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
Answer:
29,750
Step-by-step explanation:
Each year the population is multiplied by 100% + 4% = 1.04. We want to repeat that multiplication 15 times, once for each of the 15 years. An exponent is what we use to signify (and compute) repeated multiplication. The population will be ...
16,519 × 1.04^15 ≈ 29749.8 ≈ 29,750
Jean and Jonathans' age illustrate arithmetic sum, and the sum of their ages in three years time is x + y + 6
<h3>How to determine the sum of their ages?</h3>
Currently, their ages are:
Jean = x
Jonathan = y
In 3 years, their ages would be:
Jean = x + 3
Jonathan = y + 3
So, the sum of their ages is:
Sum = x + 3 + y + 3
Evaluate
Sum = x + y + 6
Hence, the sum of their ages in three years time is x + y + 6

Answer:
$750 cost of the washer.
Step-by-step explanation:
3x+x=1,000
4x=1,000
x=1,000/4
x=$250 cost of the dryer.
3*250=$750 cost of the washer.
Proof:
750+250=1,000
1,000=1,000
