1) Miguel sells a house for $275,000. His commission for the sale is $6,875. What percent commission did he earn? (Make sure to write your answer as a percent for example: 6.2%)
Answer: 2.5%
Step-by-step explanation:
Let's use the rule of 3 here.
If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.
Let's put money on one side and percentages on the other.
[tex]\frac{275000}{6875}=\frac{100}{x}[/tex]
Solve for x;
[tex]x=\frac{6875*100}{275000}[/tex]
[tex]x=2.5[/tex]
The Percent commission Miguel earn is 2.5%.
To Find the percent commission Miguel earnedGiven:
Miguel sells a house = $275,000
His commission for the sale =$6,875.
Step 1:
Let's use the rule of 3 here.
If the total price is $275,000 or 100% of the sale,
then $6,875 is X% of the total sale.
Step 2:
Let's put money on one side and percentages on the other
=275000/6875
= 100/x
Solve for x;
x = 6875×100/275000
x = 2.5
Therefore, Percent commission did Miguel earn is 2.5%.

You draw one card from a standard deck of playing cards. If you pick a heart, you win $10. If you pick a face card, which is not a heart, you win $8. If you pick any other card you lose $6. What is the expected value of the game?
Answer:
The expected value of the game is $131
Step-by-step explanation:
54 Cards in a deck including Jokers
52 Cards in a deck not including Jokers
13 Hearts
13 Clubs
13 Spades
13 Diamonds
13 Face Cards
13 / 52 = 25% Chance Of Pulling A Heart
30 / 52 = 57% Chance Of Pulling A Face Card Not A Heart
9 / 52 = 17% Chance of Loosing $6
$130 = Pick A Heart
$81 = Face Card Not a Heart
$130+$81 = $211
30 x 6 = $180
The expected value of the game is $131

1) 4x + 9 = 2x - 6
Subtract 9 from both sides
4x = 2x - 15
Subtract 2x from both sides
2x = -15
Divide both sides by 2:
x = -15/2 or -7.5
2) 2(x - 5) = 5x + 23
Expand the brackets:
2x - 10 = 5x + 23
Subtract 23 from both sides
2x - 33 = 5x
Subtract 2x from both sides
3x = -33
Divide both sides by 3
x = -11
3) 7x + 3 = 2x + 13
Minus 3 from both sides
7x = 2x + 10
Subtract 2x from both sides
5x = 10
Divide both sides by 5
x = 2

The area of the circle is 9π m².
What is the area of the circle?
The area of a circle is the area inside the circle. Hence, the area of the circle = π × R².
Given, the diameter of the circle is(D) = 6 m.
Radius of the circle(R) = D/2 = 6/2 m = 3 m.
Therefore, the area of the circle = π × R² = π × 3² m² = 9π m².

How do you determine the scale factor of a dilation given the side lengths of the pre-image and image? 2. How can dilations help us solve real world problems? *
Answer:
If you're scaling up from a smaller figure to a larger one, plug the lengths into the equation scale factor = larger length over smaller length. If you're scaling down from a larger figure to a smaller one, use the equation scale factor = smaller length over larger length.
Dilatation help us solve real world problems by allowing us to estimate the location that something has to be in or even if an object will fit or not.

The graph of y= √x is transformed as shown in the graph below. Which equation represents the transformed function?
Answer:
1
Step-by-step explanation:
Firstly note that the graph is shifted up 2 units, as it starts at positive 2, when it should start at 0.
That only leaves choices 1 and 2
However, since we know its flipped, we can easily rule out number 2, as number 2 wouldn't be a real number(sqrt of negatives)
That leaves answer choice 1
The correct option is y = -[tex]\sqrt{x}[/tex] +2

You need to create a fenced Off region of Land for cattle to graze. The grazing area must be a total of 500 square feet surrounded by a fence and in the shape of a regular polygon within this grazing area the length of the apothem must be 10 feet long.
Part. 1 find the total perimeter of the grazing area
Part 2. if the cost of the fence is $7.95 per linear foot how much will it cost to place a fence around the entire grazing area?
Part 3 - suppose this grazing area is 1/60 of an industrial grazing area for major industry farm. What is the total cost to build a fence around the entire land of the large scaled farm
Use property of proportions
show all work
Answer:
Part 1: The perimeter of total grazing area is 100 feet.
Part 2: The cost of fencing the entire grazing area is $759.
Part 3: The total cost to build a fence around the entire land of the large scaled farm is $ 45540.
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=

A rectangle room measures 13 feet by 15 feet. The ceiling fan is 8 feet high. Find the total area of all 4 walls that will need to be painted.
448 ft
224 ft
560 ft
336 ft
Answer:
448 ft^2
Step-by-step explanation:
The area of the walls is the perimeter of the room multiplied by the height.
P = 2(L + W)
P = 2(13 ft + 15 ft)
P = 2(28 ft)
P = 56 ft
A = perimeter * height
A = 56 ft * 8 ft
A = 448 ft^2
Do you use the greatest common factor or the least common multiple to add to fractions? In this example what is it? 4/15+5/6
Answer:
The least common multiple, but you can use the greatest common factor, but at the end you have to simplify for it to be correct. 1 3/30
Step-by-step explanation: 4/15+5/6
Change 15 into a 30 by multiplying 2 to both sides.
Change 6 into a 30 by multiplying 5 to both sides.
so the new fractions are 8/30+25/30=33/30
The final fraction is 1 3/30.

Use the combination method to solve for y: 5x + 3y = 12 and -5x + 4y = 16
y= 4
y= 0
y= -10
y= -4
Answer:
y = 4
Step-by-step explanation:
We have,
5x + 3y = 12 ....(1)
and
-5x + 4y = 16 ....(2)
Adding equation (1) and (2),
0 + 7y = 28
or
7y = 28
Dividing both sides by 7,
y = 4
So, the value of y = 4.

Base of triangle = [tex]20cm - ( 4 + 3)cm[/tex]
Base of triangle = [tex]20 - 7 = 13cm[/tex]
Height = 9cm
Area of triangle = (0.5) × base × height
Area of triangle = [tex]0.5 \times 13 \times 9 = 58.5cm^2[/tex]
Area of rectangle = Length × width
Area of rectangle = [tex]20 \times 9 = 180[/tex]
Shaded area = area of rectangle - area of triangle
Shaded area = [tex]180cm^2 - 58.5cm^2[/tex]
Shaded area = [tex]121.5cm^2[/tex]
