In the figure below, BD and EC are diameters of circle P.
What is the arc measure of AE in degrees?

Step-by-step explanation:

We know by given

According to the given circle,

, by supplementary angles.

Replacing each value, we have

Now, the angle EPA subtends the arc AE, and this angle  is a central angle. So, according to its defintion, the arc AE is equal to its central angle.

Therefore, the answer is 27°

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
