Competencia a evaluar: Usa el concepto de semejanza para resolver triángulos. En un triángulo rectángulo ABC de catetos AB=12cm y AC=16cm se traza DE= 4cm perpendicular a la hipotenusa (con D sobre la hipotenusa y E sobre AC). Calcular las medidas de todos los lados de los triángulos ABC y CDE, usando solo el concepto de semejanza (plantee las ecuaciones o justifique sus respuestas usando solo semejanza).

a 10 percent increase

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

step-by-step explanation:

abc

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
