James deposited $575 into a bank account that earned 5.5% simple interest each year.If no money was deposited into or withdrawn from the account, how much money was in the account after ​ ​ 2 1/2​ ​ years?

Round your answer to the nearest cent.

Answers

Answer 1
Answer: Hi there!
So first we should find what 1% of 575 is. To do that de divide it by 1 and get 5.75. Since he gets 5.5 simple interest per year, we multiply 5.75 by 5.5. We get 31.625. This asks how much after 2 1/2 years, so lets multiply 31.625 by 2.5 and get 79.0625. Then add that amount to 575 and end out with 654.0625. But this question asks us to round to the nearest cent, and after rounding we have 654.06. So, after 2 1/2. years he has $654.06! Hope this helps.

rachel uses grid paper to plan a mural to paint at her school. the design will be made of two connected rectangles. the larger rectangle will have an area between 35 square feet and 45 square feet. the smaller rectanglewill have an area between 10 square feet and 20 square feet. Draw and label a diagram to show what Rachel could plan. Explain how to find the total area.

The area of a rectangle is found by multiplying the base times the height. A rectangle with an area represented by 12x2 + 6x – 8 has a height of 4x. What is the base of the rectangle? 3x + – 3x2 + – 3x + – 3x + –

What is a Cartesian plan?

Answers

I'm assuming you mean Cartesian plane. It is the same as a coordinate plane. There are two perpendicular lines with an x (horizontal) and y (vertical) axis. 
it is kinda like she said There are two perpendicular lines with an x horizontal and y vertical axis. i think that is in your math book as well 

I need help.. 7k/8-3/4-5k/16=3/8

seven "k" over eight minus three fourths minus five "k" over sixteen equals three eighths

Answers

This is exactly like the one with the 'n's that you posted yesterday.
I guess you didn't get enough help on that one to understand it.

7k/8 - 3/4 - 5k/16 = 3/8

3/4 is the same as 6/8.
Add it to each side of the equation:

7k/8         - 5k/16 = 9/8

Multiply each side by 16 :

14k - 5k = 18

Add up the 'k's on the left side:

9k = 18

From this point, you can proceed directly to the numerical value of 'k'
if you need it.

In your question, you said you need help, and I showed you how to
strip the problem down so that the only thing left is ' k = something '.
Giving you the answer is no help.  Nobody actually needs the answer.
since 16 is their least common multiple you can get rid of all of the fractions by multiplying each fraction by 16:

16(7k/8)-16(3/4)-16(5k/16)=16(3/8)
 
14k-12-5k=6
            9k=6+12
            9k=18
              k=18/9
              k=2

Which of the following graphs has a slope that indicates an object whose velocity is zero

Answers

Answer:

The correct option is 1.

Step-by-step explanation:

We need to find a graph that indicates an object whose velocity is zero.

Velocity is the change in displacement with respect to time.

Let d represents displacement and t represent time.

v=\frac{\text{Change in displacement}}{\text{change in time}}

Velocity is 0.

0=\frac{\text{Change in displacement}}{\text{change in time}}

It means the slope of line must be 0.

A horizontal line has slope 0.

In option 1, the graph represents a line whose slope is 0. It means displacement is 0 for any interval of time. So, velocity is 0.

Therefore the correct option is 1.

Answer:

The horizontal line.

Step-by-step explanation:

A horizontal line has a slope of 0. This would be expected on a graph where time is the x axis and distance is the y axis. Time would elapse but the distance would not change.
