A tank that is 40% full contains 648 gallons of water. How much water is in the tank when the tank is at full capacity (100%)?

Answers

Answer: 1620 gallons of water

Step-by-step explanation:

Let the water that is in the tank when the tank is at full capacity be represented by x.

Therefore, 40% of x = 648

40% × x = 648

40/100 × x = 648

0.4 × x = 648

0.4x = 648

x = 648/0.4

x = 1620

The answer is 1620 gallons

Step-by-step explanation:

Lydia invested $83,000 in an account paying an interest rate of 6.7% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $210,100?

Answers

Answer:

14

Step-by-step explanation:

 

The required time for Lydia's account to reach $210,100 is 13.9 years.

What is compound interest?

Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.

First, convert R as a percent to r as a decimal

r = R/100

r = 6.7/100

r = 0.067 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.067/12)] )

t = ln(210,100/83,000) / ( 12 × [ln(1 + 0.0055)] )

t = 13.9 years

Thus, the required time for Lydia's account to reach $210,100 is 13.9 years.

The total cost of the tablet is $840

Step-by-step explanation:

Here, we want to calculate the total cost

Let the total cost be $x

From the ratio, the total ratio is 3 + 4 + 1 = 8

so,;

3/8 * x = 315

3x = 8 * 315

x = 8/3 * 315

x = 8 * 103

x = 840
