The 4 physical properties of solutions are:
1) Concentration
2) Solubility
3) Viscosity
4) Transparency
PHYSICAL PROPERTIES OF SOLUTIONIn chemistry, a solution is a homogeneous mixture of two or more substances. The four common physical properties of solutions are:
1) Concentration: The amount of solute present in a given amount of solvent, typically measured in molarity, molality, or mass percentage.
2) Solubility: The maximum amount of solute that can be dissolved in a given amount of solvent at a specific temperature and pressure.
3) Viscosity: The resistance of a fluid to flow, which can be affected by the presence of a solute.
4) Transparency or Opacity: The property of a solution by which it allows light to pass through it or not.
These are the 4 common physical properties of solutions, but there are many other physical properties that can be used to describe solutions depending on the context.

Answer:
1 equilateral triangle
Step-by-step explanation:
Given
Shape: Equilateral Triangle
Side length = 8cm
Required
Determine the number of triangles
From the question, we understand that the triangle is equilateral and the length of a side is 8cm.
This implies that the length of other sides will also be 8cm.
So, only one triangle can be constructed and their side lengths is 8cm.

Based on the information given, can you determine that the quadrilateral must be a parallelogram? Explain
The properties of a parallelogram:
1. opposite sides are parallel
2. opposite sides are equal in length
3. opposite angles are equal
4. diagonals bisect each other
if XN=NZ and NY=NW, then
XY=WZ and XW=YZ because the corresponding angles are equal = corresponding sides are equal
The opposite sides are parallel as well because the diagonals are equal (the vertical opposite angles are equal)

How many gallons of a 20% antifreeze solution and a 15% antifreeze solution must be mixed to obtain 30 gal of a 18% antifreeze solution? Round to the nearest gallon
Answer:
20% antifreeze solution = 18 gal
15% antifreeze solution = 12 gal
Step-by-step explanation:
Let
20% antifreeze solution = x
15% antifreeze solution = y
x + y = 30
0.20x + 0.15y = 30 * 0.18
0.20x + 0.15y = 5.4
x + y = 30 (1)
0.20x + 0.15y = 5.4 (2)
From (1)
x = 30 - y
Substitute x = 30 - y into (2)
0.20x + 0.15y = 5.4 (2)
0.20(30 - y) + 0.15y = 5.4
6 - 0.20y + 0.15y = 5.4
- 0.20y + 0.15y = 5.4 - 6
-0.05y = -0.6
y = -0.6/-0.05
y = 12 gal
Substitute y = 12 into (1)
x + y = 30 (1)
x + 12 = 30
x = 30 - 12
x = 18 gal
20% antifreeze solution = 18 gal
15% antifreeze solution = 12 gal

Actually Welcome to the Concept of the Surface areas and Volumes.
Since, we know that the lateral area of a Right circular cone is given as,
AL = πrl
here, l = slant height , r = radius of the circular base.
so now, we have to find first slant height to get the lateral surface area,
[tex]l \: = \sqrt{ {r}^{2} + {h}^{2} } [/tex]
here, r = 8 cm and h = 15,
hence,
[tex]l \: = \sqrt{64 + 225} = \sqrt{289} = 17cm[/tex]
hence, now we apply the formula,
AL = π(8) (17) cm^2
===> AL = 136 π cm^2

Answer:
x = 5 (please read the step by step explanation)
Step-by-step explanation:
So, I'm just going to solve for x because the instructions aren't too clear. I believe there is supposed to be an image attached to it, but seeing as I don't have that, I'll just solve for x and you can plug in with the values.
15x = 12x + 15
Same to both sides:
3x = 15
Isolate x:
x = 5
Just plug in those values and you'll be good to go! Have a good day!
Find the bank discount and proceeds using ordinary interest for a loan to michelle anders for 7,200 at 8.25% annual simple interest from august 8 to november 8
Answer:
$145.5
Step-by-step explanation:
Period, t = August 8.to November 8 = 3 months
Simple interest formula :
A = P(1 + rt)
A = final amount =. 7200
7200 = P(1 + (0.0825 * 3/12))
7200 = P(1 + 0.020625)
7200 = P(1.020625)
7200 = 1.020625P
P = 7200 / 1.020625
P = 7054.5009
Bank discount :
A - P
7200 - 7054.5009
= $145.4991
= $145.5

right.
9514 1404 393
Answer:
see attached
Step-by-step explanation:
When the parabola has a y^2 term it opens horizontally. (Positive and negative values of y give the same value of x.)
When the parabola has an x^2 term it opens vertically. (Positive and negative values of x give the same value of y.)
The sign is negative when the opening is down or to the left.

⅕m - 12 = -32
could someone solve this
Answer:
m = -100
Step-by-step explanation:
(1/5)m -12 = -32
add 12 on both sides
(1/5)m = -20
multiply both sides by 5
m = -100
Answer:
m = -100
Step-by-step explanation:
So in order to solve this equation we are going to have to convert 1/5m to a decimal, this will make it easier to solve the equation:
1/5m = 0.2m
Next we are going to take our 0.2m and place it within the equation where 1/5m is:
⅕m - 12 = -32 or 0.2m - 12 = -32
So now we are going to add 12 to both sides of the equal sign in the equation to segregate the 0.2m within the equation:
0.2m - 12 = -32 or 0.2m + (-12 + 12) = (-32 + 12)
making the equation look like this:
0.2m = -20
now we are going to divide 0.2 from both 0.2m and -20 to get the value of m:
0.2m/0.2 = -20/0.2
Thus getting the answer:
m = -100
So how do we know that -100 is the value of m? well we check our work of course by substituting -100 in place of m!
⅕(-100) - 12 = -32 or 0.2(-100) - 12 = 32
0.2(-100) - 12 = 32
-20 - 12 = -32
-32 = -32

28. ∠ABC=116
Step-by-step explanation:
Since BD bisects ∠ABC in each diagram, ∠ABD=∠DBC.
26.
∠ABD=∠DBC
5x+2=7x-6
2x=8
x=4
∠ABC=∠ABD+∠DBC
=5(4)+2+7(4)-6
=20+2+28-6
=44
27.
∠ABD=∠DBC
11x-12=8x+3
3x=15
x=5
∠ABC=∠ABD+∠DBC
=11(5)-12+8(5)+3
=55-12+40+3
=86
28.
∠ABD=∠DBC
9x-23=5x+13
4x=36
x=9
∠ABC=∠ABD+∠DBC
=9(9)-23+5(9)+13

how would i solve this please help
Answer:
x = -3Step-by-step explanation:
First let us get the equation of the coordinates
y-y0 = m(x-x0)
Using the coordinates ( - 3, 2 ), ( - 1, 0 )
m = 0-2/-1-(-3)
m = -2/2
m = -1
Substitute m = -1 and (-1, 0) into the formula
y - 0 = -1(x+1)
y = -x-1
f(x) = -x-1
Since f(x) = 2
2 = -x-1
-x = 2+1
-x = 3
x = -3
Hence the value of x is -3
