What are the 4 physical properties of solutions?

Answer:

1/24  ≈0.042

Step-by-step explanation:

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

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

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!

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.

standard form is y=mx+b

to get there lets simplify the equation

y+2=(2/7)(x-1)   original in point slope form

y+2=(2/7)x-2/7      distribute 2/7

y=(2/7)x-16/7         subtract 2 from both sides, 2=14/7

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

Step-by-step explanation:

Answer:

Step-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

Answer:

26. ∠ABC=44

27. ∠ABC=86

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

=81-23+45+13

=116

It be 12 cause from the smaller one 2*4 would = to 8 and 5*4 also = to 20 so 3*4 = to 12.

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.

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

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)

This was a word pasta but hope this helps

The opposite sides are parallel because the diagonals are equal.

From the given parallelogram, you can see that the diagonals bisect each other.

Also if XN=NZ and NY=NW, then XY=WZ and XW=YZ show that the corresponding angles are equal

Also from the diagram, the opposite sides are parallel because the diagonals are equal (the vertical opposite angles are equal).
