c) s = 48, r = .06, S = 334.82 . . . . best offer
d) s = 50, r = .02, S = 315.41
The worker can earn the most from a starting salary of $48,000 and 6% increases each year.
C) a starting salary of $48,000 with a 6% increase each year
Does anyone know what this means in relation to triangle proofs?
Answer:
If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent. This is an extension of ASA.

Two square rooms have a total floor area of 89m2. One room is 3m longer each way than the other. Find the dimensions of the two rooms. A. 5m square and 8m square B. 4m square and 6m square C. 5m square and 12m square D. 6m square and 8m square
Answer:
A
Step-by-step explanation:
Let the smaller room have an area of x^2
Let the larger room have an area of (x + 3)^2
(x+3) ^2 + x^2 = 89 Be careful not to make it 89^2.
x^2 + 6x + 9 + x^2 = 89 Expand the binomial squared
2x^2 + 6x + 9 - 89 = 0 Subtract 89 from both sides
2x^2 + 6x + 9 - 89 = 0 Combine
2x^2 + 6x - 90=0 Divide by 2
x^2 + 3x - 45 = 0 This factors.
(x + 9)(x- 5) = 0
X + 9 gives nothing useful
x - 5 = 0
x = 5
x + 3 = 5+3 = 8
So the answer is A

Divide. Write your answer as a fraction or mixed number in simplest form.
9 1/3 • 7
Answer:
65 1/3 or 196/3
Step-by-step explanation:
9 1/3 can be written as 28/3 (9 times 3 plus 1)
28/3 times 7/1 (because any whole number can have a 1 as the denominator)
Multiply top to top and bottom to bottom
28 times 7/ 3 times 1
196/3
Simplify to
65 1/3 but 196/3 will work out as well

Factorise:x2-3x-40 find this answer fast
This trinomial is in a special form that can be
factored into the product of two binomials.
So we set up two sets of parenthses.
As the first term, we have the factors of x², x and x.
For the second term, we have the factors of -40 that add to -3.
In this case, these factors are -8 and +5.
So our answer is (x - 8)(x + 5).
