A real-estate agent earns a commission on a house she sells. Her commission 5% on the first $500,000 ofthe sale price of the house. She then earns a 6% commission for the amount above $500,000 of the salé price of the house. How much commission did the agent earn if she sold a house for $585,000?
Answers
Percent: 6% = 0.06
Now we will multiply the cost of the house by the percentage to find the commission amount:
1) 0.06(585,000) = 35,100
The total amount the agent will receive would be $35,100.

Answer:
The result of the subtraction is [tex]\(57\).[/tex]
Explanation:
To subtract the numbers given, we need to add all the positive numbers and then subtract the sum of the negative numbers.
Positive numbers: [tex]\(6 + 4 + 6 + 4 + 5 + 5 + 6 = 36\)[/tex]
Negative numbers: [tex]\(-6 - 6 - 4 - 1 - 4 = -21\)[/tex]
Subtracting the sum of the negative numbers from the sum of the positive numbers:
[tex]\(36 - (-21) = 36 + 21 = 57\)[/tex]
So, the result of the subtraction is [tex]\(57\).[/tex]

A hole was dug 2 3/8 feet deep for a fence post. The fence post is 6 feet long. How far above the ground will the fence post be when it is placed in the hole? Enter your answer as a mixed number, in simplified form, in the box.
PLEASE ANSWER ASAP
Answers
[tex]\text{Answer: The fence post will be }3\frac{5}{8}\ feet\text{ far above the ground when it is placed in the hole.}[/tex]
Explanation:
Since we have given that
Length of hole dug for a fence post is given by
[tex]2\frac{3}{8}\ feet=\frac{19}{8}\ feet[/tex]
Length of the fence post = 6 feet
we need to find the length of the fence post above the ground is seen when it is placed in the hole.
So, Length of the fence post above the ground is given by
[tex]6-\frac{19}{8}\\\\=\frac{48-19}{8}\\\\=\frac{29}{8}\\\\=3\frac{5}{8}\ feet[/tex]
[tex]\text{Hence, the fence post will be }3\frac{5}{8}\ feet\text{ far above the ground when it is placed in the hole.}[/tex]

Triangles are in total 180 degrees. The two triangles are basically 1 triangle split in half. If the triangle share the same side, has similar angles (shown by the curves on both sides at the top(Angle BAC and CAB), and has similar sides(shown by the hashes made in the lines AC & AB), you can conclude 'x' as a 90 degree angle.
To find y:
The measurment of the angle DCA is 47 degrees. For x, we concluded the answer to be 90 degrees, making the other side of the line 90 degrees as well.Since a triangle is 180 degrees, we can add 47 and 90 to get 137. Taking that answer, we subtract it from the value of 180 degrees to get 43 degrees. So y equals 43.

The problem deals with the segment addition postulate. By setting up and solving the relevant equation (2x + 7 = 6x - 5), we find that x = 3. Therefore, the length of AB = 6.
Explanation:The subject of this question is segment addition postulate in mathematics. Given that B is between A and C, it implies that AB + BC = AC. From the problem, it's given that AB = 2x, AC = 6x - 5 and BC = 7. Setting up the equation would yield 2x + 7 = 6x - 5. Solving this equation gives us x = 3. Therefore, by substituting x=3 in AB = 2x we find that AB = 6.

The table shows the number of balls, by sport, in the gym.
A. The ratio of soccer balls to all balls is 4:25
B. For every 10 balls in the gym, 3 are basketballs
C. None of the above
Answers
All the balls combined are 50 balls
8 of the balls are soccer balls so that makes the ration 8:50
In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.
The ratio of soccer balls to all balls is 4:25.
Given that;
The table shows the number of balls, by sport, in the gym.
Now, We have;
Number of soccer balls = 8
And, Total number of balls = 50
Hence, The ratio of soccer balls to all balls is,

Find the measure of angle KLM.
This is an EXPLAIN YOUR THOUGHTS question which means you need to:
1) include the properties, theorems, etc. that you used to set up an equation.
2) Show the euqation you used to solve for x and thus solve for the angle measure of KLM
Answers
-------------------------------------
-------------------------------------
We'll use these properties:
Property 1: Linear pairs of angles are adjacent (touching) and supplementary. They form a straight angle. By definition they are supplementary meaning they add to 180 degrees.
Property 2: For any triangle, the three angles always add to 180 degrees
-------------------------------------
We need the measure of angle KLJ in terms of x.
Notice how KLJ and KLM form the straight angle JLM (which is 180 degrees). So we'll use property 1 mentioned above. Let's isolate angle KLJ to get...
(angle KLM) + (angle KLJ) = 180
(20x+4) + (angle KLJ) = 180 ... use the substitution property to replace angle KLM with its algebraic expression
angle KLJ = 180 - (20x+4)
angle KLJ = 180 - 20x-4
angle KLJ = -20x + 176
-------------------------------------
Now that we know angle KLJ, we can use this angle along with the angles JKL and KJL. Basically we're focusing on the smaller triangle on the left (the obtuse triangle)
Add those three angles up and set the result equal to 180 degrees. I'm using property 2 now.
(angle KLJ) + (angle KJL) + (angle JKL) = 180
(-20x+176) + (6x+4) + (8x+18) = 180
Therefore the equation we need to solve is: (-20x+176) + (6x+4) + (8x+18) = 180
Let's do so...
(-20x+176) + (6x+4) + (8x+18) = 180
-20x+176 + 6x+4 + 8x+18 = 180
(-20x+6x+8x)+(176+4+18) = 180
-6x+198 = 180
-6x+198-198 = 180-198
-6x = -18
-6x/(-6) = -18/(-6)
x = 3
After solving for x, we get x = 3
Let's use this to find the measure of angle KLM
angle KLM = 20*x+4
angle KLM = 20*3+4
angle KLM = 60+4
angle KLM = 64
The measure of angle KLM is 64⁰
What are supplementary angles?Supplementary angles are two angles whose measures add up to 180⁰ In other words, when placed adjacent to each other, they form a straight line.
From the figure
Given
<J = (6x+4)⁰
<K = (8x + 18)⁰
<KLN = 180 -(20x +4) (supplementary angles)
In Triangle KLN
<J + <K + <L = 180⁰(sum of angles in triangle)
Substitute
(6x + 4) + (8x + 18) = (20x + 4)(sum of 2 int.<s is equal to exterior<)
Simplifying
6x + 8x - 20x = 4 - 4 - 18
14x -20x = -18
-6x = -18
x = -18/-6
= 3
Substitute into (20x + 4) to find the measure of angle KLM
20x +4 = 20(3) + 4
= 60 + 4
= 64⁰
The measure of angle KLM is 64⁰

Choice [A]: "whole number only" ; is incorrect; since any decimal value/ decimal-containing value — including this given value: "8.2" — is not a "whole number" ; and NOT an integer.
Thus, we can eliminate Choices: [D]: and [B] ; and we are left with:
"Choice: [C]: "Rational numbers only".
Note: "8.2" is a rational number; since the number is real; and since the number is not "irrational". An "irrational number" would mean that the resulting decimal form would be "non-terminating" AND "non-repeating".

Choice: [C]: is: "rational numbers only". Note that: "5" ; is, in fact, a "rational number"; however, take note of the word: "only"; (as mentioned in: "Answer choice: [A]" .

solve the system of equation-5x+2y=9 y=7x
Answers
y = 5x/2 + 9/2
(I don't know if this is correct)
Hope this helps!
The system of equations -5x + 2y = 9 and y = 7x is solved using substitution, yielding the solution x = 1 and y = 7.
To solve the system of equations -5x + 2y = 9 and y = 7x, we can use substitution since the second equation gives us 'y' in terms of 'x' directly. We substitute 7x in for y in the first equation:
-5x + 2(7x) = 9
-5x + 14x = 9
9x = 9
x = 1
Now that we have the value for x, we can find y using the second equation:
y = 7(1)
y = 7
Therefore, the solution to the system of equations is x = 1 and y = 7.

The 16 isn’t in the equation because they are coming back.
So your answer is 220.
You have 200 people in a race, and 20 drop out. Meaning, you must subtract:
200 - 20 = 180
Next, 16 take a break, so you must subtract again:
180 - 16 = 164
Finally, 40 people are added back, so, you must add:

If Jill is playing a game with a single die (singular form of dice), what are the chances she would throw any one number twice in a row?

A common mistake made on problems like these is to say the answer is 1/12.
The only roll that really matters in this problem is the second one. This is because the first role only determines what the second role must be. Therefore, you only take the probability of rolling one fixed number in one roll, which would be one in six.
I appreciate the fact that you said die in your question, instead of dice.
