Answer:
I believe the answer is 5
Step-by-step explanation
12 - 7 = 5
Answer:
<u>8. and anything less</u>
Step-by-step explanation:
The line thing would be pointing to the left as 8 and lower fit the solutions.
8 - 4 = 4 which is less than 5
7 - 4 = 3 which is less than 5
6 - 4 = 2 which is less than 5
If you were to carry on testing these where <em>X</em> is getting smaller in value, it will never end. Any number above 8 will not work
Step-by-step explanation:
so, we need to find the smallest common multiple of 36 and 42.
that is the smallest number I can divide both by 36 and 42 without remain.
let's use the method of basic prime factors (we start with the smallest fitting prime number - 2 is a prime number too - and divide as often as possible, then continue with the next bigger prime number, until there is nothing left to divide) :
36 / 2 = 18
18 / 2 = 9
9 / 3 = 3
3 / 3 = 1 finished
therefore,
36 = 2×2×3×3
42 / 2 = 21
21 / 3 = 7
7 / 5 does not work
7 / 7 = 1 finished
therefore,
42 = 2×3×7
to find the smallest common multiple (SCM) we check the maximum length of each prime factor sequence.
and we see 2 times 2, 2 times 3 and 1 time 7.
so, the SCM = 2×2×3×3×7 = 252.
there is no smaller number that can be divided by both 36 and 42 without remain.
so, the rod must be at least 252 cm long to cut it into equally long pieces of either 36 cm (7 pieces) or 42 cm (6 pieces).
