Answer:
A partir del problemas vamos a crear una ecuación donde X es una docena de huevos y Y una libra de mantequilla
entonces: 4 docenas de huevos y 3 libras de mantequilla es igual a 14.100
en mi primera ecuación seria: 4X + 3Y = 14.100
ahora haremos la segunda ecuacion: tres docenas y 1 libra de mantequilla
en mi segunda ecuación seria: 3X + 1Y = 8.700 el plan es sumar las dos ecuaciones pero yo quiero que al sumarlas la variable "Y" desaparezca así que mi segunda ecuación la voy a multiplicar pór (-3) quedándome todo así:
primera ecuación: 4X + 3Y = 14.100
segunda ecuacion multiplicada por -3: -9X - 3Y = -26.1
al sumarlas obtengo como resultado: -5X = -12
resolviendo esa ecuacion obtengo que X=
X=2.4
luego reemplazas X en la primera ecuación: 4X + 3Y = 14.100
reemplazando seria: 4 x (2.4) + 3Y =14.100
9.6 + 3Y = 14.1000
3Y= 14.100 - 9.6
Y=
Y=1.5
entonces concluimos que la docena de huevos cuesta 2.4 $ y la libra de mantequilla 1.5 $

Identify the slope and y-intercept of the function y=-11x+6. O A. The slope is 11. The y-intercept is (0,6). OB. The slope is 6. The y-intercept is (0, 11). O C. The slope is -11. The y-intercept is (0,6). o D. The slope is 6. The y-intercept is (0, -11).
Answers
Answer:
c. The slope is -11 and the y-intercept is (0,6)
Step-by-step explanation:
the slope formula is y=mx+b, where m= slope, and b is the y-intercept. so that would mean -11x is the slope and (0,6) is the y-intercept
so that would make c the correct answer.

A tire manufacturer knows that 5% of tires contain a defect, and the presence of a defect is independent from tire to tire.
What is the probability that if 5 tires are inspected, exactly 1 has a defect?
Round to 3 decimal places.
Answers
Answer:
the answer is 0.204
Step-by-step explanation:
The probability that if 5 tires are inspected, exactly 1 has a defect is 0.204
How to determine the probability?The probability that a tire is defect is given as:
p = 5%
The required probability is then calculated using:
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n - x}[/tex]
Where:
n = 5 --- number of tires
x = 1 ---number of tires with defect
So, we have:'
[tex]P(1) = ^5C_1 * (5\%)^1 * (1 - 5\%)^{5 - 1}[/tex]
This gives
[tex]P(1) = 5 * (5\%) * (1 - 5\%)^4[/tex]
Evaluate the product
P(1) = 0.204
Hence, the probability that if 5 tires are inspected, exactly 1 has a defect is 0.204

The answer is B, S=20R+60.
Step-by-step explanation:
To check if the answer is true we can plug in the numbers. For the first line, it would be S = 20(20) + 60. 20 times 20 = 400, and 400 + 60 is 460. 460 is the number of seats in the row so the answer is true.

Name the constant of variation for y equals 1/4x then find the slope of the (0,0) and (4,1)... please
Answers
Answer:
Constant of variation: 1/4
Slope of the line: 1/4
Step-by-step explanation:
The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.
The slope formula states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

The second H-shaped polygon is a scaled copy of the first. The height of the original H is 5 units. The width is 10. The center bar is 4 across. The height of the copy is about 1.25 units. The width is about 2.5. The center bar is 1 across. Show one pair of corresponding points and two pairs of corresponding sides in the original polygon and its copy. Consider using colored pencils to highlight corresponding parts or labeling some of the vertices. What scale factor takes the original polygon to its smaller copy? Explain or show your reasoning.
Answers
Answer:
a. See attachment 2
b. Scale factor is 1/4
Step-by-step explanation:
See attachment 1 for complete question
Given
Original
[tex]Height = 5[/tex]
[tex]Width = 10[/tex]
[tex]Center = 4[/tex]
Scaled Copy
[tex]Height = 1.25[/tex]
[tex]Width = 2.5[/tex]
[tex]Center = 1[/tex]
Solving (a): Corresponding Points & Sides
The corresponding points of the original copy to the scaled copy can be gotten by writing out the measurements as : (x,y)
Where x represents the original and y represents the scaled copy
Taking the height as a point
We have:
[tex]Height: (5,1.25)[/tex]
This will be represented as a dot or point.
A dot at the tip of the line representing height in the original and scaled copy can be colored green
And the width and center as sides
We have:
[tex]Width: (10,2.5)[/tex]
[tex]Center = (4,1)[/tex]
These will be represented by lines
For width:
Two lines representing width in the original and scaled copy respectively can be colored yellow
For center:
Two lines representing center in the original and scaled copy respectively can be colored red
See attachment
Solving (b): The scale factor
To solve for the scale factor, we simply divide the measurement of the scaled copy by the original copy
Recall that:
[tex]Height: (5,1.25)[/tex] , [tex]Width: (10,2.5)[/tex] and [tex]Center = (4,1)[/tex]
Using Height:
[tex]Scale\ Factor = \frac{1.25}{5}[/tex]
This gives:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
For width:
[tex]Scale\ Factor = \frac{2.5}{10}[/tex]
This gives:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
For the center:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
Hence, the scale factor is 1/4
