Answer:
<u></u>
Explanation:
The measure of how fast the wrestler gained weight, in kg per month, is the weight gain rate.
The table is:
Time (months) Weight (kg)
0.5 80.6
2 88.4
3.5 96.2
The weight gain rate, WGR, for a period may be calculated as:
- WGR = [ weight gain ] / [period]
- WGR = [final weight - initial weight] / [final time - initial time]
- WGR₁ = [88.4 kg - 80.6 kg] / [2 month - 0.5 month] = 7.8 kg / 1.5 month = 5.2 kg / month
- WGR₂ = [96.2 kg - 88.4 kg] / [3.5 month - 2 month] = 7.8 kg / 1.5 month = 5.2 kg / month.
As you see, the wrestler gained weight at a constant rate of 5.2 kg per month.
Answer:
C) The song shop
Step-by-step explanation:
Divide all prices by the amount of songs purchased. example: 7.92/6=1.32
Distribute on both sides
2x - 8 = 6x + 12
Move x to one side
-20 = 4x
Divide by 4
-5 = x
