Answer:
The integer that represents the change in the temperature each week = 5
The temperature of the weather drops 5°F each week
Step-by-step explanation:
The given parameters regarding the weather are;
The range over which the temperature dropped = 20°F
The duration over which the temperature dropped = 4 weeks
The rate at which the weather dropped each week = The same amount (constant rate)
Therefore, we have;
For a constant rate of change, the rate of change of the temperature of the weather, m, is given as follows;
m = (The change in the temperature)/(The duration of the change)
m = 20°F/(4 weeks) = 5°F/week
The integer that represents the change in the temperature each week = 5
Answer:
BC=6
Step-by-step explanation:
The perimeter is the sum of all the side lengths.
Thus, add up all the sides.
And we already know the perimeter is 64. Thus:
Combine like terms and add the numbers:
Subtract 22 from both sides:
Divide by 6:
So, z is 7.
BC is z-1. Therefore:
So, BC is 6.
