Answer:
70 m/s
Step-by-step explanation:
<u>"The speed of a tidal wave in meters/second is given by the square root of the product of the acceleration due to gravity on Earth (9.8 meters/second2) and the depth of the ocean in meters":</u>
The sentence above can be interpreted into the equation shown below (letting speed of tidal wave be "s", acceleration due to gravity be "g", and depth be "d"):
<em><u>Given d = 500 and g = 9.8, we find speed (s):</u></em>
Hence, the speed is 70 meters per second.
Answer: Yes it does represent a dilation... It is enlarged..
Step-by-step explanation:
The student on the left end of the row can be any one of 30.
For each of those ...
The student in the next seat can be any one of the remaining 29.
For each of those ...
The student in the next seat can be any one of the remaining 28.
For each of those ...
The student on the right end of the row can be any one of the remaining 27.
The total number of ways to pick 4 students and seat them in the front row is
(30 x 29 x 28 x 27) = <em>657,720 ways.</em>
That's enough to do it a different way every school day for about 3,600 years !
(or until they all graduate, whichever comes first)
Answer:
10000 - 1000 + 1000 = 10000
Step-by-step explanation:
10 to the forth power = 10000 - 1000 = 9000 + 1000 = 10000
Answer:
2.5 bottles or 3 bottles
Step-by-step explanation:
Given that :
Dimension of lot :
22.5 yds by 20.4 yds
Area of lot = 22.5 * 20.4 = 459 yd²
Volume per bottle of herbicide = 12 fl oz
1.1 fl oz combined with water treats an area of 155 ft²
Number of 1.1 fl oz from 12 fl oz that can be obtained : 12 / 1.1 = 10.90
1 yard² = 9 feet²
459 yard² = (459 * 9) = 4131 feet²
Number of 151 feet² that can be obtained from 4131 feet²
4131 feet² / 155 ft²
= 27.3576 times
= 27.3576 / 10.909
= 2.507
This means he'll have to buy a minimum of 3 bottles if a fraction of a bottle can't be purchased.
