Answer:

Sides:  6 cms

Diagonal: 8.49 cms

Step-by-step explanation:

In a square the possible measurements to calculate are its sides and its diagonal, therefore we calculate both:

The perimeter of a square is calculated as the sum of its four sides. This is defined as a figure that has four equal sides, then:

4/24 = 6

Therefore each side measures 6 cm.

For the diagonal, we use pythagoras since it corresponds to the hypotenuse of a right triangle that is formed by drawing the diagonal:

c ^ 2 = a ^ 2 + b ^ 2

c ^ 2 = 6 ^ 2 + 6 ^ 2

c ^ 2 = 36 + 36 = 72

c = 72 ^ (1/2)

c = 8.49

What the diagonal means is 8.49 cm.

Answer:

[tex]P(x\geq 7)=0.1886[/tex]

Step-by-step explanation:

The variable x, that said the number of customer that will order a nonalcoholic beverage in a sample of n customers follows a binomial distribution. Because we have n identical and independent events with a probability p of success and (1-p) of fail.

So, the probability that x customers will order a nonalcoholic beverage is:

[tex]P(x)=\frac{n!}{x!(n-x)!}*p^{x}*(1-p)^{n-x}[/tex]

Where n is the size of the sample and p is the probability that a customer order a nonalcoholic beverage, so replacing the values, we get:

[tex]P(x)=\frac{10!}{x!(10-x)!}*0.51^{x}*(1-0.51)^{10-x}[/tex]

Now, the probability that at least 7 will order a nonalcoholic beverage is equal to:

[tex]P(x\geq 7)=P(7)+P(8)+P(9)+P(10)[/tex]

Where:

[tex]P(7)=\frac{10!}{7!(10-7)!}*0.51^{7}*(1-0.51)^{10-7}=0.1267\\P(8)=\frac{10!}{8!(10-8)!}*0.51^{8}*(1-0.51)^{10-8}=0.0494\\P(9)=\frac{10!}{9!(10-9)!}*0.51^{9}*(1-0.51)^{10-9}=0.0114\\P(10)=\frac{10!}{10!(10-10)!}*0.51^{10}*(1-0.51)^{10-10}=0.0011[/tex]

So, [tex]P(x\geq 7)[/tex] is equal to:

[tex]P(x\geq 7)=0.1267+0.0494+0.0114+0.0011\\P(x\geq 7)=0.1886[/tex]

Finally, the probability that in a sample of 10 customers, at least 7 will order a nonalcoholic beverage is equal to 0.1886

Since their corresponding angles are congruent and the corresponding sides are in proportion

Step-by-step explanation:

For ABD,

Sin (B) = (AD ÷ AB) =1

∴ AD = AB

and if AD = AB

⇒ AD = AC   (since AD 1 CB).

From triangle ACD,

Sin(C) = (AD ÷ AC)

Since AD = AC , Hence Sin (B) = Sin (C) = 1

Also From definition of similar triangles ABD and ACD are Similar (i.e their corresponding angles are congruent and the corresponding sides are in proportion)

To solve the equation 2x(x+3)-5(x+3)=0, distribute the terms within the parentheses and combine like terms. Then, use the quadratic formula to find the solutions of the quadratic equation.

To solve the equation 2x(x+3)-5(x+3)=0, let's distribute the 2x and -5 into the terms inside the parentheses: 2x^2 + 6x - 5x - 15 = 0. Combining like terms, we get 2x^2 + x - 15 = 0. Now we can use the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

In our case, a = 2, b = 1, and c = -15. Plugging these values into the quadratic formula, we get:

x = (-1 ± √(1^2 - 4(2)(-15))) / (2(2))

x = (-1 ± √(1 + 120)) / 4

x = (-1 ± √121) / 4

x = (-1 ± 11) / 4

So the two solutions are x = 10/4 and x = -12/4, which can be simplified to x = 5/2 and x = -3.

The answer would be 88 ft squared

Step-by-step explanation:

If you make the shape into a rectangle it would be 100 and  then subtract the amount that isn't filled in it would be 88.

The required area of the composite figure is 100 feet squared. The correct answer is option D.

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

To find the area of the composite figure, we need to add up the areas of the two rectangles.

The first rectangle has dimensions of 10 feet by 6 feet, so its area is:

10 ft × 6 ft = 60 ft²

The second rectangle has dimensions of 10 feet by 4 feet, so its area is:

10 ft × 4 ft = 40 ft²

The total area of the composite figure is:

60 ft² + 40 ft^2 = 100 ft²

Thus, the area of the composite figure is 100 feet squared. The correct answer is option D.

Anna opens her savings account with 'Y' dollars less than Alec's initial account amount, and she adds 'W' dollars more to her account each week compared to Alec.

Given that we want to compare the savings accounts of two students, Anna and Alec, let's assume that Alec opens his savings account with 'X' amount of dollars, and Anna opens hers with 'Y' amounts less than Alec, making her initial amount 'X-Y' dollars. Additionally, if Alec adds 'Z' dollars per week to his account, but Anna adds 'W' dollars more than Alec each week, Anna would be adding 'Z+W' dollars to her account weekly.

So, to fill in the blanks, you could say: Anna opens her savings account with 'Y' less than Alec used to open his account. Anna adds 'W' more per week to her account than Alec adds to his. By comparing this way, we can look at the differences in both the initial investment and the weekly contributions for each of the students' savings accounts.

You want c. We can get a and b from the chart by seeing that the horizontal distance from A to B is 8 and the vertical distance is 3. Otherwise,

a = |-4| + 4 = 8, horizontal distance

b = |-5| + |-2| = 3, vertical distance

To find the Length of Polygon Sides ('a') of a square polygon with an area of 48 mi², we apply the formula a = √Area. This gives a = √48 miles. This formula applies specifically to squares.

Given the area of the polygon is 48 square miles, to find the length of a side, we would first need to know the type of polygon.

For instance, if it's a square, the area is calculated by squaring one of its sides (Area = side²).

Here, to find the side length ('a'), we take the square root of the area. So, a = √Area.

Applying this to the given area, a = √48 miles.

However, please note that this formula is for a square.

Other polygons have different formulas for calculating such dimensions.

Answer:

79/9 * pi

Step-by-step explanation:

First find the circumference of the entire circle

C = 2 pi r

C = 2* pi* 5

C = 10 pi

The degree of MPN is 360 - 44 = 316

The fraction of the circle is 316/360 =79/90

Multiply that by the total circumference

79/90 * 10 pi

79/9 * pi

Answer:

s = 11π/9 units

Step-by-step explanation:

The arc length formula is s = rФ, where Ф is the central angle in radians.

Here the central angle is given as 44° and must be converted to radians:

44°       π

------ * ----- = 11π/45 radians

  1       180°

The length of arc MAN (not MPN) is    s = (5 units)(11π/45 radians), or

s = 11π/9 units

EASY! First we have to find the area of the back yard.

Step-by-step explanation:

[tex]A=12*10\\A=120[/tex]

So, we have to convert feet to yards(as it's in feet and we are doing our calculations in yards).

(And also, due to the fact it's squared, we have to square our coefficient as well).

The formula states we have to divide by 3, thus:

[tex]\frac{400}{3^{2} } =\frac{400}{9 }=44.444...[/tex]

Hmmm. Might be better if we do it the other way around. Might be simpler.

Thus:

[tex]120*9=1,080[/tex]

So then we divide 1,080 by 400, as the bag covers 400 feet

[tex]\frac{1080}{400} =2.7[/tex]

So, he needs 3 bags(as he cannot use two to cover the entire back yard). He will have a little left over, but that's okay, because he cannot buy 0.7 of a bag.

Then we multiply this by the cost!

[tex]3*25.99=77.97[/tex]

So, Kenneth would have to pay $77.97 and have a little left over!

Diameter of circle = D = ?

Answer:

Diameter of circle = [tex]D = 11.99[/tex] [tex]cm[/tex]

Step-by-step explanation:

We know that circumference of a circle is given by

[tex]C=\pi D[/tex]

[tex]D = \frac{C}{\pi}[/tex]

[tex]D = \frac{37.68}{\pi}[/tex]

Step-by-step explanation:

We want k such that ...

  PHP = k·USD

Then the value of k is ...

  PHP/USD = k = 12,451.60/350

  k = 35.576

__

700 USD will convert to twice as much as 350 USD, so ...

  700 USD = 700·35.576 PHP = 24,903.20 PHP

The constant of proportionality is 35.58. When you have 700 USD to convert, you will receive 24906.00 PHP.

To find the constant of proportionality, we can use the formula:

k = y / x, where k is the constant of proportionality, y is the dependent variable (number of Philippine Pesos received), and x is the independent variable (number of US Dollars).

In this case, we have:

k = 12451.60 / 350 = 35.58 (rounded to 3 decimal places)

Now, to find the amount of PHP given 700 USD to convert, we can use the same formula:

PHP = k * USD

PHP = 35.58 * 700 = 24906.00 (rounded to 2 decimal places)

Answer:

U = 71 degrees

Step-by-step explanation:

First you should set up an equation:

180 = b + (b - 19) + (180 - (b + 45))

Since there are 180 degrees in a triangle, set the sum of the angles equal to 180. And, since (u) and (b + 45) are supplementary angles that add up to 180, you can substitute (180 - (b + 45)) for (u).

Then, solve for (b):

180 = b + b - 19 + 180 - b - 45

180 = b + 116

64 = b

Find (b + 45):

64 + 45 = 109

Solve for (u):

180 - 109 = 71

u = 71

Miguel has started training for a race. The first time he trains, he runs 0.5 mile. Each subsequent time he trains, he runs 0.2 mile farther than he did the previous time.

What is the arithmetic series that represents the total distance Miguel has run after he has trained n times?

Answer:

The least number of times Miguel must run for his total distance run during training to exceed the distance of a marathon is 17.3 miles

Step-by-step explanation:.

Given parameters

Miguel first run = 0.5 mile

Subsequent run = 0.2 mile

This question is an arithmetic progression.

We'll make use of arithmetic progression formula to solve this

Formula:.

Tn = a + (n - 1)d

Where a = first term

n = number of terms

d = common difference

In this case

a = first run = 0.5 mile

d = subsequent run = 0.2 mile

So, Tn = a + (n - 1)d become

Tn = 0.5 + (n - 1) 0.2

Tn = 0.5 + 0.2n - 0.2

Tn = 0.5 - 0.2 + 0.2n

Tn = 0.3 + 0.2n

The arithmetic series of an arithmetic progression is calculated using

Sn = ½(a + Tn) * n

By substituton, we have

Sn = ½(0.5 + 0.3 + 0.2n) * n

Sn = ½(0.8 + 0.2n) * n

Sn = 0.4n + 0.1n²

b.

Since the race is 26.2 miles then the least number of times is given as

Sn ≥ 26

0.4n + 0.1n² ≥ 26.2

0.1n² + 0.4n - 26.2 ≥ 0

Using quadratic formula

n = (-b ± √(b² - 4ac))/2a

Where b = 0.4 a = 0.1 and C = -26.2

So,

n = -0.4 ± √(0.4² - 4 * 0.1 * ,26.2)/2 * 0.1

n = (-0.4 ± √10.64)/0.2

n = (0.4 ± 3.26)/0.2

n = (0.4 + 3.26)/0.2 or (0.4 - 3.26)/0.2

n = 3.46/0.2 or -2.86/0.2

n = 17.3 or -14.3

Since n can't be negative

n = 17.3 miles

The least number of times Miguel must run for his total distance run during training to exceed the distance of a marathon is 17.3 miles
