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

You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?
stiv31 [10]
Buying it 10% discount without tax is the best option. With card you still have the tax plus the card fee you pay annually to add to it. On the online purchase, you still have the tax plus the 5 shipping charge.
