You have just bought a new puppy and want to fence in an area in the backyard for her to roam. You buy 100 linear feet from Home Depot and have decided to make a rectangular fenced in area using the back of your house as a side. What are the dimensions to maximize the area your puppy can roam

Answers

Answer:

50 ft * 25 ft

Step-by-step explanation:

Let the length of the rectangular area be x ft and the width of the rectangular area be y ft. You already have 100 ft of material for fencing. Also one side of your house is used in fencing.

The perimeter of the fence needed = x + 2y

Therefore:

100 = x + 2y

x = 100 - 2y

Also the area of the rectangular fence is:

Area (A) = length * breadth

A = xy

Substitute x = 100 - 2y

A = (100 - 2y)y

A = 100y - 2y²

Maximum area is at dA / dy = 0. Hence:

dA/dy = 100 - 4y

100 - 4y = 0

4y = 100

y = 25 ft

substitute value of y in x:

x = 100 - 2y = 100 - 2(25) = 100 - 50 = 50 ft

x = 50 ft

The dimension of the rectangular space is 50 ft * 25 ft

The probability that a radish seed will germinate is 0.7. A gardener plants seeds in batches of 8. Find the standard deviation for the number of seeds germinating in each batch.

Answers

Answer:

[tex]SD = 1.296[/tex]

Step-by-step explanation:

Given

[tex]n=8[/tex] --- batches

[tex]p =0.7[/tex] --- probability that a seed germinates

Required

Determine the standard deviation (SD)

This is calculated as:

[tex]SD = \sqrt{np(1-p)}[/tex]

Substitute values for n and p

[tex]SD = \sqrt{8 * 0.7 * (1-0.7)}[/tex]

[tex]SD = \sqrt{8 * 0.7 * 0.3}[/tex]

[tex]SD = \sqrt{1.68}[/tex]

[tex]SD = 1.296[/tex]

The standard deviation is approximately 1.296

A department store buys 100 shirts at a cost of ​$700 and sells them at a selling price of ​$10 each. Find the percent markup.

Answers

Answer:

42.8%

Step-by-step explanation:

Step one:

given data

A department store buys 100 shirts at a cost of ​$700

let us find the cost of 1 shirt

cost of 1 shirt= 700/100= $7 per shirt

The cost price per shirt = $7

We are given that the selling price = $10 per shirt

Step two:

The percent markup can be found as

percent markup= selling-cost price/cost price*100

percent markup= 10-7/10*100

percent markup= 3/7*100

percent markup= 0.428*100

percent markup= 42.8%

Write 4 4/7 as an improper fraction.

Answers

Answer:

32/7

Step-by-step explanation:

4/47

you multiply the denominator by the whole number which is 7*4= 28. You then add the numerator to 28 which is, 28+4=32.

the improper fraction is: 32/7

4 4/7 can be written as 32/7 in improper fraction.

To solve this problem

4 4/7 is a mixed number. It is possible to write it as follows:

4 + 4/7

The mixed number's first component, 4, is a whole number. The fractional portion of the mixed number is the second component, 4/7.

We must change the whole number component of 4 4/7 into a fraction with the same denominator as the fractional component in order to write it as an improper fraction. The denominator in this situation is 7. The result of the conversion is 4 * (7/7) = 28/7.

Now, we have:

28/7 + 4/7

Now, we just add the two fractions and simplify:

= 32/7

Therefore, 4 4/7 can be written as 32/7 in improper fraction.

What is equivalent distance of 35,000 centimeters in kilometers?

1 km = 1000 m

1 m = 100 cm

Enter your answer in the box.

Answers

Answer:

0.35km

Step-by-step explanation:

What is equivalent distance of 35,000 centimeters in kilometers?

Given the following

1 km = 1000 m

1 m = 100 cm

If

1 m = 100 cm

x = 35000cm

100x = 35000

x = 35000/100

x = 350m

Convert 350m to km

1 km = 1000 m

x = 350m

1000x = 350

x = 350/1000

x = 0.35km

Hence 35000cm to km is 0.35km

The coordinates of the point that is a reflection of Y(-4, -2) across the x-axis are (
,
). The coordinates of the point that is a reflection of Y across the y-axis are (
,
).

Answers

Answer:

The coordinates of the point that is a reflection of Y(-4, -2) across the x-axis are ( -4,2).

The coordinates of the point that is a reflection of Y across the y-axis are ( 4,-2).

Step-by-step explanation:

Reflection across x-axis

The rule used for Reflection across x-axis is that y-coordinate becomes negated while x coordinate remains same.

So,

The coordinates of the point that is a reflection of Y(-4, -2) across the x-axis are ( -4,2).

Because according to definition, x-coordinate remains same, while y-coordinate is negated. So x-coordinate = -4, y-coordinate = 2

Reflection across y-axis

The rule used for Reflection across y-axis is that x-coordinate becomes negated while y coordinate remains same.

So,

The coordinates of the point that is a reflection of Y across the y-axis are ( 4,-2).

Because according to definition, y-coordinate remains same, while x-coordinate is negated. So x-coordinate = 4, y-coordinate = -2
