<h3>Answer:  60</h3>

=================================================

Explanation:

Multiply the two values to get 4*15 = 60

Then divide by the GCF 1 to get 60/1 = 60. The GCF being 1 means the result hasn't changed.

------

Another example would be: "Find the LCM of 6 and 8". We would first do 6*8 = 48, then divide by the GCF 2 to get 48/2 = 24. The LCM of 6 and 8 is 24.

serious [3.7K]
This can be solved a couple of ways. One way is to use the Pythagorean theorem to write equations for the magnitude from the components of the forces. That is what was done in the graph here.

Another way is to use the Law of Cosines, which lets you make direct use of the angle between the vectors.
.. 13 = a^2 +b^2 -2ab*cos(90°)
.. 19 = a^2 +b^2 -2ab*cos(120°)
Subtracting the first equation from the second, we have
.. 6 = -2ab*cos(120°)
.. ab = 6

Substituting this into the first equation, we have
.. 13 = a^2 +(6/a)^2
.. a^4 -13a^2 +36 = 0
.. (a^2 -9)(a^2 -4) = 0
.. a = ±3 or ±2

The magnitudes of the two forces are 2N and 3N, in no particular order.

Find volume of sphere in cubic yards whose radius is 5 yard<br><br> Use pi = 3.14​
enyata [817]

Answer:

523.333 cubic yards

Step-by-step explanation:

The formula for the volume of a sphere is  \frac{4}{3}\pi r^{3} where r is the radius.

The radius of the given sphere is r=5 yards and \pi =3.14.

Therefore, we can substitute in the radius and solve:

V_{sphere}= \frac{4}{3}\*\times3.14\times  5^{3} =523.333 cubic yards

Solve the following equations with any method. Justify your reasoning. 1. (5x-8)=(8x-17) 2.(3x+5)+(4x-7)=180
3241004551 [841]
1. (5x-8)=(8x-17)
5x-8x=-17+8
-3x=-9
x=3

2. (3x+5) + (4x-7) =180
3x+5+4x-7=180
3x+4x=180-5+7
7x=182
x=26
