Answer:
<em>The PIN is 1147</em>
Step-by-step explanation:
<u>Prime numbers</u>
These are integer numbers that only divide exactly by themselves and by 1. To find the first possible prime number between 1,000 and 1,500, calculate the square root of 1,000.
Thus, the first prime to consider is 31. Write the consecutive primes from 31:
31 , 37 , 41 , 43
We can see the only two consecutive primes whose product lies in the given interval are 31 and 37. Thus, the PIN is 31*37=1147
Answer:
what is the question lol
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
In other words, does the sum of 5/18, 1/9 and 1/6 exceed, equal or come out to less than 1/2?
The LCD of 5/18, 1/9 and 1/6 is 18. Thus, these three fractions are equal to
5/18, 2/9 and 3/18, and their sum is 10/18, or 5/9. Thus, the part of the page covered with text is 1 less 5/9, or 4/9. No, the text does not cover more than half of the page.
Answer:
These results, 7 and 9, have a product of 63, as stated.
Step-by-step explanation:
Represent the first odd number by x and the first consecutive odd number by x + 2. Then the product of these two numbers is x(x + 2) and it equals 63.
Solve for x. Perform the indicated multiplication, obtaining
x^2 + 2x - 63 = 0
Solve this by factoring: (x + 9)(x - 7) = 0
Then x could be either -9 or +7. If we let x = 7 then the first consecutive odd number is 7 + 2, or 9. These results, 7 and 9, have a product of 63, as stated.
