Un buzo profesional está explorando el fondo marino a 48 metros bajo el nivel del mar (−48 m). Al volver a la superficie del mar

Maru [420]

Respuesta:

31 minutos para llegar a la superficie del mar.

Explicación paso a paso:

Dado que :

Profundidad inicial = 48 m

8 metros = 1 minuto

Tiempo de parada por cada minuto de nado vertical = 5 minutos

Por lo tanto,

1 minuto = (48 - 8) = 40 metros

Tiempo de parada = 5 minutos

1 minuto = (40 - 8) = 32 metros

Tiempo de parada = 5 minutos

1 minuto = (32 - 8) = 24 m

Tiempo de parada = 5 minutos

1 minuto = (24 - 8) = 16 m

Tiempo de parada = 5 minutos

1 minuto = (16 - 8) = 8 m

Tiempo de parada = 5 minutos

1 minuto = 8 - 8 = 0 (superficie del mar)

(1 * 6) minuto + (5 * 5) minuto

6 + 25 = 31 minutos

31 minutos para llegar a la superficie.

The backgrounds on three computer screens are set to change after a specified amount of time, as

KengaRu [80]

Answer:

-6 7/hr= -6F per hour

Step-by-step explanation:

a rate of change can be defined as:

R=(total change in some quantity) (time in which the change happened)

In this case we know that the temperature dropped -30F in a given time, then we already know that:

Total change in some quanity =-30F now we know that this change took place between the 1:00pm and the 7:00 pm the total amount of ime between these two hours is:

T= (7.00 - 1.00 hr)= 6.00 hr

this means that the change happened =6 hours.

then we can replace these values in the above equation to get:

R=(-30F)/(6hr)=-6F/hr

this means that for each hours that passes the temperature decreases 6F

we also can write that this rate as:

R=-6F/HR =-6F per hour.

Paul sketched a right angel with legs of length a, b, and h. Then he writes an expression for the length of the hypotensure. Wha

MA_775_DIABLO [31]

Answer:

Paul might have written the expression $h^2=a^2+b^2$ .

Step-by-step explanation:

Given:

Length of the leg 1 = a

Length of the leg 2 = b

Hypotenuse = h

We need the expression Paul has written:

Solution:

Now we know that;

The figure sketched by Paul is a right angle triangle.

Now by Pythagoras Theorem which states that;

"The square of the length of the hypotenuse is equal to sum of the square of the length of the legs."

equation can be framed as;

$h^2=a^2+b^2$

Hence Paul might have written the expression $h^2=a^2+b^2$ .
