Do not round any intermediate computations, and round your answer to the nearest hundredth. If necessary, refer to the list of financial formulas. years X - ?​

Answers

Answer:

10.94 years

Step-by-step explanation:

We're gonna use the compound interest formula: P = A(1 + r/n)ⁿˣ

P = Final amount (6500)

A = Starting amouint (5000)

r = rate (0.024)

n = number of times applied (12)

x = number of years

6500 = 5000(1 + 0.024/12)¹²ˣ

First, divide both sides by 5000

(1 + 0.024/12)¹²ˣ = 6500/5000 = 1.3

Then solve the equation inside the parenthesis

1.002¹²ˣ = 1.3

Take log₁.₀₀₂ from both sides

12x = log₁.₀₀₂(1.3)

12x = 131.3133

Finally divide both sides by 12

12x/12 = 131.3133/12

x = 10.942775

Maria is training for a triathlon. Yesterday, she rode her bike for eight and two-thirds miles in two-thirds of an hour. If Maria continues to rides at the same rate, how far will she ride in one hour? help plzz

Answers

(8 2/3) / (2/3) = x / 1....8 2/3 miles to 2/3 hr = x miles to 1 hr
cross multiply
(2/3)(x) = (8 2/3)(1)
2/3x = 26/3
x = 26/3 * 3/2
x = 26/2...which equals 13....she will ride 13 miles in 1 hr

Maria's rate is 13 miles per hour. If she continues to ride at the same rate, she will ride 13 miles in one hour.

We have,

Maria's rate can be calculated by dividing the distance she rode by the time she took.

Rate = Distance / Time

Yesterday, she rode 8 and two-thirds miles in two-thirds of an hour:

Rate = (8 + 2/3) miles / (2/3) hour

First, let's convert the mixed number (8 + 2/3) to an improper fraction:

8 + 2/3 = (8 * 3 + 2) / 3 = 26/3

Now, plug in the values:

Rate = (26/3) miles / (2/3) hour

When you divide fractions, you can multiply the first fraction by the reciprocal of the second fraction:

Rate = (26/3) * (3/2) miles/hour

Rate = (26/2) miles/hour

Rate = 13 miles/hour

Thus,

Maria's rate is 13 miles per hour. If she continues to ride at the same rate, she will ride 13 miles in one hour.

The perimeter of a rectangle is 44 inches. If the length is 1 more than twice the width, what is the length and width?

Only algebraic solution is accepted

Answers

Answer:

The width is 7 inches, the length is 15 inches

Step-by-step explanation:

If the width is x inches, then the length is 2x+1 inches. Since the perimeter of a rectangle is 2 times the width plus 2 times the length, the perimeter will be 2x+2(2x+1), which simplifies to 6x+2. Since the perimeter is 44 inches, we get the equation 6x+2=44, which makes x=7. So, the width is 7 and the length is 15.

What is interest ?The cost of borrowing money is called interest, and it is typically stated as a percentage, such as an annual percentage rate (APR).Lenders may charge interest to borrowers for using their funds, or borrowers may charge interest to lenders for using their funds.Interest is frequently regarded as compound interest or simple interest (based on the principal amount) (based on principal and previously-earned interest).Credit cards, mortgages, auto loans, personal loans, savings accounts, and penalty assessments are all frequently linked with interest.The macroeconomic policy set by the Federal Reserve's federal funds rate has a significant impact on interest rates.

What is the equation of circle?

The equation of the circle with center (h, k) and radius 'r' is, [tex](x-h)^2 + (y-k)^2 = r^2[/tex]

For given question,

Addison and Kelsey are running on a path modeled by [tex]x^2 + y^2 - 12x - 8y - 309 = 0[/tex]

This means, they are running on a circular path.

By completing the squares, the equation is:

[tex]\Rightarrow x^2 -12x + 36+ y^2 - 8y +16 = 309 + 36+16\\\\\Rightarrow (x-6)^2+(y-4)^2=361\\\\\Rightarrow (x-6)^2+(y-4)^2=19^2[/tex]

This equation represents the circle with center (6, 4) and radius = 19

The maximum distance between the runners is the diameter of the circle.

diameter = 2 × radius

diameter = 2 × 19

diameter = 38 meters

Therefore, the maximum distance between the runners at any given time is 38 meters.

Answers

Answer:

5)  35 / 100 = X / 74      X = 2590 / 100 = 25.9

or .35 * 74 = 25.9

X = 7800 / 95 = 82.1 %

or X = 78/95 * 100 = 82.1 %

X = 2800 / 60 = 46.7

Or .6 * X = 28

X = .28 / .6 = 46.7

The price of a stock went up by $1.20 on Monday, down by $2.30 on Tuesday, down by $1.00 on Wednesday, down by 1.80 on Thursday, and up by $.40 on Friday. What is the mean change of the stock price for those 5 days

Answers

Answer:

The mean change of the stock price of those 5 days is $1.34.

Step-by-step explanation:

First let's list the differences then find the mean.

1.20, 2.30, 1.00, 1.80, 0.40

Now we add up all of the numbers and divide by how many numbers there are.

Mean = 1.34

The mean change of the stock price of those 5 days is $1.34.

The stock cost changes summed to -$3.50. Partitioning by 5 days gives the Mean change of -$0.70 for the period.

What is the mean change of the stock price for those 5 days?

To discover the mean change in the stock cost over those 5 days, you would like to calculate the overall alter in cost and after that isolate it by the number of days.

Given cost changes:

Monday: +$1.20

Tuesday: -$2.30

Wednesday: -$1.00

Thursday: -$1.80

Friday: (+$0.40)

Total change = (+$1.20 + -$2.30 + -$1.00 + -$1.80 + +$0.40)

Total change = -$3.50

Number of days = 5

Mean change = Add up to alter / Number of days

Mean change = -$3.50 / 5

Mean change = -$0.70

So, the Mean change of the stock cost over those 5 days is -$0.70.

•The independent variable is the variable or the thing that the scientist/creator changes.

•the dependent variable is what we measure at the end and it depends on the independent.

•Controlled group/variable is the thing that should be constant in order to have an accurate results and it never changes even if anything changes in the experiment.

1. Controlled: Number of stacks of paper

Amount of time

Amount of juice

Number of workers

2. Independent: Amount of juice given to workers

3. Dependent: Number of stacks at the end

•Explanation that helps with your conclution: The juice has nothing to do with how much stacks the workers finish. It depends on how each worker is handled to do their work even when on pressure, also. The juice may be a distraction to the workers because they drink it while working so they're consuming their energy without the help of the juice. Lastly, maybe some of the workers didn't drink the same amount of juice while working on finishing the stacks.

4. CONCLUSION: Group B had much higher results than Group A in 24% Even though they didn't drink the juice. Shows that workers do their job more efficiently and faster when their not distracted while working.

5. (a) Smith should make sure that the 50 workers drink the same amount of juice before they start their work and also make sure that both groups start doing their task at the same time and finish at the same time, for accurate changes.

The answer is 4.60977222865 rounded to however much it asks you to round.

We are given:
x (-4, 3)
y (2, -1.5)
z (4, -1)
A (3, 3)

And we are trying to find the hypotenuse of triangle YZA because that’s what the line from “point A to XZ” is.

The Pythagorean Theorem is a^2 + b^2 = c^2

We can use it to find the distance between any two points. If we imagine 2 more lines, one going straight down from the higher point, and the other one going horizontally from the lower point until it meets the vertical line. We have another triangle.

The length of the horizontal segment of a triangle is just the difference of. the x values. And the length of the vertical segment is just the difference of their y values.

So we have
(x2 - x1)^2 + (y2 - y1)^2 = c^2

Simplified:
sqrt((x2 - x1)^2 + (y2 - y1)^2) = c

Segment YZ =
sqrt((x2 - x1)^2 + (y2 - y1)^2) = c
sqrt((4 - 2)^2 + (-1 - -1.5)^2) = c
sqrt(4 + .25) = c
sqrt(4.25) = c
2.06155281281 = c

The length of YZ is 2.06155281281.

Now we need to know segment ZA.
Segment ZA =
sqrt((x2 - x1)^2 + (y2 - y1)^2) = c
sqrt((3 - 4)^2 + (3 - -1)^2) = c
sqrt(1 + 16) = c
sqrt(17) = c
4.12310562562 = c

The length of segment ZA is 4.12310562562.

Finally:
AZ^2 = YZ^2 + ZA^2

AZ^2 = (2.06155281281)^2 + (4.12310562562)^2

AZ^2 = 4.25 + 17

AZ^2 = 21.25

AZ = sqrt(21.25)

AZ = 4.60977222865
