A circle graph also known as a pie chart is used to represent data graphically. the circle graph is made up of a circle that is divided into quadrants. Each quadrants represents different classifications of data and the proportion of each classification.
the sum of angles in a pie chart is 360 degrees while the total percentages is 100%.
If there are 25% of the students in a class each take maths, physics , biology and chemistry, the pie chart would be divided into 4 quadrants with each quadrant measuring 25%
Write a quadratic equation in standard form that has the following solutions: x = 4/3 and x = - 2/5
Answer:
15x^2 - 14x - 8 = 0.
Step-by-step explanation:
(x - 4/3)(x + 2/5) = 0
Converted to integer values by multiplying the first bracket by 3 and the second by 5:
(3x - 4)(5x + 2) = 0
Expanding the brackets:
15x^2 + 6x - 20x - 8 = 0
15x^2 - 14x - 8 = 0.

Elisa y su sombra forman un ángulo recto . La sombra anide 1,2 m y el ángulo con el que se ve la parte superior de su cabeza desde el extremo de la sombra mide 54° 50° . Calcular la altura de Elisa
Answer:
h = 1.65 m
Step-by-step explanation:
Me parece que el problema está mal formulado por lo siguiente:
El angulo al que se refiere el problema es 54° o es 50° o es 54°,50´
Como resolver el problema en cualquier caso.
Si Elisa y su sombra forman un angulo recto, entonces Elisa, su sombra y la distancia entre la cabeza de Eliza y el final de su sombra forman un triangulo rectangulo. Para el cual entonces solo es necesario buscar la tangente del angulo ( cateto opuesto sobre cateto adyacente) como conocemos el cateto adyacente ( la sombra de Elisa ) calculamos la altura de Elisa (h).
Asumamos que el angulo es de 54° entonces
tang 54° = 1.3763
tang 54° = 1.3763 = h/1.2
h = 1,3763*1,2 m
h = 1.65 m
De igual manera se procedería si el angulo es de 50° ( en este caso la tang 50° = 1.1917

Step-by-step explanation:
a + c = 5
9a + 4c = 30
let a = 5-c
substitute:
9(5-c) + 4c = 30
45 - 9c + 4c = 30
45 - 5c = 30
-5c = -15
c = 3
a = 2
