1. This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this composite figure? S
White raven [17]

Answer:

29.92 m² (nearest hundredth)

Step-by-step explanation:

\textsf{Area of a sector}=\dfrac{\theta}{360\textdegree}\pi r^2

\implies \textsf{area}=\dfrac{30}{360\textdegree}\pi \cdot 5.5^2=\dfrac{121}{48}\pi \textsf{  m}^2

Area of rectangle = width × length

⇒ area = 4 × 5.5 = 22 m²

Total area = area of sector + area of rectangle

⇒ total area = \dfrac{121}{48}\pi +22 = 29.91943148... = 29.92 m² (nearest hundredth)

PLEASE CAN SOMEONE HELP ASAP!!!!!!!!<br> DUE BY 11:59 OMGGG
Vaselesa [24]

Answer:

A, C, F

Step-by-step explanation:

JK is proportional to PQ, so that would be 8/x. Then, JL is proportional to PR, which would be 10/5. So, the answer is: 8/x = 10/5

Then, C would also be correct as KL is proportional to QR, and JK is proportional to PQ.

Finally, F is correct as JK to KL is proportional to PQ to QR, as JK is proportional to PQ, and KL is proportional to QR.

1. Una escalera de 4 m de longitud se apoya sobre una pared vertical. Si la distancia entre la base de la escalera a la pared es
enot [183]

Answer:

puedes resolver de dos maneras si diste teorema de Pitágoras lo aplicas

hipotenusa al cuadrado = cateto 2 +cateto 2 ( el 2 significa al cuadrado)

sustituyes

hipotenusa= 4m

cateto= 2,5

hay que hallar el otro cateto que nos daría la altura a la que está la escalera

despejamos y tenemos

cateto 2= hip2 -cat2

cat2=(4)2-(2,5)2=

       =   16-6,25=9,75

luego hallamos la raíz cuadrada de 9,75= 3,12

     

la altura a la que se encuentra es 3,12m

-si aun no diste Pitágoras podes representarlo en una hoja utilizando cm en lugar de metros( a escala). trazas el triángulo rectángulo la base te la da la distancia a la cual se encuentra la escalera de la pared es decir 2,5cm trazas la hipotenusa de 4cm de manera que coincida con el cateto opuesto , y mides el valor de este ,será de 3,12cm no olvides que la respuesta la debes dar en metros ya que es la unidad de medida que te da.

A cell phone company charges a monthly fee of $35 and an addition $0.20 per minute used.
kiruha [24]

Answer:

35 + .2m

Step-by-step explanation:

The monthly fee of $35 is a base pay, and you don't change anything with it.

The "m" stands for minute, and since it costs $.20 for each minute, multiply the two together to get that part of the equation.
