The given problem can be solved by setting up and solving a system of linear equations. By assigning variables x, y, and z to represent the three unknown numbers and translating the relationships given in the problem into equations, we can then solve for the unknowns.
Explanation:The subject of this question is algebra and it involves a system of linear equations. Let's denote the three numbers as x, y, and z. We have the following equations based on the problem:
The sum of the three numbers is 132, which gives us the equation: x + y + z = 132. The third number (z) is 7 less than the first (x), which gives us the equation: z = x - 7. The second number (y) is 3 times the third (z), which give us the equation: y = 3z.
Now, let's substitute the second and the third equations into the first to solve for the variables:
Substituting z = x - 7 into y = 3z gives y = 3(x - 7). Substituting z = x - 7 and y = 3(x - 7) into x + y + z = 132 gives x + 3(x - 7) + (x - 7) = 132.
Solving this equation will give the values for x, y, and z that represent the three numbers.

The human eye blinks about 6.25x10 to the 6th power times each year. A seal blinks about 1.01x10 to the 3rd power times per year. How many times do a human and a seal blink in one year?
Answers
A seal blinks 1,010 times a year.
The human eye blinks about [tex]\( 6.25 \times 10^6 \)[/tex] times each year, and a seal blinks about [tex]\( 1.01 \times 10^3 \)[/tex] times per year.
To find out how many times a human and a seal blink in one year, we simply take the given values for each. The question provides us with the number of times a human eye blinks in one year as [tex]\( 6.25 \times 10^6 \)[/tex]times. Similarly, it gives us the number of times a seal blinks in one year as [tex]\( 1.01 \times 10^3 \)[/tex] times.
Therefore, without the need for any additional calculations, we can state that in one year:
- A human blinks [tex]\( 6.25 \times 10^6 \)[/tex] times.
- A seal blinks [tex]\( 1.01 \times 10^3 \)[/tex] times.
These values are already given in the question and represent the total number of blinks for each species in a year. No further calculations are required to answer the question as it is asking for the number of blinks in one year, which is directly provided.
The average weight of 5 students is 150.4 pounds. if no student weighs less than 130 pounds and if no two students' weights are within 5 pounds of each other, what is the most, in pounds, that any one of the students can weight
Answers
You have to make sure to get the lowest average from the other 4 so that you will get a higher value on the 5th person.
If the lowest weight is 130 pounds, assume that one student is 130 and then assume that the other three are 135, 140, 145 to have the lowest combination.
You will then get a mean of these four numbers by adding the unknown value of 'x' of the fifth person.
[130 + 135 + 140 + 145 + x]/5 150.4
(550 + x)/5 = 150.4
550 + x = 752
x = 202 pounds

suppose you randomly choose an integer n between 1 to 5, and then draw a circle with a radius of n centimetres. What is the expected area of this circle to the nearest hundredths of a square centimetres?
Answers
The area of a circle with radius of n centimeters = π(n)^2.
So, the set of possible values are:
n area = π(n^2)
1 π
2 4π
3 9π
4 16π
5 25π
And the expected value of the area may be determined as the mean (average) of the five possible areas:
expected value of the area = [ π+ 4π + 9π + 16π + 25π] / 5 = 11π ≈ 34.5575, which rounded to the nearest hundreth is 34.56
Answer: 34.56
To find the expected area of a circle when randomly selecting an integer n between 1 to 5 as the radius, calculate the area of each possible circle and find the average. The expected area, rounded to the hundredths, is approximately 34.54 cm².
Explanation:When you randomly choose an integer n between 1 to 5, and then draw a circle with a radius of n centimetres, the expected area is calculated by taking the average of the areas for all possible radii.
The area of a circle is given by the formula A = πr². Since the integer n can be 1, 2, 3, 4, or 5, we calculate the area for each of these radii and then find the average.
For n=1: A = π(1)² = π cm²For n=2: A = π(2)² = 4π cm²For n=3: A = π(3)² = 9π cm²For n=4: A = π(4)² = 16π cm²For n=5: A = π(5)² = 25π cm²Add all the areas and divide by the number of possible radii:
Expected Area = (π + 4π + 9π + 16π + 25π) / 5
Expected Area = (55π) / 5
Expected Area = 11π cm²
Now, use the value of π up to two decimal places (3.14) to get the expected area in hundredths of a square centimetre:
Expected Area ≈ 11 × 3.14 cm²
Expected Area ≈ 34.54 cm²
The expected area of the circle, to the nearest hundredths of a square centimetre, is approximately 34.54 cm².

PLEASE HELP!! WILL RATE BRAINLIEST!!
Answers
A. The y-intercept (b) of a linear equation is obtained when x = 0. Therefore from the given table,
y - intercept = 8
Since at time zero the displacement is 8 ft, this means that the horse was already outside the barn initially.
B. The average rate of change of the function represents the slope of the linear equation (m). This can be calculated using the formula:
average rate of change = m = (y2 – y1) / (x2 – x1)
m = (158 – 58) / (3 – 1)
m = 50
C. Since we have determine the y-intercept and the slope, we can formulate the linear equation:
y = m x + b
y = 50 x + 8
The domain is the value of x. When y = 508, x is equivalent to
508 = 50 x + 8
x = 10 hrs

Final answer:
To approximate solutions for the system of equations, enter them into graphing technology, look for intersection points, and match them to the provided coordinates, rounding to the nearest tenth.
Explanation:
To approximate the solution(s) to the system of equations using technology, such as a graphing calculator or graphing software, you typically enter the equations into the device or program and view their intersection points. These intersection points represent the solutions to the system of equations. To get an accurate approximation to the nearest tenth of a unit, you may zoom in on the graph to clearly see where the lines intersect or use the device's built-in features to find the intersection.
You would then compare the given coordinates to the intersection points you found graphically and select the ones that match:
(0,0)
(9.2, 1.5)
(9.6, 3.5)
(5.3, 9.8)
(3.5, 9.6)
Remember to round your values to the nearest tenth as required and to quickly check if these values make sense in the context of the original problem.

You should first solve each equation for y.
Eliminate answer choices with wrong slopes or y intercepts.
Then, because it is a dotted line, the answer will only be < or >.
And because the area is shaded to the right, it would mean that x > y.
So the answer is A) 3x - y > 3
Answer:
The correct option is A.
Step-by-step explanation:
If a line passing through two points then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
From the given graph it is clear that the related line passing through the points (0,-3) and (1,0). So, the equation of related line is
[tex]y-(-3)=\frac{0-(-3)}{1-0}(x-0)[/tex]
[tex]y+3=3x[/tex]
The (0,0) is not in the solution set. So check the equation be (0,0).
[tex]0+3=3(0)[/tex]
[tex]3=0[/tex]
This condition is false if the sign of inequality is < or ≤. Since the related line is a solid line, therefore the sign of inequality must be <.
The required inequality is
[tex]y+3<3x[/tex]
[tex]3<3x-y[/tex]
It is also written as
[tex]3x-y>3[/tex]
Therefore the correct option is A.

A basket contains six apples and five peaches. Three times, you randomly select a piece of fruit, return it to the basket, and then mix the fruit. All three times, the fruit is an apple. Find the probability of this occuring.
Answers
Now as the 3 events are independent we multiply the probs:-
P( apple picked 3 times) = 6/11 * 6/11 * 6/11 = 216/1331 or about 16.2%
Answer:
16.22%
Step-by-step explanation:
A basket contains six apples and five peaches.
Total fruits in the basket = 6 + 5 = 11
The probability of selecting a piece of fruit is an apple [tex]P_{1}=\frac{6}{11}[/tex]
Now return it to the basket and select a fruit. so all events are independent.
Therefore, the probability of each time selecting an apple is same.
Probability=[tex]P_{1}\times P_{2}\times P_{3}[/tex]
P =[tex]\frac{6}{11}[/tex]× [tex]\frac{6}{11}[/tex]×[tex]\frac{6}{11}[/tex]
=[tex]\frac{216}{1331}[/tex] = 16.22%
The probability of all three times the fruit is an apple is 16.22%
Suppose $x$,$y$, and $z$ form a geometric sequence. if you know that $x+y+z=18$ and $x^2+y^2+z^2=612$, find the value of $y$.
Answers
r = y/x = z/y
That is,
y² = xz (1)
We are given:
x + y + z = 18
Therefore
x + z = 18 - y (2)
Also,
x² + y² + z² = 612
Therefore, from (1), obtain
x² + z² + xz = 612
(x + z)² - xz = 612
From (1) and (2), obtain
(18 - y)² - y² = 612
324 - 36y + y² - y² = 612
-36y = 288
y = -8
Answer: y = -8
We use the information that $x$, $y$, and $z$ forms a geometric sequence, and that $x + y + z = 18$ and $x^2 + y^2 + z^2 = 612$ to set up two equations in terms of $y$. These can be solved simultaneously to get the value of $y$.
Explanation:The problem involves a geometric sequence and two simultaneous equations in mathematics. Given $x$, $y$, and $z$ are in a geometric sequence, then they can be represented as $x=y/r$, $y=y$, $z=yr$, where $r$ is the common ratio. This sequence gives us the first equation, $ x + y + z = 18 $.
We have another given equation which is $ x^2 + y^2 + z^2 = 612 $. Substituting $x$, $y$ and $z$ with the terms of the geometric sequence in the second equation, we have $y^2(1/r^2+1+r^2)=612$. Now we have two equations: $ y(1/r+1+r)=18 $ and $ y^2(1/r^2+1+r^2)=612 $, which we can solve simultaneously to find the value of $ y $.
