Samuel paid $720 for a new music system. The list price for the music system was $800. What was his rate of discount?
Samuel received a 10% discount on the music system, calculated by finding the difference between the list price ($800) and the sale price ($720), then dividing that by the list price and multiplying by 100.
Explanation:The question at hand is about calculating the rate of discount Samuel received on his new music system. Initially, the list price of the music system was $800, but Samuel paid $720 for it. To find the rate of discount, we first need to determine the discount amount which is the difference between the list price and the sale price.
List Price = $800Sale Price = $720Discount Amount = List Price - Sale Price = $800 - $720 = $80Next, to find the rate of discount, we use the formula:
Rate of Discount = (Discount Amount / List Price) × 100
Substituting the values we have:
Rate of Discount = ($80 / $800) × 100 = 10%
Therefore, Samuel received a 10% discount on the music system.

Which number produces an irrational number when added to 0.4
To find an irrational number when added to 0.4, you need to add an irrational number. One example is adding the square root of 2 to 0.4.
To find a number that produces an irrational number when added to 0.4, let's consider a rational number like 0.6.
Irrational numbers are infinite in nature and cannot be represented accurately as a finite decimal or fraction. They exist along with rational numbers, forming the set of real numbers on the number line.
0.4 + 0.6 = 1, which is rational.Rational + Irrational = Irrational, so to get an irrational number, you need to add an irrational number.One example of an irrational number you can add to 0.4 to get irrational is √2 - 0.4, where √2 is irrational.which choice shows three lengths cannot be the lengths of the three sides of a triangle

Answer:
the answer is b
Step-by-step explanation:
the sum of the 2 smallest sides must be greater than the 3rd side in order for it to be a triangle
but in B, the sum of the 2 smallest sides is less than the 3rd side

Darrin lives in Washington, D.C., which has a sales tax of 6%. He just bought a video camera whose full price was $620, but after sending in a rebate form, he later received a check in the mail for $95. What was the total amount that Darrin ended up paying after receiving the rebate? A.$562.20 B.$556.50 C.$525.00 D.$657.20
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
Cost of video camera = $620
Rate of sales tax = 6%
Amount of sales tax is given by
[tex]\dfrac{6}{100}\times 620\\\\=\$37.2[/tex]
Total amount after sales tax is given by
[tex]\$620+\$37.2\\\\=\$657.20[/tex]
Amount of rebate = $95
So, final amount that Darrin ended up paying after receiving the rebate is given by
[tex]\$657.20-\$95\\\\=\$562.20[/tex]
Hence, option 'A' is correct.

the slope of a line is negative 1 / 5 and the y-intercept is 5 what is the equation of the line written in general form
Answer;
= x + 5y -25 =0
Explanation;
Thee equation of a line in general form is ;
Ax + By + C = 0
Where A, B and C are integers.
The equation of a line in slope-intercept form is
y = mx + b ; where m is the slope and b is the y-intercept
In this case; m = -1/5 and b =5
thus; y = -1/5 x + 5 (the slope-intercept form)
y = -1/5 x + 5
Multiplying all terms by 5
5 y = -x + 25
= x + 5 y - 25 = 0 (in general form)

Which rule can be used to describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3?
"Which rule ..." suggests you have some rules to choose from to describe the growth. Since you refer to "each interval from x=-1 to x=3", we assume your rule is concerned with more than one interval. With no further clues as to what you may be looking for, we can compute the factor by which the function grows from x=-1 to x=3.
The growth factor over that interval is the ratio of final value to initial value:
.. (12^3)/(12^-1) = 12^(3 -(-1)) = 12^4 = 20,736
Answer:
The rule "multiply by 12" describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3.
Step-by-step explanation:
The given function is
[tex]y=12^x[/tex]
The initial value is 1 and the growth factor is 12.
It is an exponential function.
At x=-1
[tex]y=12^{-1}=\frac{1}{12}[/tex]
At x=0
[tex]y=12^{0}=12^{-1}\times 12=1[/tex]
At x=1
[tex]y=12^{1}=1 \times 12=12[/tex]
At x=2
[tex]y=12^{2}=12 \times 12=144[/tex]
At x=3
[tex]y=12^{3}=144 \times 12=1728[/tex]
Therefore the rule "multiply by 12" describe the growth of the y-values of the function y=12^x over each interval from x=-1 to x=3.

Is it possible for two integers to have no common factors
Final answer:
Two integers can have no common factors, making them coprime or relatively prime.
Explanation:
Yes, it is possible for two integers to have no common factors. When two integers have no common factors, they are considered relatively prime or coprime. For example, 15 and 28 are coprime because the only positive integer that divides both numbers is 1.
Which image that would portray the rotation of the given preimage and the rotation arrow.
Pre-image (1st picture shown):
Image (the following 4 pictures are the options):
Answer:
First figure as shown below is the correct option.
Step-by-step explanation:
We are given that,
The pre-image is rotated in the direction of the arrow to form an image.
It is required to find the image formed.
Since, the arrow is rotating counter-clockwise, we get that,
The star in the pre-image will rotate upwards towards the left.
So, according to the options, we have,
The first image where the star is at the highest height will be the image after rotating the pre-image.
Hence, the first figure as shown below is the correct option.

Claire created a pie chart to show how she spent her time on Monday She spent 8 hours at school, 4 hours playing basketball, 2 hours doing homework, 8 hours sleeping, and 2 hours doing chores. Which statements describe how the pie chart will look? Check all that apply
The pie chart showing Claire's daily activities will have five sections representing school, basketball, homework, sleeping, and chores. Each section will portray the fraction of 24 hours that she spends on that activity. For example, School and Sleeping will both occupy 1/3 of the pie chart each.
Explanation:The subject in question is related to pie charts in Mathematics, specifically fractions and percentages. Claire has a total of 24 hours in the day and her activities are school for 8 hours, basketball for 4 hours, homework for 2 hours, sleep for 8 hours, and chores for 2 hours. In the pie chart, her spent time in a day can be shown as fractions of the total time, 24 hours.
For instance, Claire spent 8/24 or 1/3 of her time at school; the pie chart will show a section occupying 1/3 of the circle representing this. Similarly, she spent 4/24 or 1/6 of her time playing basketball, 2/24 or 1/12 of her time doing homework, 8/24 or 1/3 of her time sleeping, and 2/24 or 1/12 of her time doing chores. Each of these fractions will be a section on the pie chart. Hence, the chart will have five different sections, each representing a different activity.
