Answer:
n= 5.57 years
Step-by-step explanation:
Giving the following information:
your final balance on an investment of 270$ invested at 10% was $459.00
<u>To calculate the time passed between values, we need to use the following formula:</u>
n= ln(FV/PV) / ln(1+i)
FV= 459
PV= 270
i= 0.1
n= ln(459/270) / ln (1.1)
n= 5.57 years
Answer:
56x-38
Step-by-step explanation:
2(8x+9)-8(7-5x)
16x+18
-8(7-5x)
-56+40x
16x+18-56+40x
Add all like terms
56x-38
Answer:
HA HA HA!!!
Step-by-step explanation:
I am sorry that you feel that way. Maby you should go listento music it help me when I was depresed. Not cristen music though. I love the meem.
A: We want to select one person who works out three days a week. Our probability is simply 12/80 ~~ 15%
B: At least 4 days a week means 4 days, 5 days, or 6 days.
Hence, we have: (9 + 20 + 8)/80 = 46%
C: At least once a week.
Let's find out how many DO NOT work out and subtract that from our sample space. This means they must work out at least once a week.
(80 - 15)/80 = 81%
C = 220T + 1890.
Solve the equation for T.
220T = C - 1890
T = C/220 - 8.6
The steel produced is expected to be sold at a price of $310 per ton.
310 $/ton is a rate or slope. Write a linear equation where x is tons of steel produced and y is selling price of the steel.
y = 310x
Write and solve an equation to find the amount of steel produced if the selling price is equal to the cost of production.
* Here, note that the cost of production and tons of steel in the first equation is in the millions. The equation we just wrote for the selling price was in x tons of steel. This only matters in regards to the units you specify because; million/million = 1
The unit multiplier of all variables must be specified as same. Either everything is in millions or not.
Here, I'll leave everything in millions, change x (tons of steel) to T (mill tons steel) and "y" to "S" in million dollars selling price.
S = 310T
Set equal to Cost equation.
220T + 1980 = 310T
Solve for T, million tons of steel produced.
1980 = 310T - 220T
1980 = 90T
T = 1980/90
T = 22 million tons steel produced
