Answer:
yes
Step-by-step explanation:
if it is a terminating decimal(a decimal that ends) it will be rational
The discounted clock would be 6 dollars. I found this by creating a table with 3/3, 2/3, and 1/3 on one side and the 18 across from 3/3 since it is the regular price. To find 2/3 I think we should find 1/3 first. To find that we simply divide 18 by 3 since we are finding one third of 18. Luckily 3 evenly goes into 18 6 times. Now we aren’t done, that is 1/3 so we double the 1/3 which is 2/3 and we double the 6 which is 12. Now that we know how much those cost, it says 2/3 off. The regular price was 18 and 2/3 was 12 so 18-2/3 is 18-12 which equals 6. The discounted alarm clock is $6.00.
Answer: 102
Step-by-step explanation:
Let the numbers be a, a+2 and a+4. Since the sum of three consecutive even numbers is 312, this will be:
a + a+2 + a+4 = 312
3a + 6 = 312
3a = 312 - 6
3a = 306
a= 306/3
a = 102
Therefore, the smallest number is 102.
Other numbers are 104 and 106.
