What is 50% of $68? Show all of your work. Use the percent proportion model shown below to set up the equation before you calculate the answer.
Answer:
$34
Step-by-step explanation:
50% is half of 100%
(Because 50% x 2 = 100%)
Thus, half the money ($68) to find 50%.
So, 68÷2 = 34
Final answer is $34
Or
50/100 x $68 =$34

Help please I’ve been trying to figure this out
The floating cities appear to float pretty high off the surface to you and you'd like to know just
how far off the surface they are. Zolonians measure distance in bedars instead of kilometers. To convert bedars to
kilometers the formula is 16km + 12 = bedars. If Zolon's cities float 204 bedars in the air, how many kilometers off the
surface of Zolon is that?
Answer:
12 km
Step-by-step explanation:
16km + 12 = 204
Subtract 12 from both sides:
⇒ 16km = 192
Divide both sides by 16:
⇒ km = 12

How do I work this out? Someone explain fully please
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]

What is the area of the painted part of the wall?
52 1/2 x 33 = Wall
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
How can the area of the painted part be calculated?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]

One of the legs of a right triangle measures 10 cm and the other leg measures 2 cm.What is the measure of the hypotenuse?
Answer:
Step-by-step explanation:
By the Pythagorean theorem, the square of one leg plus the square of the other leg is equal to the square of the hypotenuse.
so:
hypotenuse = [tex]\sqrt{2^{2}+10^{2} }[/tex]= 10.198 (approximated)

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:

Cash, Accounts Receivable, Supplies, Equipment, Accounts Payable, Owner's Capital,
Owner's Drawings, Revenues, and Expenses.
(b) From an analysis of the owner's equity columns, compute the net income or net loss
for April.

What is a tabular analysis?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).

Can somebody explain how do I do this?
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.

A dilation with a scale factor of 3. 5 and centered at the origin is applied to PQ¯¯¯¯¯ with endpoints P(2, 5) and Q(2, 1)
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).
