Answer:
25%
Step-by-step explanation:
30/40 = 0.75 = 75% paid
100-75 = 25% discount
Answer:
[tex]25\%[/tex]
Step-by-step explanation:
To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;
[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]
Substitute in the given values;
[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]
Solve;
[tex]\frac{10}{40}=\frac{percent}{100}[/tex]
Simplify,
[tex]\frac{1}{4}=\frac{percent}{100}[/tex]
Cross products,
[tex]100 = 4(percent)[/tex]
Inverse operations,
[tex]100=4(percent)\\/4\\\\25 = percent[/tex]
I need help on 7 and 8!!!!!Find the diameter of each circle. Use a calculator’s value of Pi. Round your answer to the nearest tenth.
Answer:
37.6 in
48.2 yd
Step-by-step explanation:
The are of a circle is given as :
Area = pi(d²) /4
Area = 1110.4in²
1110.4 = 3. 14 * d² / 4
1110.4 * 4 = 3.14 * d²
4441.6 = 3.14d²
d² = 4441.6 /3.14
d² = 1413.8051
d = 37.600
d = 37.6
8.)
Area, A = 1824.7yd²
1824.7 = 3. 14 * d² / 4
1824.7 * 4 = 3.14d²
7298.8 = 3.14d²
d² = 7298.8 / 3.14
d² = 2323.2801
d = sqrt(2323.2801)
d = 48.200
Hence, diameter = 48.2 yd

Which statement is true about the data sets of two sets of quiz scores?
Sample A: 5, 5, 5, 5, 5 Sample B: 2, 2, 2, 2, 17
Select one:
Samples A and B have the same mean, but Sample A has a smaller median than Sample B.
Samples A and B have the same median, but Sample A has a larger mean than Sample B.
Samples A and B have the same median, but Sample A has a smaller mean than Sample B.
Samples A and B have the same mean, but Sample A has a larger median than Sample B.
Answer: Samples A and B have the same mean, but Sample A has a larger median then Sample B.
Step-by-step explanation:
The median is the middle number in the sequence.
To find the median, place the numbers in order. Then take away, or cross out, one number from each side. Keep going until you are down to one or two numbers. If there is only one number left, that’s your median. If two, add the numbers together and divide by 2.
The mean is the average. To get the mean you add up all the values and subtract that sum by how many numbers there are in the sequence.
Option D is correct for the given conditions, Samples A and B have the same mean, but Sample A has a larger median than Sample B.
What are measures of central tendency?The descriptive summary of a data set is known as the central tendency in statistics. It reflects the center of the data distribution through the use of a single number from the dataset. Additionally, it only provides a summary of the dataset rather than information on specific data within the dataset. In general, several statistical metrics can be used to determine a dataset's central tendency.
Given the data sets of two sets of quiz scores,
Sample A = 5, 5, 5, 5, 5
sample B = 2, 2, 2, 2, 17
mean is the average of total samples,
mean of sample A = (5 + 5+ 5 + 5 + 5 )/5
mean of sample A = 5
Mean of sample B = (2 + 2 + 2+ 2 + 17)/5
mean of sample B = 5
since the mean of both sample are same,
median is the central digit of sets
median of A is 5 and the median of B is 2,
so the median of sample A is larger than sample B.
Hence option D is correct.

Slope intercept form of 4x+4y=-32
Answer:
y = - x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 4y = - 32 ( subtract 4x from both sides )
4y = - 4x - 32 ( divide all terms by 4 )
y = - x - 8 ← in slope- intercept form
Answer:
x+y=-8
Step-by-step explanation:
-32=4x+4y
-4y=4x+32
y=(4x+32)/-4
y=-x-8
x+y=-8
Now comparing to slope intercept form
y=mx+c,we get
slope =1
y intercept =1
y=-8

Mike pays $8,000 in property taxes, but receives a 28% tax deduction for it. What is Mike’s net expense for property taxes
Answer:
$5760
Step-by-step explanation:
Given data
Principal= $8,000
Tax= 28%
Let us compute 28% tax deduction
=28/100*8000
=0.28*8,000
=$2240
Hence the net expenses is
=8000 -2240
=$5760
Given: y= 2x + 1 and - 4x + y = 9,
solve the system by substitution
Answer:
x=-4 y=-7
Step-by-step explanation:
-4x+y=9 get y alone
add 4x both sides
y=4x+9
insert into y=2x+1
2x+1=4x+9
subtract 1 both sides
2x=4x+8
subtract 4x both sides
-2x=8
divide by -2
x=-4
y=2x+1
y=2(-4)+1
y=-8+1
y=-7
check
-4(-4)+(-7)=9
-16+(-7)=9
9=9
x=-4
y=-7

What is the slope of any line?A line in the form of ax + by + d = 0 will be a linear equation and if we convert it into the form of y = mx + c where m will be the slope of that equation.
If two lines are perpendicular to each other then the product of their slope of them will be (-1).
⇒ m₁ ₓ m₂ = -1
The slope of line 2x + 3y = 10 will be -2/3
To be any line perpendicular whose slope m with the 2x + 3y = 10
⇒ -2/3 × m = -1
⇒ m = 3/2 so the slope of that line should be 3/2
Hence, line y=3/2x-10 will be perpendicular to the 2x + 3y = 10.

A percentage is a way to describe a part of a whole. 20 is 80% of 25.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the number be x. Therefore, we can write,
80% of x = 20
0.80 × x = 20
x = 20/0.8
x = 25
Hence, 20 is 80% of 25.

x + 15x + 24 = -21 - 4x
Answer:
x= -9/4
Step-by-step explanation:
1) Isolate X
2) This will give you x+15x+4x=-21-24
(moving terms to another side will make it opposite, in this case positive 24 moving to the right will become negative 24)
3) Add the like terms
x+15x+4x = 20x
-21-24= -45
this will give you 20x=-45
4)Find the value of X by moving the 20 multiplier to the other side (this will become the opposite, division of 20)
x= -45/20
5) Simplify your answer

How to calculate the third party discounts?Third party discount is the multiplication result of the maturity value of the original rate to the rate of interest and time period.
Thus, we get:
Third party discount = Maturity value × R × T (R in decimal form).
We have been given that a shirt that normally costs $19.99 is on sale for 15% off. we are asked to find the discount on the shirt.
Therefore,
19.99 x 15/100
19.99 x 0.15 = 2.99
Then subtract from the total amount;
19.99 - 2.99 = 16.99
Therefore, the shirt cost after the discount will be $16.99. thus option C is correct.
