Answer:

the answer is 36654.52

Step-by-step explanation:

alright so if there are 86400 seconds in a day we substract 28800 bc thats how many seconds we have in 8 eight hours. That is 57600. divide it by 22, which is 2618.18. And multiply it by 14 bc thats how many times he blinks in 22 seconds. 36654.52

Step-by-step explanation:

24hours=86400seconds

8hours =28800seconds

Sam sleeps for 28800second

so 86400-28800=57600seconds.

Sam is awake for 57600seconds.

14blinks in 22seconds

xblinks in 57600seconds.

cross multiply

we have

22x = 806400

x=36654.5

Sam blinks for 36654.5 in a day

Answer:

Sphere Volume = (4/3) * PI * radius^3

radius = cube root (Sphere Volume) / (4/3)*PI

radius = cube root (5,600) / (4/3)*PI

radius = 11.016 cm

radius = 11 cm (rounded)

Answer is B

If x:y = 2:5, find the value of (-x+3y):(2x+y)

Anit [1.1K]

Answer:

let x=2t and y=5t

-x+3y = -2t+15t = 13t

2x+y = 4t+5t = 9t

So the ratio is 13t : 9t

So, the ratio is 13 : 9

PLEASE HELP ME!!!!!!!!!!!!!!!!!!

Answer:

a) 4 - $vt - d = \frac{1}{2} at^{2}$

b) 1 - $2(vt - d) = at^{2}$

c) 6 - $\frac{2(vt - d)}{t^{2}} = a$

Step-by-step explanation:

It simply asks the steps to go from the original displacement formula to isolate a (the acceleration). It's just a matter of moving items around.

We start with:

$d = vt - \frac{1}{2} at^{2}$

We then move the vt part on the left side, then multiply each side by -1 (to get rid of the negative on the at side and to match answer choice #4):

$vt - d = \frac{1}{2} at^{2}$

Then we multiply each side by 2 to get rid of the 1/2, answer #1:

$2(vt - d) = at^{2}$

Finally, we divide each side by t^2 to isolate a (answer #6):

$\frac{2(vt - d)}{t^{2}} = a$

Carol and Janis decide to sew fancy masks to sell on Etsy. Carol can cut, pin, sew and pack a mask in 30 minutes. Working togeth

Hoochie [10]

it would take Janis 14 minutes to complete a package alone

<h3>How to determine the value</h3>

From the information given,

Let's say that

Carol working time = x = 30 minutes

Janis working time = y

x + y = 16 minutes

Let's make 'y' the subject

30 - 16 = y

y= 14 minutes

Thus, it would take Janis 14 minutes to complete a package alone
