Answer:
R = 40t + 20
Step-by-step explanation:
We need to use the equation y = mx + b to solve this because it's linear.
"m" is the slope, or the rate. Here, we know that the population increases by 40 rabbits per month, which means m = 40.
"b" usually means that fixed, initial amount. Here, we know that the population begins at 20 rabbits, which means b = 20.
Plug these in:
R = mt + b
R = 40t + 20
Answer:
if it is 12:3 so you need to find 20:x
12/3 20/x= 20 is 5

Answer:
3/25 = 0.12 =12%
Step-by-step explanation:
Answer:
50 in²
Step-by-step explanation:
What is the area in square inches of the trapezoid below.
Area of a trapezoid = 1/2(b1 + b2) h
Where
b1 = First base = 8in
b2 = Second base = 12in
h = Height = 5in
Area of trapezoid = 1/2(8 + 12) × 5
= 1/2 × 20 × 5
= 50 in²
The area of the trapezoid is 50 square inches
√80.

We can rewrite as 4√5. To multiply the 4 back in to the square root, we square it and get √16*5 = √80.
