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?
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

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?
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

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?
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 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
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%

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.

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.
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.
