Kira opened a savings account with $9000 and was paid simple interest at an annual rate of 3%. When Kira closed the account, she was paid $1620 in
interest. How long was the account open for, in years?
If necessary, refer to the list of financial formulas.

Answers

Answer 1

Answer:

5.6 years

Step-by-step explanation:

N =  A (1 + increase) ^n

Where N is future amount, A is initial amount, increase is percentage increase/decrease, n is number of mins/hours/days/months/years.

if the amount of interest was 1620, then she had a total of 9000 + 1620

= 10 620.

10 620 = 9000 (1 + 0.03)^n

(1 + 0.03)^n = 10620/9000 = 1.18.

take logs for both sides:

log (1.03)^n = log 1.18

n log (1.03) = log 1.18

n = ( log 1.18)/ log (1.03)

= 5.6 years

Answers

Answer:

y=x

Step-by-step explanation:

If we look at this then this is a y=mx+b graph

first lets find the rise/run

so rise = how much it goes up and run = how much it goes right or left

the rise/run of this graph is 1 because each time it goes one up it goes one right.

B= y intercept and the y intercept is 0

So it is y=1x+0 or y=x

answer = y=x

Answers

Answer:

height of b = 280

Step-by-step explanation:

candle b has a height of 280 - 5t, when it comes out of the mold then t=0 so the initial height of b is 280

candle b's height drops by 5 every hour (that's what the -5t part means)

candle a started at 216 and dropped to 192 in 3 hours, so it dropped by 24 in 3 hours so it drops 8 each hour

so candle b starts out taller (280 v. 216) and candle b burns slower (a at 8 per hour and b at 5 per hour), so b will never 'catch up' with a... candle a will be burned out while candle b is still burning

Answers

Answer:A perimeter is the sides of a shape added together.

Step-by-step explanation:

Answer:

The perimeter of a rectangle is the total length of all the sides of the rectangle.

Step-by-step explanation:

The perimeter of a rectangle is the total length of all the sides of the rectangle. We can find the perimeter by adding all four sides of a rectangle. Since opposite sides of a rectangle are always equal, we need to find the dimensions of only two sides to find the perimeter of a rectangle.

If you have a 2 inches by 4 inches rectangle, you would have 2 inches + 4 inches + 2 inches + 4 inches = 12 inches

Three calculators cost as much as seven mugs. Each calculator costs $12 more than each mug. What is the cost of one mug?

To obtain the value of one unknown quantity linear equation in one variable can be formed. The cost of one mug is given as $21.

What is a Linear equation?

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

Given that,

The cost of 3 calculators = The cost of 7 mugs.

The cost of each calculator is $12 more than each mug.

Suppose, cost of each mug be x.

And, cost of each calculator is x + 12.

As per the question the following equation can be made,

7 ×(x + 12) = 3x

=> 7x - 3x = 84

=> 4x = 84

=> x = 21.

Hence, the cost for one mug is $21.

Answers

Step-by-step explanation:

The best way to do this would be to choose a random number of individuals that have bought a frozen fruit drink to survey. Then this same number of individuals should be surveyed in every single shop in the town. This would allow you to gather data from all of the shops and make sure that the sample is completely representative of the population as long as the individuals are chosen completely at random without introducing any external bias to the choice.
