Answer: 170 people paid GH¢20 and 180 people paid GH¢30
Step-by-step explanation:
Let the number of people that paid GH¢20 be represented by x.
Let the number of people that paid GH¢30 be represented by y.
Based on the above information given, we can form an equation which will be:
x + y = 350 ....... i
20x + 30y = 8800 ....... ii
Multiply equation i by 20
20x + 20y = 7000 ...... iii
20x + 30y = 8800 ...... iv
Subtract iii from iv
10y = 1800
y = 1800/10
y = 180
Since x + y = 350
x = 350 - y.
x = 350 - 180
x = 170
Therefore, 170 people paid GH¢20 and 180 people paid GH¢30

Five times of a number divided by 7 more than the number.If the result is 2 then what is the orignal number.
Answer:
n = 14/3 or 4 2/3
Step-by-step explanation:
n = a number
5n/(7+n) = 2
cross-multiply to get:
5n = 2(7+n)
5n = 14 + 2n
3n = 14
n = 14/3 or 4 2/3

f(x)=2^x is the function to calculate the number of sections there will be when a paper is folded x times. What is the average rate of change in the number of sections based on the number of folds in the interval [3,6]?
PLEASE READ THIS EXPLANATION: It is an EXTREMELY foundational concept in algebra that must be understood. Ask questions in the comments if you do not understand anything because I love helping others learn! Do not be shy. :)
Alright, so let's just understand the problem. The interval [3,6] means that the smallest x-value is x=3 and the largest x-value is x=6, and they both INCLUDE x=3 and x=6 (It would exclude x=3 and x=6 if it was like interval (3,6) with parentheses). Since f(x) is an exponential function, the change per x is not consistent and its growth actually grows as it continues in the direction of infinity, so that is why the average rate of change is interesting and very much relies on what range there is. The average rate of change from x=3 to x=6 will be far smaller than the average rate of change farther down the road at x = 99999 and x = 100003.
So, how do we find the average rate of change? All you have to do is find the slope between two points. Simple as that.
So, how do we apply that here? Imagine a graph with two points, one point at x = 3 and one point at x = 6 and we do not know the y-value of either of these points. So, that's our first step!
We need to first find how much it grows at x=3 and x=6 separately to find the the y-value of these points. f(x) = 2^x for x = 3 means y = 8, and f(x) = 2^x for x = 6 means y = 64. We now have two points:
(3, 8) and (6, 64)
Now, all we have to do is find the slope between these lines. All we have to do is use the normal formula for finding slope:
(y₂ - y₁) / (x₂ - x₁) OR (y₁ - y₂) / (x₁ - x₂)
Most people use the first one, but they give you the exact same answer, so don't ever think it's impossible to use the second one. Let's just use the first formula anyway.
(3, 8) = (x₁, y₁)
(6, 64) = (x₂, y₂)
Now, let's use the formula (remember you can use either one because it won't affect your answer):
(y₂ - y₁) / (x₂ - x₁) = (64 - 8) / (6 - 3) = 56 / 3 = 18 and 2/3
So, the average rate of change is 18 and 2/3 or 18.666666667.
Para la actuacion del dia de la madre , se colocaron en el patio 40 filas de 32 asientos para cada una. Para la siguiente actuacion,quieren acomodarla mismas cantidad de asientospero esta vez en 64 o en 60 filas ¿como seria la distribucion
Answer:
En 64 filas habrá 51 asientos
en 60 filas habrá 48 asientos
Step-by-step explanation:
Spanish
Primero se averigua la relación entre las filas y los asientos.
40: 32
Dividiendo por 8
5: 4
Usando esta relación podemos encontrar el número de asientos en el número dado de filas.
Si el número de filas es 64 entonces
Asientos de filas
64 x
5 4
Uso de la regla de productos cruzados
x = 64 * 4/5 = 51,2
En 64 filas habrá 51 asientos
Si el número de filas es 60 entonces
Asientos de filas
60 x
5 4
Uso de la regla de productos cruzados
x = 60 * 4/5 = 48
en 60 filas habrá 48 asientos
English
First the ratio of the rows to the seats is found out
40 : 32
Dividing by 8
5: 4
Using this ratio we can find the number of seats in the given number of rows.
If the number of rows is 64 then
Rows seats
64 x
5 4
Using cross product rule
x= 64*4/5= 51.2
In 64 rows there will be 51 seats
If the number of rows is 60 then
Rows seats
60 x
5 4
Using cross product rule
x= 60*4/5= 48
in 60 rows there will be 48 seats

20% of a is 11 what is a
Answer: 20% of 11 is 2.2
Step-by-step explanation:
Answer:
55
Step-by-step explanation:
To solve this set up a proportion. This proportion should be in part/whole form. This means to divide the part (aka 11) by the whole (aka the variable), additionally, 20% can be made into a fraction by dividing it by 100. So the proportion is [tex]\frac{20}{100} =\frac{11}{x}[/tex]. Then, cross multiply. Once this is done the new equation is [tex]20x=1100[/tex]. Next, divide both sides by 20. This gives you [tex]x=55[/tex], therefore 11 is 20% of 55.

Write your question here (Keep it simple and clear to get the best answer) If jun has 12 T-shirt 6 pairs of parts, and 3 pairs of share, how many possibilities can be'drace himself up for the day?
Answer:
the number of possibilities that can be drace himself up for the day is 216
Step-by-step explanation:
Given that
jun has 12 t-shirts,6 pairs of pants and 3 pairs of shoes
We need to find out the possibilities that can be drace himself up for the day
So here
[tex]= 12C_1 \times 6C_1 \times 3C_1\\\\= \frac{12!}{1!(12 - 1)!} \times \frac{6!}{1!(6 - 1)!} \times \frac{3!}{1!(3 - 1)!}\\\\= \frac{12!}{1!(11)!} \times \frac{6!}{1!(5)!} \times \frac{3!}{1!(2)!}\\\\= 12 \times 6 \times 3\\\\= 216[/tex]
Hence, the number of possibilities that can be drace himself up for the day is 216
