At total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls

ioda

Answer:

$Day\ 3 = 1\frac{3}{12}$

Step-by-step explanation:

Given

$Total = 2ft$

$Day\ 1 = \frac{1}{6}$

$Day\ 2 = \frac{7}{12}$

Required

Determine the amount of snow on day 3

This can be calculated using:

$Day\ 1 + Day\ 2 + Day\ 3 = Total$

Substitute values for the known parameters

$\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2$

Collect Like Terms

$Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}$

Take LCM

$Day\ 3 = \frac{24 - 2 - 7}{12}$

$Day\ 3 = \frac{15}{12}$

Express as mixed number

$Day\ 3 = 1\frac{3}{12}$

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.

<u><em>How to solve:</em></u>

First use the formula: C = 3.14d
Replace the d value with 30 and solve the equation:

C = 3.14 x 30 ⇒ 94.2477796077

Then solve the equation again but 21 as the d value:

C = 3.14 x 21 ⇒ 65.9734457254

Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8
