Answer:

<h2>8:12</h2>

Step-by-step explanation:

Ok so the starting ratio is 4:6

It is 20 members  last year and 25 member the next year.

LAST: 20 THIS YEAR:25

When u use the ratio of 4:6 IN 25 students, u get

8:12 LAST year.  

You can check because 8 + 12 = 20, or the total number of students.

Solve for the indicated angle to the nearest tenth of a degree.<br> o<br> 18<br> 25
Sonbull [250]

Answer:

\theta=54.2^\circ

Step-by-step explanation:

<u>Right Triangles</u>

The ratios of the sides of a right triangle are called trigonometric ratios.  Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

The tangent ratio is defined as:

\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}

The opposite side is 25 and the adjacent side is 18, thus:

\displaystyle \tan\theta=\frac{25}{18}=1.389

The angle is calculated by using the inverse tangent function:

\theta=\arctan 1.389

\boxed{\theta=54.2^\circ}

How do you solve algebraically 8x^2=18

x =  + \frac{ \sqrt[]{3} }{ \sqrt[]{2} }
BTW the plus sign is supposed to have this sign underneath it _
Good luck.
