61. |190 - 210| + |19 - 21| + x = 100

1 answer:

3 0

Hello,

|190-210|+|19-21|+x=100
==>|-20|+|-2|+x=100
==>20+2+x=100
==>x=100-22
==>x=78

Thus there is a mistake in your question !

Estimate the percentage of never married American female ages from 25 to 29 in 2010

Andru [333]

in 1980 it was about 20%

in 1990 it was about 30%

about a 10% increase

in 2000 it was just under 40% so almost a 10% increase

so for estimating you can say it is increasing by about 10% every 10 years

so in 2010 you can estimate about 50% are unmarried

Give the radian measure of an angle drawn in standard position that corresponds with the ray containing the coordinate point (−1

Sergeu [11.5K]

Answer:

The radian measure of the angle drawn in standard position that corresponds with the ray containing the coordinate point $(-12, -3\sqrt{2})$ is approximately $1.108\pi$ radians.

Step-by-step explanation:

With respect to origin, the coordinate point belongs to the third quadrant, which comprises the family of angles from $\pi\,rad$ to $\frac{3\pi}{2}\,rad$ . The angle in standard position can be estimated by using the following equivalence:

$\theta = \pi\,rad + \tan^{-1} \left(\frac{3\sqrt{2}}{12} \right)$

$\theta \approx \pi \,rad + 0.108\pi \,rad$

$\theta \approx 1.108\pi\,rad$

The radian measure of the angle drawn in standard position that corresponds with the ray containing the coordinate point $(-12, -3\sqrt{2})$ is approximately $1.108\pi$ radians.
