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:
Total temperature change = -32.48 degrees
Step-by-step explanation:
Over 11.2 hours, the temperature changed -2.9 degrees each hour.
Total time elapsed = 11.2 hour.
Temperature change per hour = -2.9 degrees
Total temperature change = Total time elapsed x Temperature change per hour
Total temperature change = 11.2 x -2.9 = -32.48 degrees
So temperature is reduced by 32.48 degrees in 11.2 hours.
Total temperature change = -32.48 degrees
Answer:
two times a number plus two is eight
Step-by-step explanation:
Answer:
The first choice.
Step-by-step explanation:
The area is multiplied by (1/2)^2 = 1/4.
This is because lengths are one dimensional and areas are 2 dimensional.
I gotchu this time buddy so substitute 2x-1 for the second equation: 3(2x-1)=6x-5
Distribute 3x :6x-3=6x-5
Subtract 6x from both sides
-3=-5 which is not true so the answer is no solution
