James knows that when he walks, he takes about 120
Tpy6a [65]

Answer:

speed of James is: 3.75 miles/hour.

Step-by-step explanation:

We need to find the speed of James in miles per hour(mi/hr)

we know that 1 mile=5280 feet

James takes 120 steps in 1 minute so he will cover 120×60 steps in 1 hour.

i.e. he takes 7200 steps in 1 hour.

also each step of James=2.75 feet

total distance covered by James in 1 hour=2.75×7200 feet=19800 feet

19800feet=\frac{19800}{5280} miles=3.65miles

hence speed of James= (distance covered by james in 1 hour)/1 hour

speed of James=3.75 miles/hour.

Thanks!!

If the each side of equalaterial triangle is a cm. what is the area?​
Yuri [45]

Step-by-step explanation:

area \: of \: a \: triangle =  \frac{1}{2}  \times base \times height \\  \\ base =  \frac{a}{2} cm \\  {h}^{2}  +   {( \frac{a}{2} )}^{2}  =  {a}^{2}  \\  \\ h =  \sqrt{ {a}^{2} -  \frac{ {a}^{2} }{4}  }  \\  \\ area \: of \: triangle =  \frac{1}{2}  \times b \times h \\  =  \frac{1}{2}  \times  \frac{a}{2}  \times  \sqrt{ {a}^{2}  -  \frac{ {a}^{2} }{4} }  \\  \\  =  \frac{a}{4}  \times  \sqrt{ {a}^{2} -  \frac{ {a}^{2} }{4}  }
