Question 1

allochka39001 [22]

Answer:

Step-by-step explanation:

Perimeter of quarter circle = r + r + $\frac{1}{4}*2*\pi *r$

$= 10 + 10 + \frac{1}{4}*2*3.14*10\\\\= 10 + 10 + 3.14*5\\\\\\= 10 + 10 + 15.70\\\\= 35.70 cm$

2) d = 2*10 = 20 cm

Perimeter of semicircle = diameter + (1/2) * circumference of circle

$= 20 + \frac{1}{2}* 2*\pi *r\\\\= 20 + \frac{1}{2}*2*3.14*10\\\\= 20 + 3.14*10\\\\= 20 + 31.4\\\\= 51.40 cm$

3) Perimeter of three-quarter = r + r + (3/4)* circumference of circle

$= 10 + 10 + \frac{3}{4}*2*\pi *r\\\\= 10 + 10 + \frac{3}{4} * 2 * 3.14 * 10\\\\= 10 + 10 + 3 * 3.14 * 5\\\\= 10 + 10 + 47.1\\\\= 67.1 cm$

Bethany, Lauren, Amanda, and David all meet at a family reunion. They are comparing their ages. They have found that Lauren is 1

tekilochka [14]

Lauren =l
David=d
Bethany's =x
Amanda =y
l=x+13
d=y+11
lx=2y
(x+13)x=2y
 $2y=x^2+13x$
$y= \frac{1}{2}(x^2+13x)$
or
$y= \frac{x^2}{2}+ \frac{13}{2}x$
(x-20)(l-20)=d
(x-20)(x+13-20)=y+11 
 $y+11=(x-20)(x-7)$
$y+11=x^2-27x+140$
$y=x^2-27x+129$
so I believe its b
Hope this helps :)
