Answer:
An equation for each situation
A = 31 - 4t
B = 52 - 7t
The interval of time, t,, when Snowman A is taller than Snowman B is t > 7 hours i.e
The interval of time, t, when Snowman A is taller than Snowman B is from
7.01 hours and above.
Step-by-step explanation:
Let t represent the number of hours at which the snow melts
Let A represent the height of Snowman A t hours after sunrise
Let B represent the height of Snowman B tt hours after sunrise.
An equation for each situation
A = 31 - 4(t)
B = 52 - 7(t)
The interval of time, t, when Snowman A is taller than Snowman B.
A > B
31 - 4t > 52 - 7t
Collect like terms
-4t + 7t > 52 - 31
3t > 21
t > 21/3
t > 7
This means after 7 hours, Snowman A is taller Snowman B
The interval of time, t, when Snowman A is taller than Snowman B is from
7.01 hours and above.
