Answer:
A line passing through (1, 3) and (5, 11)
Rate of change = 2
Step-by-step explanation:
- <em>Rate of change = change in y / change in x</em>
- <em>r = Δy/Δx</em>
<u>Let's get the rate of change for each line:</u>
A line passing through (-1, 4) and (1, 7).
- r = (7 - 4) / (1 -(-1)) = 3/2
A line passing through (1, 3) and (5, 11).
- r = (11 - 3) / (5 - 1) = 8/4 = 2
A line passing through (1, 1) and (4, -3).
- r = (- 3 - 1) / (4 - 1) = -4/3
A line passing through (0, 6) and (12, 9)
- r = (9 - 6) / (12 - 0) = 3/12 = 1/4
<u>Comparing the values of r, we can see the greatest one is</u> 2 for the line passing through (1, 3) and (5, 11)
P = 3r + 2s --> P - 3r = 3r - 3r + 2s
2s = P - 3r --> 2s/2 = (P - 3r)/2
s = (P - 3r)/2
Answer:
24 units³
Step-by-step explanation:
Formula:
Volume (V) = length (l) × width (w) × height (h)
V=3×4×2=24 units³

Answer:
Part a) The area of the actual floor is 
Part b) The ratio of the area in the drawing to the actual area is 
Step-by-step explanation:
we know that
The scale drawing is 
step 1
Find the dimensions of the square on a scale drawing
The area of a square is equal to
where
b is the length side of the square
so
step 2
Find the dimensions of the actual floor
Divide the length of the floor on the drawing by the scale drawing
step 3
Find the area of the actual floor
The area of a square is equal to
substitute
step 4
Find the ratio of the area in the drawing to the actual area
Simplify
Divide by 64 both numerator and denominator
