Answer:
It decreases by 7.5 psi
Step-by-step explanation:
:)
<span>The answer should be set up like so:
3125 = 3200*(d)^3
3125/3200 = d^3
3-root (3125/3200) = d
d = 0.992125657...
1 - d = 0.007874...
Therefore it depreciates at about 0.8% monthly
To find the depreciation 6 months from now, or 9 months from the beginning:
v = 3200 (d)^9
= 2980.232239...
So after 9 months the car would be about $2980.23</span><span>

Answer:
x=-3 and y= -6
Step-by-step explanation:
we have
6=-4x+y and -5x-y = 21
6+4x=y we substitute y in the second equation
-5x-(6+4x)=21
-9x-6=21
-9x=27
x=-3
we substiture x in the second
-5(-3)-y =21
15-y=21
15-21=y
y=-6
<span>250*(2*60)=30000
125*(3*60)=22500
22500+30000=52500
52500:((3+2)*60)=175 (</span><span>words per minute)</span>
Answer:
14
Step-by-step explanation:
Firstly, we need to subtract the amount she earned from walking the dog ($9.00) from the end total ($16.00). This leaves us with $7.00.
Since she spent exactly<em> </em><em>half</em> of her weekly allowance, we must multiply the remaining $7.00 by 2. This leaves us with our final answer of $14.00.
