The realtor receives a 5% commission from the sale of a property. For a property sold at $50,000, the realtor's commission would be $2,500, calculated by multiplying the sale price by the commission rate.
To calculate the amount the realtor receives from the sale of a property when they earn a commission of 5%, you can use the following formula:
Commission = Sale Price * Commission Rate
In this case, the sale price of the property is $50,000 and the commission rate is 5%, which is 0.05 when expressed as a decimal.
Thus, the commission the realtor earns is calculated as follows:
Commission = $50,000 * 0.05
Commission = $2,500
Therefore, the realtor would receive $2,500 from the sale of a property that sells for $50,000.
A tree outside Ellie's house casts a 125-foot shadow. At the same time of the day, Ellie casts a 5.5-foot shadow. If Ellie is 4 feet 10 inches tall, how tall is the tree in feet?
Answer:
The tall of the tree is about 109.85 feet
Step-by-step explanation:
* Lets study the situation in the problem
- The tree and its shadow formed a right angle triangle with legs
x the tall of the tree and 125 feet the shadow of the tree
- Ellie and her shadow formed a right triangle with legs 4 feet and
10 inches the tall of Ellie and 5.5 feet the shadow of Ellie
- The two triangles are similar
- There is an equal ratio between the corresponding sides of the
similar triangles
# Ex: If triangles ABC and XYZ are similar
∴ AB/XY = BC/YZ = AC/XZ
* Lets use this rule to solve the problem
∵ The tall of the tree is x
∵ The tall of Ellie is 4 feet and 10 inches
- Lets change the tall of Ellie to feet only
∵ 1 foot = 12 inches
∴ 10 inches = 10/12 = 5/6 foot
∴ The tall of Ellie is 4 feet and 5/6 foot = 4 + 5/6 = 29/6 feet
∵ The shadow of the tree is 125 feet
∵ The shadow of Ellie is 5.5 feet
- By using similarity ratio
∴ Tall of tree/tall of Ellie = shadow of tree/shadow of Ellie
∴ x/(29/6) = 125/5.5 ⇒ using cross multiplication
∴ 5.5(x) = 125(29/6) ⇒ divide both sides by 5.5
∴ x ≅ 109.85 feet
* The tall of the tree is about 109.85 feet
Answer:
The tall tree is about 109.85

The French club is sponsoring a bake sale. If their goal is to raise at least $135, how many pastries must they sell at $3.00 each in order to meet that goal? Write and solve an inequality.
135p ≥ 3.00; p ≥ 45
3.00p ≥ 135; p ≥ 405
3.00p ≥ 135; p ≥ 45
3.00p ≥ 135; p ≥ 132
Answer:
3.00p ≥ 135; p ≥ 45
Step-by-step explanation:
You sell each for $3 so 3(pastries sold or p).
You want to make AT LEAST 135 (you could make more but not less.)
so 3.00p ≥ 135.
To solve: divide 135 by 3.
p ≥ 45
Answer: [tex]3p\geq135[/tex] ; [tex]p\geq45[/tex]
Step-by-step explanation:
Given : The French club is sponsoring a bake sale. If their goal is to raise at least $135 (greater than of equal to $135).
Let p be the number of pastries they sell.
If they sell at $3.00 each in order to meet that goal, then the total price of p pastries will be : 3p
Then, the inequality for the given statement will become:-
[tex]3p\geq135[/tex]
Divide both sides by 3 , we get
[tex]p\geq45[/tex]
Hence, they must sell 45 or more pastries to raise at least $135.

On in-line skates, Bradley skates 4 miles in 20 minutes. At this speed, how long would it take him to skate the entire length of a 12-mile bike path?
Answer:
1 hour (60 minutes)
Step-by-step explanation:
If his speed remains the same, that means that this is a linear relationship. y increases at the same rate as x increases. Direct variation and all of that. Because this is a linear relationship, it can be solved using proportions. Set up the given info in a ratio with miles on the top and minutes on the bottom:
[tex]\frac{miles}{minutes}:\frac{4}{20}[/tex]
Now we want to know how long (unknown number of minutes) it will take him to go 12 miles. Keep miles with miles and minutes with minutes:
[tex]\frac{miles}{minutes}:\frac{4}{20}[/tex]=[tex]\frac{12}{x}[/tex]
We can cross multiply now to get 4x = 12(20) and 4x = 240. That means that x=60. It will take him 60 minutes (1 hour) to go 12 miles.

If 21 more than 3 times a number is -15 , what is the number?
A: 2
B: -12
C: -2
D: 12
Let X = the number.
You have 21 more than 3 times the number which is:
3x +21 = -15
Subtract 21 from both sides:
3x = -36
Divide both sides by 3:
x = -36 /3
x = -12
The answer is B.
Answer:
-13
Explanation:
Rewrite Equation:
(3 · x) + 21 = -15
Subtract 21 From Both Sides:

If the endpoints of the diameter of a circle are (−6, 6) and (6, −2), what is the standard form equation of the circle? A) x2 + (y + 2)2 = 36 B) x2 + (y + 2)2 = 52 C) x2 + (y − 2)2 = 36 D) x2 + (y − 2)2 = 52
Answer:
D) x² + (y − 2)² = 52
Step-by-step explanation:
The center of the circle is the midpoint of the diameter, so is the average of the end points:
(h, k) = ((-6, 6) +(6, -2))/2 = (0, 4)/2 = (0, 2)
Then the distance between the center and an end point is the radius. It is found using the distance formula:
r = √((x2 -x1)² +(y2 -y1)²) = √((-6 -0)² +(6 -2)²) = √(36 +16) = √52
Putting these values into the standard form equation for a circle ...
(x -h)² +(y -k)² = r²
gives ...
(x -0)² +(y -2)² = (√52)²
x² +(y -2)² = 52 . . . . . matches choice D
Instead of the three dots, write a digit to make the fraction reducible. (Find all possible cases.) 12.../23...
Answer:
{0, 1, 2, 4, 5, 6, 8}
Step-by-step explanation:
120/230 = 12/23
121/231 = 11/21
122/232 = 61/116
123/233 -- not reducible
124/234 = 62/117
125/235 = 25/47
126/236 = 63/118
127/237 -- not reducible
128/238 = 64/119
129/239 -- not reducible
___
All even digits will make the fraction reducible, as will the digit 5. Then the digits we're not sure of are 1, 3, 7, 9. Appending 1 to the given numbers makes them divisible by 11, so that digit is included in our list.
Ending digits 3, 7, 9 result in fractions that are not reducible. (Numbers 127, 233, and 239 are prime numbers.)
