Answer:
1.3 days
Step-by-step explanation:
1/5+1/4+1/3
12/60+20/60+15/60= 47/60
60/47
=1.3
The percent decrease is found by using the formula (original price - new price)/(original price). The percent decrease is then (2.49 - 1.99)/2.49 = 0.20 = 20%. A percent increase is found by using the formula (new price - original price)/(original price). The percent increase is then (2.49 - 1.99)/1.99 = 0.25 = 25%. The percents of change are not the same. The percent increase is greater.
HCF of 12 and 15 by Prime Factorization
1. As visible, 12 and 15 have only one common prime factor i.e. 3. Hence, the HCF of 12 and 15 is 3.
2. To find the HCF of 20 and 25, we will find the prime factorization of the given numbers, i.e. 20 = 2 × 2 × 5; 25 = 5 × 5. ⇒ Since 5 is the only common prime factor of 20 and 25. Hence, HCF (20, 25) = 5.
Hello,
Let's be x and y the 2 numbers
x+y=20==>y=20-x
P(x)=x*y=x*(20-x)=20x-x²
Max(P(x))==>P'(x)=0= 20-2x==>2x=20==>x=10
A product is maximum is the 2 numbers are equals;
Numbers are 10 and 10 and product=100
