Answer:
7 and 7/11
Step-by-step explanation:
Lines that are perpendicular will intersect only once.
Lines that are parallel will NEVER intersect.
I'll start by expanding everything, and 10^(x) means we move the decimal x places to the right. If we move the decimal to the right but there's no number there, that number is 0.
The populations are as follows (in the order in the graph) -
127,180,000
200,000,000
80,619,000
63,708,000
173,615,000
152,510,000
The first difference is the number of digits. The more, the better. The two that stand out at the bottom are Germany and the UK. Next, we look at the leftmost number. Since 6<8, Germany's population > UK's population. All other countries are greater than Germany. Next, we look at the next smallest amount of digits, which is every other country. We look at the first number, which gives us Japan, Nigeria and Bangladesh. Next, we look at the second number, and since 2<5<7, Japan is smaller than Bangladesh and Nigeria is bigger than Bangladesh. Our current list is as follows:
United Kingdom (UK), Germany, Japan, Bangladesh, Nigeria. Since Brazil
has been proven to be greater than the rest (as it has more digits and 2>1), our list is now
United Kingdom (UK), Germany, Japan, Bangladesh, Nigeria, Brazil
Answer:
In total 5 packets of rubber bands are needed.
Out of which 5 rubber bands are left.
Step-by-step explanation:
The number of rubber bands needed by 1 student = 5
The total number of students = 8
So, the total rubber bands needed by all students
= Total students x Number of rubber bands needed by 1 student
= 8 x 5 = 40 bands
Now 1 packet of rubber bands = 9 bands
⇒ 2 packets = 2 x ( 9 bands) = 18 bands
⇒ 3 packets = 3 x ( 9 bands) = 27 bands
Similarly, 4 packets = 36 bands , 5 packets = 45 bands
Now, if we buy 4 packet of bands, there are 36 rubber bands which are LESS THAN THE TOTAL STUDENTS.
So, we buy 5 packets.
We have in total 45 bands, but the total students = 40
So, the number of left rubber bands = Total bands - Total students
= 45 - 40 = 5
Hence, in total 5 packets of rubber bands are needed, and out of which 5 rubber bands are left.
