Mr. Rr the Rreliable Rrobot has been programmed to whistle every $18$ seconds and do a jumping jack every $42$ seconds, starting
sveta [45]

Answer:

7 times during the first 15 minutes

Step-by-step explanation:

Remember that

1\ min=60\ sec

so

15\ min=15(60)=900\ sec

Decompose the numbers 18 and 42 in prime factors

we know that

18=(2)(3^2)

42=(2)(3)(7)

Find the least common multiple (LCM)

The LCM is

(2)(3^2)(7)=126\ sec

we need to find all multiples of 126 that are less than or equal 900.

126*1=126\ sec\\126*2=252\ sec\\126*3=378\ sec\\126*4=504\ sec\\126*5=630\ sec\\126*6=756\ sec\\126*7=882\ sec

therefore

7 times during the first 15 minutes

A factory produces 3/4 of a mile of thread every 1/4 of an hour. What is the unit rate of miles of thread per hour?
marissa [1.9K]
Isn’t this 12/4 of a mile of thread every hour? If the factory produces 3/4 of a mile of thread every 1/4 of an hour, then all you need to do is 3/4 x 4. 1/4 is like .25 so to make a whole number, you have to do .25 x4 which makes the whole. I don’t know if my explanation is correct or not but I do believe my answer is. (12/4 is 3)
