Answer:
Option A - 
Step-by-step explanation:
Given : Aricela is trying to estimate the distance between her house and the park. On a map with a scale of 0.5 in. = 2 miles, the distance between her house and the park is 2.75 in.
To find : Which proportion can Aricela use to determine the distance, d, between her house and the park?
Solution :
The distance between her house and the park is 'd' miles.
A scale of 0.5 in. = 2 miles
The distance between her house and the park is 2.75 in.
i.e. the scale is 2.75 in. = d miles
The proportion form is

Therefore, proportion can Aricela use to determine is
.
So, option A is correct.
Answer:

Step-by-step explanation:
we know that
The sum of the internal angles of a kite is equal to 
so
In this problem we have




Answer: 31.25
Explanation: 6.25 x5 = 31.25 kilometers
They build 31.25 kilometers of road
In this problem, you have to find the y- intercept of

. I graphed mine into a graphing calculator. An algebraic way to find it is to input x=0 in the function. The y-intercept is 5. You can see the y-intercept for the new one is -2. That means we shifted the graph down 7 units. (Vertical Shift down 7)
