Answer:
5.25 miles per minute
Step-by-step explanation:
420/80 = 5.25 so it is 5.25 miles per minute as it is 80 minutes
8, as it is a 45-45-90 triangle, and if it has a side x not on the hypotenuse, the hypotenuse is x√2, and the other side is also x
<h3><u>Question:</u></h3>
Serena uses chalk to draw a straight line on the sidewalk. The line is 1/2 ft long. She wants to divide the line into sections that are each 1/8 ft long. How many sections will the line be divided into?
<h3><u>Answer:</u></h3>
The number of sections that the line is divided is 4
<h3><u>Solution:</u></h3>
Given that, Serena uses chalk to draw a straight line on the sidewalk
The line is 1/2 ft long. She wants to divide the line into sections that are each 1/8 ft long
From given,

To find: Number of sections can be made
The number of sections that can be made is found by dividing the total length of line by length of each section

Substituting the values, we get,

Thus number of sections that the line is divided is 4
Answer:
18.85 feet
Step-by-step explanation:
Determine the arc length of SR
Arc length = θ/360 × 2πr
r = 9 feet
θ =120°
Arc length = 120/360 × 2 × π × 9
= 18.849555922 feet
Approximately = 18.85 feet
Therefore, the arc length of SR = 18.85 feet
