The price of a pair of jeans was $31, but due to an increase the price went up to 129% of what it was originally. Which is the best estimate of the current price of the pair of jeans?
Answers
3999 ÷ 100 = 39.99
The best estimate of the current price of the jeans is $39.99.
Answer:
the best estimate of the current price is $39.99
Step-by-step explanation:
Hello, I think I can help you with this,
You can solve this by using a rule of three
Step one
if
$31 ⇔100%
x? ⇔129%
the relation is
[tex]\frac{31}{100}=\frac{x}{129}}\\now, solve\ for\ x\\x=\frac{129*31}{100} \\x=\frac{3999}{100}\\ x=39.99\\[/tex]
the current price is $39.99

solve the equation for y.
xy-7y=49
Answers
First, we factor out the common term for "y"
y(x - 7) = 49
Now, divide both sides by x - 7.
y = 49/x-7 <====
The solution of the given equation xy-7y=49 for y is y = 49/(x-7) for all values of x not equal to 7.
To solve the equation xy-7y=49 for y, first we can factor out y from the left side of the equation which gives us y(x-7)=49.
Then we can isolate y by dividing both sides of the equation by (x-7).
This gives us y = 49/(x-7).
This solution assumes that x is not equal to 7 because division by zero is undefined.
Hence, the solution is y = 49/(x-7) for x ≠ 7.

Thinking about the different types of numbers you learned in this unit, how would you help someone remember the differences between rational and irrational numbers?
Answers
The Difference between Rational numbers and Irrational numbers are given as follows
Rational numbers = A number of the form [tex]\dfrac{p}{q}[/tex] when [tex]q\neq 0[/tex] is called as a Rational number
Example = Any fraction of the form p/q such as 2/3 , -3/11 and 5/12
Irrational number = A number that can not be expressed in the form of [tex]\dfrac{p}{q}[/tex] or nor it can be represented as a recurring decimal form then it is called as Irrational number
These are of the form [tex]\sqrt[n]{x}[/tex] where we can not simplify positive integer x
Example = [tex]\sqrt{2}[/tex] , [tex]\sqrt{3}[/tex] ,[tex]\sqrt[3]{5}[/tex]
These both types of numbers belong to the category of Real numbers as they fall on Real number line.
Rational numbers with denominators = 1 are called as Integers
Surds are the categories of Irrational numbers are
Surds are the values of square root of any positive number that can not be simplified further to a whole number
Some examples of Surds are [tex]\sqrt{2}[/tex] and [tex]\sqrt{3}[/tex]

(CESGRANRIO) Determine o parâmetro m na equação x²+mx+m²-m-12=0, de modo que ela tenha uma raíz nula e outra positiva.
Answers
Pede-se para determinar o parâmetro "m" da equação abaixo, sabendo-se que uma raiz é nula e a outra é positiva:
x² + mx + m² - m - 12 = 0
Veja que se uma raiz é nula (é igual a zero), então vamos substituir o "x" por "0", na equação acima:
0² + m*0 + m² - m - 12 = 0
0 + 0 + m² - m - 12 = 0
m² - m - 12 = 0 ------resolvendo essa equação do 2º grau você encontrará as seguintes raízes:
m' = -3
m'' = 4
Dessa forma, vamos substituir "m" por (-3) e por 4 e ver se a equação terá uma raiz nula e outra positiva. Vamos ver?
Substituindo "m" por "-3", ficamos com:
x² - 3x + (-3)² - (-3) - 12 = 0
x² - 3x + 9 + 3 - 12 = 0
x² - 3x +12 - 12 = 0
x² - 3x = 0 <------Veja que as raízes dessa equação são: x' = 0 e x'' = 3
Veja que para m = -3, a equação se verifica, pois temos uma raiz igual a "0" e a outra positiva (igual a 3).
Agora vamos substituir "m" por 4 na equação original:
x² + 4x + 4² - 4 - 12 = 0
x² + 4x + 16 - 16 = 0
x² + 4x = 0 <----- Veja que as raízes dessa equação são: x' = 0 e x'' = -4.
Observe que, para m = 4, a equação NÃO se verifica, pois temos uma raiz igual a "0" e a outra negativa (igual a -4). E no enunciado é informado que uma raiz deverá ser nula e a outra positiva. Como deu uma nula e a outra negativa, então m = 4 não convém.
Logo, o valor de "m" deverá ser:
m = -3 <----Pronto. Essa é a resposta.
Is 13-yard gain a positive or negitave integer?Explain the meaning of zero in this situation.
Answers
Answer:
Positive integer
Step-by-step explanation:
An integer is a collection of positive and negative number and zero
Positive Numbers: Positive number are the numbers which have positive sign. For example 4, 9 or which which represents positivity like gain , increase, profit etc
Negative numbers: Negative number are the numbers which have negative sign. For example -4, -9 or which which represents negativity like loss , decrease etc
Zero is neither a negative number nor a positive number.
13 yard is a positive because there is a gain , which represent positivity.
We can also write + 13 yard.
Hence, the correct answer is it is a positive integer

2 1/9 of what number is 76?
Answers
Then, (19/9)·y = 76;
19·y = 9·76;
19·y = 684;
y = 684/19;
y = 36 ( is the number);
The value of the unknown number is 36. 2 1/9 of 36 is 76.
The is the value of the missing number?Given the parameter:
2 1/9 of what number is 76?
To solve for the unknown value, first, convert the mixed fraction to an improper fraction:
2 1/9 = ( 9×2 + 1 )/9 = 19/9
Now, we set up the equation:
Let 'x' represent the unknown number:
19/9 of x is 76
19/9 × x = 76
Solve for x:
19x/9 = 76
19x = 9 × 76
19x = 684
x = 684/19
x = 36
Therefore, the value of x is 36.

To solve this problem, we simply have to use ratio and proportion. We know that for every 5 cm, we have 1 m therefore the factor to use is:

If Olivia ate 4 times as much salad as Reagan, then she ate r amount multiplied by 4:
4r
Thus, the equation than can be used to describe the amount of salad for Olivia is:
4r = v
