Step-by-step explanation:
Let the number be x
so,
10 - x ≥ 5
Hope it helps ya
Your gonna wanna multiple (5/8)(5/8) which is 25/64 or about 39 percent. (I might not be entirely right, sorry. )

Answer:
1. 22583.5 J
2. 1248 kg
3. 78.09 m/s
Step-by-step explanation:
The formula for kinetic energy is ;
K.E = 1/2* m * v²
Where m is the mass and v is the velocity
1.
K.E = 1/2 * m*v²
K.E = 1/2 * 47 * 31²
K.E = 22583.5 J
2.
Velocity = 9.78 m/s.
Kinetic energy = 60,800 J
To get mass, apply the formula as;
K.E = 1/2 * m*v²
60,800 = 1/2 * m * 9.78²
60800 = 48.70845 m
60800/48.70845 = m
1248 = m
Mass = 1248 kg
3.
K.E = 143.3 J
Mass = 0.047 kg
Apply the formula;
K.E = 1/2 * m*v²
143.3 = 1/2 * 0.047 * v²
143.3 = 0.0235 v²
143.3/0.0235 = v²
6097.87 = v²
v = √6097.87
v= 78.09 m/s
Option B is correct.
Step-by-step explanation:
We need to identify which of the following equations has exactly one solution.
We will solve each equation to find the answer
A. 
Solving and finding value of x:

This equation has infinite number of solutions because both sides are equal to 0
B. 
Solving and finding value of x:

This equation has exactly one solution
C. 

This equation has no solution because both sides are not equal.
So, Option B is correct.
