Answer:
Option (4) is correct.
The length of one side of the sandbox is inches.
Step-by-step explanation:
Given : Joan is building a sandbox in the shape of a regular pentagon. The perimeter of the pentagon is inches.
We have to find the length of one side of the sandbox.
Since, given sandbox is in shape of a regular pentagon.
So, Perimeter of pentagon is 5 times sides.
Perimeter of pentagon = 5 × sides
Given Perimeter is inches.
Thus, = 5 × sides
Divide both side by 5, we get,
= sides
Thus, The length of one side of the sandbox is inches.
Answer:
1) 5
2) 0.2
Step-by-step explanation:
The complete question is attached below.
The x-axis represents the time in hours and y-axis represents the distance in kilometers.
The first question asks how many kilometers, does Kendrick walk per hour. The straight line represents the distance traveled at various amounts of time.
The point marked on the graph is against time = 1 hour and Distance = 5 km. So this shows:
Kendrick walks 5 kilometers in 1 hour.
In next part, we have to find how much time Kendrick takes to walk 1 kilometer.
Since, we know that:
Kendrick walks 5 kilometers in time = 1 hour
Dividing both sides by 5, we can write:
Kendrick walks 1 kilometer in time = 1/5 hour = 0.2 hour
So, Kendrick takes 0.2 hours to walk 1 kilometer.
