Answer:

Step-by-step explanation:

Known facts:

Let us set up the equation:

p/c = 5/2 --> 2p = 5c --> 2p -5c = 0 -- equation 1

p = 9 + c --> p - c = 9 -- equation 2

Multiple equation 2 by 2

2p - 2c = 18 -- equation 3

subtract equation 1 and equation 3

-3c = -18

c = 6, so p = 15

So the total mass of both ingredients is 21 kg

2.                               600

4.                               700

6.          10,000

9.                            2500

Total $10,000    $3,800

A tabular analysis of transactions is an accounting-based analysis using tables.  A tabular analysis is a form of quantitative analysis.

b) Based on an analysis of the owner's equity columns, the net income is $6,200.

Net income = $6,200 ($10,000 - $3,800) or ($21,200 - $15,000)

Thus, the determination of the net income or net loss from the owner's equity columns is given as Ending equity + liabilities minus Beginning equity + liabilities (or revenue minus expenses).

Answer: The answer is P'(7, 17.5) and Q'(7, 3.5).

Step-by-step explanation:  Given that a line segment PQ is dilated with a scale factor of 3.5 where origin is the centre of dilation.

The end points of segment PQ are P(2, 5) and Q(2, 1).

Therefore, after dilation, the coordinates of the end points become

Thus, the coordinates of P' are (7, 17.5) and the co-ordinates of Q' are (7, 3.5).

Answer:

10.2 centimeters

Step-by-step explanation:

Given the following question:

A = 10cm
B = 2cm

In order to find the answer, we will use the Pythagorean theorem.

[tex]c=\sqrt{(a^2+b^2)}[/tex]
[tex]c=\sqrt{10^2+2^2}[/tex]
[tex]10^2=10\times10=100[/tex]
[tex]2^2=2\times2=4[/tex]
[tex]c=\sqrt{100+4}[/tex]
[tex]100+4=104[/tex]
[tex]\sqrt{104}[/tex]
[tex]\sqrt{104}=10.198039[/tex]
Round to the nearest tenth:
[tex]10.198039[/tex]
[tex]9>5[/tex]
[tex]10.2cm[/tex]

Your answer is "10.2 centimeters."

Hope this helps.

Answer:

12 km

Step-by-step explanation:

16km + 12 = 204

Subtract 12 from both sides:

⇒ 16km = 192

Divide both sides by 16:

⇒ km = 12

The given area of the [tex]52\frac{1}{2}[/tex] ft. by 33 ft. wall less the areas of the Windows and the Door give the area of the painted part of the wall as  [tex]\underline{1642\frac{9}{16}}[/tex] ft.²

The area of the painted part of the wall is [tex]\underline{1642\frac{9}{16}}[/tex] ft.²

The given dimensions of the wall are;

The width of the wall = [tex]52\frac{1}{2}[/tex] ft.

The height of the wall = 33 ft.

The painted area = Area of the wall - (Area of the widows + The door)

Which gives;

[tex]52\frac{1}{2} \times 33 - \left(6\frac{1}{4} \times 5\frac{3}{4} + 3\frac{1}{8} \times 4 + 9\frac{1}{2} + 4 \times 8 \right) = \mathbf{ 1642 \frac{9}{16}}[/tex]

The area of the painted part of the wall is [tex]\underline{1642\frac{9}{16}}[/tex] ft.²

Answer:

[tex] \frac{x + 2}{3x - 1} [/tex]

Step-by-step explanation:

x²-9 when factorized, would be

(x-3)(x+3)

Using a scientific calculator or manually, you can factorise the denominator of the same fraction which would be,

(3x-1)(x+3)

when it's fraction division, you must turn the sign into multiplication and use the reciprocal of the fraction.

[tex] \frac{(x - 3)(x + 3)}{(3x - 1)(x + 3)} \times \frac{x + 2}{x - 3} [/tex]

Now, you can cancel the similar terms which are,

(x-3) and (x+3)

then, you are left with your final answer as,

[tex] \frac{x + 2}{3x - 1} [/tex]

The stem-and-leaf plot that has two rows for each stem to display the​ data can be plotted.

Statistics is a mathematical tool defined as the study of collecting data, analysis, understanding, representation, and organization. Statistics is described as the procedure of collecting data, classifying it, displaying that in a way that makes it easy to understand, and analyzing it even further.

It is given that:

The data set is:

37, 36, 44, 50, 35, 58, 56, 67, 46, 63, 46, 37, 77, 45, 34, 44, 43, 81, ,53, 38, 73, 34, 38, 88, 34,,53, 41, 42, 45, 78

Stem Leaf

4         1 2 3 4 4 5 5 6 6

5         0 3 3 6 8

6         3 7

7         3 7 8

Answer:

[tex]\displaystyle \perp\:\frac{1}{2} \\ \parallel\:-2[/tex]

Step-by-step explanation:

You must first transform this standard equation to a Slope-Intercept equation like so:

[tex]\displaystyle y = mx + b \\ \\ -6x - 3y = -5 \hookrightarrow \frac{-3y}{-3} = \frac{6x - 5}{-3} \\ \\ \boxed{y = -2x + 1\frac{2}{3}}[/tex]

So, from this equation, we can tell that the y-intercept is at [tex]\displaystyle [0, 1\frac{2}{3}],[/tex]and the rate of change [slope] is −2, which is represented by [tex]\displaystyle m.[/tex]Now, we want the information on the rate of change ONLY. Perpendicular graphs have OPPOCITE MULTIPLICATIVE INVERCE rate of changes, which means we take the oppocite of −2, then flip it, to get [tex]\displaystyle \frac{1}{2}.[/tex]Parallel equations have SIMILAR rate of changes, so −2 remains as is.
