Speed = Distance / time

Distance = Speed x time

In t hours, first plane travels = 600 t miles

In t hours, the second plane travels =150 t miles

After t hours the distance between the two planes is:

(600t+150t)= 750t ( since both travel in opposite directions)

When the distance is 900 miles:

750t= 900

Solve for t:

t= 900/750

t= 1.2 hours

After 1.2 hours.

1.2 x 60 = 72 minutes = 60 +12 = 1 hour and 12 minutes

Since both leave at 10 pm:

10am + 1 hour and 12 minutes : 11:12 am

They will be 900 miles apart at 11:12 am

Each one traveled:

Plane 1:

Distance: Speed x time = 600 mph x 1.2 = 720 miles

Plane 2:

Distance = Speed x time = 150 mph x 1.2 = 180 miles

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large
anzhelika [568]

Answer:

10 cm.

Step-by-step explanation:

We'll begin by calculating the area of the small bubble. This can be obtained as follow:

Radius (r) = 5 cm

Area (A) =?

Since the bubble is circular in nature, we shall use the formula for area of circle to determine the area of the bubble. This is illustrated below:

A = πr²

A = π × 5²

A = 25π cm²

Next, we shall determine the total area of the small bubbles. This can be obtained as follow:

Area of 1 bubble = 25π cm²

Therefore,

Area of 4 bubbles = 4 × 25π cm²

Area of 4 bubbles = 100π cm²

Finally, we shall determine the radius of the large bubble. This can be obtained as follow:

Area of large bubble = total area of small bubbles = 100π cm²

Radius (r) =?

A = πr²

100π = πr²

100 = r²

Take the square root of both side

r = √100

r = 10 cm

Thus, the radius of the large bubble is 10 cm

Solve the logarithmic equation . Round the answer to four decimal places . 2^x =25
levacccp [35]

Answer:

x = 4.6439

Step-by-step explanation:

2^x =25

Take the log of each side

log  2^x = log 25

We know that log a^b = b log a

x log 2 = log 25

Divide each side by log 2

x = log 25  / log 2

x =4.643856

Rounding to 4 decimal places

x = 4.6439

X + 5y = -27<br> -2x - 5y = 24
Rashid [163]

Answer:

Step-by-step explanation:

x+5y=-27

-2x-5y=24

If the signs are the same u minus if they are different u add

So they are different were gonna add

x+5y=-27

-2x-5y=24

-1=-3

You cant divide it further x=-3

Next were gonna subsitute in any equation

x(-3)+5y=-27

-3+5y=-27

+3 to -27

-7+3=-24

5y=24

24/5=4.8 y=4.8

I hope this helps.
