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

24° 59' 60" is equivalent to how many degrees.

Lina20 [59]

This question requires you to covert minutes and seconds to degrees
In the question we have 59 minutes and 60 seconds that needs to be converted.
1°=60 minutes
59 minutes = 59÷60
=0.983333°
60 seconds = 1 minute
1 minute = 0.0166667°

So, <span>24° 59' 60" will be equal to
</span>

24°+0.983333°+0.0166667°= 24.9999997°

Norma-Jean [14]

Answer:

the incidence rate is 28.47

Step-by-step explanation:

The computation of the monthly incident rate of active cases is shown below:

Incidence rate is

= 1325 ÷ (47175 - 642) × 1000

= (1325 ÷ 46533 ) × 1000

= 28.47

hence, the incidence rate is 28.47
