stepladder [879]

Answer:

12\frac{1}{8}\ yd

Step-by-step explanation:

we know that

The total fabric that Mrs. Lin needs is equal to

3(1\frac{2}{3})+2\frac{5}{8}+2(2\frac{1}{4})

Convert mixed number to an improper fraction

1\frac{2}{3}=1+\frac{2}{3}=\frac{5}{3}

2\frac{5}{8}=2+\frac{5}{8}=\frac{21}{8}

2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}

substitute

3(\frac{5}{3})+\frac{21}{8}+2(\frac{9}{4})

5+\frac{21}{8}+\frac{9}{2}

\frac{40+21+36}{8}=\frac{97}{8}\ yd

Convert to mixed number

\frac{97}{8}\ yd= \frac{96}{8}+\frac{1}{8}=12\frac{1}{8}\ yd

sergeinik [125]

Answer:

v = 650\,\frac{ft}{min}

Step-by-step explanation:

Linear speed of the wheel is given by the following formula:

v = R\cdot \omega

v = (5\,\frac{rad}{s} )\cdot (26\,in)\cdot (\frac{1\,ft}{12\,in} )\cdot (\frac{60\,sec}{1\,min} )

v = 650\,\frac{ft}{min}
