650,000 is the awnser because when you round if it's 5 or higher you add 1 is its less than 5 you leave it
Answer:
The equation for difference in altitude of the two helicopters is A = 650 - 100t
Step-by-step explanation:
Given;
The altitude of one helicopter is, A1 = 600 + 150t
The altitude of a second helicopter is, A2 = 1250 + 50t
Their difference in altitude, A at time t, is calculated as
A₂ - A₁ = A = (1250 + 50t) - (600 + 150t)
A₂ - A₁ = A = 1250 + 50t - 600 -150t
A₂ - A₁ = A = 1250 - 600 + 50t - 150t
A₂ - A₁ = A = 650 - 100t
Therefore, the equation for difference in altitude of the two helicopters is A = 650 - 100t
Answer: A
Step-by-step explanation:
Answer:
-12 °F
Step-by-step explanation:
To find the total change in temperature, multiply 6 by -2, since it dropped 2 degrees each hour for 6 hours.
6(-2)
= -12
This means -12°F was the total number of degrees the temperature dropped.
