Step-by-step explanation:
Newton's Universal Law Of Gravitation
Newton discovered that all objects attract each other with a force of gravitational attraction which is proportional to their masses and inversely proportional to the square of the distance between them.
Where are the masses in kg and d is the distance between them in meters.
In the problem, we have

Step-by-step explanation: Given in the question that Lana completed a 10-mile race in 90 minutes by running and walking both. She usually runs at a pace of 8.5 minutes per mile and walks at a pace of 12 minutes per mile. We need to find the number of minutes for which she ran and walk throughout the race.
Let, Lana runs for 'x' miles and walks for 'y' miles. Then, we have
Multiplying the first equation by 8.5 and subtracting from the second equation, we have
Therefore,
Thus, time for which Lana ran is
And, the time for which Lana walks is
Thus, the answers are
Answer:
yes a scalene right angle triangle can be found for 25 for area.
Also isosceles right triangle but none for equilateral triangle.
Step-by-step explanation:
3 x 2 x 4 =25.2
3.5 x 2.5 x 5= 25
2.103 x 2.9 x 4.1 = 25
2.343 x 3.234 x 3.30 = 25
Also an isosceles right side triangle
2.7 x 2.7 x 3.43 = 25
No equilateral right side triangles can be found.
The decimals can not be larger than the hypotenuse for equilateral sides that equal 25 and 25/3 and you cannot use reoccurring decimals for angles and their sides.
25 is not a great number for squares as only 5 or 1 divide equally.
There are better numbers like 20, 40, 60, 18. 24, 36 etc. or 16.8
but for squares 9. 16. 25, 36 <u>I would say 36 and 64 are better square numbers </u>as they do not have any prime numbers that divide into it ie) like 9, 27 example where 3 x 3 x 3 is the only triangle that could be found without using decimal for an area of 27.
