Step-by-step explanation:
How do you find the LCM of 7 and 12?
What is the LCM of 12 and 7?
Find the prime factorization of 12.
Find the prime factorization of 7. 7 = 7.
LCM = 2 × 2 × 3 × 7.
LCM = 84.
Enlargement because all sides are being multiplied by 3 times their original amount making if it were a scale factor that were a fraction then it would be a reduction
The answer in this question is A, D and E, we might conclude if a random sample of 36 time interval between eruption has a mean longer that 104 minutes, I can conclude that the population means may be greater than 91 and the probability mean must be more that 91, since the probability is low and also the population mean is 91, and this is an example of a typical sampling result.
#43 is 3 Slices because 12 divided by 4=3
#44 lets work out a bit more. She Practiced 4 hours and 30 minutes each week. There are typically 4 weeks in a month, so we multiply 4 times 4 which is 16. But this isn't our answer because we have the extra half hour. We multiply the half hours times 4, and we have and extra 2 hours on our hands. So this means she Practiced 18 hours each month.
#46 First, You convert everything to inches.
2' 8'=24+8=32 inches.
Divide that 32 in half, and you get 16. 16 inches=16 times 12 =192.
192 over 32 =6.
So in total, 6 boards is your answer :)
