Answer: The total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.
Step-by-step explanation:
Volume of sphere :-
, where r is the radius of the sphere.
Given : Diameter of the bubble = 0.01 m
Then Radius of the bubble = 
Volume of each bubble:-
Also, Number of bubbles in each sheet = 1,000,000
Then , the total volume of air contained in the bubbles of one sheet of bubble wrap will be :-
Hence, the total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.
Answer:
Step-by-step explanation:
<u>The speed of sound in water:</u>
<u>Time:</u>
- t = 10 min = 10*60 sec = 600 sec
or
- t = 1 hour = 60 min = 60*60 sec = 3600 sec
<u>Distance in 10 min:</u>
- d = s*t
- d = 1500 *600 = 900 000 m = 900 km
<u>Distance in 1 hour:</u>
- d = 1500*3600 = 5 400 000 m = 5400 km
1.
The equation for this problem would be
y = (?)x + 190
With y being the height after a given amount of years and x being the amount of years passing. We would need to find ?, the rate of how fast the tree grows. The problem gives us y = 274 centimeters and x = 3 years
Let’s plug in and solve for ?
274 = ?(3) + 190
84 = ?3
28 = ?
The tree grew 28 cm per year
2.
Since we know the rate of change and y, let’s just plug in values
344 = 28x + 190
154 = 28x
5.5 = x
5.5 years since Renata moved.
