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

$1\ min=60\ sec$

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

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 certain quantity decays exponentially over time. The initial quantity at t = 0 is 25,000. The quantity decays at a rate of 5%.

7nadin3 [17]

In order to sole the problem you need to create an equation to model what you are trying to do.
You end up with an equation looking like
25000*0.95^t
25000 is the starting value when t=0
95% is the amount remaining after the 5% decay
0.95 is being raised to the power of t to determine how many times it has decayed
When t=3 the equation should be
25000*0.95^3=21434.375
