18 is the number that makes the ratio equivalent to 2:6
How to find the number that makes the ratio equivalent to 2:6?Equivalent ratios are ratios that have the same value, but may have different numerator and denominator values. They are related to each other by multiplication or division of both the numerator and denominator by the same non-zero value.
For example, the ratios 2/4 and 1/2 are equivalent ratios because both represent the same fraction (1/2) and therefore have the same value.
In this case we have:
2:6 = 6: x
2/6 = 6/x
2 * x = 6 * 6
2x = 36
x = 36/2
x = 18
Thus, the number that makes the ratio equivalent to 2:6 is 18

Can anyone help me with the question i circled cuz i couldn't understand them
the equation for the line perpendicular will be y = -5x +11.
What is the equation straight line?
The formula for a straight line is generally expressed as Y = mx + c, where m stands for the slope and c for the y-intercept. In geometry, it is the straight-line version of the equation that is most usually utilised. A straight-line's equation can be expressed in a variety of forms, including point-slope form, slope-intercept form, general form, standard form, etc. An infinitely long straight line has two dimensions and is a geometrical object with two ends. The equations for a straight line that are used the most frequently are y = mx + c and axe + by = c. Point-slope, slope-intercept, standard, general, and other forms are more variations.
The given line is y = x/5 +3
the slope is m = 1/5
So the slope of the perpendicular line will be -5
So the equation of line will be y-3 = m1(x-1)+3
y-3 = -5x+5+3
y = -5x +11
Hence the equation for the line will be y = -5x +11.

A plane, 50 miles away from its destination, is flying toward the airport at an altitude of 30,500 feet. Later, this same plane is 20 miles from the airport and has descended to an altitude of 18,000 ft.
How far has the plane flown?
Answer:
In feet: [tex]\boxed{158,892 \textrm{ feet}}[/tex]
In miles: [tex]\boxed{\textrm{ 3.11 \;miles}}[/tex]
Step-by-step explanation:
A diagram really helps here and so I have drawn one for your understanding
From the diagram we see that Point A refers to the location of the plane when it is 50 miles away from the airport at am altitude of 30,500 feet
In a 2D coordinate system where x refers to the horizontal distance from the airport value and y refers to the altitude,
=> Point A has coordinates (50, 30500)
When the plane is 20 miles away from the airport, the altitude has dropped down to 18000 feet
This location is represented as point B(20, 18000)
The horizontal distance traveled by the plane is 50 - 20 = 30 miles
The vertical distance traveled by the plane(drop in altitude) is 30,500 - 18,000 = 12, 500
These two form the legs of a right triangle with the actual path of descent as the hypotenuse of the right triangle (see figure)
The distance c traveled by the plane is the distance from Point A to Point B which can be computed using the Pythagorean theorem given the two legs of the right triangle
The general formula is :
[tex]\mbox{\large c = \sqrt{a^{2} + b^{2}}}[/tex]
where c is the length of the hypotenuse, a and b are the lengths of the other two sides
We have a = 12, 500 feet and b = 30 miles
Convert miles to feet to get same units:
a = 12, 500 feet
b = 30 miles = 30 x 5280 feet = 158400
[tex]\mathbox{ c = \sqrt{158400^{2} + 12500^{2}}}[/tex]
[tex]c = \sqrt{25090560000 + 156250000}[/tex]
[tex]c = \sqrt{25246810000}[/tex]
[tex]\mathrm{c = 158,892.45 \;feet}\\[/tex]
[tex]\mathbox{ \textrm{c = 158,892 feet (to the nearest foot)}}[/tex]
So the distance traveled by the plane is 158, 992 feet (to the nearest foot)
This works out to 158992/5280 miles = 30.11 miles which is pretty close to 3.09
Maybe you are required to answer in feet and not in miles.

Create a graph of the equation 3y=-6x-12
Answer:
Step-by-step explanation:
To graph the equation 3y = -6x - 12, we can start by finding the x and y intercepts.
The x-intercept is the point where y = 0, so we can substitute 0 for y in the equation:
3y = -6x - 12
3 * 0 = -6x - 12
0 = -6x - 12
12 = -6x
x = -2
So the x-intercept is (-2, 0).
The y-intercept is the point where x = 0, so we can substitute 0 for x in the equation:
3y = -6x - 12
3y = -6 * 0 - 12
3y = -12
y = -4
So the y-intercept is (0, -4).
Now that we have the x and y intercepts, we can plot the points on the graph and draw a line that passes through both points. This line will be the graph of the equation.
In this case, the graph of the equation 3y = -6x - 12 is a downward sloping line that passes through the points (-2, 0) and (0, -4).

The total number of socks are n, 3 of which are red. when 2 socks are chosen randomly from the box, the probability of both socks being red is 1/2 so the value of n is 4.
The information given by question is
Total number of socks = n
Number of red socks = 3
when 2 socks are chosen randomly from the box
Probability of both socks being red = 1/2
Ways of choosing 2 socks from n = [tex]_nC_2[/tex]
Ways of choosing 2 red socks from 3 = [tex]_3C_2[/tex]
Probability of both socks being red = [tex]\frac{_3C_2}{_nC_2}[/tex]

In a bag of 10 marbles, there are 4 blue, 3 red, 2 green, and 1 yellow. What is the probability that you draw one marble that is blue, DO NOT replace it, and draw another marble that is green?
The probability of drawing one blue marble on the first draw is 4/10. Since we do not replace the marble, there are only 9 marbles left in the bag, so the probability of drawing a green marble on the second draw is 2/9.
The probability of drawing one blue marble and one green marble is the product of the probabilities of each event:
(4/10) x (2/9) = 8/90 = 4/45
Therefore, the probability of drawing one blue marble and one green marble is 4/45.

Find all the zeros of the quadratic function. y=x^2+11x+18 If there is more than one zero, separate them with commas. If there are no zeros, click on "None".
None. The discriminant of the quadratic equation is [tex]b^{2}[/tex]-4ac = [tex]11^{2}[/tex] - 4(1)(18) = 121 - 72 = 49, which is not a perfect square.
What is perfect square ?A perfect square is a number that can be expressed as the product of two equal integers. For example, 9 is a perfect square because it can be written as 3 x 3.
The zeros of this quadratic function can be found by setting the equation equal to 0 and solving for x.
0 = [tex]x^{2}[/tex] + 11x + 18
To solve for x, we can use the quadratic formula:
x = [-b ± √([tex]b^{2}[/tex] - 4ac)]/2a
Substituting in our values from the equation above, we get:
x = [-11 ± √([tex]11^{2}[/tex] - 4(1)(18))]/2(1)
x = [-11 ± √(-63)]/2
Since the square root of a negative number is not a real number, there are no zeros.
Therefore, the answer is None.
So, there are no real solutions.

mike estimated the difference of 79.44 and 6.7 by rounding to the nearest whole.
We can tell that Mike thought the difference would be 72, but it is actually 72.74 by rounding off.
What is rounding off?A number is simplified when it is rounded off, preserving its value while moving it closer to the next number.
It is done for whole numbers as well as decimals at various places of hundreds, tens, tenths, etc.
When numbers are rounded off, the important numbers are kept.
To determine how to round a number, look at the next digit in the appropriate position; if it is less than 5, round down, and if it is greater than 5, round up.
So, Mike determined 79 to be 79.44 and 7 to be 6.7, so he determined the difference as follows:
79 - 7 = 72
Actual numbers that vary are:
79.44 - 6.7 = 72.74

Use superposition to find vo in the given circuit where i1 = 6 a and i2 = 4 a
the voltage across the circuit ([tex]V_{0}[/tex]) is 80 volts.
In the superposition theorem, the voltage across any element in a linear circuit is equal to the sum of the voltages caused by each source acting independently. In other words, in a linear circuit, each source is treated as the only source, and the other sources are replaced with their internal resistances.
With the resistance value of 8 ohms, we can calculate the voltage across the circuit using the superposition theorem.
First, consider [tex]I_{1}[/tex] as the only source, and set [tex]I_{2} = 0 A[/tex]. The voltage across the circuit can be found using Ohm's law (V = IR), where R is the resistance in the circuit.
[tex]V_{1} = i1 * R = 6 A * 8 ohms = 48 V[/tex]
Next, consider [tex]I_{2}[/tex] as the only source, and set [tex]I_{1} = 0 A[/tex]. The voltage across the circuit can be found using Ohm's law (V = IR), where R is the resistance in the circuit.
[tex]V_{2} = i2 * R = 4 A * 8 ohms = 32 V[/tex]
Finally, the voltage across the circuit ([tex]V_{0}[/tex]) is the sum of the voltages found in steps 1 and 2.
[tex]V_{0} = V_{1} + V_{2} = 48 V + 32 V = 80 V[/tex]
So, the voltage across the circuit ([tex]V_{0}[/tex]) is 80 volts.

What is quadratic model?A method of simulating the relationship between two sets of variables is quadratic regression. The outcome is a regression equation that may be applied to the data to generate predictions. The formula for the equation is: y = ax² + bx + c, where a ≠ 0. Situations that may be approximated by quadratic functions include tossing a ball, firing a cannon, jumping from a platform, and striking a golf ball. Researchers may find the quadratic model to be a useful tool for data analysis in identifying the combined impact of success objectives on academic accomplishment. We anticipate that future studies on the impact of academic performance objectives will frequently use the quadratic model to analyse their data.
Given that,
T = 0.0002x² - 316x + 127.9
exposure time = T
Now, calculate exposure time when x = 560
So, T = 0.0002x² - 0.316x + 127.9
T = 0.0002×(560)² - 0.316 × (560) + 127.9
T = 62.72 - 176.96 + 127.9
T = 13.66 hour

1 4/5 bags of dog food will last the LPS for approximately 8 and 3/10 days, or 8.3 days.
The Logan pet store uses 9/10 of a bag of dog food every day, which means they need 9/10 * 1 bag = 9/10 bags of dog food per day. To determine how many days 1 4/5 bags of dog food will last,
we need to divide the total amount of dog food by the amount used per day: 1 4/5 bags / (9/10 bags/day) = (9/10)*(18/5) / (9/10) = 18/5 days. Therefore, 1 4/5 bags of dog food will last for 18/5 days.
One 4/5 bags of dog food will last the Logan Pet Store (LPS) for approximately 8 and 3/10 days. This is because if the LPS uses 9/10 of a bag of dog food every day, then they are using 9/10 * 5/5 = 9/10 bags of dog food per day. If we divide 1 4/5 bags of dog food by 9/10 of a bag per day, we get (1 4/5) / (9/10) = (18/5) / (9/10) = 18/5 * 10/9 = 20/9 days.
