Answer:
r = (q-16)/6
Step-by-step explanation:
q-10 = 6(r+1)
q-10 = 6r+6
q-10-6 = 6r
q-16 = 6r
r = (q-16)/6
Divide 300 among Ravi and Isha in the ratio 2:3.
Answer:
Ravi: 120
Isha: 180
Step-by-step explanation:
Think of the ratio as parts. Ravi gets 2 parts while Isha gets 3.
But, we don't know how much each gets. This is written as X.
The ratio of 2:3 can be set up in an equation as 2x and 3x.
We know that the total is 300.
[tex]2x+3x=300\\5x=300\\x=60[/tex]
Ravi has 2 parts:
[tex]2(60)=120[/tex]
Isha has 3 parts:
[tex]3(60)=180[/tex]

Is the point (11,5) on the parabola? Show or explain your work.
Answer:
The point (11, 5) is NOT on the parabola.
Step-by-step explanation:
Let [tex](x_0,y_0)[/tex] be any point on the parabola
Let [tex](a, b)[/tex] be the focus
Let [tex]y=c[/tex] be the the directrix
Distance between [tex](x_0,y_0)[/tex] and the focus: [tex]\sqrt{(x_0-a)^2+(y_0-b)^2}[/tex]
Distance between [tex](x_0,y_0)[/tex] and the directrix is [tex]|y_0-c|[/tex]
Given:
focus (6, 4)directrix y = 0Therefore:
Distance between [tex](x_0,y_0)[/tex] and the focus: [tex]\sqrt{(x_0-6)^2+(y_0-4)^2}[/tex]
Distance between [tex](x_0,y_0)[/tex] and the directrix is [tex]|y_0-0|[/tex]
Equate the two expressions and solve for [tex]y_0[/tex]:
[tex]\sqrt{(x_0-6)^2+(y_0-4)^2}=|y_0-0|[/tex]
[tex]\implies (x_0-6)^2+(y_0-4)^}=(y_0-0)^2[/tex]
[tex]\implies {x_0}^2-12x_0+36+{y_0}^2-8y_0+16={y_0}^2[/tex]
[tex]\implies {x_0}^2-12x_0-8y_0+52=0[/tex]
[tex]\implies 8y_0={x_0}^2-12x_0+52[/tex]
[tex]\implies y_0=\dfrac18{x_0}^2-\dfrac{12}{8}x_0+\dfrac{52}{8}[/tex]
[tex]\implies y_0=\dfrac18{x_0}^2-\dfrac32x_0+\dfrac{13}{2}[/tex]
Now rewrite with (x, y):
[tex]\implies y=\dfrac18x^2-\dfrac32x+\dfrac{13}{2}[/tex]
Therefore, this is the equation of the parabola
To determine if the point (11, 5) is on the parabola, input x = 11 into the equation:
[tex]\implies y=\dfrac18(11)^2-\dfrac32(11)+\dfrac{13}{2}[/tex]
[tex]\implies y=\dfrac{41}{8}[/tex]
So the point (11, 5) is NOT on the parabola.
The LaSalle High School senior class raised funds for an end of the year cruise getaway. The city gave them a special package for the port fees and taxes - a flat fee of $1,500 for the entire class's port fees and taxes. It costs $367 per student to board the cruise.

Circle the irrational number in the list below. 7.27, 5, 9215, 2196
Answer:
7.27 is the irrational number
Step-by-step explanation:
7.27 can not turn into a fraction because it keeps on repeating
There are no Irrational numbers in the list.
We have a set of numbers - 7.27, 5, 9215, 2196.
We have to circle out the Irrational ones.
What are Irrational Numbers?Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction - p/q where p and q are integers.
According to the question, we have -
7.27, 5, 9215, 2196
Now -
7.27 = [tex]$\frac{727}{100}[/tex] → It is Rational.
5 = [tex]$\frac{5}{1}[/tex] → It is Rational.
9215 = [tex]$\frac{9215}{1}[/tex] → It is Rational.
9215 = [tex]$\frac{2196}{1}[/tex] → It is Rational.
All the numbers are Rational as they can be expressed in the form of p/q.
Hence, there are no Irrational numbers in the list.
