Answer:

V = 10 + 4t

Step-by-step explanation:

To find the equation, look at the pattern:

  • 10 gallons + 4 gallons = 14 gallons after 1 minute
  • 10 + 4 + 4 = 18 after 2 minutes
  • 10 + 4+4+4 = 22 after 3 minutes.

The pattern is 10 + 4 (t) = V

At what rate of interest would rs 1800 amount to rs 2500 in 2 years
Romashka [77]

Interest formula: A = P(1 + rt)

Solving for r (Rate): r = (1/t)(A/P - 1)

Rate = (1/2)(2500/1800 - 1) = (1/2)(25/18 - 1) = (1/2)(7/18) = 7/36 ≈ 0.194

Rate = 0.194% per annum

Lyn invested $7,000 into a investment paying 3% interest, compounded semi-annually, twice a year. After five years, how much wou
gayaneshka [121]

Answer:

Option B.) $8,123.79

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=5\ years\\ P=\$7,000\\ r=0.03\\n=2  

substitute in the formula above  

A=\$7,000(1+\frac{0.03}{2})^{2*5}  

A=\$7,000(1.015)^{10}=\$8,123.79
