Can somebody help me out please !
Agata [3.3K]

Answer:

Part A

5yr old boy.

Y=-(1/8)x+113/8 x=5

Y=-5/8+113/8=(113-5)/8=108/8

Y=13.5 hrs

Yes the estimated value of sleep by this function is reasonable as it is close to childhood more sleep is likely.

Part B

20yr old boy.

Y=-(1/8)x+113/8 x=20

Y=-20/8+113/8=(113-20)/8=93/8

Y=11.63 hrs

No the estimated value of sleep by this function is not reasonable as the normal sleep of 7-8 hrs is enough for adults.

Can someone tell me what’s going on here
lora16 [44]

Answer:

c = 105 degres

Step-by-step explanation:

When two lines cross like that and form an x, the opposite sides are equal (so the angle below the 75 degree one is also 75 degees). Using this, you can figure out the rest.

If both the top an bottom are equal, you know that 150 degres are taken (75+75) and you know that there can only be 360 degres in total here, so you subtract 150 from 360 and get 210. Now you know that the last two sides together are 210, and since they are equal, you divide it by two to get 105 degrees.

It takes a hose 2 minutes to fill a rectangular aquarium 8 inches long, 10 inches wide, and 14 inches tall. How long will it tak
kari74 [83]

Answer:

66 minutes, or 1 hour and 6 minutes.

Step-by-step explanation:

let us first do the rectangular aquarium:

8 x 10 = 80

80 x 14 = 1120

now the second box

23 x 25 = 575

575 x 33 = 18975

we can divide the boxes volume:

18975/575 = 33

so all we have to do is times 33 by 2 which equals:

66 minutes, or 1 hour and 6 minutes.
