Answer:
Step-by-step explanation:
Number of candles =(total volumes used by the company)/(volume of one candle)
volume of one candle =5cm*2cm*12cm=120cm^3
hence number of candles =5040/120
, ,=42candles
Answer:
First derivative the equation
39x²-318x-412=0
then use the quadratic formula
then x = 9.29 or x = -1.14
Answer:
31
Step-by-step explanation:
time is tricky due to the 60 minute interface. In those questions add to the lower number until you hit a rounded number.
Fortunately you don't need to use this in this problem, and can just subtract 58-27 to get 31
Answer:
The correct solution is "$1618.79".
Step-by-step explanation:
The given values are:
Home price,
= $300,000
Down payment,
= 10%
Mortgage,
= $270,000
Rate,
r = 6%
Time,
t = 30 years
As we know,
⇒ ![PV=P[\frac{1-(1+r)^{-n}}{r} ]](https://tex.z-dn.net/?f=PV%3DP%5B%5Cfrac%7B1-%281%2Br%29%5E%7B-n%7D%7D%7Br%7D%20%5D)
On substituting the values, we get
⇒ ![270 000= P[\frac{1-(1+\frac{6}{1200} )^{-12\times 30}}{\frac{6}{1200} } ]](https://tex.z-dn.net/?f=270%20000%3D%20P%5B%5Cfrac%7B1-%281%2B%5Cfrac%7B6%7D%7B1200%7D%20%29%5E%7B-12%5Ctimes%2030%7D%7D%7B%5Cfrac%7B6%7D%7B1200%7D%20%7D%20%5D)
⇒
