$\bf ~~~~~~~~~~~~\textit{middle point of 2 points }
\\\\
(\stackrel{x_1}{-4}~,~\stackrel{y_1}{2})\qquad 
(\stackrel{x_2}{2}~,~\stackrel{y_2}{-2})
\qquad
% coordinates of midpoint 
\left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right)
\\\\\\
\left( \cfrac{2-4}{2}~~,~~\cfrac{-2+2}{2} \right)\implies \left( \cfrac{-2}{2}~~,~~\cfrac{0}{2} \right)\implies (-1~,~0)$

Triangle A has side lengths 3, 4, and 5. Triangle B has side lengths 6, 7, and 8.

Answer:

side lengths are not proportional
6, 8, 10

Step-by-step explanation:

1. The triangles are not similar because the ratios of side lengths are not the same:

3 : 4 : 5 ≠ 6 : 7 : 8

2. We can make the ratios be the same by multiplying the side lengths by a common value, such as 2:

3 : 4 : 5 = 6 : 8 : 10

If triangle B had side lengths of 6, 8, 10, then it would be similar to triangle A.

What is 1/10 + 50/100?

erastovalidia [21]

Answer:

$\large\boxed{\dfrac{3}{5}=0.6}$

Step-by-step explanation:

$\bold{METHOD\ 1:}\\\\\dfrac{1}{10}+\dfrac{50}{100}=\dfrac{1}{10}+\dfrac{50\!\!\!\!\diagup}{100\!\!\!\!\diagup}=\dfrac{1}{10}+\dfrac{5}{10}=\dfrac{1+5}{10}=\dfrac{6}{10}=\dfrac{6:2}{10:2}=\dfrac{3}{5}\\\\\bold{METHOD\ 2:}\\\\\text{Convert the fractions to decimal:}\\\\\dfrac{1}{10}=0.1\\\\\dfrac{50}{100}=0.50=0.5\\\\\dfrac{1}{10}+\dfrac{50}{100}=0.1+0.5=0.6$
