I really need the answers please help asap
DanielleElmas [232]

Step-by-step explanation:

In a straight line theres 180 degrees and where x is you can tell its an X lines the opposites will be the same.

First you need to work out the triangles 180-122=58 and a triangle is 180 degrees so

58+40=98 180-98=82°

now working out the other triangle.

180-82=98, 43+98=141

180-141=39

and because the opposites will end up the same x=39°

Alina [70]

Answer:

-1 5/28

Step-by-step explanation:

-3/7 + (-3/4)

Get a common denominator of 28

-3/7 *4/4 = -12/28

-3/4 *7/7 = -21/28

-12/28 + -21/28

-33/28

-28/28 - 5/28

-1 5/28

A population of 40,000 decreases by 3.1% each year. what is the approximate population in 4 years
coldgirl [10]

\bf \textit{Amount of Population Decay} \\\\ A=Pe^{-rt}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &40000\\ r=rate\to 3.1\%\to \frac{3.1}{100}\dotfill &0.031\\ t=\textit{elapsed time}\dotfill &4\\ \end{cases} \\\\\\ A=4000e^{-0.031(4)}\implies A=40000e^{-0.124}\implies A=\cfrac{4000}{e^{0.124}} \\\\\\ A\approx 35335.194\implies \stackrel{\textit{rounded up}}{A\approx 35335}
