The value of the expression b²/c² is 46656.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
We can use the given equations to express a, b, c, and d in terms of k:
a/b = b/c = c/d = k
From a/d = 1/216,
we have:
a/d = k² / (c/d)
Substituting k = b/c and simplifying:
a/d = (b/c)² / (c/d)
a/d = b² / (c² x d)
Multiplying both sides by c².
(a/d) x c² = b² / d
Substituting k = c/d:
(a/d) x c² = b² / k
Substituting a/b = k and solving for b²/c².
a/b = k
a = k x b
b = a/k
b² = a²/k²
(b²/c²) = (a²/k²) / (a²/k² x (d/c)²)
(b²/c²) = 1 / (d²/k²)
Substituting k = c/d and simplifying:
(b²/c²) = d²
Substituting a/d = 1/216:
(b²/c²) = (216²)
Therefore,
The value of the expression b²/c² is 46656.

The tins of cat food that I buy are normally 80 cents each. They are also available in packs of 6, but there is no advantage to this as they cost $4.80 My neighbor told me this morning that the everlo supermarket has a special offer this week: 25% off all tins and a further 60 cents off a pack of 6. I have given my son $20 and sent him to Everlo to but as many tins as he can.
Answers
Answer: 39 tins of cat food.
Step-by-step explanation:
I am assuming the question is how the number of tins that can be bought.
Step 1 - Discounted price
With the discount a tin would cost;
= 80 * ( 1 - 25%)
= 60 cents
Step 2 - Packs of 6 purchased at discounted price
Every pack of 6 attracts 60 cents off which means that they are paying the price of 5 tins for 6 tins.
Price of 5 tins;
= 60 * 5
= $3
Out of $20, the number of packs of 6 he can buy are;
= 20/ 3
= 6.67
= 6 packs of 6
Step 3 - Number tins not in pack of 6 bought
If he buys 6 packs of 6 the amount of money left is;
= 20 - ( 6 * 3)
= $2
With these $2, he could buy;
= 200 cents/60 cents
= 3.333
= 3 tins
Step 4 - Total number of Tins bought
The total number of tins he can buy are therefore;
= 6 packs of 6 + 3 tins
= (6 * 6) + 3
= 39 tins of cat food.

Tres hermanos pintarán la fachada de su casa. Alejandro pinta

8
de la casa durante el primer día.
Alberto pinta
4
9
de la casa durante el segundo día. Para el tercer día, Alan debe pintar lo que queda.
¿Qué porción de la casa le corresponde pintar a Alan?
Answers
Answer:
La porción de la casa que le corresponde pintar a Alan es [tex]\frac{13}{72}[/tex]
Step-by-step explanation:
Sabes que Alejandro pinta 3/8 de la casa durante el primer día, mientras que Alberto pinta 4/9 de la casa durante el segundo día. Entonces, la porción pintada de la casa durante esos dos días es la suma entre la porción pintada por Alejandro y la porción pintada por Alberto:
[tex]\frac{3}{8} +\frac{4}{9}[/tex]
Un método para sumar fracciones con distinto denominador consiste en buscar el común denominador de las fracciones que se van a sumar. Para ello se multiplica los denominadores de las fracciones: 8*9= 72. El común denominador se divide entre el denominador de la primera fracción. El resultado de la división se multiplica por el numerador de la misma fracción. Una vez que se divide y se multiplica, el resultado se coloca en el numerador con el signo correspondiente. Se realiza el mismo procedimiento con la otra fracción y se realiza la suma con los numeradores resultantes.
Entonces, en este caso se obtiene:
[tex]\frac{3}{8} +\frac{4}{9}=\frac{27+32}{72} =\frac{59}{72}[/tex]
Entonces, para calcular la porción de la casa que le corresponde pintar a Alan, y considerando que 1 representa un entero, la totalidad de la casa que se desea pintar, se realiza la resta entre la totalidad de la fachada a pintar y la porción pintada por Alejandro y Alberto:
[tex]1-\frac{59}{72}[/tex]
Considerando que el procedimiento de la resta es similar a la suma, se obtiene:
[tex]1-\frac{59}{72}=\frac{72-59}{72} =\frac{13}{72}[/tex]
La porción de la casa que le corresponde pintar a Alan es [tex]\frac{13}{72}[/tex]

The local cable company charges $90 per month for basic cable and $12 per month
for each additional premium cable channel. The function cx x ( ) = + 90 12 represents
the monthly charge (in dollars), where x represents the number of additional premium
channels. How many additional premium channels would you have ordered if your bill
was $114 per month?
Answers
Answer:
Two additional premium channels were ordered
Step-by-step explanation:
Linear Modeling
It consists of describing a real situation with a mathematical function that corresponds to a straight line.
An example is the described situation where the cable company charges $90 per month for basic cable and $12 for each additional premium cable channel.
The linear model for the charges of the company is:
c(x) = 90 + 12x
Where x is the number of additional premium channels.
Knowing that one month the charge was $114, we can find x:
114 = 90 + 12x
Subtracting 90:
114 - 90 = 12x =24
Dividing by 12:
x = 24/12
x = 2
Two additional premium channels were ordered

= 30,350
For greater number
_x10^blank - _ x 10^_
8x(10)^9 - 2 x (10)^1 ( we use 9 as the power because greater number used as power gives the bigger number and the next smaller number 8 as base. Similarly we use smaller number for power to get a smaller for the greatest difference)
= 8,000,000,000 -20

For smaller number
_x10^blank - _ x 10^_
1x(10)^3 - 9 x (10)^2 ( we use 3 as the power because smaller number used as power gives the smaller number and the next smallest number 1 as base. Similarly we use next smaller number for power to get the next smaller for the smallest difference)

the population of a country in 2009 was 642000 and it was increased by 5 % in 2010.
i-Find increase in population.
ii-How much was the population in 2010.
iii-Find percentage of increase over the population of 2009
Answers
Answer:
i) 32100 people
ii) 674100
iii) 5%
Step-by-step explanation:
The population in 2009 was : 642,000
The percent increase was by : 5%
This means the population in 2010 will be :
105/100 * 642000 = 674,100
i) Increase in population is ; 674,100 - 642,000 = 32100 people
ii) The population in 2010 was : 674,100
iii) Population of 2009 = 642000
Population of 2010 = 674,100
Increase in population = 674,100 - 642000 = 32100
Percent increase = increase/ original population * 100
Percent of increase = 32100/642000 * 100 = 5%

Sarah started 3 miles below the rim of the canyon and hiked until she was 8 miles above the rim. Her brother Sam said she hiked 5 miles. Sarah said she hiked 11 miles.
Who is correct and why?
A. Sam is correct because |3 – 8| = 5.
B. Sam is correct because |–3 – 8| = 5.
C. Sarah is correct because |–3 + 8| = 11.
D. Sarah is correct because |–3 – 8| = 11.
Answers
Answer:
D
Step-by-step explanation:
We can assume that the rim of the canyon is 0. Sarah started 3 miles below, so -3, BUT distance can never be negative, so it's considered 3 miles. Then, she went 8 miles above zero. So the 3 miles she went before reaching the rim plus the 8 miles she went after reaching the rim equals 11 miles.
So now we know that Sarah is right, but how do we know which equation is correct? Well, if we look at option C:
[tex]|-3+8|=11[/tex]
When solving absolute value, we solve everything within the absolute value before applying the absolute value. This means that we add -3+8 first, which equals 5, and then apply absolute value, which still equals 5. This equation is not correct.
I hope this helps!
