Susan works as a Hostess where she makes $8.75 per hour she also babysitting earns $10 per hour last week she made $165 if she works 6 hours more as a Hostess than she did babysitting how many hours did she babysit last week?
Answers
6 hours as babysitter last week
1) Gathering the data
Hostess
8.75h
Babysitting
10h
2) Based on that, we can write out the following equation, considering that Susan worked 6 hours more:
8.75(h+6) +10h= 165 Distribute the factor 8.75
8.75h +52.5 +10h = 165 Combine like terms
18.75h = 165 -52.5 Subtract from both sides 52.5
18.75h = 112.5 Divide both sides by 18.75
h =6
3) Hence, we can conclude that Susan worked as a hostess for 12 hours and as a baby sitter 6 hours last week

Mimstoon started with at most 2 boondins (y). Every day (x), he
bought at most 1/2 more of them.
Write an inequality to model this relationship.
Answers
Step-by-step explanation:
y <= x/2 + 2
the maximum is to have 2 boondins and add 1/2 boondin every day.
but every time Mimstoon did not use the max. possible, the resulting total sum of boodins stays smaller that the maximum, and is therefore a valid data point.
(6, 7) is not in the inequality relationship.
because the max. boondins after 6 days is 2 (from the beginning) and 1/2 every day = 2 + 1/2 × 6 = 2 + 3 = 5.
but the data point shows 7 as y value (which is larger than the allowed max. of 5).
therefore the inequality is false for this data point, and therefore the data point is not in the inequality relationship.

Solve the quadratic equation by completing the square.x^2-14x+46=0First choose the appropriate form and fill in the blanks with the correct numbers. Then solve the equation. If there’s more than one solution, separate them with commas.
Answers
x² - 14x + 46 = 0
subtract 46 from both-side
x² - 14x = -46
Add the square of the half of the co-efficient of x
x² - 14x + (-7)² = -46 + 7²
(x-7)² = -46 + 49
(x-7)² =3
Take the square root of both-side
x-7 = ±√3
x-7= ±1.732
Add 7 to both-side of the equation.
x= 7 ± 1.732
Eithe x= 7 + 1.732 or x= 7 - 1.732
x=8.732 or x=5.268
Therefore x = 8.732 , 5.268

Stores on the verbal Graduate Record Exam (GRE) have a mean of 462 and a standard deviation of 119. Scores on the quantitative GRE have a mean of 584 and a standard deviation of 151. Assuming the scores are normally distributed, what quantitative scores are required for an applicant to score at or above the 90th percentile
Answers
We need Z-score here.
The formula is:
[tex]z=\frac{x-\mu}{\sigma}[/tex]A normal curve (with 90th percentile), looks like the one below:
We need a standard normal table to move further.
When we go to the table, we find that the value 0.90 is not there exactly, however, the values 0.8997 and 0.9015 are there and correspond to Z values of 1.28 and 1.29, respectively
(i.e., 89.97% of the area under the standard normal curve is below 1.28).
The exact Z value holding 90% of the values below it is 1.282.
--------------- Now, we work backwords and find the value of x:
Verbal GRE:
[tex]\begin{gathered} \mu=462 \\ \sigma=119 \\ z=\frac{x-\mu}{\sigma} \\ 1.282=\frac{x-462}{119} \\ x-462=1.282(119) \\ x=614.558 \end{gathered}[/tex]So, a 90th percentile on Verbal GRE is a score above 614.56
Quantitative GRE:
[tex]\begin{gathered} z=\frac{x-\mu}{\sigma} \\ 1.282=\frac{x-584}{151} \\ x=777.582 \end{gathered}[/tex]So, a 90th percentile on Quantitative GRE is a scoer above 777.58

Taking into account the definition of a system of linear equations, a student has 24 dimes and 6 nickels.
System of linear equationsA system of equations is a set of equations in which there are two or more variables, the goal of which is to find all ordered pairs (x, y) that satisfy the equation, where x and y are real numbers.
In other words, a system of linear equations is a set of two or more first degree equations that relate two or more unknowns, in which it is desired to find the value of each unknown so that all the equations of the system are satisfied.
This caseIn this case, a system of linear equations must be proposed taking into account that:
d = number of dimes.n = number of nickels.You know that:
A student has 30 dimes and nickels. The total value is $2.70.The system of equations to be solved is
d + n = 30
0.10d + 0.05n = 2.70
It is decided to solve it using the substitution method. This method consists of isolate one of the variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "d" from the first equation:
d= 30 -n
Replacing the expression in the second equation:
0.10×(30 - n) + 0.05n = 2.70
Solving:
0.10×30 - 0.10n + 0.05n = 2.70
3- 0.10n + 0.05n = 2.70
- 0.10n + 0.05n = 2.70 -3
-0.05n= -0.3
n= (-0.3)÷ (-0.05)
n= 6
Remembering that d=30 -n you get:
d= 30 - 6
d= 24
There are 24 dimes and 6 nickels.

Which relation is a function? 4 15 O -6- 7 C fy 0 -H O O O -2 -4
Answers
The most appropriate choice for functions will be given by -
Third option is correct
Third relation is a function.
What is a function?
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
Here,
For a function a point in the domain has a unique image.
Here values of x axis represents domain and values of y axis represents the range
For the first option,
x = -1 has two images, y = -1 and y = 3
so x = -1 do not have a unique image
So the first relation is not a function
For the second option,
x = 0 has two images, y = -1 and y = 2
so x = 0 do not have a unique image
So the second relation is not a function
For the third option,
Every point of the domain has a unique image
So the third relation is a function
For the fourth option,
x = -2 has two images, y = 1 and y = -2
so x = -2 do not have a unique image
So the fourth relation is not a function
so, Third option is correct

Answers
(a) What was the total amount they ended up paying for the condominium
(including the down payment and monthly payments)?
We need to calculate the total monthly payments, plus the down payment.
[tex]=1396.96\cdot30\cdot12+43000=545905.60[/tex]So, the total amount they ended up paying was $545,905.60
(b) How much interest did they pay on the mortgage?
The interest they pay is: $269,905.60
[tex]=545905.60-276000.00=269905.60[/tex]What is type of angle is it vertical complementary supplementary or none of the above I will reward you greatly if you answer
Answers
In the given figure,
∠a and ∠b are complementary angles.
This is because ∠CXB + ∠a + ∠b = 180° .........(as they form linear pairs)
∠CXB = 90° ..........(given)
Hence,
∠a + ∠b = 90°
What are Complementary Angles?Two angles whose total is 90 degrees are referred to as complementary angles in geometry. To put it another way, complimentary angles are two angles whose sums equal 90 degrees. 60° and 30°, for illustration. By adding up the two angles' measurements, one can determine the complement and supplement of the two angles. Complementary angles are those where the sum of the two angles equals the measurement of a right angle. They are referred to as adjacent complementary angles if they share a vertex and an arm. It is referred to as non-adjacent complementary angles when two complementary angles are NOT contiguous.To learn more about Complementary angles, refer to:

the cost price of 24 articles is the selling price of 15 articles find the gain percentage
Answers
Let cost price of one article be x.
So cost price of 15 articles will be 15*x=15x.
Cost price of 24 articles=selling price of 15 articles.
So selling price of 15 articles= 24*x=24x.
Cost price of 15 articles=15x.
Gain= 24x-15x= 9x.
So gain%= gain/CP ×100.
= 9x/15x *100 .
= 3/5 ×100 .
= 3×20=60%
