Answer:
4 minutes
Step-by-step explanation:
make equation
0.25+(0.15x)= 0.85
solve for x
0.15x= 0.60
x=4
6+4/5a=9/10a
make bottom numbers same
into 10
60/10+8/10a=9/10a
minus 8/10a from both sides
60/10=1/10a
multiply both sides by 10
60=a
45, 45, 90
45 *π/180 = π/4
90 *π/180 =π/2
45, 45, 90 is the same as π/4, π/4, π/2
