A real estate agent received 1.5% commission for a house that sold for $250,000. How much was the agent's commission?
a. $3,750
b. $375
c. $37,500
d. $125,000
Answers
Answer:
The answer is B.
Step-by-step explanation:
The answer would be B because dividing 250,000 would get you 25,000 which would be 10% of the total cost. Dividing by 10 again would get you 2500 which would be 1% of the total cost. Divide 2500 by 2 and you'll get 1250. 1250 + 2500 would be 1.5% of the total cost.

Fatima found a $129 prom dress at the department store. She also had to pay a 6.5% sales tax. What was the total cost of the prom dress?
Answers
Answer
137.385
Step-by-step explanation:
What is 6.5% of 129?
First, you have to change 6.5% to a decimal which is 0.065.
Then, you have to multiply 0.065 times 129 which gives you 8.385.
Finally, you have to add that amount to 129 which gives you $137.385, and that is the total cost of the prom dress

whats 2/3 divided by 1/4
Answers
Answer:
8/3 or 2 2/3
Step-by-step explanation:
2/3 ÷ 1/4
The numbers in 2/3 divided by 1/4 are labeled below:
2 = dividend numerator
3 = dividend denominator
1 = divisor numerator
4 = divisor denominator
To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.
Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:
2*4/3*1=8/3
Thus, the answer to 2/3 divided by 1/4 in fraction form is:
8/3
Here we will show you how to calculate 2/3 divided by 1/4. We will give you the answer in fraction form and in decimal form.
Here is 2/3 divided by 1/4 displayed mathematically in colors:
2/3 ÷ 1/4
The numbers in 2/3 divided by 1/4 are labeled below:
2 = dividend numerator
3 = dividend denominator
1 = divisor numerator
4 = divisor denominator
To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.
Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:
2 x 4/3 x 1= 8/3
Thus, the answer to 2/3 divided by 1/4 in fraction form is:
8/3
To make the answer to 2/3 divided by 1/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
8/3 = 2.6667
The answer is rounded to the nearest four decimal points if necessary.
8/3 is an improper fraction and should be written as 2 2/3.

What are the midline, amplitude, and period of the graphed sine function?
The midline of the function is at y= ________.
The amplitude of the function is __________.
The period of the function is _________ pi.
Answers
The midline, amplitude and period respectively of the given sine graph are; x = 1; 2; π
Midline, Amplitude and Period
The midline of this trigonometric graph is defined as the horizontal line that divides the maximum and minimum point distance into two equal parts. In this case, the midline is x = 1
The amplitude of a graphed function is usually the peak of the wave of that graph. In this case, we see that the peak of the graph is at y = 4. Thus, Amplitude = 4
Period is the difference between two consecutive maximum or minimum points. In this graph, the period is π
