From the graph, angelica's house is represented by the point (4, 3) and the gas station is represented by the point (10, 8).
The distance between two given points in the xy-plane is given by
where:

A ratio is a comparison of two numbers that can be written in multiple ways such as:
Word: There are ___x for every ___ y
Fraction: y/x
Ordered pair: (x,y)
Ratio:x:y
Proportional is a type of relationship where, oh a graph, a line goes through the 0,0 point and when you divide y/x at any point, you will get the same answer.

Answer:
4266
Step-by-step explanation:
Okay! let's start with finding what 3% of 5400 birds is
3% is .03 as a decimal. We can find 3% of 5400 by multiplying 5400 by .03
5400×.03= 162
If our rainforest is losing 3% a year, that means we are losing 162 birds a year.
Let's turn it into an equation! x will be the number of years
5400-162x= number of birds left after x years
Now put 7 in for x
5400-(162×7)= 4266 birds

Answer:
If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.
