Answer:
Piyush walks faster than Laura
Step-by-step explanation:
we know that
The rate or speed is equal to the slope of the linear equation
<em>Laura</em>
y=3.5x
The slope is 
<em>Piyush</em>
Determine the slope of the line
we have the points
(0,0) and (4,18)
The line represent a direct variation (because passes through the origin)
so

For x=4 h, y=18 mi
substitute

Compare the slopes

therefore
Piyush walks faster than Laura
Answer:

Step-by-step explanation:
we know that
The inscribed angle is half that of the arc comprising
so
![m\angle y=\frac{1}{2}[96^o]](https://tex.z-dn.net/?f=m%5Cangle%20y%3D%5Cfrac%7B1%7D%7B2%7D%5B96%5Eo%5D)

Answer:
10π feet, or about 31.42 feet
Step-by-step explanation:
Diameter = 2 times radius, so the radius is 5 feet.
The question is asking us for the circumference - the distance around the circle. Plug our radius into the formula.
C = 2πr
C = 2π(5)
<u>C = 10π feet = about 31.42 feet</u>
Two angles adjacent angles that add up to 180 degrees
Answer:
68
Step-by-step explanation:
m7 + m8 = Straight line = 180
So, m7 = 180 - 112 = 68
