Given:
A table is on sale for 38% off, The sale price of table is $527.00.
To find:
The regular price of the table.
Step by step solution:
To solve this problem, we need to use the basic formula of sales price and discount:
Sale price = $527.00
Discount percentage= 38%
[tex]\begin{gathered} \text{sale price = cost price - discount }\times\text{ \lparen cost price \rparen} \\ \\ 527=cp-\frac{38}{100}(cp) \\ \\ 527=\frac{62}{100}(cp) \\ \\ cp=\frac{52,700}{62} \\ \\ cp=850 \end{gathered}[/tex]From here we can say that the Cost-price / Regular price of the table is equal to $850.
Find the APR (rounded to the nearest tenth of a percent) for the loan. Purchase a living room set for $3,600 at 8 % add- on interest for 3 years.
The annual percentage rate (APR) for the loan of $3,600 at 8% add-on interest for 3 years is 15.6%.
What is the annual percentage rate?The annual percentage rate is the nominal or effective interest rate charged on a loan for a year, unlike the Monthly Percentage Rate (MPR), which is a monthly rate.
The annual percentage rate can be calculated by using the formula:
APR = 2Nr/N + 1
N = number of payments
r = the add-on interest rate
N = 3 years = 36 months (12 x 3)
r = 8% or 0.08 (8/100)
APR = (2 x 36 x 0.08)/(36 + 1)
= 5.76/37
= 0.15.57
= 15.57%
= 15.6%
Thus, with an 8% interest rate for 3 years, the APR is 15.6%.

Find the equation of the line whose slope is 1/6 passing through the point (-9, 3)
The equation of the line whose slope is 1/6 passing through the point (-9, 3) is -x - 6y - 27 = 0
What is slope formula ?To determine a line's inclination or steepness, use the slope formula. By calculating the ratio of the change in the y-axis to the change in the x-axis, it may be used to calculate the slope of any line. A line's slope is determined by how its "y" coordinate changes in relation to how its "x" coordinate changes.
Given slope of equation m =[tex]\frac{1}{6}[/tex]
A point on line (x₁,y₁) = (-9,3)
(y-y₁)= m (x-x₁)
(y-3) = [tex]\frac{1}{6}[/tex] ( x − (-9))
y-3= [tex]\frac{1}{6}[/tex] (x+9)

y=(x-5)^2 quadratic function and state the functions domain and graph
The graph y= f(x) is shown. Translate it to get the graph of y = f(x-2)
The translation of two units right of the graph of y = x is graphed at the end of the answer.
TranslationTranslation is a transformation to the graph of a function or of a figure that keeps everything such as orientation and inclination stable, changing only the position of the graph.
The translations are movements to left, right, up or down, and each movement is represented as follows:
Left a units: f(x + a).Right a units: f(x - a).Up a units: f(x) + a.Down a units: f(x) - a.In this problem, the definition of the translation is given as follows:
y = f(x - 2).
Hence a = 2, and the function is shifted right 2 units.
Considering function y = x, the translated function is:
y = f(x - 2) = x - 2.
(each instance of x in the function is replaced by x - 2).
The graph of the two functions is shown at the end of the answer, which x - 2 being a shift right of 2 units of f(x).
Missing InformationThe function is not given, hence we suppose that it is of y = x.

Consider that the Alternate Exterior Angles are always equal for a transversal passing through two parallel lines.
The given diagram depicts two incline parallel lines and the vertical line acts as a transversal to them.
Now, angle 1 and angle 8 are alternate exterior angles so they must be equal,
[tex]\begin{gathered} m\angle1=m\angle8 \\ x+74=2x-1 \\ 2x-x=74+1 \\ x=75 \end{gathered}[/tex]So the measure of the angles is given by,

according to City high school's alumni records 375 students graduated in college in 2001 are these graduates 176 were female 100 and 47 of whom were accepted into college of the male graduate 100 were accepted to college.A) what is the probability that a 2001 graduate of City high School was accepted into collegeB) what is the probability that 2001 graduate of City high School was not a female C)what is the probability that a 2001 graduate of City high School was accepted into college or maleD) what is the probability of being a female given you were accepted into college.
We are asked to determine probabilities from a population of high school graduates. Let's remember that probability is defined as the quotient of desired events and the number of total events.
a) what is the probability that a 2001 graduate of City High School was accepted into college
To determine the probability we need to find the quotient of the number of students that were accepted into college and the total number of students. The total number of students accepted into college is 145 female plus 100 males, therefore, the probability is:
[tex]P(a)=\frac{145+100}{375}=\frac{245}{375}=0.653[/tex]Therefore, the probability is 65.3%.
b)what is the probability that 2001 graduate of City high School was not a female
To do this we will use the fact that the sum of the probabilities that a student is a female plus the probability that the student is not a female must be equal to 1.
[tex]P(\text{female)}+P(\text{not female)=1}[/tex]Therefore, solving for the probability that the student is not a female we get:
[tex]P(\text{not female)=1-P(female)}[/tex]The probability that the student is female is the quotient between the number of female students and the total number of students, therefore:
[tex]\begin{gathered} P(\text{not female)=1-}\frac{176}{375} \\ \\ P(\text{not female)=1-0.461} \\ P(\text{not female)=0.539} \end{gathered}[/tex]Therefore, the probability that the student is not a female is 53.9%.
c) what is the probability that a 2001 graduate of City high School was accepted into college or male
To determine this probability we need to have into account that the probability of event A or event B happening is the sum of both probabilities minus the probability of both events happening at the same time, therefore:
[tex]P(\text{accepted or male)=P(accepted)+P(male)}-P(\text{accepted and male)}[/tex]Replacing the probabilities we get:
[tex]P(\text{accepted or male)=}0.653+\frac{375-176}{375}-\frac{100}{375}[/tex]Solving the operations:
[tex]\begin{gathered} P(\text{accepted or male)=0.653+0.53-0.267} \\ P(\text{accepted or male)=0.916} \end{gathered}[/tex]Therefore, the probability that a student is accepted or male is 91.6%
d) what is the probability of being a female given you were accepted into college.
The probability of event A given event B is given by the following formula:
[tex]P(A\parallel B)=\frac{P(AandB)}{P(B)}[/tex]In this case, we have:
[tex]P(female\parallel accepted)=\frac{P(\text{female and accepted)}}{P(accepted)}[/tex]Replacing the probabilities:
[tex]\begin{gathered} P(female\parallel accepted)=\frac{\frac{147}{375}}{0.653} \\ \\ P(female\parallel accepted)=\frac{0.392}{0.653} \\ \\ P(\text{female}\parallel accepted)=0.6 \end{gathered}[/tex]Therefore, the probability is 60%.

there are about 6*10^24 molecules in a litre of water. it is estimated that a person drinks about 2.2 *10^3 litres of water a year. how many molecules of water does a person drink in a year?
Based on the concept of multiplication, the amount of molecules consumption of water does a person drink in a year is 1.32 x 10²⁸.
Molecules:
A molecules is the group of two or more atoms linked together by sharing electrons in a chemical bond
Given,
There are about 6 x 10²⁴ molecules in a liter of water. it is estimated that a person drinks about 2.2 x 10³ liters of water a year.
Here we have to find the amount of molecules consumption of water does a person drink in a year.
To find the total amount of molecules consumption for the year we have to use the following formula,
Total molecules consumption per year = amount of water x molecules.
Here we know the values of the following,
Water consumption per year = 2.2 x 10³ liters
Molecules of one liter water = 6 x 10²⁴
Apply the values on the formula, then we get,
=> total molecules consumption = (2.2 x 10³) x (6 x 10²⁴)
=> (2.2 x 6) x (10³ x 10²⁴)
=> 13.2 x 10³⁺²⁴
=> 13.2 x ²⁷
It can be further simplified as,
=> 1.32 x 10²⁸
Therefore, the amount of molecules consumption of water does a person drink in a year is 1.32 x 10²⁸.

To indirectly measure the distance across a river, Kiran stands on one side of the river and uses sight-lines to a landmark on the opposite bank. Kiran draws the diagram below to show the lengths and angles that he measured. Find PR, the distance across the river. Round your answer to the nearest foot.
Okay, here we have this:
Considering the provided information and figure, we are going to calculate the requested measure, so we obtain the following:
We can see that the two triangles are similar because they have the same angles, so from this we have:
PR/RE=PO/OC
PR/195=(PR+160)/305
PR*305=(PR+160)195
305PR=195PR+31200
305PR-195PR=31200
110PR=31200
PR=31200/110
PR=3120/11
PR≈294 ft
Finally we obtain that PR, the distance across the river is approximately 294 ft.
