Answer:
35.71m/s²
Step-by-step explanation:
using the formula force(F)=mass(m)×acceleration(a)
a =

F=15.0N
m=0.42kg
a=?
a=15÷0.42
a=35.71m/s²
Answer:
A. 45%=45/100=9/20
Step-by-step explanation:
45% is 45 out of 100 or <em>45/100</em>

Answer:
x=103°
Step-by-step explanation:
x+x-26=180
2x=180+26
2x=206
x=206/2=103°
To find percent decrease and increase you must subtract the original value (old value) with the new value. Then divide the value you get by the original value and multiply by 100:
165-158 = 7
7÷ 165 × 100 = 4.2424....% or 4.2% rounded to 2 significant figures.
