Change the denominator of the fraction
7/y-b to b-y
Answer:
[tex]\frac{- 7}{b - y}[/tex]
Step-by-step explanation:
Algebraic manipulation (i.e. a process involving rearranging or rewriting variables and, multiplication or division, to achieve an algebraic expression in a desired form) will be applied:
The expression in the denominator (y - b) will be algebraically manipulated by being multiplied by negative one:
[tex](y - b)[/tex]×[tex](-1)[/tex]
The parenthesis will be expanded by applying the Distributive Law. The derived variables will be rearranged to achieve the desired form of the algebraic expression:
[tex][(-1)(y)] - [(-1)(b)][/tex] = [tex]-y - (-b)[/tex]
= [tex]-y + b[/tex]
= [tex]b - y[/tex] (Desired form achieved)
∴The multiple factor of negative one will also need to be multiplied with the numerator of the fraction for balance. This is because the negative one (that is being multiplied with the denominator) was NOT present originally:
[tex](-1)[/tex]×[tex](7)[/tex] = [tex]-7[/tex]
∴The desired form of the fraction is:
[tex]\frac{-7}{b - y}[/tex]
The fraction 7/(y - b) after changing the denominator (b - y) becomes - 7/(b - y).
Fraction is a comparison between two mathematical quantities or numbers in general.
The number which is being compared is called Numerator and the with whom it is compared is called Denominator.
In mathematical words, if a fraction is look like A/B where A and B are two numbers then A is called Numerator and B is called Denominator.
Here given the fraction is, 7/(y - b)
So here numerator = 7 and denominator = y - b
We have to change the denominator that is (y - b) with (b - y).
Rearranging the fraction we get,
7/(y - b) = 7/[- (b - y)] = - 7/(b - y).

Ramiro got his first job in 2020. In that year, Social Security tax was 6.2% of income up to
$137,700. Medicare tax was 1.45%. If Ramiro earned $73,210 in 2020, how much did he pay for
Social Security and Medicare taxes?
In 2020, Ramiro paid $4,537.22 for Social Security tax and $1,061.70 for Medicare tax
What is Percentage?
Percentage is a way of expressing a number as a fraction of 100. It represents a proportion or rate out of 100, and is often used to compare values or to express a change or growth.
Solution:
To find how much Ramiro paid for Social Security and Medicare taxes in 2020, we can follow these steps:
1. Calculate the amount of Ramiro's income that is subject to Social Security tax. In 2020, Social Security tax was only applied to the first $137,700 of income. Since Ramiro's income of $73,210 is less than $137,700, all of his income is subject to Social Security tax.
2. Calculate the amount of Social Security tax that Ramiro paid. Since Social Security tax was 6.2% of income in 2020, Ramiro paid:
3. Social Security tax = 0.062 x $73,210 = $4,537.22
1. Calculate the amount of Medicare tax that Ramiro paid. Medicare tax was 1.45% of all income, with no income limit. Therefore, Ramiro paid:
2. Medicare tax = 0.0145 x $73,210 = $1,061.70
Therefore, in 2020, Ramiro paid $4,537.22 for Social Security tax and $1,061.70 for Medicare tax, for a total of $5,598.92 in Social Security and Medicare taxes.

the probability of getting a head on the next flip is estimated to be 0.81. The probability of getting two heads in a row would be the square of this probability, or 0.81 * 0.81 = 0.6561.
The probability of getting a head on any single flip of a fair coin is 1/2. However, based on the results of the previous 100 tosses, we can estimate the probability of getting a head on the next flip as the ratio of heads to total tosses, which is 81/100 or 0.81. So, the probability of getting a head on the next flip is estimated to be 0.81. The probability of getting two heads in a row would be the square of this probability, or 0.81 * 0.81 = 0.6561. The mathematical concept of probability quantifies the possibility that an event will occur. A number between 0 and 1, where 0 denotes an improbable event and 1 denotes a certain event, is used to express it. Events with intermediate probabilities (between 0 and 1) indicate a likelihood of occurrence that is between impossible and certain. The sum of the probabilities of all possible outcomes of an event must equal 1.

The last rectangle is 16 by 4. (8-4 =4)
This is because 6+5+5=16.
Then you add up the area to get the whole figure.
The two smaller rectangles are 20 each or 40 altogether and the larger rectangle is 64.
When you add it up you get an area of [tex]104 ft^2[/tex]
PLEASE!!! Someone, please help test tomorrow!! Just explain how to get this please!

suppose you want to fence a rectangular soccer field site that has its length equal to three times its width. the fencing for the east and west sides costs $6 per foot, and the fencing for the north and south sides costs only $3 per foot. find the total cost of the fencing as a function of the length of a side x (feet).
The total cost of the fencing can be expressed as a function of x: C(x) = $24x.
Let's assume that the width of the soccer field is x feet. Then the length of the soccer field is 3x feet.
The east and west sides have a combined length of 3x feet, and the cost per foot of fencing is $6, so the total cost for the east and west sides is $6 * 3x = $18x.
The north and south sides have a combined length of 2x feet, and the cost per foot of fencing is $3, so the total cost for the north and south sides is $3 * 2x = $6x.
The total cost of the fencing is the sum of the cost of the east and west sides and the north and south sides: $18x + $6x = $24x.
So, the total cost of the fencing can be expressed as a function of x: C(x) = $24x.

2. ABCD is a parallelogram and AE and CF are the altitudes (Fig. 9.29). Given AB = 12 cm, AD = 6 cm and AE = 7.5 cm. Find ar(ABCD) and the length of CF.
The length of CF is given as 45 cm
How to solve for the length of CFSince AE is the altitude of the parallelogram ABCD, it is perpendicular to the base DC. Similarly, CF is the altitude of the triangle ACD, and it is perpendicular to the base AD.
Let's use the properties of parallelograms and triangles to solve for the area and length of CF.
Since ABCD is a parallelogram, we know that opposite sides are parallel and equal in length. Therefore, BC = AD = 6 cm.
To find the area of the parallelogram, we can use the formula:
ar(ABCD) = base × height
We can choose any base and height, as long as they form a right angle. Since we know AE is the altitude of the parallelogram, we can use it as the height. Let's choose base AB, which is perpendicular to AE. Therefore,
ar(ABCD) = AB × AE = 12 cm × 7.5 cm = 90 cm²
So, the area of the parallelogram ABCD is 90 cm².
Now, let's find the length of CF. Since CF is the altitude of the triangle ACD, we can use the formula for the area of a triangle:
ar(ACD) = 1/2 × base × height
where the base is AD and the height is CF. We know the area of the triangle ACD is half the area of the parallelogram ABCD, which is 90/2 = 45 cm². Therefore,
45 cm² = 1/2 × 6 cm × CF
Simplifying this equation, we get:
CF = (45 cm² × 2) / (6 cm) = 15 cm
So, the length of CF is 15 cm.
