Answer:
[tex]z = 362\,botellas[/tex]
Step-by-step explanation:
(This exercise has been presented in Spanish and for that reason explanation will be held in Spanish)
La cantidad de botellas de 0,25 litros que se llenan con 49 litros de yogurt es:
[tex]x = \frac{49\,L}{0.25\,\frac{L}{botella} }[/tex]
[tex]x = 196\,botellas[/tex]
La cantidad remanente de yogurt es:
[tex]V_{r} = 132\,litros - 49\,litros[/tex]
[tex]V_{r} = 83\,litros[/tex]
Ahora, la cantidad de botellas de 0,5 litros que se llenan con el volumen remanente es:
[tex]y = \frac{83\,litros}{0.5\,\frac{litros}{botella} }[/tex]
[tex]y = 166\,botellas[/tex]
Finalmente, el total de botellas a llenar es:
[tex]z = 196\,botellas + 166\,botellas[/tex]
[tex]z = 362\,botellas[/tex]

Make x the subject of Y=4x+3
The value of x from the expression is,
⇒ x = 1/4 (Y - 3)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ Y = 4x + 3
Now, We can solve the expression for the value of x as;
⇒ Y = 4x + 3
Subtract 3, we get;
⇒ Y - 3 = 4x + 3 - 3
⇒ Y - 3 = 4x
Divide by 4;
⇒ (Y - 3) / 4= 4x/4
⇒ (Y - 3)/4 = x
⇒ x = 1/4 (Y - 3)

A gym offers three levels of membership based on the number of visits per month, as represented by the table. Kaleigh wants to know how much she will pay for her gym membership. Which graph represents the total monthly cost at the gym as a function of the number of visits Kaleigh plans to make each month?
Answer:
graph one
Step-by-step explanation:
Let
x ----> the number of visit per month
y ----> the total cost
we know that
Observing the table
1) For the interval of x equal to ----> [0,12] (close circle both points)
The domain is all whole numbers greater than or equal to 0 visits and less than or equal to 12 visits
The value of y is
y=5x+15
For x=0 ----> y=$15
For x=12 ----> y=5(12)+15=$75
The range is the interval ----> [15,75] (close circle both points)
All real numbers greater than or equal to $15 and less than or equal to $75
2) For the interval of x equal to ---->(12,16] (open circle at left and close circle at right)
The domain is all whole numbers greater than 12 visits and less than or equal to 16 visits

The graph that represents the total monthly cost at the gym as a function of the number of visits in a month is shown by option A)
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Based on the number of visits each month, a gym provides three different levels of membership.
Let the monthly visits be 'a' and the overall expense be 'b'. The following will be the appropriate graph showing the total monthly cost of the gym as a function of monthly visits:
A) For the interval of a = [0,12]
The value of b is given by:
b = 5a + 15
when a = 0 in the above equation.
b = $15
when a = 12 in the above equation.
b = 60 + 15
b = $75
The interval of b = [15,75]
B)
For the interval of a = [12,16]
The value of b is given by:
b = 4a + 32
when a = 12 in the above equation.
b = 48 + 32
b = $80
when a = 16 in the above equation.
b = 64 + 32
b = $96
The interval of b = [80,96]
C)
For the interval of a = [16,24]
The value of b is given by:
b = 3a + 42
when a = 16 , we get
b = 48 + 42
b = $90
when a = 24 in the above equation , we get
b = 72 + 42
b = $114
The interval of b = [90,114]
Hence , the graph is represented by graph A

Is 6.584 a rational
number?
Answer:
Step-by-step explanation:
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 6.584, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.
Therefore, in this case we multiply the numerator and denominator by 1000 to get the following fraction: 6584 / 1000
Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.
The GCD of 6584 and 1000 is 8. When we divide the numerator and denominator by 8, we get the following: 823 / 125
Therefore, 6.584 as a fraction is as follows: 823 / 125

La base de una cartulina rectangular mide 8 cm de altura si le recortamos 3 cm a su altura el area de la nueva cartulina seria 126 cm calcula las dimenciones de la cartulina inicial
Answer:
[tex]w=8cm\\h=18.75cm[/tex]
Step-by-step explanation:
Let:
[tex]w=Width\\h=Initial\hspace{3}height\\h_m=Modified\hspace{3}height\\\\Where:\\\\h_m=h-3[/tex]
The area of the cardboard can be calculated using the formula to find the area of a rectangle:
[tex]A=w*h[/tex]
The area of the new cardboard would be:
[tex]A=w*h_m\\\\Where:\\\\w=8\\h_m=h-3\\A=126[/tex]
So:
[tex]126=8*(h-3)\\\\126=8h-24[/tex]
Solving for h:
[tex]126+24=8h\\\\150=8h\\\\h=\frac{150}{8} =\frac{75}{4} =18.75cm[/tex]
Therefore, the dimensions of the initial cardboard are:
[tex]w=8cm\\h=18.75cm[/tex]
Translation:
Sea:
[tex]w=Ancho\\h=Altura\hspace{3}inicial\\h_m=Altura\hspace{3}modificada\\\\Donde:\\\\h_m=h-3[/tex]
El área de la cartulina se puede calcular usando la fórmula para encontrar el área de un rectángulo:
[tex]A=w*h[/tex]
El área de la nueva cartulina sería:
[tex]A=w*h_m\\\\Donde:\\\\w=8\\h_m=h-3\\A=126[/tex]
Entonces:
[tex]126=8*(h-3)\\\\126=8h-24[/tex]
Resolviendo para h:
[tex]126+24=8h\\\\150=8h\\\\h=\frac{150}{8} =\frac{75}{4} =18.75cm[/tex]
Por lo tanto, las dimensiones de la cartulina inicial son:

Answer:
Option (2)
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Point A is the midpoint of side XZ and point B is the midpoint of side YZ.
Triangle XYZ is cut by line segment AB. Point A is the midpoint of side XZ and point B is the midpoint of side YZ. The length of XY is (5x - 7), the length of AB is (x + 1), and the lengths of XA and ZA are (2x - 2). The lengths of YB and BZ are congruent.
What is AX ?
2 units
4 units
6 units
8 units
From the figure attached,
XYZ is a triangle having A and B as the midpoints of the sides XZ and YZ.
By the theorem of midpoints,
AB = [tex]\frac{1}{2}\text{(XY)}[/tex]
Since AB = (x + 1) and XY = (5x - 7)
(x + 1) = [tex]\frac{1}{2}(5x-7)[/tex]
2x + 2 = 5x - 7
5x - 2x = 2 + 7
3x = 9
x = 3
Therefore, side AB = 3 + 1 = 4 units
Side XY = (5x - 7)
= 15 - 7
= 8 units
Side XA = 2(x - 1)
= 4 units
Therefore, Option (2) will be the answer.

Answer:
-9/2
Step-by-step explanation:
Begin by subtracting 2y from both sides
(2y - 2y) - 3 = (4y - 2y) + 6
-3 = 2y + 6
Then, subtract 6 from both sides
(-3 - 6) = 2y + (6 - 6)
-9 = 2y
Finally, divide by 2 on each side
(-9/2) = (2y/2)

In a random survey of 226 college students, 20% reported being "only" children (no siblings). The standard deviation is 2%.
Determine the confidence interval that is likely to contain the percent of all students nationwide who are only children.
Answer:
The confidence interval that is likely to contain the percent of all students nationwide who are only children is (0.1505,0.2554)
Step-by-step explanation:
Total number of students = n = 226
We are given that 20% reported being "only" children (no siblings).
Number of students being "only" children (no siblings) [tex]= 20\% \times 226=\frac{20}{100} \times 226=45.6\sim46[/tex]
So, x = 46
[tex]p=\frac{x}{n}=\frac{46}{226}=0.203[/tex]
Z at 95% is 1.96
Formula for confidence interval for sample proportion :
[tex]CI=p \pm Z \times \sqrt{\frac{p(1-p)}{n}}[/tex]
Substitute the values in the formula :
[tex]CI=0.203 \pm 1.96 \times \sqrt{\frac{0.203(1-0.203)}{226}}\\CI=(0.1505,0.2554)[/tex]
Hence the confidence interval that is likely to contain the percent of all students nationwide who are only children is (0.1505,0.2554)
