Jasmine invests 2658 in a retirement account with a fixed annual interest rate of 9% compounded annually what will the account balance be after 4 years

Answers

Without making a function out of it, all you need to do is the initial amount 2658$ x 1.09 (1,09 is like adding 0,09 to the total amount 1,00. Which, in % is adding 9% to the total amount 100%.)
= 2897.22$

Since it is compounded every year, you redo the same operation but on the new higher sum you just got.

In total, after 4 years you will have 3751,98$

The budget for a middle school dance is $750. Food and decorations cost $175. The DJ charges $75 per hour plus a one-time business fee of $125?
What is the maximum number of hours the school can have the DJ play at the dance?

Answers

Answer:

The DJ can play at the dance for 6 Hours

Step-by-step explanation:

1. Add the decorations and food plus the additional fee of $12

$175+ $125= $300

2. Subtract the budget and the total so far

750-300= 450

3. Get the amount owed per hour to DJ and divide by the new budget

450/75= 6

The DJ can play at the dance for 6 hours

Have a good day!

Suzanne, Latisha, and Morgan measure their heights. Suzanna is 0.8 times the height of Latisha, and Morgan is 1.09 times the height of Latisha. Who is the tallest? Who is the shortest?

Answers

Answer:

Tallest = Morgan

Shortest = Suzanna

Step-by-step explanation:

Assuming Latisha = 1

0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.

1.09 is more than 1, Morgan is taller than Latisha.

Morgan is tallest and Suzanna is shortest, Latisha in the middle.

b-7=12

Answers

Answer:

[tex]b = 19[/tex]

Step-by-step explanation:

1) Add 7 to both sides.

[tex]b = 12 + 7[/tex]

2) Simplify 12 + 7 to 19.

[tex]b = 19[/tex]

Therefor the answer is, b = 19.

Answer:

Sample Response

Step-by-step explanation:

Use the inverse operation to isolate the variable. Undo the subtraction of 7 by adding 7 to each side of the equation. – 7 + 7 = 0, and 12 + 7 is 19. The solution is b = 19. Check the solution by substituting 19 for b in the original equation, and then simplify. 19 – 7 is 12 and 12 = 12 is a true statement, so 19 is the solution.

four thousand three hundred twenty-one ten thousandths as a decimal

Answers

Answer:

.4321

Step-by-step explanation:

move the decimal to the left four times

We want to write four thousand three hundred twenty-one ten thousandths as a decimal.

The number is:

4321.010

To do it, we need to understand what each place value represents, where the place values are the place of each digit in reference to the decimal point.

The first digit at the left of the decimal point represents the units.The second digit at the left of the decimal point represents the tens.The third digit at the left of the decimal point represents the hundreds.The fourth digit at the left of the decimal point represents the thousands.

And for the right we have:

The first digit at the right of the decimal point represents the tenths.The second digit at the right of the decimal point represents the hundredths.The third represents the thousandths.

Of course, it continues in both ways, but this is enough to write our number.

We have:

"four thousand..."

Then the fourth digit at the left is a 4.

"... three hundred..."

The third digit is a 3.

"...twenty-one..."

The second digit is a 2, and the first is a 1.

For the right side, we do not have tenths, so the first digit at the right is a zero.

And "...ten thousandths"

We have a "10" in the second and third digits at the right of the decimal point.

Then our number is:

4321.010

4k + 6k + 5 +10 = 115

A rectangular chocolate bar is made of equal squares. Irena breaks off two complete strips of squares and eats the 12 squares she obtains. Later, Jack breaks off one complete strip of squares from the same bar and eats the 9 squares he obtains. How many squares of chocolate are left in the bar?

Answers

Answer:

There are three more square chocolates left

Step-by-step explanation:

We know that Irena breaks off 2 complete strips and eats 12 meaning each strip had 6 squares. Jack breaks off 9. So if we add all the squares into rows of 6, we get four strips of chocolate from the beginning. Since Jack and Irena obtained 21 chocolate squares altogether, we have 3 chocolate squares that are remaining. I hope this helps ;)

The number of Squares of chocolate left in the bar is; 15 squares

What is the amount of squares left?

A square has 4 equal sides and since one row contains 6 squares because irena ate 2 complete rows that had 12 squares.

It means that each of the vertical height must also contain 6 squares as well.

Now, two rows are gone and so we now have 4 rows with vertical height of 4 squares. That is 24 squares left.

Now, Jack ate 9 squares and so;

Amount of squares left = 25 - 9 = 15
