Answer:
- Grayson had 10 inches of snow in his lawn
- the snow falls at a constant rate of 0.5 inches per hour
- no snow was melting
- the snow has fallen for 3 hours
Let y be the height of the snow in the lawn
Grayson had 10 inches at the beginning (at t=0) so y= 10
3 hours passed so y= 10 + 3*0.5 = 11.5 inches
Grayson had 11.5 inches after three hours
Assuming that the snow continued to fall for an unkhown time t
y = 0.5*t + 10
we had 10 at the beginning so we add 10 (+10)
the snow is growing by 0.5 inches in the single hour so we multiply by 0.5
t is the time and it can 4, 5, 6 ...... hours
Just like a function :
- 0.5 is the slope
- t is the variable
- 10 is the y-intercept
Answer:
8.4
Step-by-step explanation:
50 ÷ 25 = 2
(2)2 x 7 x 0.3
4 x 2.1
