Answer:
The ending balance is of $790.1.
Step-by-step explanation:
Compound interest:
The amount of money earned after t years, in compound interest, is given by:
In which A(0) is the initial amount of money and r is the interest rate, as a decimal.
$600 that earns 3.5% compound interest over 8 years
This means, respectively, that:
So, the formula is:
Ending balance:
The ending balance is:
The ending balance is of $790.1.
Answer:
<em>x</em> = 25
Step-by-step explanation:
First turn this into an equation:
times <em>x</em> = 20
Now divide both sides by . You can't divide by a fraction, instead you multiply by flipping the fraction. So now you're multiplying both sides by .
20 times 5 = 100. Next you divide . This is equal to 25. You have completed the equation and now have the answer:
<em>x</em> = 25
Have a great day!
12 units i think since it is from one point to another
Answer:
The big container holds 30 gallons and the small container holds 20 gallons
Step-by-step explanation:
Let
The big container = x
Small container = y
The big container can hold 10 gallons less than twice the small
x = 2y - 10
Total gasoline in both containers = 50 gallons
x + y = 50
Substitute x = 2y - 10 into the equation
2y - 10 + y = 50
3y = 50 + 10
3y = 60
Divide both sides by 3
y = 60 / 3
= 20
y = 20 gallons
Recall,
x + y = 50
x + 20 = 50
x = 50 - 20
= 30
x = 30 gallons
The big container holds 30 gallons and the small container holds 20 gallons
