Which explains how to find the quotient of the division below? Negative 3 and one-third divided by StartFraction 4 over 9 EndFraction Write Negative 3 and one-third as Negative StartFraction 13 over 3 EndFraction, and find the reciprocal of StartFraction 4 over 9 EndFraction as StartFraction 9 over 4 EndFraction. Then, rewrite Negative 3 and one-third divided by StartFraction 4 over 9 EndFraction as Negative StartFraction 13 over 3 EndFraction times StartFraction 9 over 4 EndFraction. The quotient is Negative 9 and three-fourths. Write Negative 3 and one-third as Negative StartFraction 10 over 3 EndFraction, and find the reciprocal of StartFraction 4 over 9 EndFraction as StartFraction 9 over 4 EndFraction. Then, rewrite Negative 3 and one-third divided by StartFraction 4 over 9 EndFraction as Negative StartFraction 10 over 3 EndFraction times StartFraction 9 over 4 EndFraction. The quotient is Negative 7 and StartFraction 6 over 12 EndFraction = Negative 7 and one-half. Write Negative 3 and one-third as Negative StartFraction 9 over 3 EndFraction. Then, rewrite Negative 3 and one-third divided by StartFraction 4 over 9 EndFraction as Negative StartFraction 9 over 3 EndFraction times StartFraction 4 over 9 EndFraction. The quotient is Negative 1 and one-third. Write Negative 3 and one-third as Negative StartFraction 10 over 3 EndFraction. Then, rewrite Negative 3 and one-third divided by StartFraction 4 over 9 EndFraction as Negative StartFraction 10 over 3 EndFraction times StartFraction 4 over 9 EndFraction. The quotient is Negative 1 and StartFraction 13 over 27 EndFraction = Negative 1 and StartFraction 13 over 27 EndFraction.

Dr. Karuza would like to send some classes on a trip to Disneyland. She explains that in order for any classses to go, 25% of the passengers must be teachers. Aniyah explains that if 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.
Do you agree or disagree with her answer?
Answer:
No, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.
Step-by-step explanation:
Given: If 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.
To find: if the given statement is correct or not
Solution:
Total number of teachers = 4
Total number of students = 24
Total number of passengers = Total number of teachers + Total number of students = 4 + 24 = 28
Here,
25% of Total number of passengers = [tex]\frac{25}{100}(28)=7\neq 4[/tex]
So, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.
Find the volume of the rectangular prism. Express your answer as a simplified mixed number.
Answer:
414 9/16 m³
[tex]414\frac{9}{16}m^{3}[/tex]
Step-by-step explanation:
The volume of a Rectangular prism is calculated as Length × Width × Height
From the attached diagram,we can see that
The length = 8 3/8 m
The width = 6 m
The height =8 1/4 m
Converting the mixed fraction to improper fraction in other to simplify it better
The length = 67/8 m
The height = 33/4 m
The volume of the rectangular prism =
67/8 m × 6m × 33/4m
= (13266/32)m³
= 6633/16 m³
= 414 9/16 m³
= [tex]414\frac{9}{16}m^{3}[/tex]

The first three towers in a sequence are shown. The nth tower is formed by stacking n blocks on top of an n times n square of blocks. How many blocks are in the 99th tower?
Answer:
The 99th tower contains 9900 blocks.
Step-by-step explanation:
From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:
n + n²
Now let us use the diagram to validate the idea.
Tower 1:
n = 1
Number of blocks = 1 + 1² = 2
Tower 2:
Number of blocks = 2 + 2² = 6
Tower 3:
Number of blocks = 3 + 3² = 12
Using same idea, we can obtain the number of blocks in the 99th tower as follow:
Tower 99:
n = 99
Number of blocks = 99 + 99² = 9900
Therefore, the 99th tower contains 9900 blocks.

Answer:
x = 2, x = 9
Step-by-step explanation:
Given
x² - 11x + 18 = 0
Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)
The factors are - 9 and - 2 , since
- 9 × - 2 = + 18 and - 9 - 2 = - 11 , thus
(x - 9)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2 ← lesser value
x - 9 = 0 ⇒ x = 9 ← greater value

Krutika and Natasha are marking exam papers. Each set takes Krutika 72 minutes and Natasha 1 hour. Express the times Krutika and Natasha take as a ratio. Give your answer in its simplest form.
Answer:
6 : 5
Step-by-step explanation:
Each set takes Krutika 72 minutes.
Each set takes Natasha 1 hour.
Let us convert that to minutes:
1 hour = 60 minutes
Therefore, expressing the times it takes Krutika and Natasha as a ratio:
72 : 60
Divide by 6
12 : 10
Divide by 2
6 : 5
The ratio is 6 : 5

A sports club charges an initiation fee and a monthly fee. At the end of the 5 months, a member had paid a total of $450. At the end of the 10 months, she had paid a total of $500.
a) Write a linear system to model the situation
b) Solve the linear system by substitution to solve the related problem: What are the initiation fee and the monthly fee?
Answer:Initiation fee is $400 while monthly fee is $10
Step-by-step explanation:
Let the initial fee be x which is fixed while the monthly fee be y
At the end of 5 months, 450 was paid
This means that;
x + 5y = 450 ••••••••(i)
At the end of 10 months, $500 was paid
Mathematically, this means that;
x + 10y = 500•••••••••••(ii)
now we solve both equations simultaneously to get the value of x and y
our equation ii can be rewritten as;
x + 5y + 5y = 500
we can now insert equation i directly into this
450 + 5y = 500
5y = 500-450
5y = 50
y = 50/5
y = $10
From x + 5y = 450
let’s insert the calculated value of y
x + 5(10) = 450
x + 50 = 450
x = 450-50
x = $400

Which class interval contains the median?
Select your answer.
osh <10 10 sh< 20 20 sh < 30 30 sh<40
А
B
C
D
Answer:
2,8,8
Step-by-step explanation:
The class interval 20 <h < 30 contains the median.
Median :To find the interval in which median is lies, first we have to find the cumulative frequency.
The table is,
Height range frequency Cumulative frequency
0<h < 10 1 1
10 <h < 20 9 1 + 9 = 10
20 <h < 30 7 10 + 7 = 17
30 <h < 40 13 17 + 13 = 30
Sum = 30
Since, the sum of frequency is even. So that the median is ,
[tex]\frac{\frac{n}{2} th +(\frac{n}{2} +1)th}{2} =\frac{15th +16th}{2}[/tex]
From observing table, 15th and 16th term lies in cumulative frequency of 17.
Thus, the class interval 20 <h < 30 contains the median.

Answer:
f = 6, g = 8
Step-by-step explanation:
The area of Δ ADE = 60 - 48 = 12 cm²
Thus
[tex]\frac{1}{2}[/tex] AD × 4 = 12, that is
2AD = 12 ( divide both sides by 2 )
AD = 6 = f
The area of ABCD = 48 cm² , thus
fg = 48 , that is
6g = 48 ( divide both sides by 6 )
g = 8
Thus f = 6 and g = 8

Answer:
-21. -19.-17
Step-by-step explanation:
Let x be the smallest
x+2 next smallest
x+4 be the largest
4*(x) = 18+6(x+4)
Distribute
4x = 18+6x+24
Combine like terms
4x = 42+6x
Subtract 6x from each side
-2x = 42
Divide by -2
-2x/-2 = 42/-2
x = -21
x+2 = -19
x+4 = -17
Answer:
- 21, - 19, - 17
Step-by-step explanation:
Let y be the smallest no.
& y + 2 next smallest no.
& y + 4 be the largest no.
= 4 * (y) = 18 + 6 * (y + 4)
4y = 18 + 6y + 24
4y - 6y = 42
- 2y = 42
= - 21
The other 2 numbers are:
y + 2
= - 19
y + 4

La mama de maximo le pidio que fuera a la tienda dijo que comprara 0.5 litros de leche, el dueño de la tienda le dijo que solo tenia leche en envases de ½ litros ¿Es mas, menos o igual a la capacidad que le pidió su mama?
Answer:
1/2 litros es igual a la capacidad que le pidió su mamá.
Step-by-step explanation:
Para encontrar la respuesta debes escribir 0.5 como fracción. Para hacerlo, el numerador es el número original sin el punto decimal y para definir el denominador debes determinar cuántos digitos decimales tienes. En este caso, el número tiene un dígito decimal, por lo cual el denominador es 10. De acuerdo a esto:
0.5 se escribiría como [tex]\frac{5}{10}[/tex] y esta fracción se puede simplificar porque los dos números son divisibles entre 5:
5/5= 1
10/5= 2
Por esto, 0.5= [tex]\frac{1}{2}[/tex]
Esto significa que 1/2 litros es igual a la capacidad que le pidió su mama.
