a) The number of invitations Sarah can purchase if she does not buy any party favors is: 40
b) The number of party favors Sarah can purchase if she does not buy any invitations is: 10
How to solve Linear Equations?
We are given the linear equation as:
3x + 12y = 120
Where:
x is the number of invitations for the birthday
y is the number of favors for the birthday
a) If she does not buy any party favors, then y = 0 and we have:
3x + 12(0) = 120
3x = 120
x = 40 invitations
b) If she does not buy any invitations, then x = 0 and we have:
3(0) + 12y = 120
12y = 120
y = 10 favors

D 115
The measure of x is 115° from the given parallel lines. Therefore, option D is the correct answer.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Let the interior alternate angle to 65° be y.
Now, y=65° (Alternate interior angles are equal)
Here, y°+x°=180° (Adjacent angles)
65°+x°=180°
x°=115°
Therefore, option D is the correct answer.

Economists predict that Americans will spend $1,180 on Summer Vacation in 2015, this is up 3.4% from 2014. What did Americans spend in 2014?
With the help of percentage increase information, we conclude that, Americans spent approximately $1,141.31 on summer vacation in 2014.
What is percenatge increase?
Percentage increase is a measure of how much a value has increased in comparison to the original value, expressed as a percentage.
To find what Americans spent in 2014, we need to use the percentage increase and the 2015 amount.
Let X be the amount spent in 2014.
We know that the increase from 2014 to 2015 is 3.4%, which can be expressed as:
3.4% = 0.034 (as a decimal)
We also know that the amount spent in 2015 is $1,180.
Using this information, we can set up an equation:
X + 0.034X = 1180
Simplifying the left side:
1.034X = 1180
Dividing both sides by 1.034:
X = 1141.31
So Americans spent approximately $1,141.31 on summer vacation in 2014.

a number has the same digits in its hundreds place and it’s hundrthes place. how many times greater is the value of the digit in the hundreds place than the value of the digit in the hundreds place
In a case whereby a number has the same digits in its hundreds place and it’s hundredths place the number of times that the value is greater in the hundreds place than the value of the digit in the hundreds place is 10,000 times.
How can the value of the digit can be calculated?The question can be interpreted that the particular number has the same digit which is seen in hundreds place hence hundredths place.
we can then represent the digit as '1'.
The value of number's hundreds place can be represented as 100
we can as well represent the number's hundredths place as 0.01
the number of times the value of the hundreds place digit exceeds the value of the hundredths place digit can be expressed as 100/0.01 =(100*100)/1 = 10, 000

If the Federal Reserve decreases the reserve rate from 6% to 4%, how does this affect the amount of money that would result because of fractional-reserve banking from an initial deposit into a bank of $15,000?
A.
It increases the amount by $250,000.
B.
It increases the amount by $125,000.
C.
It decreases the amount by $125,000.
D.
It decreases the amount by $250,000.
The amount of money increases by $125,000 due to the decrease in the reserve rate. The correct answer is B. It increases the amount by $125,000.
When the Federal Reserve decreases the reserve rate, it allows banks to hold a smaller portion of their deposits as reserves and lend out a larger portion. This change stimulates lending and increases the money supply in the economy through the process of fractional-reserve banking.
In this scenario, the initial deposit of $15,000 can be multiplied by the money multiplier, which is the reciprocal of the reserve rate. Initially, with a reserve rate of 6%, the money multiplier is 1/0.06 = 16.67. Therefore, the initial deposit can lead to a maximum increase in the money supply of $15,000 x 16.67 = $250,050.
When the reserve rate is decreased to 4%, the money multiplier becomes 1/0.04 = 25. Therefore, the same initial deposit of $15,000 can now result in a maximum increase in the money supply of $15,000 x 25 = $375,000.
The difference between the two scenarios is $375,000 - $250,050 = $124,950, which is approximately $125,000. Hence, the amount of money increases by $125,000 due to the decrease in the reserve rate.

Which sequence of transformations was applied to the parent tangent function to create the function m(x) = 2tan(3x+4)
The function m(x) = 2tan(3x+4) is obtained by applying a sequence of transformations to the parent tangent function.
To determine the sequence of transformations, let's break down the given function:
1. Inside the tangent function, we have the expression (3x+4). This represents a horizontal compression and translation.
2. The coefficient 3 in front of x causes the function to compress horizontally by a factor of 1/3. This means that the period of the function is shortened to one-third of the parent tangent function's period.
3. The constant term 4 inside the parentheses shifts the function horizontally to the left by 4 units. So, the graph of the function is shifted to the left by 4 units.
4. Outside the tangent function, we have the coefficient 2. This represents a vertical stretch.
5. The coefficient 2 multiplies the output of the tangent function by 2, resulting in a vertical stretch. This means that the graph of the function is stretched vertically by a factor of 2.
In summary, the sequence of transformations applied to the parent tangent function to create the function m(x) = 2tan(3x+4) is a horizontal compression by a factor of 1/3, a horizontal shift to the left by 4 units, and a vertical stretch by a factor of 2.
Example:
Let's consider a point on the parent tangent function, such as (0,0), which lies on the x-axis.
After applying the transformations, the corresponding point on the function m(x) = 2tan(3x+4) would be:
(0,0) -> (0,0) (since there is no vertical shift in this case)
This example helps illustrate the effect of the transformations on the graph of the function.

Step-by-step explanation:
You need to divide 200 and 150 to get you 4/3. Then you will have to _____________________________
You earn $17.50/hr and work 40 hr/wk. Your deductions are FICA (7.65%), federal tax withholding (12.3%), and state tax withholding (6.2%). Your housing and fixed expenses are 30% of your realized income per month. You want to save 5 months' worth in an emergency fund within a year. How much do you need to save per month to fund the emergency fund, and how much discretionary money remains per month?
The amount that you need to save per month to fund the emergency fund would be $ 861. 58.
The discretionary money left per month would be $ 585. 88.
How to find the amount to save ?The gross income for the month :
= 17. 50 x 40 per week x 4 weeks a month
= $ 2, 800
The amount left which is realized funds for the month is:
= Gross income - FICA + Federal tax withholding + State tax withholding
= 2, 800 x ( 1 - 26. 15 %)
= $ 2, 067. 80
Five months of realized income for the emergency fund is:
= 2, 067. 80 x 5
= $ 10, 339
The amount to save per month is:
= 10, 339 / 12
= $ 861. 58
The amount left per month for discretionary expenses ;
= 2, 067. 80 - 861. 58 - 620. 24 rent
