Answer:

10+3pi

Step-by-step explanation:

The perimeter of of the shaded region is

AC+CT+marcSBT+SA

*Finding AC

The diagonals of a rectangle are equal is measurement. Since RB is a radius of the circle, then RB is 6. Since AC and RB are both diagonals of the rectangle, then AC is also 6.

*Finding CT

CT=RT-RC where RC is the width of the rectangle

Also RT is a radius so we have that

CT=6-RC

*Finding marcSBT

The circumference of a whole circle is 2pi*r.

We have a quarter of this with r=6.

1/4*2pi(6)

1/4*12pi

3pi

*Finding SA

SA=RS-AR

RS is a radius of the circle and AR is the length of the rectangle.

So we have that this can be rewritten as

SA=6-AR

Let's put these parts together:

6+6-RC+3pi+6-AR

Simplifying:

18-RC-AR+3pi

18-(RC+AR)+3pi

18-8+3pi (Remember length plus width equal 8)

10+3pi

A woman is now 30 years older than her son. 15 years ago, she was twice as old. What are the present ages of the woman and her s
Paladinen [302]

Answer:

75 and 45

Step-by-step explanation:

woman's age= w

son's age= s

--------------

  • w=s+30
  • w-15=(s-15)*2 ⇒ w-15=2s-30 ⇒ w=2s- 15

comparing the two above:

  • s+30=2s-15  ⇒ s= 45 ⇒ w= 75
