Answer:
11.3 units
Step-by-step explanation:
Let's find the length of one of the boxes.

Let's simplify c down to 1.41.
Now, there are 8 of these little boxes for the perimeter, let's multiply.

That can be simplified to the nearest tenth - 11.3
Hope this helped!
Multiply 3x by -6, it gives you -18 so I'm going to say D
Given two points A(x₁,y₁) and B(x₂,y₂) the distance betwen these points will be:
dist(A,B)=√[(x₂-x₁)²+(y₂-y₁)²].
We have these points: A(0,0) and B(6,3); its distance will be:
dist(A,B)=√[(6-0)²+(3-0)²]
=√(6²+3²)
=√(36+9)
=√45 ≈ 6.71
Answer: D. 6.71 units.
Answer:
Lara's average speed :
average speed = total distance / total time
=> 8 miles / 2.5 hours
=> 3.2 mph
Tim's average speed :
= total distance / total time
= 12 miles / 3.5 hours
= 3.43 mph
therefore,
Tim's average speed (3.43 mph) is greater.
