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

Answer:

8x(10)^9 - 2 x (10)^1

1x(10)^3 - 9 x (10)^2

Step-by-step explanation:

3.1 X (10)^4- 6.5 X (10)^2

= 31000- 650

= 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

= 7,999,999,980

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)

= 1000- 900

= 100

We fill in the blanks keeping in mind that we do not have to repeat the numbers from 1-9 and also the numbers should have such an arrangement that they show the smallest and largest possible differences.

Tres hermanos pintarán la fachada de su casa. Alejandro pinta
3
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 answer will be 150 (D)

You add 33 and 117 which gives you 150. Subtract 180 from the 150 which will give you 30. The 30 is for >c.
Then you add 33+117+30 giving you 180 that’s the whole inside. Now that you have the missing angle degree (30) you subtract the 30 from 180. Giving you 150 for I Hope this makes sense I apologize if it doesn’t.

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.

A bakery has 72 half gallons of milk. It takes 1 2/3 cups of milk to make a cake. Note that 1/8 half gallon=0.125 half gallon. How many cakes can the bakery make?

Answers

Answer:

The total cake make in the bakery ≅ 346 cakes

Step-by-step explanation:

Given that:

A bakery has 72 half gallons of milk

It takes [tex]1\dfrac{2}{3}[/tex] cups of milk to make the cake ;

i.e. [tex]\dfrac{5}{3}[/tex] cups of milk to make the cake after we converted the mixed fraction to an improper fraction.

Also,1 cup =  [tex]\dfrac{1}{8}[/tex] half gallons = 0.125 half gallons

Thus, the amount of milk required to make the cake = [tex]\dfrac{1}{8} \times \dfrac{5}{3}[/tex]

[tex]= 0.125 \times \dfrac{5}{3}[/tex]

= 0.208

The total cake make in the bakery = [tex]\dfrac{72}{0.208}[/tex]

The total cake make in the bakery = 346.15

The total cake make in the bakery ≅ 346 cakes
