x - 1 x + 1
------ = --------------
x + 3 x + 6
if x = 9
8/ 12 = 10/15
12 (10) = 8(15)
120 = 120
so
answer is 9 (last choice)
We are given the functions:
<span>S (p) = 40 + 0.008 p^3 --->
1</span>
<span>D (p) = 200 – 0.16 p^2 --->
2</span>
T o find for the price in which the price of supply equals
demand, all we have to do is to equate the two equations, equation 1 and 2, and
calculate for the value of p, therefore:
S (p) = D (p)
40 + 0.008 p^3 = 200 – 0.16 p^2
0.008 p^3 + 0.16 p^2 = 160
p^3 + 20 p^2 = 20,000
p^3 + 20 p^2 – 20,000 = 0
Calculating for the roots using the calculator gives us:
p = 21.86, -20.93±21.84i
Since price cannot be imaginary therefore:
p = 21.86
Answer:
$18.50
Step-by-step explanation:
In the example before 61 messages = $6.10 or rounding to the tenths place 6.1. If you do the same with 185, you get 18.5 or 18.50
You can make an equation.
Let x=oranges
p=plums
n=apples
n= 3p + 5x
So basically we know 1 Apple means Sam will pack 3 plums and 5 oranges
To get 3n which means 3 apples we have to multiply the whole equation by 3
(n= 3p + 5x) x3
3n=9p+15x
So Sam will also put 9 plums and 15 oranges if he puts 3 apples in the box
Answer:
The sports car, because it has less mass and therefore less inertia
Step-by-step explanation:
When an object has less inertia it is easier to be put into and out of motion, and a sports car would obviously weigh less than a van.
