Moles of CO2 = 0.024dm³ / (24dm³/mol) = 0.001mol
Hence 0.001mol of XCO3 is required.
plz i have 24 hrs to answer this... Pool X currently has 1,200 gallons of water and is being drained at a rate of 15 gallons per minute. Pool Y is currently empty and is being filled at a constant rate of 25 gallons per minute. Which inequality represents the situation when the amount of water in Pool Y is greater than the amount of water in Pool X? 1,200 - 15x > 25x
1,200 + 15x > 1,200 + 25x
1,200 - 15x < 25x
1,200 + 15x < 25x
=======================================================
Explanation:
Pool X has 1200 gallons of water in it. It is being drained at a rate of 15 gallons per minute. If lowercase x is the number of minutes, then it has 1200-15x gallons left in the pool.
Consider after 1 minute we have x = 1, so,
1200-15x = 1200-15*1 = 1200-15 = 11185
Then after 2 minutes we have x = 2, which means,
1200-15x = 1200-15*2 = 1200-30 = 11170
is the amount left over in gallons.
----------------
In contrast, Pool Y is empty and we add 25 gallons per minute. So we start with 0 and add on 25x getting 0+25x = 25x as the expression representing the amount of gallons of water in Pool Y
-----------------
So we found these two expressions
1200-15x25xto represent the amount of water (in gallons) for Pool X and Pool Y respectively.
We want to know when Pool Y will have more water. So we get to this final answer
1200 - 15x < 25x
It is in the form A < B, where A is the amount of water in Pool X and B is the amount of water in Pool Y.

can somebody teach me how to do this 1 math question, its about solve for the area! WILL Give Brainiest!
Answer:
area is 100m bc u do 10 times 10
Step-by-step explanation:
Answer:
139.27 meters squared
Step-by-step explanation:
So what you're doing is calculating the square's area and half of the circle's area.
The square's area is 100m^2 since 10*10=100
For the circle part, you use πr^2. You know the diameter of the circle, and radius is half of the diameter, so 10/2=5.
π*5^2 = 78.54 m^2
Since you have half of a circle you divide this by 2.
39.27
Finally you add your two areas together
100+39.27=139.27 meters ^2
A recipe says to use 3 cups of flour to make 48 cookies. What is the constant proportionality that relates the number of cookies, y, to the number of cups of flour used, x?
Answer k=16
A recipe says to use 3 cups of flour to make 48 cookies.
the number of cookies made, y, to the number of cups of flour used,x .
Than
y = kx
Where k is the constant of proportionality.
48 = 3k
k = 16
Therefore the constant of proportionality is 16.

Yeah my math class is coocoo, and im stuck on this. Im slow. Help me :(
Answer:
y=4x+4
Step-by-step explanation:
i was learning this not too long ago so i hope this helps y=mx+b aka slope is 4 and then for b you put the y intercept aka 4 and then the x and y factors you csn leave blank cause you dont have them
An equation of the line that passes through (-1,4) and is perpendicular to the line given in the graph is y=3x+7.
The coordinates from the line on the graph is (-3, 4) and (3, 2).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
Now, slope =(2-4)/(3+3)
= -2/6
= -1/3
Substitute m=-1/3 and (x, y)=(-3, 4) in y=mx+c, we get
4=-1/3 (-3)+c
⇒ c=3
The slope of a line perpendicular to given line is m1=-1/m2
So, slope =3
An equation of the line that passes through (-1,4)
Now, 4=3(-1)+c
c=7
Put m=3 and c=7 in y=mx+c, we get
y=3x+7
Therefore, an equation of the line that passes through (-1,4) and is perpendicular to the line given in the graph is y=3x+7.

Answer:
x = 25
Step-by-step explanation:
From the picture attached,
ΔABC and ΔADE are the similar triangles.
Therefore, their corresponding sides will be in the same ratio.
[tex]\frac{\text{AB}}{\text{AD}}=\frac{\text{AC}}{\text{AE}}=\frac{\text{BC}}{\text{DE}}[/tex]
[tex]\frac{\text{AB}}{\text{AD}}=\frac{\text{BC}}{\text{DE}}[/tex]
And AB = AD + DB
= 2(AD) [Since, AD = DB]
By substituting these values,
[tex]\frac{\text{2AD}}{\text{AD}}=\frac{\text{34}}{\text{(x-8)}}[/tex]
2 = [tex]\frac{34}{x-8}[/tex]
x - 8 = [tex]\frac{34}{2}[/tex]
x - 8 = 17
x = 17 + 8
x = 25

Angela has 5 fewer quarters than twice the number of her dimes. If d represents
the number of dimes Angela has, which expression represents the total number of
Angela’s quarters and dimes?
A. 2d – 5
B. 5 – 2d
C. d + (2 – 5d)
D. d + (2d – 5)
PLSSSSS SHOW YOUR WORK PLSSS
Answer:
D
Step-by-step explanation:
We will let d represent the amount of dimes Angela has.
Angel has 5 fewer quarters than twice the number of dimes.
Twice the number of dimes will be 2d.
Then, 5 fewer will yield 2d-5.
Therefore, the amount of quarters Angela has is 2d-5.
Then, the total amount of coins (dimes and quarters) together, will be:
[tex]d+(2d-5)[/tex]
The first part is the amount of dimes.
And the second part is, as we determined, the amount of quarters.
Therefore, our answer is D.

Which statement is true about the value of |-5|? It is the distance that -5 is form 0 on the number line. It is the distance that -5 from 5 on the number line. It is less than 5. It is greater than 5.
Answer: It is the distance that -5 is form 0 on the number line
Step-by-step explanation:
We can define the absolute value of any number:
IxI as:
"The distance between the point x and the origin in the coordinate axis"
If we are in one dimension, x is just a value, and the coordinate axis will be a number line.
Then we could rewrite this as:
"is the distance between the value x and the 0 in the number line"
So:
IxI = x if x > 0
IxI = -x if x < 0.
Then:
I -5 I
Is the distance between the number -5, and the 0 in the number line, and this is:
I - 5 I = 5.
The correct option is:
"It is the distance that -5 is form 0 on the number line"
Answer:
Answer: It is the distance that -5 is form 0 on the number line
