Answer:
6 × 5
Step-by-step explanation:
If you want to reduce the fraction 12/30, you want to find the greatest common factor of 12 and 30. We can find that by looking at the prime factorization of each number.
12 = 2·2·3
30 = 2·3·5
The greatest common factor is 2·3 = 6. This means ...
The product of interest is 6 × 5.
_____
<em>Additional comment</em>
Any of the factor pairs of 30 could be used. Only the one shown is useful for reducing the fraction to lowest terms.
30 = 1×30 = 2×15 = 3×10 = 5×6
Answer:
5 to 15 and 10 to 30
Step-by-step explanation:
Only 5 to 15 and 10 to 30 are equivalent:
<span>Using SOHCAHTOA we have:
</span><span>sin15 = <span>height / 3000
</span></span>height = 3000 sin 15 height = 776.46m
So, the height of the plane above the ground at this instant is <span>776.46m</span>
Answer:
a represent 1
and number is 11448.
Step-by-step explanation:
We know that a number is divisible by 9 if the sum of its digit is divisible by 9.
Given number aa448
sum of 4+4+8 = 16
number divisible by 9, 18 , 27,36
as we see sum of 448 is 16 , hence sum of a+a+4+4+8 should be number divisible by 9 and greater than 16 which is 18, 27,36
Let see of if sum of digits of aa448 is divisible by 18
a+a+4+4+8 = 18
2a + 16 = 18
2a = 18-16 = 2
a =2/2 = 1
Thus, number will be 11448
________________________________________
Let see of if sum of digits of aa448 is divisible by 27
a+a+4+4+8 = 27
2a = 27 - 16
2a = 11 = 2
a =11/2 = 5.5
as digit cannot be fraction of decimal, it can take value from 1 to 9 hence
sum of digits of aa448 is not divisible by 27
______________________________________________
Let see of if sum of digits of aa448 is divisible by 36
a+a+4+4+8 = 36
2a + 16 = 36
2a = 36-16 = 20
a =20/2 = 10
as digit can take value from 1 to 9 hence sum of digits of aa448 cannot be divisible by 36 or any higher number than 36 which is divisible by 9.
Thus , a represent 1
and number is 11448.
