Rafiq compares the
expressions 4 X 8 and 8 X 12. He says that 8 is twice
as much as 4, so 4 X 8 must be twice as much as 8 X 12.
Correct his statement, and explain his error.
HELLLPPPPP
Answer:
Hey there!
Rafiq's error was that the other number is also changing. He had 4 x 8 and if he had 8 x 8, that would be twice as much, but he used 8 x 12 instead, and 12 is not 8.
Let me know if this helps :)
The other number that was also changing was Rafiq's mistake if Rafiq compares the expressions 4x8 and 8x12.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that are +, -, ×, and ÷.
It is given that:
Rafiq compares the expressions 4x8 and 8x12
The correct statement is for Rafiq compare the expressions 4 X 8 and 8 X 12
The fact that the other number was also changing was Rafiq's mistake.
Rafiq had 4 × 8, therefore 8 x 8 would have been twice as much; however, he utilized 8 x 12, even though 12 is not equal to 8.
Thus, the other number was also changing was Rafiq's mistake if Rafiq compares the expressions 4x8 and 8x12.

The formula D =3/2 (100 – C) relates D,
the temperature measured on the Delisle
scale, in degrees, and C, the temperature
measured on the Celsius scale, also in
degrees. What is the temperature in
degrees Celsius when the temperature in
degrees Delisle is 78°?
BO
Answer:33
Step-by-step explanation:
3/2 —> 1.5
1.5(100-C) C is 78°
1.5(100-78)
1.5(22)
33
The temperature in degrees Celsius, if the function of the relationship is given as 78 = 3/2(100 - C), is calculated as: C = 48
What is Function?A function is a form of equation that relates one quantity that changes with another.
Given the formula for the function representing the relationship between D and C as, D = 3/2(100 - C), to find the temperature in degrees Celsius when the D = 78, substitute D = 78 into D = 3/2(100 - C).
78 = 3/2(100 - C)
(2)(78) = 3(100 - C)
156 = 3(100 - C)
156/3 = 100 - C
52 = 100 - C
52 - 100 = -C
-48 = -C
C = 48

An airport offers 2 shuttles that run on different schedules. If both shuttles leave the airport at 4.00 pm at what time will they leave the airport together
Answer:
4:18 pm
Step-by-step explanation:
An airport offers 2 shuttles that run on different schedules.If both shuttles leave the airport at 4:00 p.m.,at what time will they next leave theairport together.
Shuttle A leaves every 6 minutes
Shuttle B leaves every 9 minutes
Solution
To solve for when next both shuttles will leave the airport together, find the least common multiples of 6 minutes and 9 minutes
Shuttle A (every 6 minutes) = 6, 12, 18, 24
Shuttle B (every 9 minutes) = 9, 18, 27, 36
The least common multiples of 6 minutes and 9 minutes is 18 minutes
4:00 pm + 18 minutes
= 4:18 pm
The next time both shuttles will leave theairport together is 4:18 pm of the same day

Chocolate ganache is made from chocolate and cream in a3:2 ratio, respectively. If one batch of ganache requires 240 grams of chocolate, how many grams of cream is required?
Answer:
160 grams
Step-by-step explanation:
Since one batch of ganache needs 240 grams of chocolate, you divide 240 by 3, since the ratio is 3:2.
240÷3x= 80.
Now that you have x, multiply x by 2.
80*2= 160
Rachel has 24 red candies and Maya has 18 green candies. They want to arrange the candies in such a way that each row contains equal number of candies and also each row should have only red candies or green candies. What is the greatest number of candies that can be arranged in each row?
Answer: 6 candies per row.
Step-by-step explanation:
The restrictions that we have are:
Each row has the same number of candies.
Each row has only one color of candy.
We want to find the largest possible rows.
We have 18 green candies and 24 red candies.
Now, to arrange them in rows of equal numbers, we should find a common factor between 18 and 24. (particularly, we want to find the largest common factor between 18 and 24).
Now, to find common factors we first take the smaller number, and we divide it by different numbers, starting by 2 (we want to divide by small numbers, so the result will be the largest factor)
18/2 = 9.
Now to see if 9 is also a factor of 24, we see if the quotient between 24 and 9 is a whole number.
24/9 = 2.66
This is not a whole number, so 9 is not a common factor.
Now we divide by the next number, 3.
18/3 = 6.
24/6 = 4.
So 6 is a common factor of 18 and 24.
Then each row will have 6 candy.
And we will have:
18/6 = 3 rows of green candy.
24/ = 4 rows of red candy.

A student has some $1 and $5 bills in his wallet. He has a total of 19 bills and that are worth $55. how many of each type of bill does he have
Answer:
y= 9 ( 5 dollars bill)
x=10 ( one dollar bill)
Step-by-step explanation:
let x be the one dollar bill and y the 5 dollar bill
x+y=19 ⇒ x=19-y
x+5y=55 ( solve by substitute x=19-y)
19-y+5y=55
4y=55-19
4y=36 ⇒ y=36/4
y= 9 ( 5 dollars bill)
x+y=19
x+9=19
x=19-9
x=10 ( one dollar bill)
check :
x+5y=55
10+5(9)=
10+45 = 55 dollars

What is the 8th term of this geometric sequence?
1, 3, 9, 27,...
Answer:
1*3*3*3*3*3*3=729. For each term you multiply the previous term by three.
Answer:
2187
Step-by-step explanation:
To find the 8th term, we can find and use the explicit formula.
The standard form of the explicit formula for a geometric sequence is:
[tex]x_n=a(r)^{n-1}[/tex]
Where a is the initial term, r is the common ratio, and n is the nth term.
From the sequence, we can see that the first term is 1, and each term is 3 times the previous term. Thus, the common ratio is 3.
Substituting these into our equation, we will have:
[tex]x_n=1(3)^{n-1}\\x_n=(3)^{n-1}[/tex]
So, to find the 8th term, substitute 8 for n:
[tex]x_8=(3)^{8-1}[/tex]
Subtract:
[tex]x_8=(3)^7[/tex]
Evaluate:
[tex]x_8=2187[/tex]
So, the 8th term is 2187.
And we're done!

The question is not clearly stated, below is the clearly stated question and answer:
A customer wants you to enlarge a photo to 2 3/4 its current height. The photo’s current height is 3 1/4 inches. What should its enlarged height be, in inches?
Answer:
[tex]Enlarged\ height = 8\frac{15}{16}\ inches[/tex]
Step-by-step explanation:
[tex]current\ height\ =\ 3\frac{1}{4} = \frac{13}{4} \\ magnification\ factor = 2\frac{3}{4} = \frac{11}{4} \\Magnification (enlargement)\ =\ (magnification\ factor) \times (current\ height)\\Magnification\ =\ \frac{11}{4} \times \frac{13}{4}\\ Magnification\ =\ \frac{143}{16}[/tex]
Next, we will concert from the improper fraction to a mixed fraction:
when 143 is divided by 16, there will be 8 whole numbers and a remainder of 15, hence, the mixed fraction is:
[tex]\frac{143}{16} = 8\frac{15}{16}[/tex] (Alternatively, a scientific calculator can be used)
Therefore, enlarged height [tex]= 8\frac{15}{16}\ inches[/tex]

Si para una receta de flan para 3 porciones se nesecita un cuarto de litro de leche . ¿ cuanta leche se nesitaria para preparar la receta para 9 personas ?
Answer:
Para preparar la receta de flan para 9 personas se necesita [tex]\frac{3}{4}[/tex] L de leche
Step-by-step explanation:
La regla de tres simple directa se utiliza cuando el problema trata de dos magnitudes directamente proporcionales, es decir, magnitudes que si al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida por ese número. Es decir, cuando una magnitud aumenta la otra también lo hace en la misma proporción, y si la magnitud disminuye la otra disminuirá de igual forma.
Conociendo 3 valores “a”, “b” y “c” y teniendo un valor incógnita que deseamos conocer, la regla de tres simple directa se aplica de la siguiente forma:
a ⇒ b
c ⇒ x
Entonces : [tex]x=\frac{c*b}{a}[/tex]
En este caso se aplica de la siguiente manera: considerando que cada persona recibe una porción, si para preparar la receta para 3 personas se necesita [tex]\frac{1}{4}[/tex] de litros de leche, para preparar la receta para 9 personas cuánta leche se necesita?
3 personas ⇒ [tex]\frac{1}{4}[/tex] L
9 personas ⇒ x
[tex]x=\frac{9 personas*\frac{1}{4} L}{3 personas}[/tex]
x= [tex]\frac{3}{4}[/tex] L
Para preparar la receta de flan para 9 personas se necesita [tex]\frac{3}{4}[/tex] L de leche
