Answer:
should be 22.5 for the first one and 324 for the second
Step-by-step explanation:
pi = 180° so you can take the multiplier by pi and switch pi to be 180
Answer:
x = 21
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
Combine like terms. (x + 3x) and (-4 + 100)
x - 4 + 3x + 100 = 180
Subtract 96 on both sides.
4x + 96 = 180
-96 -96
Divide 4 on both sides.
4x = 84
--- -----
4 4
And you get a solution of 21.
x = 21
<u>Check:</u>
Substitute 21 into x.
Add/Subtract from left to right.
21 - 4 + 3(21) + 100 = 180
17 + 63 + 100 = 180
80 + 100 = 180
180 = 180
Answer:
Force= Mass×Accelaraion
F=m×a
But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²
Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)
So now we have,
2000N= m×4.47m/s²
= 2000/4.47m/s²=m
= 447.42
Thus the mass of the object is 447.42 (i am not sure of units)
20+3=23 divided by 2 ==11.5
