Your bike has a wheel diameter of 29 inches. You are traveling and your wheels are rotating at 148 revolutions per minute. What
larisa [96]

Answer:

12.77 miles per hour

Step-by-step explanation:

Step 1

Convert the diameter from inches to feet

Your bike has a wheel diameter of 29 inches.

1 inch = 0.0833 feet

29 inches =

29 × 0.0833 feet

= 2.41667 feet

Step 2

Circumference of the tire = πD

= π × 2.41667 feet

= 7.5921927182 feet

Step 3

The number feet traveled per hour is

148 revolutions per minute × 7.5921927182 feet

= 1123.6445223 feet per minute

60 minutes = 1 hour

Hence,

1123.6445223 × 60 =

67418.671337 feet per hour.

Converting from Feet per hour to Miles per hours

1 mile = 5280 feet

= 67418.671337 feet per hour/5280 feet

= 12.768687753 miles per hour

Approximately = 12.769 miles per hour

Solve the expression x^2-100=0
enot [183]

Answer:

x = ± 10

Step-by-step explanation:

Given

x² - 100 = 0 ( add 100 to both sides )

x² = 100 ( take the square root of both sides )

x = ± \sqrt{100} ← note plus or minus, hence

x = ± 10

Then plug everything in

(8±√(-8²-4*4*3))/(2*4)

(8±√16)/8

To calculate the ± we need to do when where it's adding and then negative

we have

(8+4)/8=3/2

and hten

(8-4)/8=1/2
