Answer:
8kg
Step-by-step explanation:
Force = Mass × Acceleration.
Where:
Force= 20N
Acceleration= 2.5m/s^2
Mass = ?
20 = m × 2.5
20= 2.5m
20/2.5 = m
8= m
m= 8Kg
The ratio is 2:5 yep
hope it helps how do you know?
Answer:
x=12
Step-by-step explanation:
This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that 
where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get, 
. Next, solve what is under the root to get, 
. Finally, square root 144 for the final answer b=12.
