Answer:
Mikhail is 42 years old
Step-by-step explanation:
Let's say that the unknown value here is c. Although we are given two points on the line, it is only necessary to use one as there is only one unknown value, so let's say we choose the point (6, -12) and substitute this into the equation:
-12 = 1(6) - c
-12 - 6 = -c
-18 = -c
c = 18
Thus the equation for the line is y = 1x - 18
Area of the box:
A = 2 a² + 4 a h = 600 cm²
h = a ( the box is a cube )
A = 6 a² = 600 cm²
a² = 100
a = 10 cm
V = a³ = 10³ = 1000 cm³
Answer:
Hours spent for snowboarding = 1 hour 35 minutes
Step-by-step explanation:
Total hours spent for skiing and snowboarding = 3 hours
Hours spent for skiing = 1 hours 25 minutes
How long did he spend snowboarding?
Hours spent for snowboarding = Total hours spent for skiing and snowboarding - Hours spent for skiing = 1 hours 25 minutes
= 3 hours - 1 hours 25 minutes
1 hour = 60 minutes
3 hours = 180 minutes
1 hours 25 minutes = 85 minutes
3 hours - 1 hours 25 minutes
= 180 minutes - 85 minutes
= 95 minutes
95 minutes = 1 hour 35 minutes
Hours spent for snowboarding = 1 hour 35 minutes
