Question-
To build a door frame, Anthony needs 2 pieces of lumber that each measure 98 1/4 inches and one piece of lumber that measure 39 1/2 inches. What is the total length of lumber that Anthony needs to build the frame?
Answer:
137 3/4 inches
Step-by-step explanation:
98 1/4 + 39 1/2
First, find the LCD (4)
98 1/4 + 39 2/4
98 + 39 = 137
1/4 + 2/4 = 3/4

Answer:
The angular speed is 3,227 rad/min
Step-by-step explanation:
Remember that
1 mile=63,360 inches
step 1
Find the circumference of the wheels
The circumference is equal to

we have

substitute


step 2
we know that
The speed of the wheel is 55 mi/h
<em><u>Convert to mi/min</u></em>
55 mi/h=55/60 mi/min
<u><em>Convert to in/min</em></u>
(55/60) mi/min=55*63,360/60 in/min= 58,080 in/min
we know that
The circumference of the wheel subtends a central angle of 2π radians
so
using proportion
Find out how much radians are 58,080 inches

therefore
The angular speed is 3,227 rad/min
