225 liters of water your family will having in 1 month when 2.5 liters of water for each day and 3 liters for adult.
Given that,
We have to find how much water your family will having in 1 month.
We know that,
What is amount of water in liters?When measured at its maximum density, which occurs at a temperature of about 4 °C, one litre of water has a mass of almost exactly one kilogram. As a result, one millilitre (1 mL), which is equal to 1000th of a litre, has a mass of approximately 1 g, and 1000 litres has a mass of approximately 1000 kg.
2.5 liters of water for each day
3 liters for adult
That means
1 month has 30 days
2.5×30=75
75×3=225
Therefore, 225 liters of water your family will having in 1 month when 2.5 liters of water for each day and 3 liters for adult.

Gene then reflected (-0.3, 7/10) over the y axis and then over the x axis what are the coordinates of the point after two reflections?
The coordinates of the point after the two reflections are (0.3,-7/10).
What is the reflection?A reflection is a mapping from an isometric hyperplane with a set of fixed points acting as the reflection's axis or plane from a Euclidean space to itself. A figure's reflection creates its mirror image of that figure in the plane or axis of the reflection.
Given that, the point (-0.3, 7/10) is reflected over the y-axis and then over the x-axis respectively.
The coordinates of the point after the reflection in the y-axis are:
(0.3, 7/10)
Now, the coordinates of the point after the reflection in the x-axis are:
(0.3, -7/10)
Hence, the coordinates of the point after the two reflections are (0.3,-7/10).

Ryan and Carlos decided to sell their cups of hot chocolate for $2.75. They sold 12 cups. They spent $9.45 on supplies that they will need to pay back to the bank.
How much profit did Ryan and Carlos make?
Answer:
$23.55
Step-by-step explanation:
First we will need to determine the total amount of sales Ryan and Carlos made. To do that we will multiply the amount of products sold by the product cost.
$2.75 x 12 = $33
Now we need to deduct the cost of supplies they need to pay back from their profits.
$33- $9.45= $23.55
Now we are left with Ryan and Carlos' total profit, which is $23.55

The domain and range of this square root function are: D: [–4, ∞) and R: [0, ∞).
What is a domain?In Mathematics, a domain can be defined as the set of all real numbers for which a particular function or relation is defined. This ultimately implies that, a domain is the set of all possible input values (x-values) for a function while a range is the set of all possible output values (y-values) of a function.
Based on the information provided, the function is represented as follows:
g(x) = √(x + 4)
Since a square root function doesn't exist for all negative values, the domain of this function is given by:
x + 4 ≥ 0
x ≥ -4
Domain = [-4, ∞]
Since we do not have a vertical translation, the range of this square root function is given by:

The slope of the line is found as follows;
(-5 - (-21))/(-1 - (-5)) = 4
The equation is y - (-5) = 4·(x - (-1)) = 4·x + 4
y = 4·x + 4 - 5 = 4·x - 1
y = 4·x - 1The y-intercept is (0, 4), the x-intercept is (4, 0)
The slope is therefore; (0 - 4)/(4 - 0) = -1
The equation is therefore; y - 0 = -1 × (x - 4) = -x + 4
y = -x + 4The y-intercept is (0, -1), the x-intercept is (4, 0)
The slope is therefore; (0 - (-1))/(4 - 0) = 1/4
The equation is therefore; y - 0 = (1/4) × (x - 4) = x/4 - 4/4 =
y = x/4 - 1The slope of the line is; [tex]\dfrac{-3\frac{3}{4} - \left(-\frac{3}{4}\right) }{4-1} = -1[/tex]

Here we need to find the graph of the given inequality.
To graph an inequality:
To graph the related boundary line. We have to replace the <, >, ≤ or ≥ sign in the inequality with = to find the equation of the boundary line.
Now, we have to identify at least one ordered pair on either side of the boundary line and substitute those (x, y) values into the inequality.
Then shade the region that contains the ordered pairs that make the inequality a true statement.
Here if points on the boundary line are solutions, then use a solid line for drawing the boundary line. This will happen for ≤ or ≥ inequalities.

The equation of the line y=2x+3 passes through which of the following points? (1,4)(-1,4)(2,3)(3,2)
Answer:
A
Step-by-step explanation:
Fill in X and Y for each of the equations until you find one that fits
The equation of the line y=2x+3 passes through the (1,4) point only.
The line gave y=2x+3.
In order to check whether the line passes through the points the following steps are:
A) (1,4)
Here x=1 , y=4.
We will put these values in the line y=2x+3.
4= 2(1)+3
4=4
As L.H.S=R.H.S, therefore this point (1,4) passes through the line.
B) (-1,4)
Here x=-1 , y=4.
We will put these values in the line y=2x+3.
4= 2(-1)+3
4= -2+3
4 [tex]\neq[/tex] 1
As L.H.S [tex]\neq[/tex]R.H.S, therefore this point (1,4) does not pass through the line.
C) (2,3)

We will put these values in the line y=2x+3.
3= 2(2)+3
3= 4+3
3 [tex]\neq[/tex] 7
As L.H.S [tex]\neq[/tex]R.H.S, therefore this point (2,3) does not pass through the line.
D) (3,2)

We will put these values in the line y=2x+3.
2= 2(3)+3
2= 6+3
2 [tex]\neq[/tex] 9
