Lydia gets kicked out of class twice in 20 minutes. How many times will she get kicked out in 6 hours?
Pop Smoke drops 3 new mixtapes per month. How many years has it been if he drops 45 new tapes?
Answer:
for the first answer : 36
for the second answer : 1 year and 3 months
Step-by-step explanation:
first answer :
ahe gets kicked out 2 times in 20 mins
6 hours = 6 × 60 mins = 360 mins
let the number of times she gets kicked out in 6 hours / 360 mins be "n"
therefore ;
n= (360×2) ÷ 20 = 36
therefore answer is 36 times.
-----------------------------------------------------------------
second answer :
3 new tapes in 1 month
let the number of years be "n"
therefore:
3×12 = tapes per year = 36 tapes per year
so, n = 45÷36 = 1 (as quotient) year and 3 (as remainder) months.
answer : 1 year and 3 months

Find the condition that the roots of the quadratic equation
ax2 + cx + C =0
may be in the ratio m:n
Answer:
[tex]mnb^2 = ac(m+n)^2[/tex]
Step-by-step explanation:
Given
[tex]ax^2 +bx + c = 0[/tex]
Required
Condition that the roots is in m : n
Let the roots of the equation be represented as: mA and nA
A quadratic equation has the form:
[tex]x^2 + (sum\ of\ roots)x + (product\ of\ roots)=0[/tex]
or
[tex]x^2 - (\frac{b}{a})x + \frac{c}{a} = 0[/tex]
We have the roots to be mA and nA.
So, the sum is represented as:
[tex]Sum = mA + nA[/tex]
[tex]Sum = A(m + n)[/tex]
And the product is represented as:
[tex]Product = mA * nA[/tex]
[tex]Product = mnA^2[/tex]
By comparing:
[tex]x^2 + (sum\ of\ roots)x + (product\ of\ roots)=0[/tex]
with
[tex]x^2 - (\frac{b}{a})x + \frac{c}{a} = 0[/tex]
[tex]Sum = -\frac{b}{a}[/tex]
[tex]Product = \frac{c}{a}[/tex]
So, we have:
[tex]Sum = -\frac{b}{a}[/tex]
[tex]A(m + n) = -\frac{b}{a}[/tex]
Make A the subject:
[tex]A = \frac{-b}{a(m+n)}[/tex]
[tex]Product = \frac{c}{a}[/tex]
[tex]mnA^2 = \frac{c}{a}[/tex]
Substitute [tex]A = \frac{-b}{a(m+n)}[/tex]
[tex]mn(\frac{-b}{a(m+n)})^2 = \frac{c}{a}[/tex]
[tex]mn\frac{b^2}{a^2(m+n)^2} = \frac{c}{a}[/tex]
Multiply both sides by a
[tex]a * mn\frac{b^2}{a^2(m+n)^2} = \frac{c}{a} * a[/tex]
[tex]\frac{mnb^2}{a(m+n)^2} = c[/tex]
Cross Multiply:
[tex]mnb^2 = ac(m+n)^2[/tex]
Hence, the condition that the ratio is in m:n is
[tex]mnb^2 = ac(m+n)^2[/tex]

Answer:
211 months
Step-by-step explanation:
Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Let the number of months that he prepays for be represented by m
Hence, we have the equation
$20 + $15 × m = $3185
Hence:
20 + 15m = 3185
Collect like terms
15m = 3185 - 20
15m = 3165
m = 3165/15
m = 211 months

Answer:
Discriminant = -92
the equation has no distinct real numbers
Step-by-step explanation:
Given the function f(x) = 4x^2 + 2x + 6 where;
a = 4, b = 2 and c= 6
The discriminant is expessed as D = b^2 - 4ac
Substitute;
D = 2^2 - 4(4)(6)
D = 4 - 96
D = -92
Hence the discriminant is -92.
Since the discriminant is less than zero i.e D< 0, this shows that the zeros of the equation are not real but complex numbers. Hence, the equation has no distinct real numbers
Answer:
-92 is the discriminant
0 real value 0's

Step-by-step explanation:
Trey takes the angle shown, places the point of his compass on S, and draws an arc with an arbitrary radius intersecting the rays of the angle at P and R. Trey claims that as long as he draws two more arcs by placing the needle of his compass on P and then on R, drawing a ray from S through the point at which the arcs intersect, he will be able to bisect ∠S. Is Trey correct?
A. Trey is correct. Since the initial arc was drawn with the point of the compass on S, RS=PS.
B. Trey is not necessarily correct. He will need to ensure that the compass width remains the same for each arc drawn from P and R.
C. Trey is correct. Since the compass is placed on the points P and R to draw the remaining two arcs, the ray drawn through their intersection will bisect the angle.
D. Trey is not necessarily correct. He will need to ensure that the distance from S to P and the distance from S to R are equal.

Write an equation for the nth term of the arithmetic sequence.
2, 5, 8, 11, ...
Answer:
An equation for the nth term of the arithmetic sequence.
[tex]a_n=3n-1[/tex]
Step-by-step explanation:
Given the sequence
2,5,8,11,...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
here
a₁ = 2computing the differences of all the adjacent terms
d = 5-2 = 3, d = 8-5=3, d=11-8=3Using the nth term formula
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = 2, d = 3
[tex]a_n=2+\left(n-1\right)3[/tex]
[tex]=2+3n-3[/tex]
[tex]=3n-1[/tex]
Thus, an equation for the nth term of the arithmetic sequence.
[tex]a_n=3n-1[/tex]

A rectangular page is to contain 36 square inches of print. The margins on each side are 1 inch. Find the dimensions of the page such that the least amount of paper is used.
Given :
A rectangular page is to contain 36 square inches of print.
The margins on each side are 1 inch.
To Find :
The dimensions of the page such that the least amount of paper is used.
Solution :
Let, length and breadth of paper are x and y respectively.
Area is given by :
Area = xy ....1)
xy = 36 inch²
Now, it is given than the margins on each side is 1 inch.
So, area of paper is :
A = ( x + 2 )( y + 2 )
We want area to be minimum.
Putting value of x from 1 , we get :
A = ( 36/y + 2 )( y + 2 )
Now, differentiating above equation and equating with 0 :
[tex]3 - \dfrac{108}{y^2}=0\\\\y = \pm 6[/tex]
Now, we know dimension cannot be negative.
So, y = 6 and x = 6 .
Therefore, length and breadth are 6 and 6 inch respectively.
The length are breadth is x = 6 and y = 6 inch respectively.
Given;
Each rectangular page is to contain 36 square inches of print.
The margins on each side are 1 inch.
We have to find ;
The dimensions of the page such that the least amount of paper is used.
Therefore,
Let, length and breadth of paper are x and y respectively.
Area is given by :
Area = xy
xy = 36 inch²
Now, it is given than the margins on each side is 1 inch.
So, Area of paper is : A = ( x + 2 )( y + 2 )
We want area to be minimum.
Putting value of x from 1 , we get :
A = ( [tex]\frac{36}{y}[/tex] + 2 )( y + 2 )
Now, Differentiating above equation and equating with 0 :
[tex]3 -\frac{108}{y^{2} } = 0[/tex]
[tex]\frac{3y^{2} - 108 }{y^{2} } = 0[/tex]
[tex]3y^{2} - 108 = 0 \\3y^{2} = 108\\y^{2} = \frac{108}{3} \\y^{2} = 36\\y = 6[/tex]
then; xy = 36
6x = 36
x =[tex]\frac{36}{6}[/tex]
x = 6inches
Now, we know dimension cannot be negative.
So, y = 6 and x = 6 .
Therefore, length and breadth are 6 and 6 inch respectively.

shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function. which statement is true?
Answer:
The given equation will have two roots as +5i and -5i
Step-by-step explanation:
Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function
The given equation is [tex]x^2+25 =0[/tex]
This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots
[tex]x^2 = -25 \\x = \sqrt{-25} \\x= \sqrt{-1}* \sqrt{25}\\[/tex]
[tex]x = i\sqrt{25}[/tex]
x = ± 5i
It will be false to say that -5i will be the only complex root to this equation.
The given equation will have +5i and -5i as its roots.
Lets verify
x = +5i
[tex](5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25\\-25 + 25 = 0[/tex]
x = -5i
[tex](-5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25 \\-25 + 25 \\ = 0[/tex]

If 65% of a number is 169 and 15% of the same number is 39, find 80% of that number.
Answer:
208
Step-by-step explanation:
169/65%=260= the original number
260 x 80% = 208
Answer:
208 is 80% of that number
Step-by-step explanation:
to find the number, take 65/100 (or 65%), and set it equal to 169/x (because x is the number that 169 is 65% of, so we need to find x)=> 65/100=169/x
Next, cross multiply to get 16900=65x
Divide both sides of the equation by 65 to get 260=x, which means that 260 is the mystery number that the question speaks of. Then, to get 80% of 260, set 80/100 equal to x/260=> 80/100=x/260
cross multiply to get 20800=100x
divide both sides by 100 to get 208
Therefore, the answer is 208
Kamal got married 5 years ago. Today his age is 1 1/4 times his age at the time of marriage. His sons age is 1/10 times his present age. What is hisson's age ?
Answer:Son's age =2.5 years old
Step-by-step explanation:
Step 1
Let the age of Kamla at marriage be represented as x
Age after five years = x+5
Given that today his age is 1 1/4 times his age at marriage, Our equation to express his age at marriage will be
x+ 5= (5/4)x
Multiplying 4 by both sides gives
4(x+5) = (5/4 x 4 )x
4x+20 = 5x
20=5x-4x
x= 20 years at Marriage
Therefore his present age = 20+5= 25
Step 2
Son' s age = 1/10 times his present age
Son's age = 1/10 x 25= 2.5 years old
