The numbers between 30 and 40 whose only factors are one and themselves, also called prime numbers, are 31 and 37.<span> Prime numbers are useful in generating numerical passwords or codes that are difficult to crack. so A) is the answer

The distance from San Francisco to New York is 4140 km. Since the question asks how long it took the Humphrey family in km/hr (kilometers per hour), you would just divide 4140km by 6.
Why? Because it took them 6 hours to make a trip of 4140 km. Dividing 4140 by 6 gives you the distance they traveled per hour.
690 km/hr
Because the area in the drawing is 36 cm^2, one side length is 6 cm.
On the actual floor, this equates to 24 ft.
This means the area of the floor in real life is 576 square feet.
Therefore the ratio is 36 square centimetres : 576 square feet.
This is the same as 1 square centimetre : 16 square feet.
