Answer:
4/10 = 2/5
Step-by-step explanation:
It's asking you what's an equivalent fraction to 4/10. 4/10 is equivalent to 2/5 because the size of 2 parts out of 5 is the same size as 4 parts out of 10.
0.25 is the same as 1/4 so we have to find what is 1/4 of 24.5. To find this we need to divide 24.5 by 4. 24.5 ÷ 4 = 6.125
The final answer is: The builder will use 6.125 acres for the park.
Answer:
1) See figure attached
2)
a) 
And if we replace we got:

b) 
And if we replace we got:

Step-by-step explanation:
Part 1
We can see the plot in the figure attached.
Part 2
a)
For this case we have two points 
And we want to find the distance travelled between these two points and we can use the following formula from the euclidian distance between two points:

And if we replace we got:

b)
Since it takes two seconds in order to go from (6.9) to (10,15) we can use the definition of velocity:

And if we replace we got:

You can converte them to a common denominator like 6. 1/2 would be 3/6. 2/3 would be 4/6.
