There are 133 students at a small school and 23 of them are freshmen. What fraction of the students are freshmen?
Answers
Answer:
23/133
Step-by-step explanation:
If your total is 133, that would become your denominator, your numerator is how many students of those are freshman in which this case is 23.
The total number of freshmen in the school is 23/133
The number of students in the small school is 133
23 out of the 133 students are freshmen
Therefore the fraction of freshmen in the school can be calculated by dividing 23 by 133
Fraction of freshmen is 23/133

Step-by-step explanation:
LORAN is a long range hyperbolic navigation system. Suppose two LORAN transmitters are located at the coordinates (−60,0) and (60,0), where unit distance on the coordinate plane is measured in miles A receiver is located somewhere in the first quadrant. The receiver computes that the difference in the distances from the receiver to these transmitters is 100 miles.
What is the standard form of the hyperbola that the receiver sits on if the transmitters behave as foci of the hyperbola?
Answers
LORAN follows an hyperbolic path.
The equation of the hyperbola is: [tex]\mathbf{\frac{x^2}{2500} + \frac{y^2}{1100} = 1}[/tex]
The coordinates are given as:
[tex]\mathbf{(x,y) = (-60,0)\ (60,0)}[/tex]
The center of the hyperbola is
[tex]\mathbf{(h,k) = (0,0)}[/tex]
The distance from the center to the focal points is given as:
[tex]\mathbf{c = 60}[/tex]
Square both sides
[tex]\mathbf{c^2 = 3600}[/tex]
The distance from the receiver to the transmitters is given as:
[tex]\mathbf{2a = 100}[/tex]
Divide both sides by 2
[tex]\mathbf{a = 50}[/tex]
Square both sides
[tex]\mathbf{a^2 = 2500}[/tex]
We have:
[tex]\mathbf{b^2 = c^2 - a^2}[/tex]
This gives
[tex]\mathbf{b^2 = 3600 - 2500}[/tex]
[tex]\mathbf{b^2 = 1100}[/tex]
The equation of an hyperbola is:
[tex]\mathbf{\frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1}[/tex]
So, we have:
[tex]\mathbf{\frac{(x - 0)^2}{2500} + \frac{(y - 0)^2}{1100} = 1}[/tex]
[tex]\mathbf{\frac{x^2}{2500} + \frac{y^2}{1100} = 1}[/tex]
Hence, the equation of the hyperbola is: [tex]\mathbf{\frac{x^2}{2500} + \frac{y^2}{1100} = 1}[/tex]

Which graph shows a system with one solution?
Answers
Explanation:
A solution is where the lines intersect. Graph A shows exactly one solution, and it is at (-2,2)
Graph B doesn't have any solutions since the lines are parallel, and parallel lines never intersect. We consider this system to be inconsistent.
Graph C has infinitely many solutions. The two lines perfectly overlap, meaning there are infinitely many intersection points. All solutions here are of the form (x,y) = (x,2x-1)

Answers
Answer:
Answer to the first part: 8a³b + 4ab
Step-by-step explanation:
Perimeter = distance around the three sides
P = 6a³b + 2a³b + 4ab
P = (6a³b + 2a³b) + 4ab add like terms
P = 8a³b +4ab Simply
The value of the perimeter and area of the triangle are,
20.52 cm² and 28.68 cm
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Now, By Using Pythagoras theorem to find the base of the triangle as;
a² = 6² - 3²
a ² = 27
a = √27
And, b² = 9² - 3²
b² = 72
b = √72
Hence, Base = √27 + √72
= 13.68
So, We get;
Area = 0.5 x 13.68 x 3
Area = 20.52 cm²
And, The value of perimeter is,
Perimeter = 9 + 6 + 13.68
= 28.68
Thus, The value of the perimeter and area of the triangle are,
20.52 cm² and 28.68 cm
