350 people watched a beauty contest. Some paid GH¢20.00 each while others paid GH¢30.00 each. The total amount collected was GH¢8,800.00. Find how many paid the two different rates.
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

Hi! Answer this please!
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

On Friday, 153 people went to the movies in Smalltown. On Saturday and Sunday, 337 people went to the movies. On Friday and Saturday, 391 people went to the movies. How many people went to the movies on each day? Friday:. Saturday:. Sunday:
Answer:
Friday: 153 people Saturday: 238 Sunday: 99
Step-by-step explanation:
Subtract 153 from 391 to find the people on Saturday (238). Subtract 238 from 337 to find the people on Sunday (99).
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 26 inches, and the length of the base is 18 inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.
Answer:
if it was 29inches it would be 78.7
Step-by-step explanation:
The given altitude and the base length of the triangle can be used for
finding the lengths of the other two sides.
The perimeter of the triangle is approximately 73.0 inches
Reasons:
The altitude is the perpendicular bisector of the base of the triangle
Length of the altitude = 26 inches
Length of the base of the triangle, b = 18 inches
Required:
The perimeter of the triangle
Solution:
The base length of the two congruent triangles formed are [tex]\dfrac{18 \, cm}{2}[/tex] = 9 cm
each.
Therefore;
The length of the hypotenuse side, L, is given by Pythagoras's theorem as
follows;
L² = 9² + 26² = 757
The hypotenuse side, L = The length of the equal sides of the isosceles triangle
Therefore, the perimeter of the triangle, P = b + 2·L
Which gives;
To the nearest tenth, the perimeter of the triangle, P = 18 + 2·√(757) ≈ 73.0
The perimeter of the triangle, P ≈ 73.0 inches

Answer:
the number of possibilities that can be drace himself up for the day is 216
Step-by-step explanation:

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]

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.
