Answer: If in 1980 we had N people who were at least 100 years old, then in 2010 we had N*1.66 people who were at least 100 years old.
Step-by-step explanation:
A really simple conditional statement can be written as:
If P, then Q
Where P is the hypothesis, and Q is the conclusion.
In this case, we know that:
"The number of people with age equal or larger than 100 years old, grew about 66% from 1980 to 2010"
This means that if in 1980 we had N people in that age range, in 2010 we have N*(166%/100%) = N*1.66
Then we can write a conditional statement:
If in 1980 we had N people who were at least 100 years old, then in 2010 we had N*1.66 people who were at least 100 years old.

Answer:
all of them (A, B, C, D)
Step-by-step explanation:
Two unique points define a line. <em>Any</em> pair of unique points will always be collinear (reside on the same line).
Each of the points listed, together with (2, 1), will define a line. The two points will be collinear.
Answer:
The pencil marks on your page show you exactly how to do that.
Step-by-step explanation:
Take advantage of two rules of exponents:
![\sqrt[n]{x}=x^{\frac{1}{n}}\\\\x^{-n}=\dfrac{1}{x^{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D%3Dx%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%5C%5C%5C%5Cx%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Bx%5E%7Bn%7D%7D)
![(d)\quad x^{\frac{-1}{5}}=\dfrac{1}{x^{\frac{1}{5}}}=\dfrac{1}{\sqrt[5]{x}}\\\\(h)\quad x^{\frac{-2}{11}}=\dfrac{1}{x^{\frac{2}{11}}}=\dfrac{1}{\sqrt[11]{x^{2}}}](https://tex.z-dn.net/?f=%28d%29%5Cquad%20x%5E%7B%5Cfrac%7B-1%7D%7B5%7D%7D%3D%5Cdfrac%7B1%7D%7Bx%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D%7D%3D%5Cdfrac%7B1%7D%7B%5Csqrt%5B5%5D%7Bx%7D%7D%5C%5C%5C%5C%28h%29%5Cquad%20x%5E%7B%5Cfrac%7B-2%7D%7B11%7D%7D%3D%5Cdfrac%7B1%7D%7Bx%5E%7B%5Cfrac%7B2%7D%7B11%7D%7D%7D%3D%5Cdfrac%7B1%7D%7B%5Csqrt%5B11%5D%7Bx%5E%7B2%7D%7D%7D)
We see that each triangle takes up precisely one half of the parallelogram. From this, we see that the area of a triangle is one half the area of a parallelogram, or the area of a parallelogram is two times the area of a triangle
Answer:
i think it's 15 because if you use 5 and you have to do it by 3 it should be 15
