S(p) = 400 - 4p + 0.00002p^4
D(p) = 2800 - 0.0012p^3
S(p) = D(p)
400 - 4p + 0.00002p^4 = 2800 - 0.0012p^3
0.00002p^4 + 0.0012p^3 - 4p - 2400 = 0
p = $96.24
Answer:
1 and 3/8 of pizza
Step-by-step explanation:
5/8 + 3/4
3/4 x 2 to get the same denominator as 5/8
5/8 + 6/8 = 11/8
11/8 = 1 3/8
The solution
m = s + 5
<span>m - 4 = (3s) - 3 </span>
<span>(s + 5) - 4 = 3s - 3 </span>
<span>s + 1 = 3s - 3 </span>
<span>s = 3s - 4 </span>
<span>-2s = -4 </span>
<span>s = 2 </span>
<span>m = 7 </span>
<span>Check this: </span>
<span>m - 4 = 3s - 3 </span>
<span>7 - 4 = 3(2) - 3 </span>
<span>3 = 6 - 3 </span>
<span>3 = 3 </span>
<span>So Sandy is 2 and Megan is 7.</span>
Circumference = 2*pi*radius.
Pi = 3.
2 * pi * r = 96
2 * 3 = 6.
2 * 3 * r = 96
Find r: 96/6 = 16.
2 * 3 *16 = 96.
r = 16.
Answer:
2.1 miles
Step-by-step explanation:
you can see a drawing of the situation in the attached picture (you need to draw all the places mentioned and the distance between them),
this way we can form a right triangle between the school and the hospital with measures of sides: 1.7 and 1.2 miles
and the green line is the straight line between the school and the hospital, so you need pythagoras to find the value:
rounding to the nearest tenth:
2.1 miles
