Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.

Answers

Answer 1

Answer:

52 ft

Step-by-step explanation:

area of a square is l x w. all sides are equal so the l = w

A = 169 ft^2 so each side is the square root of 169 which is 13 ft

perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

Perimeter = 13ft × 4 = 52 ft

so:

Answer 2

Answer:

52m

Step-by-step explanation:

Area of the square floor = 169 m²

For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.

So,

Length of each side of floor = √169 = 13m

For a square with each side 's' , its perimeter will be 4s.

Hence ,

Perimeter of the kitchen = 13 × 4 = 52m

The graph represents function 1, and the equation represents function 2:

Function 2
y = 5x + 4
How much more is the rate of change of function 2 than the rate of change of
function 1? (4 points)

Answers

Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.  

5 is the answer.

Chase thought that only 23 people Would come to the banquet but 48 people endd up coming what was his percent error

Answers

Answer:

the percent of people that end up coming as error is 12%

Chase made a miscalculation of 52.08% percent.

What is Percentage Error?

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given that, Chase anticipated that just 23 people would attend the event; however, 48 individuals showed up.

The general formula for percentage error:

Percentage Error(%e) = ((Estimated Number – Actual Number)/ Actual number) x 100.

Hence,

Percentage error done by chase = (23 - 48) * 100/48

Percentage error done by chase = -52.08%

Therefore, the Percentage error done by chase is 52.08%

Renting roller blades costs a flate fee of $5 plus an additional $2.50 per hour. Write a linear equation that models this.

Answers

Answer:

Linear equation : y = 2.50h + 5

Step-by-step explanation:

Given that:

Fee for renting roller blades = $5

Per hour charges = $2.50

Let,

h be the number of hours roller blades were rented

y be the total amount

Total amount = Per hour charges * Number of hours + Flat fee

y = 2.50h + 5

Hence,

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

Where xi is the value of each data and n is the total number of values.

We are given the average weight of n=5 marathon runners:

[tex]\bar x=92[/tex]

Multiplying the formula by n and expanding the sum:

[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]

We are given the weighs of four of the runners:

Diane buys candy that costs $4 per pound. She will spend more than $20 on candy. What are the possible numbers of pounds she will buy?
Use
P
for the number of pounds Diane will buy.
Write your answer as an inequality solved for p.​

Answers

Answer:

12 pounds

Step-by-step explanation:

We know that the candy costs $4 per pound

We also know that he will only spend up to $48

We can represent this as an equation:

4x = 48

Where as x = number of pounds

Solve the equation to find how many pounds he can buy.

4x = 48

Divide both sides by 4

x = 12

This means that Kareem can buy 12 pounds

a football coach is trying to decide: when a team is ahead late in the game, which strategy is better?

• play the "regular" defense.

• play a "prevent" defense that guards against long gains but makes short gains easier
the coach reviews the outcomes of 100 games

compare the probability of winning when playing regular defense with the probability of winning when playing prevent defense. draw a conclusion
based on your results.

Answers

From analysis, it is seen that the probability of winning when playing regular defense is higher than the probability of winning with *prevent* defence.

How to find the probability of Winning?

We will assume that a total of 100 games were reviewed.

50 games used regular defense method.

The remaining 50 games used the prevent defense method.

Out of the 50 regular defense games, 38 were win while 12 games were lose.

Out of 50 prevent defense game, 29 were win, while 21 games were lose.

Thus, the Probability of winning by regular defense is:

P(win | regular) = 38/50

P(win | regular) = 0.76

Probability of winning by playing prevent defense is:

P(win | prevent) = 29/50 = 0.58

From the above analysis we observe that the probability of winning by using the regular defense method is greater than the probability of winning by prevent defense method.

That is 0.76 > 0.58.

Write 9x² - 36x = 4y² + 24y + 36 in standard form
this is a graph of a hyperbola, if this helps.
please include the steps on how you did it
Thank you!

Answers

Answer:

9·x² - 36·x = 4·y² + 24·y + 36 in standard form is;

(x - 2)²/2² - (y + 3)²/3² = 1

Step-by-step explanation:

The standard form of a hyperbola is given as follows;

(x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1

The given equation is presented as follows;

9·x² - 36·x = 4·y² + 24·y + 36

By completing the square, we get;

(3·x - 6)·(3·x - 6) - 36 = (2·y + 6)·(2·y + 6)

(3·x - 6)² - 36 = (2·y + 6)²

(3·x - 6)² - (2·y + 6)² = 36

(3·x - 6)²/36 - (2·y + 6)²/36 = 36/36 = 1

(3·x - 6)²/6² - (2·y + 6)²/6² = 1

3²·(x - 2)²/6² - 2²·(y + 3)²/6² = 1

(x - 2)²/2² - (y + 3)²/3² = 1

The equation of the hyperbola  is (x - 2)²/2² - (y + 3)²/3² = 1.
