For adults, there were 40 tickets sold, and for kids, there were 60 tickets sold.
What are the three algebraic rules?There are several laws that regulate the sequence in which you should do the operations in math and algebra. The Commutative, Associative, and Distributive Laws are the three that are most frequently discussed.
Let x be the total number of adult tickets sold.
6.50 × x + 2.50 × (100 - x) = 410
6.50 × x + 250 - 2.50x = 410
4x = 410 - 250
x = 40
Hence,
a) 40 tickets were sold by adults, according to item

¿Cuál de las figuras tiene ángulos agudos? A. El triángulo equilátero. B. El cuadrado. C. El pentágono regular. D. El heptágono regular.
Answer:
A. El triángulo equilátero.
Step-by-step explanation:
Un triángulo equilátero tiene ángulos agudos.
Los ángulos agudos tienen una medida de menos de 90 grados.
La suma de los ángulos del triángulo siempre debe ser igual a 180 grados.
Cuando 3 ángulos son iguales, la medida de cada uno de ellos vendrá dada por
3 veces = 180
x = 180/2 = 60 grados
La suma de los ángulos del cuadrado siempre es igual a 360 grados. Cuando 4 ángulos son iguales, la medida de cada uno de ellos vendrá dada por
4x = 360
x = 360/4 = 90 grados
Un cuadrado tiene cuatro ángulos rectos.
La suma de los ángulos del pentágono siempre es igual a 540 grados. Cuando 5 ángulos son iguales, la medida de cada uno de ellos vendrá dada por
5 veces = 540
x = 540/5 = 108 grados
Un pentágono regular tiene 5 ángulos obtusos.
La suma de los ángulos interiores del heptágono siempre es igual a 900 grados. Cuando 7 ángulos son iguales, la medida de cada uno de ellos vendrá dada por
7x = 900
x = 900/7 = 128,57 grados
Un heptágono regular tiene 7 ángulos obtusos.
Entonces, solo el triángulo equlateral tiene ángulos agudos.
English
An equilateral triangle has acute angles.
Acute angles are having measurement less than 90 degrees.
The sum of angles of the triangle must always be equal to 180 degrees.
When 3 angles are equal then the measure of each of them will be given by
3x= 180
x= 180/2= 60 degrees
The sum of angles of square always equal 360 degrees. When 4 angles are equal then the measure of each of them will be given by
4x= 360
x= 360/4= 90 degrees
A square has four right angles.
The sum of angles of pentagon always equal 540 degrees. When 5 angles are equal then the measure of each of them will be given by
5x= 540
x= 540/5= 108 degrees
A regular pentagon has 5 obtuse angles.
The sum of interior angles of heptagon always equal 900 degrees. When 7 angles are equal then the measure of each of them will be given by
7x= 900
x= 900/7= 128.57 degrees
A regular heptagon has 7 obtuse angles.
So only equilateral triangle has acute angles.

auggie bought 8 books. Some books cost $13 each and the rest of the books cost $24 each. They spent a total of $159. Write a system of linear equations that could represent the given situation
Answer: Let x be the number of $13 books that Auggie bought and y be the number of $24 books. Then we can represent the given information in the following system of linear equations:
x + y = 8 (the total number of books Auggie bought is 8)
13x + 24y = 159 (the total amount of money Auggie spent is $159)
This system of linear equations represents the given situation. We can use this system to find out how many books Auggie bought of each price by solving the system of equations.
The equation (1) represents the number of books that Auggie bought is 8, and equation (2) represents the amount of money he spent $159. This system of equations is a valid representation of the given situation because the values of x and y that satisfy the system of equations will be the number of $13 books and the number of $24 books that Auggie bought.

What is simple interest?A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,
$ 128,000 is the amount financed (P).
t = 15 years
The interest rate equals 5.05%.
Amount after 15 years equals,
A = [tex]P(1+\frac{r}{100}[/tex]
=128,000[tex](1+\frac{5.05}{100} )^{15}[/tex]
=268009
Rose and Andrew has taken four points to lower their rate to 4.81% .
A =128,000 [tex](1+\frac{4.81}{100} )^{15}[/tex]
A = 259,713
Cost of four points = 268,009.890 - 259,713.040 = $8296.8496
Hence, the cost of the four points will be $8296.8496

If the square base with perimeter 24 inches then the height of the right pyramid be 8.485 - inches.
What is meant by right pyramid?A right pyramid is one whose apex is located exactly above the centroid of the base. As a result, a right pyramid is a special instance of a regular pyramid.
It is referred to as the right pyramid if the pyramid's apex lies immediately above the base's center. If not, the pyramid is known as the oblique pyramid.
A right-triangular pyramid is a three-dimensional object that has a base that is a right-angle triangle and extends up to a single point.
Right pyramids have apex points that are immediately above the centroid of their base. Oblique pyramids are referred to as non right pyramids. An implied right pyramid is a regular pyramid since it has a regular polygon base.
24 / 4 = 6 inches - the edge length of the square base
9² = 3² + Height²
simplifying the above equation, we get
Height² = 9² - 3²
Height² = 72 take the square root of both sides

(a) Express its value, in RM, after n years.
(b) Hence, find its value after 10 years to the nearest ringgit.
Answer:
Step-by-step explanation:
Depreciation means wearing and tearing in the value of an asset over the years
(a) Given:
p = initial value of an asset
i% = depreciation per year
n = number of years
Depreciation after n years (d) = [tex]p(1-\frac{1}{100} )^{n}[/tex]
Value of machine after n years = p-d
(b) Given:
p = RM100000
i% = 5
n = 10
Depreciation after 10 years = [tex]100000(1-\frac{5}{100} )^{10} = 59873.69392[/tex]
Value of machine after 10 years = p-d = RM100000 - RM59873.69392 = RM 40123.30608

I want to install carpet in my living room, which is 200 inches long and 50 ft wide. The carpet is sold for 5000 naira per yard2. How much will I pay?
Answer:
462962.96 naira
Step-by-step explanation:
This problem is complicated by the use of two different units. I chose to use inches for the dimensions of the carpet.
200 in long
50 ft wide = 50 x 12 = 600 in.
Area = 200 x 600 = 120000 in^2
A square yard is a square 36 in. x 36 in. = 1296 in^2
Divide 120000 by 1296 to find out how many square yards of carpet you'll need.
120000 / 1296 = 92.59

The distance Issa travelled from school to his house is 9.6 km.
What is the distance travelled?The actual length covered by the body is defined as distance travelled, whereas displacement is the straight path between the initial and final points.
Here,
Let the total distance between school and home be 'x' meters.
Issa jogged two-thirds of x = 2x/3
So the total distance between school and home is = 2x/3 + 3200
However, the total distance from school to home = x
= 2x/3 + 3200 = x
= 3200 = x/3
= 9600 = x
As a result, the total distance from school to home is 9600 meters.
We're now converting it to kilometers.
We know that 1000 meters equals one kilometer.
9600 meters = 1/1000 x 9600
= 9.6 kilometers
Therefore the distance travelled will be 9.6 km.
