El porcentaje del descuento aplicado es del 5%.
¿Como encontrar el porcentaje del descuento aplicado?
Recordar que si aplicamos un descuento de X (sería un porcentaje X) a un precio P, entonces el nuevo precio será:
P' = P(1 - X/100)
En este caso, sabemos que el precio origina es 5€ por kilo, y el precio nuevo es 4.75 € por kilo, reemplazando esos numeros en la ecuación de arriba obtenemos:
4.75 = 5*(1 - X/100%)
4.75/5 = 1 - X/100%
X/100% = 1 - 4.75/5
X = (1 - 4.75/5)*100%
X = 5%
Fue un descuento del 5%.

Bryce wants to renovate his kitchen. The construction estimate is $28,400. He can finance through his local bank or directly through the construction company. The bank (loan A) offers a maximum 6-year loan at 8% annual interest, resulting in monthly payments of $497.94.The construction company (loan B) offers a maximum 10-year loan at 5.5% annual interest, resulting in monthly payments of $308.21.Which loan requires Bryce to pay less, and by how much?First, calculate the total payback for each loan.
ANSWER:
Loan A requires Bryce to pay less by $1,133.52
EXPLANATION:
For bank A, we're given;
Length of loan in years(t) = 6 years
Annual interest rate(r) = 8% = 8/100 = 0.08
Loan payment(PMT) = $497.94
Number of compounds per year(n) = 12
We can go ahead and determine the loan amount using the below formula as seen below;
[tex]\begin{gathered} Loan\text{ }amount,P_0=\frac{PMT(1-(1+\frac{r}{n})^{-nt})}{\frac{r}{n}} \\ \\ =\frac{497.94(1-(1+\frac{0.08}{12})^{-12*6}}{\frac{0.08}{12}} \\ \\ =\text{ \$}28399.77 \end{gathered}[/tex]So we can see that Bryce will pay back;
[tex]\begin{gathered} Bank\text{ }A\text{ }Loan\text{ }Payback=497.94(12*6) \\ \\ =497.94\left(72\right) \\ \\ =\text{\$}35,851.68 \end{gathered}[/tex]For bank B, we're given;
Length of loan in years(t) = 10 years
Annual interest rate(r) = 5.5% = 5.5/100 = 0.055
Loan payment(PMT) = $308.21
Number of compounds per year(n) = 12
We can go ahead and determine the loan amount using the below formula as seen below;
[tex]\begin{gathered} Loan\text{ }amount,P_0=\frac{PMT(1-(1+\frac{r}{n})^{-nt})}{\frac{r}{n}} \\ \\ =\frac{308.21(1-(1+\frac{0.055}{12})^{-12*10}}{\frac{0.055}{12}} \\ \\ =\text{ \$}28399.57 \end{gathered}[/tex]So we can see that Bryce will pay back;
[tex]\begin{gathered} Bank\text{ B }Loan\text{ }Payback=308.21(12*10) \\ \\ =308.21\left(120\right) \\ \\ =\text{\$}36985.20 \end{gathered}[/tex]We can see that Bryce will pay back $35,851.68 for Loan A and $36,985.20 for Loan B, so Loan A requires Bryce to pay less and by $1,133.52

Taylor received a paycheck of $1575. First, she spent 30% of her paycheck to make a house payment. Next, she spent 3/14 of the remaining amount to make a car payment. What amount was still left over from Taylor's paycheck after these two payments?
$866.25
1) Gathering the data
$1575
she spent 30%
she spent 3/14
2) Let's calculate it, starting with the 30% expense. Writing a factor, we have already the value:
1575 x ( 1 -0.3)
1575 x (0.7)
1102.50
Now let's proceed with the deduction of 3/14, which can be calculated through that:
1102.5 -3/14x (1102.5)
$866.25
3) Hence, Taylor's balance was after those payments of $866.25

Answer:
The tank is currently 40% (40 percent) full.
Step-by-step explanation:
We can find this by dividing the current fullness (648 gal) by the full tank (1620 gal).
648 / 1620 = 0.4
0.4 = 40%
How do we know to divide 648 by 1620 and not the other way around?

1. What is the equation of the line in standard form? A302-10
Question: What is the equation of the line in standard form?
The standard form for a line is :
y = mx + b
where m is the slope and b is the intercept with y axis.
First, we are going to find the slope, choosing any two points on the line. For example (X1, Y1) = (-4,0) and (X2, Y2) = (0,3). Then, by definition the slope is:
[tex]m\text{ = }\frac{Y2\text{ - Y1}}{X2\text{ - X1}}\text{ = }\frac{3-0}{0-(-4)}\text{ = }\frac{3}{0+\text{ 4}}\text{ = }\frac{3}{4}[/tex]so, our new line equation would be:
[tex]y\text{ = mx + b = }\frac{3}{4}x\text{ + b}[/tex]that is:
[tex]y\text{ = }\frac{3}{4}x\text{ + b}[/tex]Now, we are going to find the y-intercept. This is also accomplished by picking two points on the line and solving for b. For example (X2, Y2) = (0,3). So, for above equation we have:
[tex]3\text{ = }\frac{3}{4}(0)\text{ + b}[/tex]then
[tex]3\text{ = 0 + b = b}[/tex]Then, we have b = 3.
Now, replacing the values of the slope and the intercept previously found, we obtain the equation of the line :
[tex]y\text{ = mx + b = }\frac{3}{4}x\text{ + }3[/tex]that is
[tex]y\text{ = }\frac{3}{4}x\text{ + }3[/tex]Jerome is making beef stew for his family. The recipe calls for 3.5 pounds (lbs.) of stew meat. He notices that he has 1.25 pounds (lbs.) in his refrigerator. How much stew meat should buy when he goes to the grocery in order to have enough? a) What operation (add, subtract, multiply or divide) would you use to solve this? b) How did you know?
EXPLANATION
Let's see the facts:
Call for---> 3.5 lbs of stew meat
Refrigerator -------> 1.25 lbs stew meat
He would buy:
Required - Available ----> 3.5 - 1.25 = 2.25 lbs of stew meat
The operation that we apply is subtraction because 3.5lbs (required) is greater than 1.25lbs (available).
Given two sides of a triangle, find a range of possible lengths for the third side.

The random variable x has a normal distribution with standard deviation. It is known that the probability that x exceeds is. 90. Therefore, mean of the probability distribution is 133.09.
We are given that the random variable x has a normal distribution with standard deviation 21,i.e;
X ~ N( u, σ=21)
The Z probability is given by;
Z = X- u/σ ~ (0,1)
Also, it is known that the probability that x exceeds 160 is 0.90 ,i.e;
P(X > 160) = 0.90
P( X-u/σ > 160-u /21 ) = 0.90
From the z% table we find that at value of x = -1.2816, the value of
P(X > 160) is 90%
which means; 160-u /21 = -1.2816
160 - = 21*(-1.2816)

Determine g(x + a) - g(x) for the following function.g(x) = 3x^2 - 5x
Answer:
3a² + 6ax + 5a
Explanation:
Given the following function
g(x) = 3x² - 5x
Determine g(x+a)
g(x+a) = 3(x+a)² - 5(x+a)
Expand the result
g(x+a) = 3(x² + 2ax + a²) - (5x - 5a)
g(x+a) = 3x² + 6ax + 3a² - 5x + 5a
Determine g(x + a) - g(x)
g(x + a) - g(x) = 3x² + 6ax + 3a² - 5x + 5a - (3x² - 5x)
g(x + a) - g(x) = 3x² + 6ax + 3a² - 5x + 5a - 3x² + 5x
Collect the like terms
g(x + a) - g(x) = 3x² - 3x² - 5x + 5x + 6ax + 3a² + + 5a
g(x + a) - g(x) = 6ax + 3a² + 5a
g(x + a) - g(x) = 3a² + 6ax + 5a
Hence the required result for the function g(x + a) - g(x) is 3a² + 6ax + 5a
