In terms of pi means to include pi in your answer. In other words, don't use 3.14 or 22/7 for pi.
Answer:
20 units
Step-by-step explanation:
The formula for the area:
A = bh × 1/2
B = 8 units
H = 5 units
8 × 5 = 40
40 × 1/2 = 20
Domain: All real numbers
Range: All real numbers
Since the function is linear it is a continuous straight line meaning that the domain and range are all real numbers.
2,400
20% of 3,000= 600
3,000 - 600= 2,400
The current weight 
is 15% less than the weight Angela had 1 year ago (
). Or we can write,
.
Thus Angela,s current weight is 85% of her weight one year ago.
