Answer:
an integer is a rational number sometimes(eg.17=17/1) but not always.
a rational number can be written in the form p/q where p and q are integers.
Step-by-step explanation:
Answer:
a) $654
b) 27 unidades cuadradas
c) 721
Step-by-step explanation:
a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?
Una docena = 12
Por eso:
12 bolígrafos = $ 7848
1 bolígrafo = $ x
Cruz multiplicar
12 bolígrafos × $ x = 1 bolígrafo × $ 7848
$ x = 1 bolígrafo × $ 7848/12
$ x = $654
b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?
Área de un triángulo =
= 1/2 × Base × Altura
1/2 × 9 × 6
= 27 unidades cuadradas
c) Cien veces la suma de 4.5 con 2.71
Esto se calcula como:
100 × (4,5 + 2,71)
= 100 × (7.21)
= 721

<h3> What is the polar equation?</h3>
A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.
From the equation, we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally, the polar equation for e = 1 and y = + c is mathematically represented as
Therefore the polar equation will be

Answer:
325
Step-by-step explanation:
Total Tickets = 585
Let the adult tickets be = x
If 65 fewer student tickets were sold than adult tickets then Student tickets = x-65
Student Tickets + Adult Tickets = 585
x + (x-65) = 585
x + x - 65 = 585
2x - 65 = 585
2x = 585 + 65
2x = 650
2x/2 = 650/2
x = 325

Given:
A quadrilateral WXYZ has vertices W(3, −5), X(1, −3), Y(−1, −5), and Z(1,−7).
Rule of rotation is 
.
To find:
The vertices after rotation.
Solution:
We know that, means 90 degrees counterclockwise rotation around the origin.
So, the rule of rotation is defined as
Using this rule, we get
Therefore, the required vertices after rotation are W'(5,3), X'(3,1),Y'(5,-1) and Z'(7,1).
