Answer:
width= 223.9 ft
Step-by-step explanation:
perimeter=2(l+w)
948.2=2(250.2+w)
948.2=500.4+2w
948.2-500.4=2w
447.8=2w
w=447.8/2
=223.9 ft
Answer: x - 6 = 15
Step-by-step explanation:
E + r = 27;
e - 9 = 2 x ( r - 9 );
So, e = 27 - r;
Then, 27 -r - 9 = 2r - 18;
18 - r = 2r - 18;
18 + 18 = 2r + r;
36 = 3r
Finally, r = 12 years (Rosa);
e = 27 - 12;
e = 15 years (Emil);
Answer: (f•g)(x) = (15 + x)/x
Explanation:
F(x) = 5/x and g(x) = 3 + x/5
Then (f•g)(x) = 5/x • 3 + x/5
(f•g)(x) = 5/x • 15/5 + x/5
(f•g)(x) = 5/x • (15 + x)/5
(f•g)(x) = 5(15 + x)/5x
(f•g)(x) = (15 + x)/x
The slope of this line is 5/3 so a perpendicular slope would be opposite reciprocal to this or -3/5
