Ths solubility curve is used to show the amount of salt dissolved (solubility).
What is the solubility curve?The solubility curve is a depiction of the solubility of a substance plotted against its temperature. It can be used most times to show the solubility of a susbtance at different temperatures. This question is incomplete hence so we can not be able to obtain the solubility of the salt at this temperature.
If the solubility curve has been shown in the graph, then we can be able to obtain the solubility of the salt from the data shown on the plot.

Answer:
[tex](2c+a+3b)(2c-a-3b)[/tex]
Step-by-step explanation:
Given expression: [tex]4c^2-a^2-6ab-9b^2[/tex]
Factor [tex]-a^2-6ab-9b^2[/tex]
[tex]\implies -(a^2+6ab+9b^2)[/tex]
[tex]\implies -(a+3b)(a+3b)[/tex]
[tex]\implies -(a+3b)^2[/tex]
Factor [tex]4c^2[/tex]
[tex]\implies(2c)(2c)[/tex]
[tex]\implies (2c)^2[/tex]
Therefore,
[tex](2c)^2-(a+3b)^2[/tex]
Difference of Two Squares: [tex]x^2-y^2=(x+y)(x-y)[/tex]
[tex]x^2=(2c)^2\implies x=2c[/tex]
[tex]y^2=(a+3b)^2 \implies y=a+3b[/tex]
Therefore,
[tex]\implies (2c + a + 3b)(2c - (a + 3b))[/tex]
[tex]\implies (2c+a+3b)(2c-a-3b)[/tex]
Answer:
(2c - a + 3b)(2c + a + 3b)
Step-by-step explanation:
4c² - a² - 6ab - 9b²
= 4c² - (a² + 6ab + 9b²) ← the terms in the parenthesiis are a perfect square )
= 4c² - (a + 3b)² ← this is a difference of squares which factors in general as
a² - b² = (a - b)(a + b) , then
= (2c)² - (a + 3b)²
= (2c - (a + 3b) )(2c + (a + 3b) )
= (2c - a - 3b)(2c + a + 3b)

Answer:
Step-by-step explanation:
This is a proportion question which is 2 ratios which are equal to one another. If 3 of the 4 parts are known, the 4th part can be calculated.
36 liters.
36 km/3 Liters = x / 36 multiply both sides by 36
36*36 / 3 = x
1296/3 = x
x = 432 km
So on 36 L he can go 432 km
3 liters
Given as 36 km
48 liters
36km/3 liters = x / 48 liters Multiply both sides by 48
48*36/3 = x
576 km = x
So on 48 liters, he can go 576 km
132 liters
36 km/ 3 liters = x/132
x = 1564 km
On 132 liters Pat can go 1564 km

The concept of this question belongs to sum of internal angles of triangle and Linear pair of angles .
Solution : -Firstly , we are finding value of angle y. So sum of Angle 1 , Angle 2 and Angle y is equal to 180° because sum of all angles of internal triangle is 180°. So :
44° + 76° + y° = 180°120° + y° = 180°y° = 180° - 120°y° = 60°Therefore , value of angle y is 60° .
Now , we are finding the value of x :
As we know angle 3 ( y ) and angle 4 ( x ) is equal to 180° because they form linear pair . So :
60° + x° = 180°x° = 180° - 60°x° = 120°Therefore, value of angle x is 120° .

In a study of the performance of a new engine design, the weight of 22 aircrafts (in tons) and the top speed (in mph) were recorded. A regression line was generated and shown to be an appropriate description of the relationship. The results of the regression analysis are below.
Part A: What is the LSRL based on the analysis provided? Make sure to identify what the variables represent in the context of the problem. (4 points)
Part B: What is the predicted value for the top speed of an aircraft if its weight is 100 tons? Show your work. (6 points)
The LSRL is the Least Squares Regression Line of the new engine design performance
The LSRL is: y = 11.6559 + 3.47812x The predicted top speed when the weight is 100 tons is 359.4679How to determine the LSRL?This is the equation of the Least Squares Regression Line.
From the calculation summary, we have the following parameters:
Coefficient of constant = 11.6559Coefficient of Weight = 3.47812So, the LSRL is:
y = 11.6559 + 3.47812x
Where y represents the predicted volume and x represents the weight.
The predicted value when the weight is 100 tonsIn (a), we have:
y = 11.6559 + 3.47812x
Substitute 100 for x
y = 11.6559 + 3.47812 * 100
Evaluate
y = 359.4679
Hence, the predicted top speed when the weight is 100 tons is 359.4679

See belowStep-by-step explanation:
Initial cost = $52
Markup for operting expences = 34%
$52 + 34% = $52*1.34 = $69.68Markup for profit = 6%
69.68 + 6% = 69.68*1.06 = 73.86 (rounded)a) The selling price is $73.86
b) The reduced price is:
