Step-by-step explanation:
the answer is the first one
I believe the answer is
Nuclear radiation ionizes the atom...
sorry if wrong
F=60, s=60/2=30
(60-x)/(30-x)=4
60-x=120-4x
60+3x=120
3x=60
x=20
s=30-x
s=30-20
s=10
So the boy was 10 years old when his father was four times his age.
Answer:
Plural of Axis. Pronounced "ak-seez". Axes often means the "x" and "y" lines that cross at right angles to make a graph. See: Axis (graph) Cartesian Coordinates.
Step-by-step explanation:
You'd use tangent for this.
opposite / adjacent
tan 60* = x/14
multiply both sides by 14
tan 60* = 1.73
tan 60* (1.73 x 14) = x
24.22 = x
Your answer should be 24.22
