The ratio of its width to its length is; 5 :9.
The ratio of its length to its perimeter is; 9: 28.
<h3>What is the ratio of its width to its length?</h3>
1). From the task content, the land measures 4.5 km long and 2.5 km wide. Hence, the ratios is; 2.5: 4.5.
Therefore, we have; 5: 9 by expression as whole number ratios.
2) Since the perimeter of the rectangle is; 2(2.5+4.5) = 14.
The ratio of length to perimeter expressed simply is therefore; 9: 28.

Answer:
Positive correlation.
Step-by-step explanation:
This is a positive correlation. Because the dots don't jump around too much, they are steadily moving in one direction, so they have correlation.
But also, the dots are moving upwards, in a positive direction. So, that's why they have a positive correlation.
Answer:
Both candles will have the same height after 4 hours.
Step-by-step explanation:
The equation for the amount of candle remaining can be given by the following equations:
In which Q(t) is the amount after t hours, Q(0) is the initial amount and a is how much it decreases, in inches, per hour.
Red candle:
8 inches tall and burns at a rate of 7 divided by 10 inch per hour. This means that 
. So
Blue candle:
6 inches tall and burns at a rate of 1 divided by 5 inch per hour. This means that 
. So
After how many hours will both candles be the same height ?
This is t when
![0.2t - 0.7t = 6 - 8[/yrc][tex]-0.5t = -2](https://tex.z-dn.net/?f=0.2t%20-%200.7t%20%3D%206%20-%208%5B%2Fyrc%5D%3C%2Fp%3E%3Cp%3E%5Btex%5D-0.5t%20%3D%20-2)
Multiplying by (-1)
Both candles will have the same height after 4 hours.
