The fraction of the contestants are dogs which are 17/48.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We have been given that there are dogs, cats, and rabbits.
480 contestants altogether. 1/2 of the contestants are cats, and 1/6 of the contestants are rabbits.
Total = 480
Cats = 1/2 x 480 = 240
Rabbit = 1/6 x 480 = 70
Then; the Number of dogs are
480 - 70 - 240
= 170
Therefore, a fraction of the contestants are dogs which is
170/480 = 17/48
Hence, the fraction of the contestants are dogs which are 17/48.

Find the equation of the line that is perpendicular to y=-1/5x-3 and contains the point (1,2).
The equation of line will be;
⇒ y = 5x - 3
What is Equation of line?
The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The perpendicular line is,
y = -1/5x - 3
And, The point contain by the line = (1 , 2)
Now,
We need to find the slope of line.
Since, Product of slopes of perpendicular lines are - 1.
So, we find the slope of perpendicular line as;
y = -1/5x - 3
dy/dx = -1/5
So, The slope of the line = - (1/-1/5) = 5
Hence, The equation of line passing through the points (1, 2) and with slope 5 is defined as;
y - y₁ = m (x - x₁)
y - 2 = 5 (x - 1)
y - 2 = 5x - 5
y = 5x - 5 + 2
y = 5x - 3
Thus, The equation of line will be;
⇒ y = 5x - 3

Eva sees a dolphin 3.2 meters below sea level and a bird 47/10 meters above sea level.
Which of the following expressions represents the vertical distance between the dolphin and the bird?
47/10-(3.2)
3.2-47/10
none of the above
Answer:
[tex]A[/tex], | [tex]\frac{47}{10} -(3.2)[/tex] |
To find the vertical distance between a dolphin below sea level and a bird above sea level, the absolute values of their distances from sea level must be added, resulting in a distance of 4.7 + 3.2 meters, which means the correct answer is 'none of the above'.
Explanation:The question is asking to calculate the vertical distance between a dolphin below sea level and a bird above sea level. To find this vertical distance, you would add the absolute values of their distances from sea level. Since sea level is our reference point, and the dolphin is at 3.2 meters below it while the bird is at 47/10 or 4.7 meters above, the expression to represent the vertical distance between the dolphin and the bird would be:
4.7 + 3.2
The correct answer is none of the above since neither of the provided expressions represents the sum of the two distances. Instead, each expression attempts to subtract one distance from the other, which is not the correct method for finding the vertical distance between two objects on opposite sides of the sea level reference point.

Buehlermaci,
The answer is option A "scarcity." It's not option B because economics is the distribution or a production of a item. It's not option C because opportunity cost is when you are looking at the value of two things before you make a decision on which you want kinda like pros and cons. Scarcity is the shortage on a resource but the person decides to spend it on wants and needs so basically the difference between limited resources and wants and needs.

Find the values of y2.
y2=169
please i need help stuck on it :)
assuming you mean y² = 169
then taking the square root of both sides gives
y = [tex]\sqrt{169}[/tex] = ± 13
since 13² = 169 and (- 13)² = 169
The values of y are -13 and 13 in the equation y^2 = 169.
It is given that the expression [tex]\rm y^2 = 169[/tex]
It is required to find the values of y.
What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
We have a quadratic equation:
[tex]\rm y^2 = 169[/tex]
[tex]\rm y^2-169=0[/tex] (subtract 169 on both sides)
[tex]\rm y^2- 13^2=0[/tex] (169 = 13²)
(y+13)(y-13) = 0 (a²-b² = (a+b)(a-b))
Taking (y+13) = 0 ⇒ y = -13
Taking (y-13) = 0 ⇒ y = 13
Thus, the values of y are -13 and 13 in the equation y^2 = 169.

what is the simplified form of the following expression? Assume x is greater than or equal to 0 and y is greater than or equal to 0. 2(4sq root16x)-2(4sq root 2y)+34 sq root 81x)-4(4sq root32y)
The simplified expression is [tex]\(338\sqrt{x} - 40\sqrt{2y}\),[/tex] combining like terms of square roots of variables.
To simplify the given expression, let's simplify each term separately:
1. [tex]\(2 \cdot 4\sqrt{16x}\)[/tex]
- Simplify \(4\sqrt{16x}\): Since [tex]\(16x = (4 \cdot 4) \cdot x = 4^2 \cdot x\), the square root of \(16x\) is \(4\sqrt{x}\).[/tex]
- Substitute this result into the expression:[tex]\(2 \cdot 4 \cdot 4\sqrt{x} = 32\sqrt{x}\).[/tex]
2. [tex]\(2 \cdot 4\sqrt{2y}\) - Simplify \(4\sqrt{2y}\): Since \(2y\) doesn't have a perfect square factor, we leave it as is. - Substitute this result into the expression: \(2 \cdot 4\sqrt{2y} = 8\sqrt{2y}\).[/tex]
3. [tex]\(34\sqrt{81x}\) - Simplify \(\sqrt{81x}\): Since \(81x = (9 \cdot 9) \cdot x = 9^2 \cdot x\), the square root of \(81x\) is \(9\sqrt{x}\).[/tex]
- Substitute this result into the expression: [tex]\(34 \cdot 9\sqrt{x} = 306\sqrt{x}\).[/tex]
4. [tex]\(4 \cdot 4\sqrt{32y}\) - Simplify \(4\sqrt{32y}\): Since \(32y = (4 \cdot 8) \cdot y = 4^2 \cdot 8y\), the square root of \(32y\) is \(4\sqrt{8y}\). - Rewrite \(\sqrt{8y}\) as \(2\sqrt{2y}\) since \(8 = 4 \cdot 2\). - Substitute this result into the expression: \(4 \cdot 4 \cdot 2\sqrt{2y} = 32\sqrt{2y}\).[/tex]
Now, combine all the simplified terms:
[tex]\[ 32\sqrt{x} - 8\sqrt{2y} + 306\sqrt{x} - 32\sqrt{2y} \][/tex]
Combine like terms:
[tex]\[ (32\sqrt{x} + 306\sqrt{x}) - (8\sqrt{2y} + 32\sqrt{2y}) \][/tex]
[tex]\[ 338\sqrt{x} - 40\sqrt{2y} \][/tex]
Therefore, the simplified form of the expression is [tex]\(338\sqrt{x} - 40\sqrt{2y}\).[/tex]
The simplified form of the expression is 338√x - 72√2y, after applying the square roots to known perfect squares and combining like terms.
To simplify the expression, first apply the square root to known perfect squares and distribute the multiplication:
2(4√16x) becomes 2(4×4√x) because √16 = 4, so this part simplifies to 32√x.
2(4√2y) stays as is because √2y cannot be simplified further without more information about y, so this part is 8√2y.
34√81x can be simplified because √81 = 9, resulting in 34×9√x, which is 306√x.
4(4√32y) becomes 4(4×√16×√2y) because √32 = √16×√2, so this part simplifies to 64√2y.
Combining all the parts, we subtract the like terms:
32√x - 8√2y + 306√x - 64√2y
This simplifies further to 338√x - 72√2y
That is the final simplified expression.

All angles in the diagram are measured to the nearest degree.
Work out the upper bound and lower bound of angle x.
Answer:
=59+108+81+x=360
=248+x=360
=112
Considering the nearest-degree measurements, angle x falls between 58.5 and 108.5 degrees, determined by adjusting the upper and lower bounds based on the provided angles in the diagram.
Given that the angles in the diagram are measured to the nearest degree, we can determine the upper and lower bounds of angle x using the provided angles: 59 degrees, 108 degrees, and 81 degrees.
To find the upper bound of angle x, we select the largest angle, which is 108 degrees. The upper bound is obtained by adding 0.5 degrees to this angle (since measurements are to the nearest degree). Therefore, the upper bound of angle x is 108 + 0.5 = 108.5 degrees.
For the lower bound, we choose the smallest angle, which is 59 degrees. The lower bound is found by subtracting 0.5 degrees from this angle. Thus, the lower bound of angle x is 59 - 0.5 = 58.5 degrees.
In conclusion, the measure of angle x lies between the lower bound of 58.5 degrees and the upper bound of 108.5 degrees.

A rental car cost a one time fee of $30 and then an additional $15 for each day it is rented. If the Webb family’s total bill was $135, how many days did they rent the car?
Answer:
7 days because 15 times 7 =105 and if you add 30 to that you get 135.
Step-by-step explanation:
The Webb family rented the car for 7 days.
To find the number of days the Webb family rented the car, we can set up an equation using the given information. Let's say the number of days the car was rented is x. The total cost would then be $30 (one-time fee) plus $15 (daily fee) multiplied by x. This can be represented as the equation: 30 + 15x = 135. To solve for x, we need to isolate it by subtracting 30 from both sides: 15x = 105. Then, divide both sides by 15: x = 7. Therefore, the Webb family rented the car for 7 days.

leons older brother is 4and 3/4 feet tall. Leon is 1/3 foot shorter than his brother. How tall is leon
Answer: [tex]4\frac{5}{12}\ feet[/tex]
Step-by-step explanation:
The height of Leon's older brother = [tex]4\frac{3}{4}[/tex] feet
[tex]=\frac{16+3}{4}=\frac{19}{4}[/tex] feet
Since, Leon is 1/3 foot shorter than his brother.
Then, the height of Leon = [tex]\frac{19}{4}-\frac{1}{3}[/tex]
First we need to make them like fractions by multiplying 3 on the numerator and denominator of the first fraction and 4 on the numerator and denominator of the second fraction.
Then, the height of Leon = [tex]\frac{57}{12}-\frac{4}{12}[/tex]
[tex]=\frac{57-4}{12}\\=\frac{53}{12}=4\frac{5}{12}[/tex] feet

In this figure, the horizontal lines are parallel, and AB=BC=CD. Find KL and FF. I need an explanation and all work shown.
AB=BC=CD together with the fact the horizontal lines are parallel implies that HG=GF=FE (can be proved using triangle similarity). So knowing FE=5.1 implies FG=5.1
Since we now know that the horizontal lines are equidistant, it means that ML=LK=KJ (same argument as above). Therefore KL=7.6.
Let me know if you have questions!
Since the horizontal lines are parallel, and AB=BC=CD, the lengths of KL and FG are: D. KL = 7.6; FG = 5.1.
What are parallel lines?In Mathematics and Euclidean Geometry, parallel lines are two lines that are always the same distance apart and never meet.
This ultimately implies that, parallel lines are always coplanar lines and straight lines that have an equal distance between each other.
By critically observing the figure, we can logically deduce that the horizontal lines are all parallel to each other with two transversals;
AB = BC = CD (Given)
AB = LM = 7.6
