An antelope can run a speed of 61 miles per hour. What is this speed in yards per second? Round to the nearest hundredth
DochEvi [55]

Answer:

= 29.82 yards/second

Step-by-step explanation:

The speed is given in the problem.  We just need to convert its units.  The multiplicative identity (that is, 1) may be used to change the units without changing the value.  (note:  do you know what the additive identity is?)

     61 miles per hour

    (61 miles) / (1 hour)

   (61 miles)/(1 hour)*1

   ((61 miles)/(1 hour))*((5280 feet)/(1 mile))

   ((61 miles)/(1 hour))*((5280 feet)/(1 mile))*((1 yard)/(3 feet))*((1 hour)/(60 minutes))*((1 minute)/(60 seconds))

      note:  miles, feet, hours, minutes cancel out; leaving yards per second

    (61/1)*(5280/1)*(1/3)*(1/60)*(1/60)   yards/second          (note: I write that way to paste into Excel)

The radio of boys to girls in Miss ronilo's math class is 3 to 1 what percent of the classes is girls
9966 [12]

Imagine that the class only had 4 students (unrealistic most likely, but small numbers help much better I think)

If we had 4 students and 3 were boys, then 4-3 = 1 girl is in the class. This makes the ratio of boys to girls be 3 to 1. In other words, there are 3 times as many boys compared to girls.

Divide the number of girls (1) over the number of students total (4) to get 1/4 = 0.25 = 25%

<h3>Answer: 25%</h3>
